Claims8
A heat shrinkable film antifogging laminate useful for packaging comprising, in order:
- (a) a heat shrinkable film comprising a polymer having at least 80% by weight polyethylene terephthalate polymer, wherein said film is biaxially oriented in the range of about 5% to about 55%, said film having an outer surface and an inner surface;
- and
- (b) an adhesive layer;
- and
- (c) a film having a heat shrinkage of at least 5% less than (a);
- and
- (d) a coating consisting essentially of an anti-fog agent.

A package containing a food comprising a substrate in combination with laminate derived from a heat shrinkable film laminate comprising in order:
- (a) a film which has been shrunk by heat from a heat shrinkable film comprising a polymer having at least 80% by weight polyethylene terephthalate polymer, wherein said film is biaxially oriented in the range of about 5% to about 55%, said film having an outer surface and an inner surface;
- and
- (b) an adhesive layer;
- and
- (c) a film which is derived from a film having a heat shrinkage of at least 5% less than (a);
- and
- (d) a coating consisting essentially of an anti-fog layer wherein the laminate covers a surface portion of a substrate which supports a food.
