Valve body: Always check the corrosion and wear of the inner wall of the valve, especially for valves used in harsh process conditions such as corrosive media, high pressure differences, and cavitation. It must ensure its compressive strength, corrosion resistance, and grinding performance.

Waterproof and breathable membrane is a material that many users are more interested in, because just from the name, it is somewhat unclear what the principle is. This is the charm of technology, which cannot allow us to easily understand the mystery.

In order to make the surface of the plastic film have good ink adhesion and enhance the firmness of the printed matter, the PE plastic bag is subjected to surface activation treatment before printing.

The viscosity of the PE protective film is too high, but it is also not acceptable if it is low, so that the products produced will hardly meet our requirements. If the viscosity of the PE protective film is low, we must find a way to increase its viscosity. The specific method is as follows:

When it comes to pe original film, we should be familiar with it, because there are many products that need to be used, such as our mobile phones, which also need to be used, and there are many types of protective films, pe The protective film is one of them, so what are the requirements for the use environment and bonding of the PE protective film?

Polyethylene is a crystalline material that is easy to crystallize. If it is not cooled rapidly, the light transmittance and elongation at break will inevitably be reduced. The cooling effect of blow molding is poor, the crystallinity is high, and the transparency of the film (thin and soft transparent sheet) is low.

Although there are many types of stretch films and their uses are different, they also have their common characteristics. After all, their basic raw materials are the same, so there is no difference in use, that is, there are some other differences in performance. Then we will briefly describe what they have in common.

PE stretch film is a new type of packaging material in the logistics industry. It can be widely used in the centralized packaging of various goods. It is widely used in foreign trade export, papermaking, hardware, plastic chemical industry, building materials, food and pharmaceutical industries. The production of this material has great requirements on temperature, so what kind of requirements does it have on temperature during production:

PE stretch wrap film is mainly used in the packaging industry, regardless of the shape and size of the product, etc., the advantages of stretch wrap film as a special feature work well. However, some users found that the reason for the phenomenon of things being scattered when carrying things is that the stretch wrapping film itself of the packaging has changed, and the slack of the stretch wrapping film has decreased a lot.

We can supplier many raw materials, but today the protagonist is printed PE Film.Looking this kind design printing PE Film, you can feel soft and thickness. Yes, it is use laminating film. Let we look it’s raw material – PE.
