Say goodbye to air conditioning sickness! Injecting cold water can keep you cool for 3-4 hours. This summer, rely on it to prolong your life! 2026/7/20

As the triple heat period arrives, the temperature keeps soaring, and the oppressive and humid weather makes people feel unwell all over. Air conditioners and fans can lower the temperature, but prolonged direct exposure to them can cause dizziness, headaches, dry skin, and joint discomfort. Online celebrities' ice patches and disposable ice bags are highly stimulating and have short cooling durations, resulting in poor experience. In fact, many people don't know that the PVC hot water bottles commonly used in winter are actually "specialized physical cooling tools" suitable for extremely hot summers - they can be used for two purposes and easily unlock the coolness of summer. In the minds of most people, PVC hot water bags are only suitable for use in winter. But from a different perspective - considering the material and heat management properties - they are actually suitable for all seasons. In summer, using them as a physical cooling tool is both practical and novel, and it also gives this classic item a new value. High-quality thickened PVC material, with gentle heat dissipation and excellent sealing performance, enables the release of coolness in a slow and even manner. When used in summer, simply inject chilled tap water (it is recommended to keep the temperature at 8-12℃, and do not put it in the freezer as it may cause the material to harden and crack), and you can enjoy a stable cool sensation for approximately 3-4 hours. Compared to air conditioners and fans, this method does not consume electricity, has no noise, feels gentle on the body, and is less likely to cause "air conditioning sickness", making it especially suitable for people who are sensitive to temperature changes, such as mothers and infants, post-operative rehabilitation patients, and the elderly. We specialize in manufacturing high-quality PVC hot water bottles. From raw materials to production processes, we strictly control every step. The product is thickly reinforced to prevent explosion, leakage and wear, and has excellent toughness. It effectively reduces the risks of leakage and damage. It breaks the traditional concept that hot water bags can only be used for heating, providing warmth in winter and coolness in summer, suitable for all seasons, and has outstanding cost-effectiveness. No complex operations are required. It can be used immediately when needed. It is an ideal small item for cooling off at home, at work, or in dormitories - using reliable quality to ensure comfort throughout the seasons.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle，cervical spine hot water bag, plush hot water bottle.......

The hot water bottle is meticulously manufactured. Its high quality ensures safe and reliable use throughout the four seasons. 2026/7/10

The safe use of hot water bottle is not affected by seasons. It is particularly crucial to properly store and maintain them during the summer. High temperatures accelerate the aging and softening of PVC materials, shortening the product's lifespan. During the autumn and winter, reusing them is prone to damage and leakage, which can lead to cold or hot burns. We adhere to the principle of prioritizing safety. In the product labels and usage guidelines, we have emphasized important precautions such as storing in a dark place, draining accumulated water, keeping away from heat sources, and avoiding direct sunlight. This helps to comprehensively reduce potential safety hazards at the end-user level. Yuefeng adopts standardized production processes. The raw materials are selected from compliant and environmentally friendly PVC materials, which have excellent temperature resistance and flexibility, and are suitable for both cold and hot usage scenarios. The production process strictly controls key procedures such as heat sealing, sealing, and molding, eliminating common problems like seams, leaks, and thin bottoms. All products undergo multi-dimensional manual and equipment inspections before leaving the factory, adhering to unified quality standards for each category to ensure stable product quality and small batch-to-batch variations, and meeting the needs of various bulk purchases and long-term cooperation. Changzhou Yuefeng Plastic Products Co., Ltd. has been deeply engaged in the hot water bottle industry for many years. They specialize in manufacturing a full range of PVC products such as regular hot water bags, hand-warming plug-in hot water bags, cold compress hot water bags, and cervical-specific hot water bags. The factory focuses on meticulous workmanship and stable quality control. They do not engage in exaggerated promotion. They only aim to provide customers from all over the country with high compatibility and low after-sales service quality supplies. They are a reliable cooperation manufacturer for long-term bulk purchases and custom gift orders.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle，cervical spine hot water bag, plush hot water bottle.......

Fear of heat, fear of leakage, fear of idleness - The hot water bottle is pre-filled in one go, precisely matched to your needs. 2026/6/29

