Reversibility paper lamination

Different demands are placed on a pigment which is targeted for covered or laminated printing. In this technique, a reverse impression is printed onto a plastic film and laminated by means of one or two component adhesives, laminating resins and wax onto another substrate such as paper, aluminum foil, or polymer foil. These substances may adversely affect pigment performance. For high gloss applications, a normal impression is covered with a clear plastic film. 

Separator or Release Sheets. Separator or release sheets are used to free the reverse side of a laminate either from pressure padding material or the adjacent laminate normally they are paper of the glassine type, coated with release agents. 

The basic materials cited above being on the decline, the reverse can be expected for the remaining basic materials, i.e. plastic, paper and board, and films, foils and laminates. 

Lamination improves the barrier properties of the plastic. Lamination with paper is done to have strength and printability. Laminations enable reverse printing, in which the printing is buried between layers and thus not subjected to abrasion and can add or enhance heat sealability. Lamination using laser rather than adhesives are also used for thermoplastics.
