The effect of composite packaging bags is good, please remember these tricks
Release time:2020-03-07
In the composite process design of composite packaging bag materials, it is important to note that structural design and process design complement each other, and also to consider some factors in the composite packaging bag process design. Mastering these will enable the creation of better composite packaging bags.
In the composite process design of laminated packaging bag materials, it should be noted that structural design and process design are complementary, and some factors that should be considered in the process design of laminated packaging bags should also be noted. Mastering these can lead to better laminated packaging bags
I. Laminated Packaging Bags Complementarity of Structural Design and Process Design
For laminated packaging bags, in addition to good structural and functional design, there must also be a practical and feasible process design to fully utilize the functions of the structural design. In the production of laminated packaging bag materials, structural design and process design are complementary. Process design should be carried out simultaneously with structural design, as the feasibility of the process often constrains the structural design; conversely, products with the same structure can also be processed using various different processes to produce laminated packaging bags with identical structures but different functions
II. Laminated Packaging Bags Factors to Consider in Process Design
1. Raw Materials
Whether the source of raw materials is stable, and whether specific raw materials can be procured, including various general film substrates, various functional substrates, various inks, adhesives, functional coating materials, various resins, additives, etc
2. Equipment Factors
Adaptability of printing equipment to materials. Whether it has a reverse device, the maximum and minimum specifications of adaptable substrates, the printing quality level that printing equipment can achieve, such as the types of gravure, flexographic, and screen printing equipment and their impact on printing quality
Compounding specification range of laminating equipment. The type of laminating equipment is an important factor in determining the performance of composite materials. Dry and wet laminating machines can produce various packaging materials and are the most widely used, but their cost is relatively high. Extrusion lamination includes single-layer coating, single-layer extrusion lamination, twin or multi-tandem extrusion lamination, co-extrusion lamination, etc. Tandem laminating equipment can laminate 5-13 layers of materials at one time, and co-extrusion lamination can extrude functional materials
Specification range of materials cut by slitting equipment. Types of materials to be slit, minimum and maximum slitting dimensions, etc
Types of bags that can be made by bag-making equipment. Such as three-side seal, stand-up pouch, zipper bag, etc., and the maximum and minimum specifications for bag making
3. Influence of Product Requirements on Process
It mainly refers to the requirements of packaging materials on the type of film adhesives and solvents used and the amount of solvent residue
