Dry type composite packaging film and solvent-free composite have to differ?

composite packaging film in production, the composite pattern can be divided into: extrusion compound, dry compound, complex wet, without solvent. The present is the most used dry composite and solvent-free composite. What's the difference between two types of composite, and respectively used for which kind of packaging? Dry type composite is put adhesive through the anilox roll plastic wine evenly coating to carry plastic base membrane, after oven to dry, in the compound of kunduz fit into a composite film of a compound. Dry type composite packaging film and application of a wide range, excellent erosion resistance, resistance to chemical media more for packaging containing alkali, hot, strong corrosion such as oil content of the packaging, can also be applied to cosmetics fragrance, emulsifier and other ingredients, in particular, some need high temperature cooking packaging, very has the advantage.

composite packaging film

and solvent-free composite packaging film and dry composite difference is not use organic solvent, not only avoid the pollution of organic solvent volatilization caused to the environment, and there's no need to solvent evaporation drying operation section, directly reduces the cost of production, and eliminates the composite substrate vulnerable to the effects of solvent and high temperature drying damage, let the size of the packaging film stability performance is better.

this two ways of composite packaging film each have each advantages, when choosing which one to use composite way, to the first reference packaging elements such as the nature of the content, weight, and second, not all of the composite structure of solvent-free composite method can be used. If I am unable to determine, also can seek advice more experienced packaging film manufacturer.
