The waterproof performance of EVA film is not fixed, but is a variable controlled by material formulation, structural design, and processing technology. Its core related factors can be summarized into three dimensions. The specific parameters under each dimension directly determine the strength of the waterproof ability and are also the key basis for actual selection:

The widespread application of TPU film (thermoplastic polyurethane film) in the packaging field stems from its comprehensive performance advantages. These advantages perfectly match the packaging's multiple requirements for protection, visual presentation, ease of use, and environmental adaptability. Specifically, they can be divided into the following five categories:
