The main products are: container bags, paper-plastic composite bags, valve bag, woven bags, etc. The products are widely used in chemical, construction, new materials, food, agriculture and animal husbandry and other industries.
What are the similarities and differences between PP and PE materials?
From the appearance, the woven bag is not difficult to make. Very simple, but is such a woven bag, let us feel very simple, not difficult. This is a very difficult thing to do. Don't look at such a simple bag, it has been used for many years, but there are only two kinds of materials. One is polypropylene, called pp woven bag, and the other is polyethylene, called pe woven bag. So what are the similarities and differences between these two kinds of woven bags?

From the appearance, the woven bag is not difficult to make. Very simple, but is such a woven bag, let us feel very simple, not difficult. This is a very difficult thing to do. Don't look at such a simple bag, it has been used for many years, but there are only two kinds of materials. One is polypropylene, called pp woven bag, and the other is polyethylene, called pe woven bag. So what are the similarities and differences between these two kinds of woven bags?
According to some common woven bag materials in the market, woven bag manufacturers analyze the similarities and differences between PP and PE materials as follows:
Step 1: Polyethylene
Also known as PE plastic is a thermoplastic resin polymerized from ethylene. Polyethylene plastic woven bags have good performance, but polyethylene is sensitive to environmental stress, poor heat resistance and aging, and is used less in China.
2. Polypropylene
Generally speaking, most woven bags in China are made of polypropylene. Polypropylene is a thermoplastic resin made from propylene polymer with isotactic substance. Random and interregular three configurations, its strength. The rigidity and transparency are better than polyethylene, and the shortcomings of poor low temperature impact resistance and easy aging can be overcome by modification and addition of antioxidants.
In plastic products, plastic braid is a flexible material with high fracture strength, which is related to its molecular structure, crystallinity, drafting direction and additive type. If the plastic woven fabric is measured in terms of specific strength (strength/specific gravity), it is higher than or close to the metal material.
At room temperature, the plastic woven cloth is actually completely immune to water erosion, and the water absorption rate is less than 0 within 24 hours. 01%, water permeability is also very low. At low temperatures, it gets crunchy. Plastic braids don't mold.
Similarities:
The appearance is the same. From the appearance, there is no difference between the two materials of woven bags. Without special testing, no one knows if it's polypropylene or polyethylene, so you can't tell which is which. In addition, his function is basically the same, are loaded powder products or loaded granular products, the use is the same. At the same time, there is one of the most important similarities, that is, the manufacturing process of these two different materials of woven bags is the same, and it is exactly the same, without any difference.
The difference:
Since there are so many woven bags of two different materials, first of all, the biggest difference between them is the difference in material. This alone brings us great inconvenience in use and use. Polypropylene woven bags are now the most widely used because of its low price and widely accepted by people. The function of polyethylene woven bag is similar, but the price of the same specification is about one-third higher, so it is really not suitable for disposable woven bag packaging products.
So when you choose the material, you should look at the difference between the two, see if it is the material you want, and then order
