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

The three-layer co extrusion blown film machine is an efficient, high-precision, and stable plastic film manufacturing equipment. It can produce various thin film products with different structures and properties through multi-layer extrusion and blowing technology, which are widely used in food packaging, agriculture, building materials, textiles, medical and other fields. With the advancement of technology and market demand, it is believed that the three-layer co extrusion blown film machine will continue to innovate and improve in future development.

Due to the use of different raw materials for each layer of film, different characteristics can be selected according to needs, such as strength, transparency, waterproofing, etc. Meanwhile, due to the tighter bonding between each layer, the physical properties of the film are better. The three extruders of the three-layer co extrusion blown film machine can work simultaneously, completing the production of three-layer films in one go, saving time and labor costs. Due to the independent adjustment of working temperature and extrusion speed for each layer of extruder, energy consumption can be adjusted as needed, reducing energy waste.

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

Frequently used is polyethylene film: Polyethylene film, abbreviated as PE film, is a common plastic film with excellent toughness, tear resistance, impact resistance, and chemical corrosion resistance. It can be used in the packaging industry, such as food bags, pharmaceutical bags, daily necessities bags, etc.

Polypropylene film: Polypropylene film, abbreviated as PP film, is a type of film with high transparency, glossiness, and softness, which has good antioxidant and weather resistance properties. It has a wide range of applications in the packaging industry, and can be used to make food packaging bags, clothing packaging bags, etc.

Polyester film: Polyester film, abbreviated as PET film, is a type of film with good transparency, flatness, and high temperature resistance. It is commonly used in fields such as electronic product packaging and heat transfer printing.

Nylon film: Nylon film, abbreviated as PA film, is a type of film with high strength, tensile strength, and wear resistance, suitable for making packaging bags with good airtightness, frozen food packaging bags, etc.

The main structural components of the three-layer co extrusion blown film machine include an extruder, a die head, a stretching roller, a cooling roller, a winding machine, etc. The extruder is the core component of the entire equipment, mainly composed of screws, cylinders, and heating and cooling systems. The screw extrudes plastic raw materials from the feeding port through rotation, and melts and mixes them along the barrel. The mold head is a key component that controls the shape and thickness of the film, and can adjust the structure and size of the formed part as needed. The stretching roller and cooling roller are used to stretch and cool the film during the extrusion process, ensuring the firmness and quality of the film. The winding machine rolls up the blown film for subsequent packaging and transportation.

The three-layer co extrusion blown film machine is a device used for manufacturing plastic films. It consists of a machine and three levels of plastic extruders.
