Abstract
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.
