How to solve metallocene polyethylene blowing film easy to break

What you will learn inside this guide

 This article will tell you how to solve metallocene polyethylene blowing film easy to break. It consist of three parts:

1.Characteristics of metallocene polyethylene film

2.Material selection and formula design

3.High performance packaging mPE film production process control

Metallocene polyethylene has been widely used in food packaging and industrial packaging due to its excellent properties. Metallocene polyethylene resin because of its special molecular weight distribution and composition distribution, determine the polymer processing technology and processing equipment and traditional materials are different. In the process of metallocene thin film production, the normal operation of equipment and strict control of technological conditions must be ensured, in order to achieve stable product quality.


Due to the narrow molecular weight distribution, low molecular content rarely, chemical extraction resistance and pollution resistance performs good, thin film viscosity is low; It also does not contain superhigh molecular matter, so it has fewer crystal points. MPE film has excellent physical and mechanical properties, such as: puncture resistance, impact resistance, high tension, tear characteristics. The film has good heat sealing performance, low heat sealing temperature, wide range of heat sealing temperature, low melting peak, shortening heat sealing time, good sealing performance, greatly reducing leakage and fracture.

In addition, mPE film also has food packaging needs moisture-proof, air-proof, oxidation resistance, oil resistance, frost resistance, cooking resistance, chemical corrosion resistance, non-toxic, tasteless, does not affect the food nutrients, maintain food flavor, good printing performance, easy to open, and other characteristics, so it has become a high-performance packaging film commonly used resin materials. General LLDPE film is easy to produce migration and oxidation in the presence of grease. Under the action of alkali, acid or strong surfactant, thermal sealing weld will often break and cause pollution.
