Abstract
Rigid wadding, insulation and packaging for food and other products is made of homogeneous polyester terephthalate (PET) that satisfies the resin recycling identification code number one. For purposes of protecting an inner rigid wadding or other insulation, one or more film strips or film coatings may be applied by the artful use of amorphous (non-crystalized) PET that melts at a lower temperature and can act as a thermal bond adhesive. The film strips or film coatings may be made of homogeneous polyester terephthalate (PET) that satisfies the resin recycling identification code number one.
