Dry Laminating Adhesives (for Food / Daily Commodity Packaging)
A single plastic film has various properties, including transparency, flexibility, moisture permeability, gas barrier properties, and chemical resistance. However, at least two types of films need to be bonded together to protect the content, for which dry laminating adhesives are used.
Extrusion Laminating Primers
While dry lamination uses a solid plastic film, extrusion lamination involves a process of extruding polyethylene as the sealant, which is melted at around 310 degrees centigrade, and bonding the sealant with the primary base material by using an anchor coat (primer.)
