A resealable bag topper for application to a non-resealable packaging bag is disclosed. An example device includes a flexible topper body defining an access channel, a resealable mechanism such as a zipper or slider closure to open and close the channel, and an adhesive portion for affixing the body to the bag. To enable multiple uses of the device, the adhesive portion is specially configured. In one example, the adhesive portion includes a repositionable adhesive or a multi-layer assembly of stacked adhesive layers that enables the entire device to be removed from a first bag and reapplied to a subsequent bag. In another example, the adhesive portion is made integral with the topper body.

The packaging bag comprises a bag body and a U-shaped notch formed in the side portion of the upper portion of the bag body, the left side of the U-shaped notch is a feeding opening of the bag body, the right side of the U-shaped notch is a discharging nozzle of the bag body, the feeding opening can be sealed through a sealing structure, and the discharging nozzle can be sealed through a sealing structure. And a tearable sealing rubber strip is arranged at the top of the bag body. The seasoning box is reasonable in design, simple in structure, convenient to use, good in sealing effect and capable of effectively avoiding the problem of seasoning deterioration.

Packaging comprising a packaging container as well as a multi-layer sealing part, wherein the sealing part has at least one carrier layer and one adhesive layer, the carrier layer consisting of a first polyolefin-based plastic with a first melting temperature, the adhesive layer consisting of a second polyolefin-based elastomer or plastomer with a second melting temperature that is lower than the first melting temperature, wherein the packaging container consists of a third polyolefin-based plastic with a third melting temperature that is higher than the second melting temperature, and has a sealing collar with an essentially planar sealing collar, wherein the adhesive layer of the sealing part adheres to the sealing collar of the packaging container, and wherein the sealing part has an elastic clamping structure in spatial proximity to the sealing collar.

Resealable packaging unit for cigarette papers, including an internal rolling aid, which unfolds automatically when the packaging is opened and folds up automatically when closed, the entire structure is formed by fold lines and adhesive surfaces within a single cardboard blank.

A durable dog chew toy comprising a body made from non-toxic, edible rubber for ergonomic handling and extended chewing is disclosed. The body features sinusoidal grooves on a major surface and uniformly spaced rectangular ridges on at least one side surface, both mimicking a tire tread pattern to enhance grip, stimulate gums, and promote canine dental hygiene. In one embodiment, the chew toy includes a multi-layer construction with a food-grade rubber outer layer, a scented foam middle layer infused with edible flavors, and a solid rubber inner core to resist collapse. The chew toy can be frozen for teething relief. Additionally, the toy can be sold in reusable, resealable packaging made from edible material, enabling safe storage and branding.

The present invention relates to a hot-melt self-adhesive composition comprising:i) from 40% to 80% by weight of at least one but-1-ene-ethylene copolymer A, said copolymer comprising more than 80% by weight of units derived from but-1-ene;ii) from 1.5% to 4.5% by weight of at least one propylene-ethylene-butene copolymer T, said copolymer T comprising more than 50% by weight of units derived from propylene;iii) at least one nonhydrogenated tackifying resin obtained by polymerization, or copolymerization with an aromatic hydrocarbon, of mixtures of unsaturated aliphatic hydrocarbons having from 4 to 6 carbon atoms resulting from petroleum cuts.

This item is a resealable packaging can that can be opened and then resealed.

A package is formed using a laminated structure, and the laminated structure comprises: a first film layer defining a first surface, the first film layer further defining a second surface opposite the first surface, wherein the first film layer includes a laser-distorted uncut region; a second film layer defining a first surface laminated to the second surface of the first film layer and a second surface opposite the first surface of the second film layer, wherein the second film layer includes an internal laser-cut line extending between the first and second surfaces of the second film layer; and a third film layer defining a first surface laminated to the second surface of the second film layer and a second surface opposite the first surface of the third film layer.where the third film layer includes an outer cut line extending between the first and second surfaces of the third film layer, where the inner laser cut line is aligned with the laser-distorted region, and the outer cut line is offset from the inner laser cut line and the laser-distorted region, such that peeling the third film layer at the outer cut line causes the first film layer to break along the laser-distorted region to form a first film layer cut line continuous with the inner laser cut line to allow the first film layer and the second film layer to move together with the third film layer.

Packaging comprising a packaging container and a multilayer closure part, wherein the closure part has at least one carrier layer and an adhesive layer, the carrier layer being a first polyolefin-based plastic with a first melting temperature, the adhesive layer being a second polyolefin-based elastomer or plastomer with a second melting temperature which is lower than the first melting temperature, the packaging container being a third polyolefin-based plastic with a third melting temperature which is higher than the second melting temperature, and a closure collar with a substantially planar closure band, wherein the adhesive layer of the closure part adheres to the closure collar of the packaging container, and wherein the closure part has an elastic clamping structure in spatial proximity to the closure band.

The invention relates to a hot-melt self-adhesive composition comprising: - a mixture S of styrene block copolymers comprising at least one styrene-isoprene-styrene triblock copolymer and at least one styrene-isoprene diblock copolymer, the melt flow index at 200°C and 5 kg of the mixture S being between 3 g / 10 min and 20 g / 10 min, and - at least one tackifying resin, in which the weight ratio of mixture S to tackifying resin is between 67:33 and 77:23. The present invention also relates to a multilayer structure comprising the hot-melt self-adhesive composition according to the invention, to the method for manufacturing same and to the use thereof. In addition, the present invention relates to a resealable packaging.
