ABA three-layer co-extrusion blown film machine is suitable for producing three-layer plastic film, where A represents two layers of the same material, and B represents the middle layer of different materials. This structure can provide a certain degree of strength and tensile strength advantages, making it especially suitable for the production of express bags and other products that require high tensile strength.
Courier bags usually need to have a certain tensile strength and durability to ensure that items can be protected during transportation and can withstand a certain amount of weight and tension. The co-extrusion blown film machine using the ABA three-layer structure can use high-strength materials (layer B) in the middle layer, while using the same material (layer A) on both sides. This design can enhance the overall strength and tensile force of the film.
In addition to structural design, the physical properties of the film can be further optimized by adjusting parameters such as extrusion speed, temperature control, and material selection during the production process. For example, using high molecular weight raw materials or adding special additives can increase the strength and tensile force of the film.
In general, the ABA three-layer co-extrusion blown film machine can provide better film performance and quality in the production of express bags and other products that require high tensile force, ensuring that the product performs well during transportation and use.
