Common Causes of Water-Filled Ice Pack Seal Failure
Water-filled ice packs commonly experience seal failures during use, which not only affects their cooling efficiency but may also result in leakage. Understanding the causes of seal failure can help you use and maintain ice packs more effectively. Here are the main reasons for seal failure: 1. Manufacturing Process Issues Water-filled ice pack seals are typically formed through heat sealing or ultrasonic welding. If temperature, pressure, or time control during production is improper, the seal may be incomplete, creating weak points. These weak areas are more susceptible to breaking under pressure, friction, or external force during use. 2. Uneven Materials If the material thickness of the ice pack is uneven or inconsistent in quality, the seal may experience uneven stress, increasing the risk of breakage. When thinner or lower-quality material is used at the seal, it becomes more susceptible to deformation or breakage under pressure, which can affect the lifespan of the ice pack. 3. Overfilling Overfilling the ice pack...
