The structure of the screw of the blowing film machine barrel is different

A special type of cling film blown out by a film blowing machine, using advanced technology to make fruits and vegetables durable and durable. To meet the needs of social products and environmental protection, plastic blow molding machines will continuously introduce advanced technology, adjust industrial models, and promote the plastic industry to move towards high-end. The produced film is suitable for various high-end film packaging. This type of film, due to its good barrier properties, moisture resistance, freshness preservation, oxygen resistance, frost resistance, and oil resistance, can be widely used for light and heavy packaging. Such as various meat products, Pickled vegetables, fresh fruits, fresh milk, liquid drinks, medical supplies, etc.

This special raw material requires a film blowing machine with high-end traction and drawing ability, ensuring the toughness and breathability of the product film. Food packaging is a field where film is widely used, and the high-end film blown out by the film blowing machine can be used for product packaging promotion, improving commercial value. Suitable for various high-end film packaging, plastic bag film, protective film, and so on. This type of film, due to its good barrier properties, freshness, frost resistance, oxygen resistance, moisture resistance, and oil resistance, can be widely used for light and heavy packaging.

Due to the different structures and materials used in the screw of the blow molding machine barrel, the temperature set during mold blowing also varies. The general temperature setting is based on the curve shape of the machine barrel from low to high, and then slightly reducing the temperature in the melting section before slightly increasing the temperature in the mold. Used for blowing high and low pressure polyethylene, the product is widely used in composite films, packaging films, agricultural covering films, textiles, clothing bags or films, and other packaging;

The main motor of the Dalian blowing film unit adopts frequency conversion speed regulation, which increases the stability of the main machine speed regulation and can save 30% of electricity. The screw material barrel is made of 38 chromium molybdenum aluminum, which has undergone nitriding treatment. The traction frame adopts a raised type, which can achieve optimal cooling effect regardless of the size of the blown film.

New film blowers produced in Dalian plastic film blowers machinery manufacturing industry include sheet film blowers, pe foam film blowers, multi-layer composite film blowers, color stripe film blowers, heat shrinkable film blowers, etc., which meet the packaging requirements of various products in the market. High end film blowing quality has won the favor of high-end product packaging. Nowadays, with the development of high-end technology in film blowing machines, blow molded films can also be used for various application technologies such as pharmaceuticals and food preservation, taking the path of manufacturing new types of film blowing machines.
