Embodiment Construction

[0046] figure 1 and 2 A first embodiment of the packaging film of the present invention is shown.

[0047] figure 1 An exploded view of the components of the packaging film according to the first embodiment is shown. The packaging film 2 is made of multiple layers. The packaging film 2 comprises a top layer 4 with holes 4.1. The top layer 4 is continuous and preferably non-tearable. It can be die cut by mechanical or laser technology.

[0048] Directly below the top layer 4, a tear-away layer 6 is provided. It consists in this example of a strip comprising a series of pull tabs 6.1 and an elongated portion 6.2 adhered to the bottom layer 8 . Each tab 6.1 forms a hinge 6.3 with a part 6.2. Each portion 6.2 is also transversely weakened 6.4 in order to allow separation of the straps when traction is exerted on the corresponding tab 6.1. Each tab 6.1 may be formed by folding a part of the strip on itself, the free end 6.5 of said tab 6.1 corresponding to the fold of sa...

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 bottomlayer (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.

Description

technical field [0001] The invention relates to the field of packaging films, in particular packaging films with predetermined opening tracks. Background technique [0002] Published prior art patent document US 2,991,000 discloses a membrane according to the preamble of claim 1 . The film is used to form bags or pouches. The membrane is made of a first layer (12) comprising openings (22). On the inner side of the opening (22), the layer (12) is provided with an unsupported strip (24) to cover said opening. A tear seal (18) is applied on the outside of the opening (22) and adhered to the unsupported strip (24). The tear seal is made of layers and flaps that can be grasped by the user's fingers. To open the bag, the user grasps the tear seal (18) and pulls it out. The unsupported strip (24) is torn off, thereby opening the bag. Such a membrane allows quick opening of the bag. The film is very beneficial in terms of the manufacturing process as it can be made from a lam...
