What are the application scope of the three-layer co extrusion blown film machine

The main components of a three-layer co extrusion blown film machine include an extruder, a disperser, a molten square barrel, an extrusion die head, a stretching machine, a calendering roller, and a winding machine. The extruder is the core part of the entire equipment, which can adjust the temperature, pressure, and speed of the extruder according to the physical characteristics of different particles to control the thickness and quality of the film.

Compared with traditional single-layer or double-layer blow molding machines, the film produced by the three-layer extruder has better oxygen isolation, moisture resistance, and freshness preservation performance, which can adapt to more packaging needs. In addition, the three-layer co extrusion blown film machine has the advantages of high production efficiency, easy operation, and small footprint, and has received widespread attention and application. It should be noted that when operating the three-layer co extrusion blown film machine, adjustments need to be made according to different types of particles to ensure the stability of the workflow and the quality of the produced products. At the same time, it is necessary to pay attention to regular maintenance and upkeep of the equipment to extend its service life.

What are the application scope of the three-layer co extrusion blown film machine

1. Food packaging: Making various food bags and packaging bags.

2. Drug packaging: Production of drug bags, drug packaging bags, etc.

3. Building waterproofing: manufacture various coatings, waterproofing materials, etc.

4. Agricultural coverage: Produce agricultural coverage materials for covering fruits and vegetables such as eggplants, watermelons, and grapes for preservation.

The three-layer co extrusion blown film machine is a composite equipment that produces three-layer composite films from different materials through three extruders. The three-layer co extrusion blown film machine has the characteristics of high strength, high transparency, good tear resistance, good airtightness, good barrier, low permeability, non aging, and environmental protection. It is widely used in food packaging, pharmaceutical packaging, agricultural coverage, building waterproofing and other fields.

The three-layer co extrusion blown film machine requires three extruders to extrude the raw materials for the inner, middle, and outer layers respectively. Each extruder can be independently controlled, so that the thickness of each layer of film can be accurately controlled, ensuring the consistency and stability of the film.
