Reclosable packing system

摘要

The invention concerns flexible, composite, multilayer sheets which act as means to open and close appropriately shaped containers (f.i. trays) of products consumable also in more successive doses and which are characterized by an opening edge, a device to stop said opening, a tamper evident device and a protection layer. Said multilayer sheets include at least: a first superior outer layer consisting of at least a film acting as support of the printing and of a press-sensitive adhesive; a second inferior inner layer consisting of at least a thermosealant film and characterized by die-cut zones having the function to detemine the access mouth shape and to create an invitation to the eased opening; and an intermediate layer consisting of a press-sensitive adhesive.
