Films lamination is a process in which two films are bonded together into on film which maintains all the properties of its components. the result is a film that is stronger and stiffer, with better barrier and sealing properties, that protects printing and contents, with heat resistant, or anti-chemical attack, etc.
Flexible packaging laminates are common films used in the flexible packaging industry, as they can be used for a wide range of applications owing to their properties. Several methods are used to bond the film layers, such as using a Solvent-based adhesive or Solvent-free adhesive on flexible packaging lamination.
Solvent-based, in which the solvent evaporates in the drying process. However, these adhesives are considered less environmentally and human friendly.
Solventless, in other words do not contain any solvents, are preferable and contain two substrates that react on contact between them to create the adhesive, without the need for drying.
