What different types of films can be produced by the three-layer co extrusion blown film machine?

The three-layer co extrusion blown film machine is an efficient, stable, and multifunctional film production equipment. It has a wide range of applications in food packaging, medical supplies, agricultural covering films, and other fields, playing an important role in promoting the development of the plastic film industry. With the continuous progress of technology and changes in market demand, the three-layer co extrusion blown film machine will continue to undergo technological improvement and innovation to meet the growing demand.

Compared to traditional single-layer blow molding machines, three-layer co extrusion blow molding machines have many advantages. Due to the use of three-layer co extrusion technology, the film produced by this equipment has better mechanical strength and physical properties. Secondly, multi-layer co extrusion technology not only improves product quality, but also reduces production costs. Because low-cost plastic materials can be used as intermediate layers in the manufacturing of composite films, and high-performance materials can only be used in the surface layer. The three-layer co extrusion blown film machine has high production efficiency and can simultaneously produce multi-layer films, meeting the needs of large-scale production.

What different types of films can be produced by the three-layer co extrusion blown film machine?

The three-layer co extrusion blown film machine can produce ordinary plastic films. Ordinary plastic film is a common type of film that can be widely used in the packaging industry. Ordinary plastic films have good transparency, flexibility, and sealing properties, and can be used to package various commodities. For example, bagged food, daily necessities, medicines, cosmetics, etc. can all be packaged using ordinary plastic film.

Secondly, the three-layer co extrusion blown film machine can also produce functional films. Functional films refer to films with special functions added to ordinary plastic films. For example, a three-layer co extrusion blown film machine can add a gas barrier layer to produce gas barrier films. Gas barrier films have good barrier properties for oxygen, water vapor, and fragrance, which can maintain the freshness and taste of food, cold drinks, daily necessities, and other commodities. In addition, the three-layer co extrusion blown film machine can also add an anti-static layer to produce anti-static films. Anti static film has the function of preventing static accumulation and avoiding fire risks caused by static discharge, and can be used in industries such as electronic products.

Once again, the three-layer co extrusion blown film machine can also produce special purpose films. Special purpose films are films with high performance and special purposes. For example, a three-layer co extrusion blown film machine can produce composite films. Composite films are formed by combining thin films of different materials. Composite films can have different properties and functions, such as waterproofing, oil resistance, high temperature resistance, corrosion resistance, etc. In addition, the three-layer co extrusion blown film machine can also produce special purpose films such as multi-layer films, alternating layer films, and textured films.

In practical applications, the three-layer co extrusion blown film machine can select suitable extruders and die heads according to different plastic materials, and adjust corresponding process parameters to produce film products that meet specific needs. At the same time, it can also change the performance and function of the film by adding special additives and fillers, making it have special functions such as anti-static, flame retardant, and UV resistance.
