PACKAGING STRUCTURE FOR BIOMEDICAL FILMS

摘要

A multilayer structure for the packaging of biomedical films, in particular oral films, is described, said multilayer structure comprising cold-adhesive laminates and at least partly non-adhesive supporting layers which are organized in a specific stratified structure. The film packaged therein is effectively isolated from the external environment and protected from accidental mechanical stresses; the packaging process is low-cost and particularly attentive to the delicate structural characteristics of biomedical films.

1. A packaging structure of biomedical films comprising the following overlapped layers, in the following order:
(A) a laminate; (B) a supporting layer; (C) a biomedical film; (B′) a supporting layer; (A′) a laminate; wherein: the laminates (A) and (A′) reversibly adhere to each other at room temperature the said supporting layers are smaller in area than the said laminates and are positioned fully within the laminate area, thereby determining a perimetral band P in which the internal faces of the laminates (A) and (A′) are in reversible adhesive contact with each other.
