A container constructed from a laminate structure (30) which includes a layer of foamed polymer (34). The layer of foamed polymer (34) replaces the paperboard layer of known laminate structures. A preferred embodiment of the laminate structure (30) is comprised of a layer of foamed polymer (34), a first layer of low density polyethylene (32), a second layer of low density polyethylene (36), a layer of aluminum foil (38), a tie layer (40), and a third layer of low density polyethylene (42). The layer of foamed polymer may be comprised of polyethylene terephthalate, polypropylene, high density polyethylene, low density polyethylene, compositions comprising any of these polymers, or any other suitable foamed polymer compositions that possess similar physical characteristics. The first layer of low density polyethylene (32) coats the outer surface of the layer of foamed polymer (34), and the second layer of low density polyethylene (36) coats the inner surface of the layer of foamed polymer (34). The layer of aluminum foil (38) is applied on the inner surface of the second layer of low density polyethylene (36). The inner surface of the layer of aluminum foil (38) is coated with the tie layer (40). The product-contact surface is the third layer of low density polyethylene (42), and it is coated on the inner surface of the tie layer (40). The container has a non-polar homogeneous heat seal which may be created by conventional equipment ranging from about 250 degrees Fahrenheit to about 500 degrees Fahrenheit.
