摘要:
Sealing product (20), designed to be sealed on at least one ring-shaped sealing zone (4) which surrounds the opening (2) of a container (1), made from a sealing sheet including a support layer (11) made of a fibrous material mainly comprising vegetable fibers and a multi-layer structure (16) including, on one of its faces, an adhesive layer (12) and, on its other face, a sealing layer (15), characterized in that said sealing product is stamped so as to make a relief (24) whose form is such that its base (21) follows, at least discontinuously, a contour close to that of the internal edge of said ring-shaped sealing zone, the structure of the sealing sheet including additionally an intermediate layer (13) made of a plastic having a good strength, able to undergo plastic deformation, and of which the average thickness is such as it endows the entire sealing product with sufficient malleability and resistance for it to be possible to stamp it to the desired shape without tearing.
摘要:
The present invention relates to a banderole (1) having a multilayer structure. The multilayer structure comprises a print layer (3), a first support layer (5), a first adhesive layer (7), a second support layer (9), and a second adhesive layer (11), whereby the first adhesive layer (7) provides a releasable adherence at least on a part of the interfacing area between the first adhesive layer (7) and the second support layer (9). Within the area of releasable adherence a removable portion formed (13, 13') by a part of the print layer (3), the first support layer (5) and the first adhesive layer (7) is defined in size and shape by a continuous tear (15) line that extends through the entire print layer (3), the first support layer (5) and the first adhesive layer (7). The releasable adherence and the continuous tear (15) line facilitate the removal of the removable portion.
摘要:
A multilayer sheet intended for capping off a glass container (10) by heat-sealing it onto the open edge (12) of the container, treated by means of metal oxides and/or metal salts, comprises at least one support layer (21) and one lower layer (22) made of a heat-sealable polymer material onto which an unsaturated carboxylic acid is grafted.
