Summary
Function: pvdc multilayer co-extruded film manufacturer is a composite bag that combines various sheets with different properties based on double-layer co-extrusion technology. It is a one-time molding process that can comprehensively integrate the characteristics of various sheets to meet different functional requirements of plastic flexible packaging.
From the perspective of manufacturing process and cost, the advantages of multifunctional co-extruded plastic films mainly include: not limited by product models, able to effectively meet different packaging scenarios; the more layers stacked, the more flexible the overall design and the lower the cost. For example, the amount of composite resin required for specific properties can be reduced to a thinner thickness, with single-side thickness as low as 2 to 3μm, which can further reduce the amount of expensive epoxy resin used; only injection molding process is needed, which can effectively reduce product costs. pvdc multilayer co-extruded film.
Main uses:
1. Partial replacement of composite bags
Multifunctional co-extruded films can be used to replace some structures of composite bags. For example, composite plastic films with PA/PE inner layers can be replaced by PA/PE co-extruded films; composite plastic films with high barrier structures can be replaced by co-extruded films containing EVOH. For products requiring high barrier properties, such as fruit juice, tomato sauce, and crystal jelly, packaging with multifunctional co-extruded plastic films can effectively prevent issues like discoloration and odor. pvdc multilayer co-extruded film.
2. Used in automatic packaging machines
The multilayer structure of multifunctional high barrier pvdc multilayer co-extruded films used in automatic packaging machines, combined with the use of multifunctional pvdc multilayer co-extruded films and automatic packaging machines, can effectively reduce the labor intensity of manual packaging. One automatic packaging machine can replace the labor efficiency of three production workers. This is equivalent to the labor efficiency of 15 to 20 workers when using manual packaging, which not only alleviates recruitment difficulties but also reduces labor costs.
Secondly, the function of high barrier pvdc multilayer co-extruded films can achieve automatic filling on automatic packaging machines, effectively reducing secondary contamination caused by manual packaging of products with high safety and health requirements such as food and medicine.
In addition, multifunctional pvdc multilayer co-extruded film manufacturers do not require composite processing technology, which can better control the solvent content, providing reliable assurance for the safety and environmental protection of food, medicine, and other products. High barrier pvdc multilayer co-extruded film.
3. As buffer packaging for electronic devices and electrical products
Function: pvdc multilayer co-extruded film manufacturers as buffer packaging for electronic and electrical products have outstanding advantages. The traditional structure is PE/PE/TIE/PA/TIE/PE/PE. This type of buffer packaging is also called "vacuum packaging bag." Common plastic film materials have excellent physical properties such as puncture resistance, compression resistance, excellent high barrier, durability, and light blocking, which requires the combination of various polymers with different properties.
