The same is true for customized ziplock bags. Each material has advantages and disadvantages. Let's take PE as an example. PE is tasteless, odorless, light and transparent, moisture-proof, acid-resistant and alkali-resistant. It is a recognized custom-made material for self-sealing tapes. Why not just use PE for custom self-sealing tapes? What about other materials.
That's because PE is good, but everything has two sides, and there are advantages and disadvantages. The advantages of PE ziplock bags are non-toxic, odorless, light and transparent, moisture-proof, acid-resistant and alkali-resistant. The same PE ziplock bag also has shortcomings, such as low transparency, easy to oxidize, not easy to combine, and easy to be decomposed by ultraviolet rays. The softening temperature is reached around 150°C.
Therefore, when the ziplock bag is customized, there is no so-called best material, only the right material. PE is used for ziplock bags for customized food, PO is used for ziplock bags for customized clothing, PE is also used for customized ziplock bags, OPP is used for customized self-adhesive bags, and PVC is used for customized shrink bags. Don't mean that other materials can't be made, but ziplock bags made of these materials will be more suitable.
