Advantages of anti-static release films
In the process of goods transportation, due to the bumps in the process will produce a certain amount of static electricity, if the packaging can use anti-static release film, for the goods is a good protective effect, and will also reduce accidents, especially some flammable and explosive items will be packaged with anti-static release film, obviously, anti-static release film in daily sales more advantageous, favored by some manufacturers.

The role of PET release film in production
Release film is coated with silicone release agent on the surface of environmental protection material PE/OPP/PET film, so that it can show a very light and stable release force, used for various organic pressure sensing adhesives, different organic pressure sensing adhesives, such as: hot melt adhesives, pressure adhesives, rubber system pressure sensing adhesives, etc... The release force required for the release film is different, and the release film is also called peeling film, separator film, separation film, release film, silicone oil film, anti-stick film. In the process of daily production of double-sided adhesive, PET release film plays an important role and role, today I will share with you the role of PET release film in production.
How to repair the broken release film
The release film will be damaged during use and preservation, and its damage in use can be temporarily repaired and permanently repaired. Temporary repair methods include water repair and paper repair method. Water replenishment method: scrub the damaged area, cut a piece of release film without holes slightly larger than the broken place, dip in water and paste it on the hole, drain the air between the two membranes, and press flat. Paper repair method, agricultural film slightly damaged, with paper dipped in water and pasted on the damaged place while wet, generally can be used for about 10d.
Analysis of the characteristics and uses of seven plastic film products
1. Biaxially oriented polypropylene film (BOPP) Biaxially oriented polypropylene film is a transparent flexible packaging material developed in the 20s of the 60th century. It is a special production line to mix polypropylene raw materials and functional additives, melt mix, make sheets, and then stretch to make films.
Overview of embossed films
Take the most widely used polypropylene cast film (CPP), for example, CPP is a non-stretching, non-directional flat extruded film produced by melt cast quenching. Compared with blown film, it is characterized by fast production speed, high output, good film transparency, gloss and thickness uniformity. At the same time, because it is a flat extruded film, the subsequent processes such as printing and lamination are extremely convenient, so it is widely used in the packaging of textiles, flowers, food and daily necessities.
A brief introduction to the manufacturing of plastics and the synthesis of resins
The basic raw materials for the manufacture of plastics were initially based on agricultural and sideline products, shifted to coal and coal tar products from the 50s of this century, and gradually shifted to oil and gas from the <>s.
Conductive plastic
Conductive plastics are functional polymer materials that mix resin and conductive substances and process them by processing plastics. Mainly used in electronics, integrated circuit packaging, electromagnetic wave shielding and other fields.
Introduction of the Functional Properties of PET Films
PET is a short form of plastic, PET plastic is usually used in food, medicine and other packaging; can be used as packaging bottles, such as cosmetics bottles, medicine bottles and so on; can also be used in automotive parts, mechanical equipment, etc., can be said to be very useful. PET film is a kind of plastic film, it has the characteristics of PET plastic, specifically, the characteristics of PET film:
