Vacuum coated laminate and method for making same

摘要

A vacuum coated, liquid impermeable, vapor permeable laminate article and a method for making same are disclosed. The laminate may be formed of a netting material which is coated with a thin layer of vapor permeable polymer and subsequently passed over a vacuum forming drum to draw the polymer coating downward into the openings in the netting material. Vacuum coating produces thinned regions in the coating layer which provide greater vapor permeability. In laminates with sufficiently large openings in the netting material, the coating may directly contact a vacuum forming screen resulting in a plurality small indentations or cells within a single thinned region of the liquid impervious coating further increasing vapor permeability.
