A multilayer container for dispensing product that includes a relatively rigid outer body and a relatively flexible inner liner for holding product to be dispensed. The relatively rigid outer body includes, and preferably consists essentially of, an outer layer of virgin polyethylene such as HDPE, and an inner thicker layer that includes polyethylene regrind. The relatively flexible inner liner includes, and preferably consists essentially of, an outer delamination layer adjacent to the inner layer of the body and composed of nylon, nylon blends or EVOH, an inner layer of polyethylene such as LLDPE, and an adhesive securing the inner and outer layers of the liner. The relatively thin outer HDPE layer on the plastic body provides desired appearance, while the thicker inner layer provides structural rigidity using reground plastics. The nylon, nylon blend or EVOH outer liner layer provides improved barrier properties against migration of water, gases and flavorants, while the inner layer of LLDPE provides primarily enhanced flexibility and freedom from cracking, as well as additional barrier moisture qualities.
A multilayer container for dispensing product which comprises:
The container set forth in claim 8 wherein said outer layer of said body is not more than 0.004 inches thick, and said inner layer of said body is in the range of 0.010 to 0.020 inches thick.
