Multi-layer bag for bulk material, comprising at least one layer of material comprising paper or paper-like material, wherein two layers of material are formed by pieces of tube (22, 32) inserted telescopically in one another, wherein a first of the pieces of tube (22) inserted telescopically in one another has at one end (27) an overhang (U1) with respect to a second of the pieces of tube (32) inserted telescopically in one another.

A bag comprised of paper that is closed, sealed, or resealed for holding food or another object. The bag having an open top, interior and exterior surface. The bag further comprising a closure mechanism.

A biodegradable (repulpable, compostable and/or water soluble) zipper is provided for attachment to a biodegradable flexible package. The biodegradable zipper is formed using a water-soluble polymer that can be combined with a repulpable and/or compostable material, such as a plant-based cellulose material. The biodegradable zipper enables the biodegradable package to be opened and closed by the consumer, so that the consumer has the option to determine, change or manipulate the contents of the biodegradable flexible package.

A repulpable zipper is provided for attachment to a repulpable flexible package. The repulpable zipper is formed using a water-soluble polymer combined with a repulpable material, such as a plant-based cellulose material. The repulpable zipper enables the repulpable package to be opened and closed by the consumer, so that the consumer has the option to determine, change or manipulate the contents of the repulpable flexible package.

An opening device for a package obtained from a sheet of packaging material that comprises at least first and second layers and having a through hole through the first layer and covered by a sheet cover portion of the second layer. The opening device comprises a wall portion applied onto a first side of the sheet cover portion and defining, together with the sheet cover portion, a user-tearable portion of the package; the wall portion comprises a linear weakening slot in a part of the thickness of the wall portion and open at a second surface thereof, opposite the first surface; the linear weakening slot delimits, together with the first side a linear weakening region of the user-tearable portion; the opening device further comprises at least one pull-member to cause tearing of the user-tearable portion along the linear weakening region, and; at least one projecting linear rib element.

Methods of making a protective cover. According to one method, a composite sheet is formed by providing a substrate formed from a nonwoven material having a puncture resistance exceeding 500 N, the substrate having a first surface and a second surface, disposing a first layer of plastic film on the substrate first surface and a second layer of plastic film on the substrate second surface. The composite sheet has a first end, a second end, a first lateral edge, a second lateral edge, and an axis extending between the first lateral edge and the second lateral edge. The method also includes folding the composite sheet about the axis to bring the first end of the composite sheet proximate the second end of the composite sheet and define a partially enclosed space having an opening proximate the first and second ends of the composite sheet.

A plastics shipping bag includes a closure flap which projects beyond the front wall, can be folded over the outer face of the front wall, and comprises a passage opening, which is configured and designed for the passage of a handle loop or handle of the front wall and/or rear wall, wherein the closure flap comprises at least one fastening means between the opening edge of the rear wall and the passage opening, which fastening means is configured and designed to close the opening end once the closure flap has been folded over onto the outer face of the front wall. The plastics shipping bag can be used for shipping foods, such as chilled foods.

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.

A woven laminated plastic bag having an easy open feature is provided. The easy open feature is generally defined by a weakened portion in the bag. In various aspects the bag can be fabricated from a woven polypropylene and/or polyethylene layer which can be laminated with a film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing.
