What are the differences between PE, PO, PP, OPP and PVC plastic packaging?

PE material: the material is soft, but the transparency is not enough, other materials are higher, more Meng. Good tension, not explosive mouth!

PP material: the material is hard, but the transparency is relatively high, clearer, the tension is not very good, explosive mouth!

PO material: material is crisp, transparency is not high enough, more than PE material, but also a little white, the pull is not very good

OPP material: the body is the most brittle, the highest transparency, tension is not enough, but the most explosive mouth. And printing the most easy to bleaching

PVC material: material is also soft with hard, may need to purchase raw materials according to the guest, transparency can also be according to the required, because there is a transparent material, ordinary material and abrasive material, good tensile strength, not easy to tear, is not easy to burst, because between two layers of material are machine beer together
