Abstract:
A new process is described for the production of polylaminate film (F) for packaging and the reel obtained, comprising the phases of unwinding (1) of an inner film (N) and an outer film (E), application (3) of adhesive substance (C) on the bonding surface of said inner film (N) and/or of said outer film (E), with the exception of localised areas (N1, E1); bonding (5) of said outer film (E) with said inner film (N) so that the respective said localised areas (E1, N1) are opposite each other, creation (6, 7) of one or more holes (N2, E2) on said inner film (N) and on said outer film (E), in each of said localised areas (N1, E1) and wherein said holes (N2) of said inner film (N) do not overlap said holes (E2) of said outer film (E); rewinding (8) of said polylaminate composite film (F) on a reel.
Abstract:
The invention relates to a plastic bag (10), made from plastic film (20) with one or more ports (30). At least one of said ports (30) comprises a plastic element (40), welded between two layers of plastic film (22, 24), thus forming a port welded region (50). The plastic element (40) in the port welded region (50) may be compressed. The cross-section of the free, uncompressed plastic element (40) runs in the form of a wedge to the lateral edges of the port welded region (50). The plastic element (40) comprises at least one first edge (80) in the port welded region (50). The plastic bag (10) permits an optimised production method and is particularly suitable for application in the medical field.
Abstract:
This invention relates to a method of forming a bag. The method includes the step of forming a line of weakness in a portion of material being used to form a part of the bag, placing a patch over the line of weakness, and forming the bag. The arrangement and construction is preferably such that the patch is located substantially inside the bag thus formed. The line of weakness and patch may preferably act as a self-closing opening for the bag. A bag which includes such a self-closing opening, and bag machinery used for forming such a bag, are also described.
Abstract:
The invention concerns a package comprising at least two sheets (2, 3) and two flexible films (10a, 10b) arranged between them and welded to the sheets (2, 3) by weld seams (11a, 11b) respectively, and welded together and to the sheets (2, 3) by weld seams (12a, 12b), at least one of the two films being folded on the other at the end of the films, opposite the weld seams (11a, 11b). The invention also concerns a method for making such a package. The invention enables to obtain a package with simplified structure and production.
Abstract:
The invention relates to a method for producing stable tubular pouches that are formed integrally from a two-dimensional material (22) without pre-cutting. Said pouches are provided with a re-closable element (3), a pouring spout (4) with head seams (6) and a closing seam (5), a folded-in bottom and a folded-in head part (17). The invention also relates to a bag forming, filling, and sealing machine for carrying out said method. According to the method for producing tubular pouches, the tube is produced from a two-dimensional material (22) by means of a shaping shoulder (28) and a shaping collar (29) that surrounds a filling tube (23). The two marginal areas of the two-dimensional continuous material are contacted with each other so that they widely overlap in the perpendicular direction. Said wide overlap extends laterally of the filling tube (23) and transversally to the direction of advance of the two-dimensional material and is displaced in parallel to the filling tube (23). The pouring spout (4) is formed by punching the wide and two-dimensional overlap to give a pouring spout and at the same time undetachably closing the marginal areas of the pouring spout thus formed with head seams (6) and a closing seam (5) as the outer delimitations of the pouring spout.
Abstract:
A dispensing package (1) for fluid products and the like comprises a container (2) shaped to receive and retain a fluid product therein, and includes a discharge aperture (4) therethrough. A self-sealing closure (5) includes a marginal flange portion (6), and a head portion (7) with an orifice (8) which opens and closes in response to the application of a predetermined discharge pressure. The flange portion of the closure is positioned about and encloses the discharge aperture, and is constructed from a thermoplastic material, which is heat fused to the container to form a secure interconnection and fluid seal therebetween.
Abstract:
A method and apparatus for attaching a spout to a planar portion of an article such as a milk or juice carton (2), which may be integrated into conventional carton forming and filling machines, includes the steps of heating a stem (4) of a spout, applying a bonding agent to a flange on the spout, positioning the spout in a predetermined relation to a spout applicator (200), positioning a carton (2) with a hole provided in a predetermined relation to the spout applicator (200) and attaching the spout to the carton where the heated stem is deformed to mechanically engage the carton about the hole. An apparatus to accomplish the method is also disclosed.
