Influence of additives in PE film in dry compounding and solutions

When PE is polymerized or PE film is formed into a film, a certain amount of additives, such as antistatic agent, slip agent, opening agent, etc., are generally added according to its use. These addit

Problems and Solutions of PE Film's Poor Lamination in Dry Lamination

That is, the composite strength is very low or zero, which cannot meet the requirements of customers at all, resulting in product scrap. Due to the particularity of the PE film production process, low

Problems that should be paid attention to in the precipitation of PVC protect...

In the process of producing stretched films, precipitation sometimes occurs, that is, a layer of hoarfrost is produced on the surface of the film or on the calender roll (or traction roll), which in s

Problems needing attention in the perforation of PVC protective film

There are three main types of perforation: 1. The material is too dirty and the fineness of the filter screen is not enough; 2. The four-roll calender is mixed with cold material; 3. The influence of

The problem of uneven thickness of PVC protective film film should be paid at...

The uneven thickness of the stretched film is mainly caused by two situations: 1. The film itself from the calender is not uniform in thickness, which will eventually cause the thickness of the stretc

Problems that need to be paid attention to when the PVC protective film shrin...

Excessive shrinkage has two meanings: 1. The film shrinks too much during the stretching process and cannot meet the width required by the product; 2. The thermal shrinkage of the film is too large du

Introduction of PVC protective film calendered biaxially oriented film
