Ordinary plastic bag material summary.kraft paper pouch pouches

　　PE material: It is divided into high -pressure materials (LDPE) and low pressure materials (HDPE)

　　The appearance of the high -pressure material looks smooth, the feel is soft, and the toughness is better. Many handbag raw materials are made of high -pressure materials. The outer packaging of many products is made of high -pressure materials. There are also large -scale industrial use packaging bags.

　　Low -pressure materials are very tensile and high in hardness. They are widely used in shopping malls and various procurement markets. Most of the supermarket plastic bags are made of low -pressure materials. The easiest way to distinguish between high and low voltage, tearing by hand, generating white marks proves that low pressure is low, because low pressure is high density, so white marks will produce white marks. Non -white marks produce well tensile. Generally, high pressure.

　　PP material: The material is harder, but the transparency is relatively high, more clear, the tension is not very good, and it is easy to explode. Most of them are used for gift packaging, as well as finished clothing sales. The new clothes we buy are packed in plastic bags and a layer of double -sided rubber seal is usually a PO rubber bag.

　　The PP rubber bag is very transparent, and it feels very slippery, but it is very strong and crispy. If it is folded, there will be creases. There is no folding PE rubber bag. Because of the good transparency, it will be seen in packaging gifts. The grade is very high.

　　OPP material: The material is the most crisp, the most transparent, not enough tension, but the most explosive mouth, and the printed is the easiest to decolor. If there is no gap, it is difficult to tear, but you can tear it out if you have a little gap.
