What are the processing materials of plastic ziplock bags wholesale？
In modern life, plastic ziplock bags are used frequently, but few people know what the processing materials of plastic ziplock bags are?What kind of material is the quality of processed plastic ziplock bags safe?Today, Qiming will introduce you what are the processing materials of plastic ziplock bags?
Low-pressure polyethylene and linear low-density polyethylene are new varieties of polyethylene that have been mass-produced in the international market in recent years.Because of its excellent impact strength and puncture resistance,resistance to environmental stress cracking and low temperature performance,in particular, it can be used to make micro-films with low use cost.Therefore, it is widely used in plastic ziplock bags.It can blow low pressure, high pressure, linear low density polyethylene film,not only suitable for their new material blown film, but also suitable for their recycled plastic blown film,stable performance and reliable quality.
1.The main material of the plastic ziplock bag is low-pressure polyethylene, which has the highest transparency, but the tension is not enough, easy to burst, and the printing is the easiest to decolor.
2.There is also a PVC material. The hardness of the material can be selected according to the needs, and the transparency can also be selected according to the needs. Because there are super transparent materials, ordinary materials and frosted materials, they have good tensile strength and are not easy to tear. Not easy to burst.
3.PP material. The material body is harder, but the transparency contrast is high, clearer, and the pulling force is not very good! Easy to burst!
4.PO material. The material is brittle, the transparency is not high enough, there is a little red, and the tension is not very good.
Qiming’s best-selling plastic ziplock bags wholesale style is Aluminized ziplock bag.Material is PET/AL/PET/PE.Its advantages are strong air barrier performance, oxidation resistance, water resistance and moisture resistance. Strong mechanical properties, high blast resistance, puncture resistance and tear resistance.
