PE film may sound unfamiliar to you, but in fact it is very widely used in our lives. Although PE film is a thin film, in fact its performance is very superior, which is why it is now popular in the market. This article will introduce to you in detail the materials, advantages, types, and applications of PE film. If you are interested in PE film, don't miss this article. let's start,
1. How is PE film made?
2. Advantages of PE film
3. Types and applications of PE film
PE protective film, full name Polyethylsene, is a film made of PE particles. Polyethylene is the simplest polymer organic compound. The production process of PE film is simple and has good performance.
PE film uses special polyethylene plastic as the main production material. Polyethylene is the simplest polymer organic compound, and it is also the most widely used polymer material in the world today. The production process of PE film is very simple. The dried polyethylene particles are heated and melted by the film blowing machine and then blown into a film. PE film has moisture resistance and low moisture permeability.
PE film is waterproof, very light in weight, very smooth in surface, and has certain heat resistance and stretchability. Therefore, PE film is often used as a protective material for products in processing and transportation.
We know that PE film uses special polyethylene plastic as the main material, so it is chemically stable. Compared with other materials, PE film will not rust. PE film has a smooth surface, soft texture and very light weight, but it has good durability and impact resistance. Research results show that the unwinding tension of PE film for compact board under 1 meter width can reach 3Kg, and its endurance can reach 29.4N. PE film is resistant to low temperatures and has good flexibility at low temperatures. It is non-toxic, tasteless and transparent, so it is often used as the best choice for people to package products. Its superior water resistance, insulation, and abrasion resistance enable it to protect the product well, keep the product in its original appearance, and ensure the quality of the product.
PE film can be divided into six categories according to its viscosity, namely: ultra-low-viscosity protective film, low-viscosity protective film, medium-low-viscosity protective film, medium-viscosity protective film, high-viscosity protective film, and ultra-high-viscosity protective film. PE film for compact board is an excellent packaging material, but the applicable packaging products of PE film with different viscosities are also different.
(1) Ultra-low viscosity PE film
The thickness of the ultra-low viscosity PE film for compact board is greater than 0.03mm, the peel strength is less than 5g/cm, and the stretch rate is greater than 400. Ultra-low-viscosity PE film for compact board makes it easy to stick and tear, and there is no residual glue, so it is suitable for packaging organic plates, instruments, displays, glass lenses, plastic lenses.
(2) Low viscosity protective PE film
The peel strength of the low-viscosity protective film is 10-20g/cm and the stretch rate is greater than 40. The low-viscosity protective film has stable adhesion, good adhesion, good peeling performance, and no glue residue, so it is suitable for packaging steel mirror plates, titanium metal, smooth plastic plates, etc.
(3) Medium and low viscosity protective PE film
The peeling strength of the medium and low viscosity protective film is 30-50g/cm, the adhesive force is stable, the adhesion is good, and the peeling performance is good, so it is suitable for furniture Polaroid board, stainless steel board, ceramic tile, marble, artificial stone, etc.
(4) Medium adhesive protective PE film
The peel strength of the medium adhesive protective film is 60-80g/cm. Uses: stable adhesive force, good adhesion, good peeling performance, no residual glue phenomenon, suitable for surface protection of fine grain frosted boards and general hard-to-stick materials.
(5) High viscosity protective PE film
The peel strength of the high-viscosity protective film is 80-100g/cm, and the stretch rate is greater than 400. The high-viscosity protective film has stable adhesion and is suitable for fine-grain frosted boards, aluminum-plastic panels, and hard-to-stick plastic sheets.
(6) Ultra-high viscosity protective PE film
The peel strength of the ultra-high-viscosity protective film is above 100g/cm, so it has a high viscosity and is suitable for hard-to-stick materials such as rough-grained aluminum plates.
