The first polymeric panel may consist of such compounds as polyethylene, polypropylene, copolymers of polyethylene and polypropylene, and physical mixtures thereof. The second polymeric panel may consist of such compounds as polyethylene, polypropylene and mixtures thereof, polyester, and polystyren
The first polymeric panel may consist of such compounds as polyethylene, polypropylene, copolymers of polyethylene and polypropylene, and physical mixtures thereof. The second polymeric panel may consist of such compounds as polyethylene, polypropylene and mixtures thereof, polyester, and polystyrene. An appropriate adhesive is utilized to seal the two panels depending on the composition of the second panel.
