BARRIER LAYERS. ITS USES AND A PROCESS FOR PREPARATION THEREOF

摘要

The invention relates to the use of melam deposited on a substrate, in applications requiring high humidity resistance, such as further processing comprising retort or metal deposition, or applications such as solar or display. Melam to melamine ratio (w/w) in the barrier layer is in the range from 3:1 to 50:1. The retortable laminate comprises two plastic films and in between a crystalline melam layer, the laminate having a lamination strength of about 2 N/inch or more as measured in a 90 degree tensile testing at 30 mm/min.
