Disclosed is a flexible packaging container, in particular a plastic film pouch or bag for bulk goods, comprising a front wall (2) and a rear wall (3) as well as a holding space (15) between said walls (2, 3) for goods to be stored; the walls (2, 3) are made at least in part of a film material; the flexible packaging container further comprising an intermediate space (14) which is formed by an inner ply (4) and is separated from the holding space (15) by said inner ply (4); the holding space (15) can be evacuated into the intermediate space (14) via at least one holding space evacuation hole (7) in the inner ply (4), and the intermediate space (14) can be evacuated out of the packaging container (1) via at least one additional evacuation hole (11) that interrupts a transverse seam; the front wall (2) does not comprise any of the longitudinal seam (12) that seals the packaging container (1) in the peripheral direction; the inner ply (4) is formed by a strip (4) which is located on a side of the front wall (2) facing the intermediate space (14) and which is fastened to the front wall (2) using two longitudinal seams extending between top and bottom transverse seams (5.1, 5.2).

A vacuum bag is disclosed. The vacuum bag may include a body. The body may include a plastic layer and a fabric layer. The plastic layer and the fabric layer may be welded together on at least one portion of the body. The vacuum bag may further include a seal bar and a valve.

The present utility model refers to a bag or a bundle-type packaging suitable to contain cement or other similar material, consisting of at least one sheet of paper wherein the external sides of said sheets are coated with at least one layer of hydrophobic paint.

This paint transfers water-repellent characteristics to the paper; in this way, both the transmission of moisture/water vapor (WVTR) and the absorption of water (COBB) are significantly reduced.

In fact, thanks to at least one layer of paint applied externally to the sheets of paper that make up the bag, the water is not retained by the paper, but slips away due to the high surface tension present on the treated paper.

The barrier effect is thus increased compared to that obtainable from standard bags known in the art, thus guaranteeing the product contained inside the bag a high protection from humidity, even in the absence of intermediate polythene sheets in the manufacture of the bag and, consequently, improving the shelf life of the product contained inside the bag.

The bag achieves these results even though it has no intermediate plastic layers.

A package has a first side coupled to a second side to form a space for storing material therebetween, the space having a re-sealable proximal end and a distal end. The first side has a plurality of layers, the plurality of layers selected from the group consisting of selected from the group consisting of OPP (oriented polypropylene film), KRAFT paper, VMPET (vacuum metallized polyester film), PE (polyethylene plastic), and PET (polyethylene terephthalate). The re-sealable proximal end has a tear strip and a zipper engagement, the zipper engagement distal of the tear strip. The tear strip is configured to be torn off to expose the zipper engagement. The zipper engagement is re-sealable.

One or more implementations of a multi-layer film include a first layer non-continuously bonded to a second pigmented layer. The multi-layer film includes an unexpected appearance differing from the appearance of the pigmented layer. In one or more embodiments, the multi-layer film includes a metallic appearance despite the pigmented layer being devoid of metallic pigment. The multi-layer film also includes areas that are visually distinct from areas of the film with the unexpected appearance. The visually-distinct areas comprise areas in which the first layer non-continuously is in intimate contact with the second pigmented layer. The visually-distinct areas have the appearance of the pigmented layer or another appearance. One or more implementations also include methods of making multi-layer films and bags with an unexpected appearance and visually-distinct areas.

A bag is provided having a first end and a second end. The bag has a generally tubular shape, with the first end configured to remain sealed and the second end configured to be opened. The second end defines a recess, and the bag is configured to receive one or more objects in the recess defined within the second end. The bag has a first cross section at a location between the first end and the second end. The bag is folded in the first cross-section so that the bag material forms at least three plies. At least one inner ply is formed, at least two outer plies are formed, and a first portion of the at least one inner plies is left exposed. One or more bags may be provided as a sheet. Methods for making the bags and for opening the bags are also provided.

Described are various embodiments of a flexible container, envelope or enclosure having one or more sealable side pouches for maintaining therein a material capable of transferring or extracting heat to or from a sealable inner compartment. The flexible container, envelope or enclosure is generally formed by layering and folding an inner thermally-conductive material sheet and substantially non-thermally-conductive outer sheet of material and sealing about the open edges thereof so as to form distinct compartments of the side pouches, and the inner compartment. Each of the side pouches and inner compartment may be reversibly sealable. In some embodiments the outer sheet is a made from a reflective insulated metalized polymeric bubble sheet.

This invention relates to a protective article comprising first and second walls. Each of the walls includes superimposed plies enclosing an expansion space therebetween, and an expandable composite disposed in the expansion space. The expandable composite includes an emulsion polyolefin dispersion and a plurality of expandable microspheres. The expandable microspheres are configured to cause the emulsion polyolefin dispersion to expand upon activation of the expandable microspheres. The invention further relates to an expandable web comprising a first ply, second ply and an expandable composite deposited between the first ply and the second ply. The invention further relates to a method for making an expandable protective article.

A child-resistant resealable container comprising a closure strip assembly having first and second lateral interlocking members. The first lateral interlocking member is attached to a first extension strip, and the second lateral interlocking member is attached to a second extension strip. The first and second extension strips are attached to the interior surfaces of the respective first and second walls below the top edge of the first and second walls such that a portion of the first and second walls extends to define first and second flaps. The first and second lateral interlocking members are configured to become disengaged from each other when the first flap and the second flap are pulled apart from each other as the first flap is gripped while the first extension strip is not gripped and the second flap is gripped while the second extension strip is not gripped.

The present invention is directed to a bag of polymeric film and a method to make the bag. The bag can be comprised of a front panel and a rear panel. The front and rear panels can each be comprised of multiple layers of film. The bag can be formed from a collapsed bubble of polymeric film that has been folded in half so that opposing edges of the collapsed bubble form an opening of the bag. One of the layers of the folded bubble can be split adjacent to an edge of the collapsed bubble and a draw tape film can be inserted between the layers of the folded and collapsed bubble. The collapsed bubble can further be embossed by a pattern that can provide enhanced properties to bags formed from the folded bubble.
