Improved polymeric packages with removable non-peelable flange portions of the present invention comprise clamshell packages having a removable and non-peelable package sealing mechanism, which mechanism comprises lines of reduced strength disposed within respective more rigid outside polymeric lid and container layers, which lines of reduced strength do not penetrate the inner disposed less rigid polymeric lid and container layers, whereby the respective lid and container flange portions disposed laterally exterior of the lines of reduced strength can be removed to the package--easily neatly efficiently and without generation of particulate matter.

[ What is claimed is:] [1.] An improved polymeric package with removable non-peelable flange comprising:a laminated package lid formed from a more rigid essentially non-extensible outside polymeric lid layer and a less rigid extensible inside polymeric lid layer;a laminated package container formed

[ What is claimed is:] [1.] An improved polymeric package with removable non-peelable flange comprising:a laminated package lid formed from a more rigid essentially non-extensible outside polymeric lid layer and a less rigid extensible inside polymeric lid layer;a laminated package container formed from a more rigid essentially non-extensible outside polymeric container layer and a less rigid extensible inside polymeric container layer;said laminated package lid and said laminated container respectively including central product enclosing lid and container portions, and peripherally disposed lid and container flanges;said lid and container flanges disposed in abutting sealing relationship;a respective lateral portion of said respective flanges disposed about substantially the entirety of the circumference of said respective flanges to form a sealed package;said more rigid outside polymeric lid layer and said more rigid outside polymeric container layer of said lid and container flanges, including superimposed, parallel lines of reduced strength, spaced from the inside layer, disposed about the circumference of said flanges and interior of said sealed relationship, whereby said respective flanges can be manually gripped and the portion thereof which is exterior of said lines of reduced strength manually removed by fracturing and tearing away said flanges along said lines of reduced strength to open said package.
