发明名称 Easy opening plastic package.
摘要 An easy opening plastic package (10) which comprises a flanged container formed from a laminate which has at least two layers (14) bonded together by a relatively weak adhesive (20) which allows the layers to be easily pulled apart and wherein the container flange (12) is formed with a crimp (22) which is thin enough to weaken the flange sufficiently so that it breaks away easily when the two layers are peeled apart. Finally, the package includes a lid (24) which is strongly attached to the container flange.
