1. Nylon: To seal the package, because the nylon will absorb water when it meets the air, nylon's main characteristic is strong penetration resistance, suitable for bone products. However, nylon bags are easy to wrinkle and shrink. Nylon thickness is generally 15um.
2, crisp, breathable and moisture permeability is relatively good, tensile and barrier properties are relatively poor, feel more brittle. OPP thickness is generally 30um.
3, tensile properties are better, pull off the force is better. There are milk white PE (extinction) and transparent PE two. Feel softer.
4, very good, good printing effect, suitable for packaging bags. The feel is particularly brittle, and the rustling of the rustle on the hand is particularly loud. PET thickness is generally 12um.
5. CPP: Good transparency.
Note: The shrinkage of various materials is about 4%-5%. The packaging bag used by our company is generally compounded with nylon and PE. Various materials have been sampled and backed up for sealing.