Fear of heat, fear of leakage, fear of idleness - The hot water bottle is pre-filled in one go, precisely matched to your needs.In response to the three core pain points commonly faced by consumers when using hot water bags - fear of scalding, fear of leakage, and the fact that they are only used for one season and then easily become idle - we have developed three differentiated hot water bags specifically tailored for different groups of people and sales channels. Starting from aspects of safety, durability, and year-round practicality, we precisely match the needs of different channels. Type 1: Addressing the "Fear of Heat" pain point - Cover with Cervical Model Many customers have reported that the surface of traditional hot water bags is too hot, making them unsuitable for use by the elderly and children. The cervical model features a longer curvature, evenly distributed water volume, and a flatter bag body. When in contact with the skin, the heat is more evenly dispersed and is less likely to accumulate at a single point; combined with the physical insulation of the outer fabric cover, the overall feeling is significantly more comfortable. This not only enhances comfort but also provides safety redundancy. Recommended scenarios: gift channels, elderly care institutions, and mother and baby stores for associated sales. Type 2: Addressing the "fear of leakage" pain point - Spiral leak-proof large-capacity model "Leakage" is the biggest trust crisis for hot water bags. We adopt a dual leak-proof structure consisting of an inner plug and an outer cover (the inner plug is responsible for sealing, and the outer cover prevents loosening). Even after being slightly squeezed after being filled with water, the sealing performance remains stable. The large-capacity model is specifically designed for lower-level distribution channels such as rural markets and community supermarkets. Users value "durability, reliability, and ease of use". Recommended scenarios: wholesale of daily necessities, school canteens, and factory labor protection purchases. The third category: Addressing the "idle" problem - multi-purpose, hot and cold, portable model Many users find that the hot water bottle is only used for about two or three months each year, and they hesitate in making a purchase decision. However, the dual-purpose cold and hot model precisely addresses this psychological issue - it can be used for cold compress in summer, warmth retention in winter, and joint heat therapy in spring and autumn. This makes it a frequently used item throughout the year. Recommendation scenarios: outdoor goods stores, sports rehabilitation equipment stores, and online young consumer groups.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle，cervical spine hot water bag, plush hot water bottle.......

PVC hot water bottles are not exclusive to winter! 2026/6/29

PVC hot water bottles are not exclusive to winter!The summer temperature is high, so it is important to take good care of the  PVC hot water bottle when it is left idle. After use, empty the internal water in time, wipe the bag clean, and place it in a 【ventilated area to dry naturally】. Avoid direct sunlight and high-temperature baking, and prevent the material from aging and hardening. When storing, place it gently without heavy pressure or folding, do not fold it into a dead shape, keep it away from sharp objects and corrosive household chemicals. Just place it in a 【dry storage room】 for storage, which can effectively extend the product's service life. The demand for hot water bags among the general public is becoming increasingly diverse. A single design is insufficient to meet all scenarios. The multi-category  PVC hot water bottles from Changzhou Yuefeng Plastic Products Company are customized for four major needs: daily warmth, portable heating, shoulder and neck care, and cold compress relief. They precisely match the usage scenarios of end users and are suitable for various purchasing needs. Winter-Spring - Warm Protection Period[It is not necessary to elaborate on the fact that the stocking-up period begins in October each year and lasts until March of the following year. However, what deserves attention is the "post-spring cold spell" period - the two weeks after the heating stops. This is often the second peak season for hot water bags. At this time, it is advisable to recommend the large-capacity basic model to customers, emphasizing its emergency attribute of "supplementing heat sources".] Summer and Autumn - Cold Compress and Maintenance PeriodThe real opportunities lie in the off-season. Sports injuries are more common in summer, especially among basketball and running enthusiasts. Having a cold compress-specific hot water bag ready, filling it with ice water and attaching it to the knees or ankles is a cost-effective physical pain relief solution. Additionally, for female customers during their menstrual periods in summer, a small hot water bag is used for abdominal heat therapy, and the demand is actually stable. It is recommended that the purchasing party prepare goods in summer by focusing on small-capacity, strap-equipped styles, and can be promoted in the off-season with the "cold and hot dual-use" label. Throughout the year · Sub-health Toning PeriodThis period is not limited by seasons and is suitable for people with discomfort in their shoulders, neck, and lower back. The hot water bag for the cervical spine has evolved from a "heating tool" to an "office companion". Many users use it as a fixed item for heat application during lunch breaks or relaxation before sleep. These customers have a high rate of repeat purchases and have a clear preference for the material of the cover (such as velvet, cotton and linen). This makes it an appropriate point to differentiate and sell.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle，cervical spine hot water bag, plush hot water bottle.......

