A laminated stretched polyamide film in which an easily adhesive layer (layer B) is laminated on at least one surface of a base layer (layer A), wherein the layer A contains not less than 70% by mass of polyamide 6, and the layer B contains 0 to 40% by mass of polyamide 6 and 60 to 100% by mass of a polyamide 6 copolymer in which a ratio of a copolymerization component in the copolymer is 3 to 35% by mass.

An absorbent paper laminate, having an absorbent paper layer, a nonabsorbent high-density paper layer and an adhesive applied in a layer between the absorbent and nonabsorbent layers forming a laminate. The laminate has a surface which is provided with an array of perforations formed by needle punctures, or a series of slits sized to allow steam to pass therethrough while retaining grease and oil in the absorbent paper layer. The preferred adhesive layer is selectively in a cellular pattern. A paper board food container can be formed having an absorbent paper laminate body defining a cavity for receiving a food item and absorb grease and oil. Optionally an exterior surface of the container is sized to be held in the hands of a user having an exterior surface with a second absorbent layer that can act as a napkin absorbing grease and oil from the hands of the user.

A recyclable, laminated polyolefin-based film structure comprises two or more film plies laminated to each other. Each of the laminated film plies comprises one or more polyolefin-based films. The film structure has an energy-cured coating layer disposed on the outermost outward facing surface of the film structure and a printed ink layer on an interior surface of one of the polyolefin-based polyolefin layers. In certain embodiments, the outermost surface of the laminated polyolefin-based film structure has a melting temperature which is at least 100 degrees Celsius, and more preferably 180 degrees Celsius, higher than a melting temperature of the innermost surface of the laminated polyolefin-based film structure.

A solvent-based polyurethane retort adhesive composition for producing laminates including: (A) at least one isocyanate compound, Component A; and (B) at least one isocyanate (NCO)-reactive component, Component B, comprising (i) at least one phosphate ester compound and (ii) at least one polyester polyol having an average molecular weight of greater than 3,000 g/mol; a process for producing the above adhesive; a multi-layer laminate product including the above adhesive; and a process for producing a laminate product using the above adhesive.

Multilayer film embodiments are directed to films produced via thermal lamination without adhesive due to the use of tie layers comprising a blend of ethylene acrylate copolymer and an anhydride grafted ethylene α-olefin copolymer

The invention provides a polyolefin-based resin film including a polyolefin-based resin composition that includes at least a propylene-α olefin random copolymer, wherein (1) an olefin-based block copolymer is 0 to 2 parts by weight based on 100 parts by weight of the propylene-α olefin random copolymer; (2) an olefin-based copolymeric elastomer resin is 0 to 2 parts by weight based on 100 parts by weight of the propylene-α olefin random copolymer; (3) a propylene homopolymer is 0 to 40 parts by weight based on 100 parts by weight of the propylene-α olefin random copolymer; (4) the polyolefin-based resin film exhibits a thermal shrinkage rate of 25% or less in a direction in which the thermal shrinkage rate is larger between a longitudinal direction and a lateral direction; and (5) a planar orientation coefficient ΔP calculated from a refractive index of the polyolefin-based resin film is 0.0100-0.0145.

To reduce the amount of staining that occurs during the in-package retort processing of food products, a packaging film is used including a white multilayer film, the white multilayer film having a sealing region on the exposed surface of the packaging film, a white region containing white pigment and a blocking region located between the white region and the sealing region, where the combined thickness of the sealing region and the blocking region is at least 70% of the thickness of the white multilayer film.

A laminate tube container is made of laminate film or sheet comprising of a vapor metalizing polyethylene film with a vapor evaporated side made of a metal, metal-oxide or inorganic substance, which is adhesive-laminated on the evaporate side with polyethylene film and an adhesive agent then laminated with other extrusion layers of polyethylene, tie and copolymer of ethylene and vinyl alcohol. The laminated tube giving both oxygen and water vapor barrier characteristics making them suitable for packaging tube particularly filled with contents, such as liquid or creamy cosmetic products and toothpastes.

Provided is a synthetic resin container that includes a container main body molded into a predetermined container shape and a covering layer laminated on an outer peripheral surface side of the container main body. A label is mounted on a container body portion. The container main body is provided with a step portion formed by raising or denting a peripheral surface that extends continuously or discontinuously along a predetermined direction and the covering layer is provided with, continuously or discontinuously along the step portion, a linear thin portion that is linearly thinner than a surrounding area. At least part of the label is adhered to a portion of the covering layer adjacent to the linear thin portion.

A container for stacked food products, such as potato chips, is provided. The container includes composite laminate that includes one or more layers of cardboard. The container has a non-circular shape. The container has a horizontal cross-section with end portions that have a constant radius along their length and side portions that have a changing radius along their length wherein the end portions and the side portions transition between each other continuously.
