The advantages of blown film mainly include the following aspects
High production efficiency:
The entire film is formed in one unit production in the blown film process, which simplifies the production process.
The equipment is relatively simple, with low investment and fast production speed, and can quickly produce a large number of film products.
Excellent film performance:
The width and thickness of the film can be effectively adjusted, and films of different specifications and sizes can be customized according to customer needs.
The extrusion temperature is uniform, which avoids the problem of unstable quality of the film edge and improves the overall quality of the film.
The film can be stretched in both directions, and the obtained film has uniform mechanical properties, high strength and good toughness.
High raw material utilization rate:
The blown film process has less waste and low cost, and can make full use of raw materials and reduce waste.
It is suitable for the manufacture of co-extruded multi-layer films. The utilization rate of raw materials and the performance of the film can be further improved through multi-layer co-extrusion technology.
Few welds and wide width:
The number of welds of the film produced by the blown film process is relatively small, which reduces the defects and weaknesses that may occur during the welding process.
The width of the width, that is, the width of the film is large, can meet the needs of wide-width films in different fields.
Easy to operate:
The film blowing equipment occupies a small area, is easy to operate, and is suitable for use in various production environments.
The high degree of automation can reduce manual intervention, improve production efficiency and the stability of product quality.
Wide application:
The film produced by the film blowing process has a wide range of applications, such as food packaging, medical supplies packaging, agricultural covering film, etc.
It can meet the different requirements of different industries for film performance, specifications and sizes.
