As a plastic processing method, blown film extrusion has a wide range of applications. The following are the main application areas of blown film extrusion:
1. Packaging industry
Food packaging: The blown film extrusion process can produce films with high transparency, strong tensile strength and high flexibility. These films play an important role in food packaging, such as fresh-keeping bags, food bags, beverage bottle labels, etc. These films can not only effectively protect food, but also provide moisture-proof and oxygen-proof functions to ensure the quality and safety of food.
Commodity packaging: The film extruded by blown film is an ideal choice for commodity packaging due to its transparency and flexibility. It can clearly display the appearance and characteristics of the product, enhance the attractiveness and market competitiveness of the product.
Medical supplies: In the medical industry, blown film extrusion films can be used for medical packaging, operating room supplies, etc. These films need to meet high hygiene standards, and the blown film extrusion process can produce films that meet the requirements to ensure the safety and reliability of medical supplies.
2. Agricultural field
Films extruded by blown film also have important applications in agriculture, such as agricultural mulch. Agricultural mulch can maintain soil temperature and humidity, promote crop growth, and increase crop yields. The blown film extrusion process can produce agricultural mulch films suitable for different crops and climatic conditions to meet the diverse needs of agricultural production.
3. Other fields
Construction field: The film extruded by blown film can also be used in the production of building materials, such as waterproof film, thermal insulation film, etc. These films play the role of waterproofing, heat insulation, and heat preservation in buildings, improving the comfort and energy saving of buildings.
Industrial field: In the industrial field, the film extruded by blown film can be used for various industrial packaging, protective films, etc. They can protect industrial products from damage and ensure the integrity and safety of products.
4. Application of multi-layer co-extrusion blown film equipment
Multi-layer co-extrusion blown film equipment is an advanced application form of blown film extrusion technology. It can co-extrude a variety of functional plastics into a blown film to form a green multifunctional film without adhesive. This film also has important applications in aerospace, optics and other fields, and can meet the high performance requirements of film materials in these fields.
