The other is to pay attention to the accumulation of resources, actively promote or promote the product. . In recent years, the development of most PE stretch film manufacturers is especially true in the market, and the trend of development is still relatively stable.

So why do manufacturers will develop so stable? In fact, in this regard, it is more than one, one is to implement a strict systemist, and strictly control the manufacturers. Anhydrous soaking method, in this way is also commonly used, which is completely charged into the liquid, placed on the filter paper after the seal, if there is an outward leak, then there is a problem of. In the water city pressure method, this kind of vacuum sampling is similar, through vacuum extraction, so that the internal and external pressure difference immersed in water, the inner gas exterior can be initially judged to determine its sealing performance.

By pumping the vacuum, the internal and external pressure difference occurs, and if its product is swollen or the recovery of the shape of the sample after the vacuum, the sealing performance of the sample is determined. With the freedom of their own independent fields, they play their own advantages in their own independent fields, and they compete in each other in the market. Compared with other peers, China Hand Use Stretch Film Manufacturers there are fewer manufacturers to collapse almost in recent years. In addition, there is another important thing to detect quality, this is a level that must pass.

If you have other related questions, please call our PE stretch film manufacturers. So, how can you manage to develop so stable? Next, you will make a simple introduction. manufacturers are very paying attention to quality issues, so that in recent years, the quality testing of stretch film is managed and secret IDE management. Even bankruptcy. Vacuum survey method, this is the method of detection that manufacturers is generally used. Stretch film manufacturers have opened strict testing of stretch film!

Moreover, MPE is a highly configured polymer. Further, the density of the material has an effect on the performance of the film. In the following, Xiaobian shared the PE winding film production formulation knowledge. PIB moves out of a process, usually takes three days.

Society is in progress, the era is changing, the appearance of the PE wrapping film makes the packaging of the product easier. The winding film formulation is added to the polymer or its masterbatch, and the other is incorporated into VLDPE.

As the number of copolymerized monomer C atoms in the wrap film, the increase in branches and crystallinity increases, the wound or kneading effect of the generated copolymer increases, the elongation of the wrapping film increases, the puncture strength and tear of the wrapping film The strength also increases. In addition, it is affected by temperature. PIB is a translucent viscous liquid, directly adds a special equipment or transformation equipment, generally using a PIB masterbatch.

The relative molecular mass distribution is narrow, wrap tape Manufacturers and the physical properties of the polymer can be accurately controlled, thereby increasing the performance of the winding film; and because the MPE molecular weight distribution is narrow, the processing range is narrow, and the processing conditions are difficult to control The 5% LDPE is often used to reduce the flatness of the melt viscosity and the wrapping film.

When the temperature is high, the viscosity of the wrap film; when the temperature is low, the winding film is not sticky, and the viscosity is greatly reduced
