Plastic water bottles, particularly those produced by a specialized Plastic Water Bottle Factory(https://www.kx-bottle.com/product/), are commonly manufactured using materials such as PET, PP, and Tritan. These plastics are chosen for their durability, lightweight properties, and transparency. However, each type of plastic has specific temperature tolerance thresholds. When exposed to heat beyond the recommended range, some plastics may begin to soften or deform. For example, PET bottles are designed mainly for cold beverages and may warp if filled with boiling water. On the other hand, Tritan and PP materials offer better heat resistance but still require users to follow proper usage guidelines. This heat sensitivity causes many manufacturers to include temperature warnings on bottle packaging or product labels to ensure consumer safety.
