Abstract
The invention is directed to a packaging film (2) comprising: a top layer (4) with at least one aperture (4.1); a bottom layer (8) adhered to the top layer (4); a tear layer (6) adhered to the bottom layer (8) and extending along the at least one aperture (4.1) so that upon traction on the tear layer, said layer tears the bottom layer (8) through the aperture(s) (4.1). The tear layer (6) extends beyond the at least one aperture (4.1), between the top layer (4) and the bottom layer (8), preferably longitudinally in two opposite directions. The invention also relates to a condom wrapping with such a film and to the manufacturing method for such a film.
Claims20
Packaging film comprising:
- a top layer with at least one aperture;
- a bottom layer adhered to the top layer;
- a tear layer adhered to the bottom layer and extending along the at least one aperture so that upon traction on the tear layer said layer tears the bottom layer through the at least one aperture;
- wherein the tear layer extends beyond the at least one aperture, between the top layer and the bottom layer longitudinally in two opposite directions;
- and
- wherein the tear layer comprises a pull tab which is unitary with the tear layer and formed by a portion of said tear layer that is folded on itself.
A condom wrapping comprising two superimposed sections of packaging film joined at the edges to form a container housing a condom in a rolled-up state with a condom vessel in a normal position adjacent to one of the two sections of film, the normal direction of unrolling the condom being towards the other section of film, wherein the section of film adjacent to the vessel is a film comprising:
- a top layer with at least one aperture;
- a bottom layer adhered to the top layer;
- a tear layer adhered to the bottom layer and extending along the at least one aperture so that upon traction on the tear layer said layer tears the bottom layer through the at least one aperture;
- wherein the tear layer extends beyond the at least one aperture, between the top layer and the bottom layer longitudinally in two opposite directions.
A method for manufacturing a packaging film comprising:
- a top layer with apertures;
- a bottom layer adhered to the top layer;
- a tear layer adhered to the bottom layer and extending along the apertures so that upon traction on the tear layer said layer tears the bottom layer through the apertures;
- wherein the tear layer extends beyond the apertures, between the top layer and the bottom layer longitudinally in two opposite directions;
- wherein the tear layer comprises pull tabs which are unitary with the tear layer and formed by a portion of said tear layer that is folded on itself;
- the method comprising the following steps:
- (a) forming the pull tabs unitary with a strip of the tear layer by folding on itself and adhering portions of said strip at regular intervals;
- (b) inserting the strip of tear layer with the pull tabs between the top layer and the lower layer by bringing into register the pull tabs and the apertures, and adhering portions of said strip to said lower layer.
