How to solve the membrane conductivity problem



Three-tier co-extrusion blown film machine, compared with similar equipment has a higher yield, plasticizing good products, low energy consumption, the advantages of simple operation, completely solve the film falbala and winding size top problem, make the product quality on a new step. The produced films have high transparency, puncture, high toughness, low temperature enthusiasm, good compound fastness, and anti-crimp. This membrane is good for its obstructing, preservation, moisture-proof, frost proof, oxygen resistant, oil resistant, can be widely used in weight packaging. If all kinds of fresh fruit, meat, pickles, fresh milk, liquid beverage, medical supplies, etc. Now, we will briefly introduce the operation procedures of the three layers of the film blowing machine, hoping that it will help you.

Based on the great harm of static electricity, and most of the time it is due to the lack of antistatic property of plastic, it is necessary to use antistatic plastic in these situations. However, most plastics are electrical insulators, and they must be modified if they are to have electrostatic dispersion (ESD) and electromagnetic shielding (EMI) properties. This modified plastic is called antistatic or conductive plastic.

Using extrusion, blow molding, injection and other molding methods, they can be made into various profiles, containers, films, industrial parts and so on. As one of the categories of products, conductive film is the use of common plastic with the blend of conductive material or filler by blow molding, or on the basis of the existing film made by plating metal. Its volume resistivity is in commonly 103 ~ 108 Ω · cm range, can be widely used in microelectronics devices, integrated circuit chip packaging and cable shielding, missiles, electromagnetic shielding, etc.

The three layers of heat-shrinkable packaging film are a kind of new environment-friendly and non-toxic heat-shrinkable packaging material which is produced by the main raw materials of PE and PP. Originated in Italy in the early 1990s, it is widely used in developed countries such as Europe and the United States. Convenient is mainly used in beverage, food, daily chemical products, audio and video products, books, medicine packaging, electronic components and other articles for daily use, particularly suitable for supermarket goods packaging and store shelves.

The main features of this product are: high transparency, good gloss, can clearly show the appearance of products, improve the sense of perception, and reflect the high grade. Big shrinkage rate, up to 75%, good flexibility, can be of any shape for packaging of goods, and through special craft processing the three-tier co-extrusion film contraction force control, meet the requirements of different commodity packaging on the contraction force. The welding seal has good performance and high strength. It is suitable for manual, semi-automatic and high-speed automatic packaging. Good cold resistance, can be in - 50 ℃ maintain flexibility without brittle, suitable packing materials storage and transportation in a cold environment.