The self-cultivation of a durable hot water bottle 2026/6/22

As PVC products that come into direct contact with the skin and hold hot water, the "cleaning challenge" of hot water bottle is often a test of their quality. Many purchasing clients focus on whether the surface stains can be removed, while Changzhou Yuefeng pays more attention to whether the product can still maintain its sealing property and material stability after repeated cleaning and alternating hot and cold conditions. Easy to clean, stemming from a clean baseWe use high-purity PVC raw materials and adopt an integrated molding process for the inner liner and outer layer. This means:The surface is dense without micropores. Common stains can be wiped clean with a damp cloth. Stubborn stains can be rinsed with a neutral detergent, and the gel will not turn white or harden;The threaded openings and stoppers are made with precise molds. Even after repeated twisting during cleaning, they still fit tightly and will not "give way" and leak due to thermal expansion and contraction. Selection and Maintenance Summary Suggestions: For procurement, you can choose the appropriate models such as regular heating, hot compress, or cervical spine-specific based on the usage scenario. All products of Yuefeng have undergone strict quality control and are suitable for various channels including home use, gifts, and supermarkets. After daily use, clean thoroughly, dry completely, and store properly. Avoid sharp objects and high-temperature environments. This not only ensures the usage experience but also significantly extends the reuse life of the products, resulting in lower comprehensive usage costs and more prominent long-term economic benefits.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle，cervical spine hot water bag, plush hot water bottle.......

Changzhou Yuefeng Plastic Products Co., Ltd: Whether the Cervical spine hot water bottle is good or not? Just look at these 3 points and you'll know. 2026/6/8

When purchasing a cervical spine hot water bag, the appearance is often quite similar. However, it is the several overlooked details that truly determine the usage experience and durability. Whether it's sitting at a desk for long periods or during long drives, neck heat therapy is a common way to relax. Choosing the right product is particularly crucial. We have sorted out three core concerns based on actual production and customer feedback. 1. Fit: The curvature and softness should be just right.The cervical spine hot water bag is not an ordinary hot water bag with a new name. Its value lies in "being able to hold and fit securely". If the curvature is too flat, it will slip off; if it is too curved, the contact surface will be small. At the same time, the softness and hardness of the PVC material also affect the experience: if it is too hard, it will not fit well; if it is too soft, it will collapse after being filled with water. We have been continuously following customer feedback and adjusting the mold curvature and material formula to ensure that after being filled with warm water, it can naturally support the curve at the back of the neck. II. Safety: Sealing structure and heat resistance are the bottom lineHot water bags are most prone to leakage. If a neck heat pack leaks, it can easily cause burns. A reliable cervical hot water bag should have smooth and hairless threaded teeth, and the sealing gasket should be resistant to aging and have good elasticity. At the same time, PVC materials should have good heat resistance stability to avoid softening, deforming or developing odors after long-term contact with hot water. Each batch of products from Changzhou Yuefeng undergoes sealing tests and heat resistance inspections to ensure stable shipment. III. Durability: Resistance to Fatigue in Daily UseBusinesses dread after-sales troubles the most. Frequent operations such as filling water, screwing the cap, and squeezing are the daily routines of the cervical heat bag. We will add a specific proportion of stabilizers and plasticizers to the materials to ensure a soft feel while enhancing the fatigue resistance lifespan. A simple way to judge: When turning the bottle cap smoothly without any abruptness, it indicates that the mold accuracy and assembly process are in place. The core of the hot water bag for the cervical vertebrae is not about being fancy, but about being reliable. For our customers, our suggestion is: first get samples, conduct tests, and then assess the batch stability. Do not blindly pursue low prices, nor blindly believe the promise of "absolutely no leakage". Use standards to verify quality.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle，cervical spine hot water bag, plush hot water bottle.......

Which scenarios did the PVC hot water bottles you purchased be used in? 2026/5/25

Purchase a batch of hot water bags and distribute them to different end users. The "hidden requirements" for the products actually vary. Changzhou Yuefeng Plastic Products Co., Ltd.  breaks down the common usage scenarios and helps you match them appropriately, reducing selection errors. Scene 1: Daily household heating - "Stability" is keyFor ordinary families, they purchase hot water bottles mainly to warm the hands and feet of the elderly and children. Users are most concerned about: no leakage when filled with hot water, the screw cap does not come off easily when tightened, and the surface of the bag is clean and free of dust. For such scenarios, fancy functions are not necessary, but each bag must be "convenient to use". The regular model of Yuefeng hot water bag has uniform thickness, neat sealing edges, and focuses on providing a "reliable" experience. Scene 2: Cold Compress for Sports Injuries - "Resilience" RequiredThe cold compress bag contains a mixture of ice water. The bag body tends to harden and become brittle when exposed to low temperatures. If the formula is not properly designed, the bag will crack when pressed by the user right out of the refrigerator. Therefore, the core of the cold compress product is not "heat resistance", but "cold resistance toughness". Yue Feng's cold compress hot water bag has specially adjusted its performance at low temperatures. The bag remains soft and bendable at around 0°C, making it suitable for ice compressing areas such as knees and ankles. Scene 3: Cervical Spine Fatigue Heat Therapy - "Secure Placement"Users with cervical spine issues are usually those who sit for long periods. They place a hot water bag behind their necks and use it by relying on the weight of their heads. This requires the middle area of the bag to fit snugly around the curve of the neck and not to crack at the creases when repeatedly bent. The Yuefeng Cervical Hot Water Bag has optimized the curvature on the mold and strengthened the sealing strength of the bending areas, ensuring that users can comfortably use it and you can rest assured.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle，cervical spine hot water bag, plush hot water bottle.......

Changzhou Yuefeng Plastic Products Co., Ltd: Cold compress model and cervical model. The more detailed the scene description, the more stable it needs to be. 2026/5/25

Ordinary hot water bags contain only hot water, and the contents are relatively simple. But cold compress models need to contain a mixture of ice water, and neck support models need to be repeatedly bent to fit the neck - due to different usage scenarios, the production standards also need to change accordingly. Changzhou Yuefeng sets individual production processes for each product type. Cold compress product: Low temperature does not become hard or crackedThe cold compress bag is filled with ice water or ice blocks at a temperature of 0-4℃. Ordinary PVC will become hard and brittle when exposed to low temperatures, and will crack even with a slight squeeze. Changzhou Yuefeng Plastic Products Co., Ltd.  has adjusted the low-temperature toughness in the cold compress product formula to ensure that the bag body remains soft at low temperatures and is not prone to cracks. The edge sealing and threaded openings have also undergone low-temperature impact tests, and are not "just talk on paper". Cervical Support: Fits snugly, resistant to repeated bendingThe cervical hot pack needs to fit the curve of the neck. When used, it is often pressed against the head and repeatedly bent. We optimized the thickness distribution of the middle area of the bag body on the mold to make the force distribution at the bending points more uniform, avoiding single-point fatigue. At the same time, we widened the edge width to enhance the tear resistance. Users feel comfortable when they lean on it, and you don't have to worry about receiving complaints about "it leaks after using twice".Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle，cervical spine hot water bag, plush hot water bottle.......

Make good use of the unused hot water bottles in summer for a refreshing and comforting experience. 2026/5/11

Make good use of the unused hot water bottles in summer for a refreshing and comforting experience. The weather is getting increasingly hot, and many people think that hot water bags are exclusive to winter and can be put away once used. In fact, unused hot water bags don't have to "sleep" in a dormant state! Here are a few simple and effective summer usage tips to enhance the happiness of your home life at a low cost. Please read and follow the safety instructions at the end before using.Fill the hot water bottle with room-temperature water (with a water temperature of around 25℃ is suitable), and the water volume should be controlled at 2/3 of the bag's capacity. After expelling the air inside the bag, tighten the lid. A soft and comfortable cooling pad is ready. It doesn't have the bone-chilling cold sensation like hard ice bags. When it fits against the body, it is warm and cooling. When watching TV or using a mobile phone, placing it under your body can significantly relieve the feeling of heat. If you are afraid of heat when sleeping at night and don't like the cold air from the air conditioner blowing directly on you, you can put the filled with cold water hot water bag beside your feet (avoid direct contact with the skin). It will slowly dissipate heat, gently balance the body temperature, and help you sleep peacefully.Before daily outings, you can pre-fill with cold water and seal it properly, then put it in an insulated bag and place it on the car seat. This can alleviate the burning sensation of the seat after being exposed to the sun.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle，cervical spine hot water bag, plush hot water bottle.......

When it's hot, just use a PVC hot water bottle. Just keep these points in mind and you'll be fine. 2026/5/11

When it's hot, just use a PVC hot water bottle. Just keep these points in mind and you'll be fine.PVC hot water bottles are occasionally used in summer as well. If you happen to need one, here are a few tips to consider. There are not many, but they are quite practical.Water temperature: In winter, hot water bags can be filled with a little hotter water, but not in summer. It is recommended that the water temperature not exceed 50 degrees. A simple way to judge is to test the hot water with the back of your hand. It should feel warm but not too hot.Wrapping: At any time, do not let the hot water bag touch the skin directly. Find a dry towel, an old T-shirt or a cloth bag to cover it. The thickness should be at least two layers of cotton.Time: It is recommended to control the usage time to about 10 minutes each time. Set an alarm and remove it when the time is up. Do not use the hot water bag while doing other things, as it is easy to forget the time.Check: In summer, rubber products tend to age easily. Before each use, take a look to see if there are any cracks, discoloration or bulging. If so, do not use it and replace it with a new one, which is not expensive.Attention for the public: Elderly people, children, diabetics or those with less sensitive skin are advised not to use hot water bags in summer. If you really need to use one, ask a family member to help determine the water temperature and usage time.Changzhou Yuefeng Plastic Products Co., Ltd. specializes in the production of hot water bottle, PVC hot water bottle, hand warm hot water bottle, cold water sack, insert hot water bottle，cervical spine hot water bag, plush hot water bottle.......
