If we talk about plastic bags, we are familiar with them, but if we tell you what PP Woven Bag or PE bag is, do you know what it is? If we ask you to tell us the difference between the two, can you tell us? Today we will introduce you to PP bags and PE bags and their differences, hoping to be of some help to you.

1. What are PP Woven Bag and PE bag?

First of all, we need to know that PP Woven Bag is a kind of plastic bag. This kind of plastic bag is mainly made of polypropylene. The production process mainly includes color printing and offset printing. The color of PP Woven Bag is brighter. It is generally a woven bag, which is a thermoplastic bag with good stretchability. PP Woven Bag is an environmentally friendly bag, non-toxic, tasteless and relatively transparent. It is generally used more in the packaging of cosmetics, accessories, toys, electronics and other industries. This kind of bag has good toughness and good quality, but it is better for packaging and not suitable for load-bearing.

PE bags are also a kind of plastic bags, but the material used for this kind of plastic bags is polyethylene. We all know that polyethylene is the best material. This material is not only non-toxic and tasteless, but also feels very good. The most important thing is that it can meet the standards of food hygiene packaging. PE bags also have good moisture resistance, acid and alkali resistance, and antioxidant properties, so they are more important and are also the most commonly used. PE bags are more commonly used for packaging various foods and some fiber products. They can also be used for our daily necessities. They have good ductility and will not be easily damaged when used.

2. What is the difference between PP Woven Bag and PE bag?

First of all, the materials used for PP Woven Bag and PE bag are different. PP Woven Bag uses polypropylene, but PE bag uses polyethylene. Polyethylene is a polymer with a relatively simple structure, but polypropylene is a semi-crystalline thermoplastic.

The difference between PP Woven Bag and PE bag lies in their respective characteristics. PE bag has no smell, no poison, feels like wax when touched, has good low temperature resistance, the lowest operating temperature can reach minus 100 degrees, and the chemical properties are relatively stable. It will not change when encountering strong acid and alkali. It will not melt in general solvents at normal temperature, and it has low water absorption and good electrical insulation, but its anti-aging property is not very good. PP Woven Bag has good mechanical properties, good toughness, good impact resistance, and will not change in strong acid, alkali and organic solvents.

Another difference is that the scope of use is different. PE bags are mostly used in plastic bags and some plastic films, but PP Woven Bag is mostly used in some industries to provide good packaging for various foods and beverages.
