The invention relates to a packing laminate web with a protective layer which is applied during the manufacture of the laminate web to one, sterile side of the web. When the laminate web is to be converted to aseptic packing containers the protective layer is detached and is transferred to the opposite side of the laminate web where it serves as an external plastic layer. The invention also comprises a method for the manufacture and conversion of the packing laminate web.

Method of making a packing laminate web

Small packing containers such as individual packages for yogurt, ice-cream or the like, are frequently in the form of beakers provided with a lid consisting of a tear-off foil. To reduce the risk of leakage and provide a packing container of greater mechanical strength a beaker type packing container has been provided with an integrated, openable top side otherwise made of the same material as the beaker. The top remains connected to the packing container after it is opened.
