Abstract
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.
Claims14
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.
A process for the preparation of a packaging structure for biomedical films, comprising assembling 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.
A packaging structure for biomedical films comprising the following overlapped layers, in the following order:
- (A) a laminate;
- (B) a supporting layer;
- (B′) a supporting layer;
- (A′) a laminate;
- wherein:
- the laminates (A) and (A′) are able to adhere to each other at room temperature and reversibly,
- the supporting layers are smaller in area than the 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.
Use of a packaging structure for the packaging of biomedical films, the packaging structure comprising the following overlapped layers, in the following order:
- (A) a laminate;
- (B) a supporting layer;
- (B′) a supporting layer;
- (A′) a laminate;
- wherein:
- the laminates (A) and (A′) are able to adhere to each other at room temperature and reversibly,
- the supporting layers are smaller in area than the 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.
