Laminating adhesive are commonly known as PU adhesive for food packaging applications for combinations of different barrier properties and heat sealability.
These printed laminated structures are often prepared in multiple passes instead of a single step mainly due to the long drying oven in the case of solvent and water borne systems, or due to low immediate bond development in the case of solventless adhesive systems. Multilayer laminated film is made of multiple raw material layers chosen depending on the end use and needs.
Made of multiple layer film with barrier properties that are chosen. The laminated film with fine printing capabilities make the final product appear much more attractive whereas the barrier properties extend shelf life.
Laminated film is used in a wide range of flexible packaging applications such as for soft food packaging(snacks, sugar, seasoning, noodles, beverages, and biotic liquid packaging), pharmaceutical, personal care products, cosmetics, and many more. Laminated aluminum bag and rolls can be used on pizza wraps, beverage packaging, coffee bags and snack food packaging, as well as facial mask, bio medical packaging.
The laminated foil packaging is widely used in high speed production for flexible packaging because of its advantages for as a quick solution for increasing effiiciency.
Megabond polyurethane laminating adhesives have been widely used in the lamination of various muti layers film for the flexible packaging, from solvent-based to solventless.
