Abstract: A lightweight plastic container is provided which has stress crack resistance and comprises at least one layer comprising post consumer plastic film resin; a fusion blend of post consumer plastic film resin and post consumer plastic milk resin; or a fusion blend of post consumer plastic film resin, post consumer plastic milk resin and virgin high density ethylene copolymer plastic material. The container may be a single layer container or a multilayer container.

Abstract: A plastic container made from a fusion blend of a post consumer plastic and ethylene polymers and comprising post consumer resin of homopolymer high density polyethylene resin and a small amount of linear low density polyethylene resin. In another form, the container is made from a blend of post consumer homopolymer high density polyethylene resin, virgin high density polyethylene resin with a small amount of linear low density polyethylene resin. The physical properties of the container including stress crack resistance are maintained as contrasted to the loss of such physical properties that have been heretofore resulted from the use of post consumer resins.

Abstract: A plastic container made from a fusion blend of a post consumer resin and a high density polyethylene copolymer resin. The post consumer resin is primarily a high density homopolymer and may contain small amounts of colored plastic containers and propylene resin. The physical properties of the container including stress crack resistance are maintained as contrasted to the loss of such physical properties that have been heretofore resulted from the use of post consumer resins.

Abstract: Method and apparatus are provided for producing a stress-strain type curve for evaluating the functionality of a thermoplastic bottle. The method generally comprises the steps of internally pressurizing a thermoplastic bottle with an incompressible fluid by relative movement of a piston and a cylinder, sensing the pressure of said fluid and sensing the relative movement of said piston and cylinder as said bottle is being pressurized by such movement, and graphically and automatically recording said sensed pressure and said sensed relative movement as said bottle is being pressurized. The technique is rapidly performed with high sensitivity and automatically produces a curve in which one axis is pressure related and another axis is relatable to the deformation of the bottle.
