As a material widely used in packaging, transportation and other fields, bubble film rolls have an important impact on product quality and performance.
1. Raw materials of bubble film rolls
The main raw materials of bubble film rolls are polyethylene (PE) and ethylene vinyl acetate copolymer (EVA). Polyethylene has good flexibility, impact resistance and chemical resistance, while ethylene-vinyl acetate copolymer has good elasticity and wear resistance. These two materials are processed into bubble film rolls through special processes, which are lightweight, high-strength, shock-proof and buffering.
2. The production process of bubble film rolls
⑴ Extrusion molding: Polyethylene and ethylene-vinyl acetate copolymer particles are melted at high temperature and extruded into a film shape through an extruder.
⑵ Bubble formation: The extruded film is bubble-formed through special equipment to form a film with independent bubbles.
⑶ Compounding: Composite the bubble film with base materials such as paper and plastic film to enhance the strength and wear resistance of the bubble film roll.
⑷ Cutting: Cut the composite bubble film roll into products of different sizes and shapes.
⑸ Packaging: Pack the cut bubble film rolls for transportation and sales.
3. Quality control of bubble film rolls
⑴ Raw material inspection: Conduct quality inspection on polyethylene and ethylene-vinyl acetate copolymer particles to ensure that the quality of raw materials meets the requirements.
⑵ Online testing: During the production process, the thickness, width, bubble size and other parameters of the bubble film roll are tested online to ensure stable product quality.
⑶. Finished product inspection: Inspect the appearance, size, strength and other aspects of the produced bubble film rolls to ensure that the products meet customer requirements.
⑷Storage and transportation: Properly store and transport bubble film rolls to prevent moisture, deformation and other adverse phenomena.
In short, the production process of bubble film rolls includes extrusion molding, bubble formation, compounding, cutting and packaging. Through strict control of raw materials, production processes and finished product quality, high-quality bubble film rolls can be produced to meet market demand.
