Which material is better for customized plastic bags
Every thing has its value and advantages, and the raw materials of plastic bags are also the same. Let's take PE as an example. PE is non-toxic, odorless, odorless, light and transparent, moisture-proof, anti-oxidant, acid-proof and alkali-proof. It is the recognized raw material of plastic bags all over the world. Why not just use PE for custom plastic bags? What do PP, PO, OPP, PPE, CPE, PVC, POF do?
That's because although PE is good, everything has double sides, and if there are strengths, it will be defective. The advantages of PE plastic bags are non-toxic, odorless, odorless, light and transparent, moisture-proof, antioxidant, acid-proof, alkali-proof. The same PE plastic bag also has defects, such as low transparency, complex extruded shapes are not easy to extrude, easy to oxidize, not easy to combine, and easy to be decomposed by ultraviolet light. The softening temperature is reached at around 150 ° C.
Therefore, when custom-made plastic bags, there is no so-called best raw materials, only the most suitable raw materials. PE is used for custom clothing handbags, PO is used for custom vest bags, and PE is used for custom ziplock bags. OPP is used for custom self-adhesive bags and PVC is used for custom shrink bags. Not to mention that other raw materials can't be made, only plastic bags made from these raw materials will be more suitable.
