Supply PE plastic bag manufacturers and suppliers in Shunde District

Bag is a sealed bag made of polyethylene. It is a green product. It is tough and durable, reusable, and can be printed with advertisements and marks. It is mainly used for product packaging,
for storing food, jewelry, Medicines, cosmetics, frozen foods, stamps, etc., are moisture-proof, waterproof, insect-proof, and prevent things from scattering. It plays a summary role and gives buyers a neat and standardized image.
It can also be reused and will be sealed with a light touch. It is tight, non-toxic and odorless, has good flexibility, can be sealed at will, and is very convenient.
Bags are a type of plastic bags, which are divided into high-density and low-density bags. High-density ones are tougher, have high transparency, feel stiff, and are relatively expensive.
The plastic bags generally provided by supermarkets are high-density bags. Low-density bags are the most common bags that are sold in the market and are soft to the touch. They are of inferior quality, have poor transparency, and are cheap. The film is made of , , and as the base material, with special resin added, and then through several special processes. Processed with additives. It can be made into high and low pressure films. It has good stiffness, high strength, good printability, and good heat sealability. It is also tasteless and odorless and meets the hygiene requirements of food packaging. The biggest advantage of the film is that the protected products are not polluted, corroded, scratched during production, processing, transportation, storage and use, and the original smooth and shiny surface is protected.
Can be made into various types of high and low pressure bags, ziplock bags, etc.

Differences caused by materials and production processes
Polypropylene, according to different processing methods, is divided into blown film production methods High-strength, high-transparency films can be obtained by flat film method and stretching.
It's polyethylene. Different materials also have different effects
The material body is soft, but the transparency is not high enough and other materials are relatively hazy. It has good pulling force and is not easy to burst.
The material body is relatively hard, but the transparency is relatively high and clear. The pulling force is not very good and it is easy to burst.
The material body is relatively brittle, the transparency is not high enough, it is more cloudy than the material, a bit white, and the tensile strength is not very good.
The material body is the brittlest, has the highest transparency, does not have enough pulling force, but is the most susceptible to explosion. And the printing is the easiest to discolor.
The material body can be soft or hard. You can order the material according to the needs of the customer. The transparency can also be based on the needs, because there are super transparent materials, ordinary materials and frosted materials. They have good pulling force and are not easy to tear. , and it’s not easy to burst because the two layers of material are pressed together using a machine.
