The first and second adhesive layers overlap and are coaligned. The outer and intermediate paper plies and the inner polymer film ply are adjoined to form a multiwall structure, wherein the first adhesive layer and the second adhesive layer are coaligned with each other on the multiwall structure. The first adhesive layer comprises a first plurality of adhesive spots and the second adhesive layer comprises a second plurality of adhesive spots, wherein the adhesive spots of the first plurality of adhesive spots do not overlap with the adhesive spots of the second plurality of adhesive spots.

Thermoplastic films and products with diffusion-based compartmentalized additive components

The present disclosure relates to thermoplastic films and products formed therefrom that include additive components effectively compartmentalized based on diffusion characteristics of the additive components. For example, first and second additive components are localized on a thermoplastic film in a manner that as the additive components diffuse, they minimize or avoid interaction. Specifically, the thermoplastic film is folded over itself to create an air gap that causes the additive components to desorb, diffuse into the air gap, and then absorb into the film at a position across the air gap rather than diffusing substantially laterally across the thermoplastic film. By ensuring that the additive components diffuse up and down rather than laterally and by laterally offsetting the additive components, one or more implementations effectively compartmentalize the antagonistic components.

EASY OPEN PLASTIC BAGS
20240124195 · 2024-04-18 · ·

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 polyethylene layer which can be laminated with a polyethylene 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.

THERMOPLASTIC BAGS WITH DUPLICATIVE SEALS

A thermoplastic bag includes duplicative seals. In particular, in one or more implementations, a thermoplastic bag includes a first seal and at least a second seal reinforcing the same area of the thermoplastic bag. For instance, in one or more implementations, the thermoplastic bag includes multiple seals along each side edge or along the hem. If one seal fails, the other seal(s) can remain in place to prevent leaks. Thus, the duplicative seals of the thermoplastic bag can provide reinforced strength and desired aesthetics.

A remote control packaging (10) made of a folded material of a sheet (1) comprising a closed packaging interior in which a remote control is arranged and a plurality of walls defining the packaging interior, wherein the walls of the remote control packaging (10) are formed in multiple layers with a foil inner layer (8) of poly(1,4-butylene succinate) and a paper outer layer (9) for mechanical stabilisation thereof.

SHEET MATERIAL CONTAINER

The present invention provides a sheet material container (90) being made of a sheet material (20) and including a body portion (12) and a bottom portion (25) that is to be disposed on a placement surface, and the sheet material (20) including a plurality of film layers (20a,20b, and 20c). A body portion sheet (93a) that constitutes the body portion (12) includes a bonding portion (94) where peripheral edge portions of the sheet materials (20) are bonded. In a bottom surface sheet (93b) that constitutes the bottom portion (25), a non-adhesive region (99) is provided in the plurality of film layers (20a, 20b, and 20c). The non-adhesive region (99) forms a bottom filler-filled portion (96b). The bottom filler-filled portion (96b) extends annularly around a non-filled portion (96j), and includes at least three protruding leg portions (96m) that are to be placed on the placement surface so as to allow the container (90) to stand by itself. The protruding leg portions (96m) protrude toward the placement surface past other portions in the bottom filler-filled portion (96b) due a leg forming portion (100)
