How to distinguish between winding films and stretch film? In summary, it is a method of using a wrapping film and a stretch film, and it is desirable to increase the knowledge of the wrapping film and the stretch film. So our single, double-layer casting does not have three layers of latency in the data selection, and the formula interest is also high, so it is still ideal in three-layer coextrusion.

What we need to know is that the single-layer casting cannot be unique, and the application field is limited. This is because the casting line has the advantage of uniform thickness and high transparency, which is largely applicable to high-magnification pre-stretch requirements. Developed from single-layer to the second layer and three; now producing LLDPE stretch film based on casting method, early stretch film occupying the mainstream position by blown film.

The PE anti-static stretch film packaging must be stretched, and the tray mechanical packaging has direct stretching wrap film Suppliers and pre-stretching. The method is less tensile (about 15%, if the tensile multiplication exceeds 55% to 60%, the original yield point of the film is exceeded, the film width is reduced, the puncture performance is lost, and the film is easily broken). Widely used in foreign trade exports, food, drinks, films, papermaking, dyes, plastic chemicals, glass ceramics, electromechanical castings, etc.

The final use of the scissors to cut the tray mechanism package on the packaging card into a draw form. Abstract Analysis of PE anti-static stretch film characteristics The PE anti-static stretch film is a plastic film having viscous stretchable and wrapped wrap, which is self-adhesive not adhered to the subject, which is only the surface of the apparatus and 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
