A package includes a container formed to include an interior region and a mouth opening into the interior region and a closure coupled to the container to close the mouth. The closure is made from a film coupled to a brim included in the container.

A sealing film suitable for food packaging is provided, which adopts the following solution. The sealing film comprises, in sequence, a PET layer, a VMPET layer and a PE layer from inside to outside, wherein the PE layer comprises 100-110 parts of PE, 15-20 parts of EVA, 15-20 parts of EAA, 55-60 parts of HDPE and 10-15 parts of LLDPE in parts by mass. In this manner, the addition of HDPE and LLDPE into the PE layer is intended to enhance the tensile strength of the sealing film.

The present disclosure provides a polyolefin-based composition, suitable for use as a tie-layer adhesive composition, and a process for making the polyolefin-based composition. The polyolefin-based composition is made from and/or contains a grafted polyolefin copolymer composition, a base resin composition, and optionally, an additives composition. The grafted polyolefin copolymer composition is made from and/or contains a grafted polyolefin composition, an olefin elastomer composition, and a long-chain branched polyolefin composition. The grafted polyolefin is coupled to the olefin elastomer and the long-chain branched polyolefin.

In a packaging body provided with at least an inner layer composed of a thermal-adhesive polyolefin based resin and a barrier layer composed of a metal foil, in which metal terminals are sealed by the thermal-adhesive resin with unconnected ends of the metal terminals protruding outside, an adhesive sheet for sealing metal terminals of a flat electrochemical cell which is not only able to prevent a short circuit between the barrier layer and the metal terminals but high in a layer-to-layer adhesive strength and a low possibility of a reduction in battery performance to be caused due to invasion of moisture is provided. In the adhesive sheet for sealing a metal terminal part of a flat electrochemical cell according to the invention, a fibrous sheet or a porous sheet is covered by the inner layer and an acid-modified polyolefin based resin layer having adhesive properties.

The present disclosure is directed to peelable, heat-sealable lidding films for containers of diverse polymer compositions storing various products such as foodstuffs and pharmaceuticals. The lidding films disclosed herein can be heat-sealed to crystalline polyester trays (CPET), easily peeled, and contain improved antifogging performance by incorporating a non-migratory antifogging additive into the heat sealable layer of the film without deteriorating seal strengths.

A print and apply system configured to facilitate the application of a flow of activatable labels with variable length to a flow of items, including a roll of activatable label stock with a facestock and an activatable adhesive layer; a software program configured to create a layout for each of the flow of activatable labels with variable length; a printer configured to print on the facestock; a cutter configured to cut off a specific length from the roll of activatable label stock to form the flow of activatable labels according to the layout; an activation unit to activate the adhesive layer to turn it tacky; and, an applicator unit configured to receive and place the labels with activated adhesive onto a flow of items to be labeled. Related methods and uses are described.

Composite film structures for packaging use. The composite film structures have easy open, clean peel and hermetic seal characteristics stemming from good caulkability characteristics when a region of the composite film structures are folded over and sealed to form a seal on a bag, pouch or package. The composite film structure includes a base film which includes a biaxially-oriented film and a vacuum-deposited metal layer and a heat-sealant structure comprising a low density polyethylene and a linear low density polyethylene. The metal layer is between the biaxially-oriented film and the heat-sealant structure. The heat-sealant structure thickness is from about 50 to about 100 gauge, the adhesion strength between the biaxially-oriented film and the metal layer is less than about 800 g/in, and the seal strength when a region of the composite film structure is folded onto a composite film structure region is from about 500 to about 1500 g/in.
