A multilayer film that has improved ultrasonic sealing properties is disclosed. The multilayer film includes a first layer and a second layer. The second layer includes a first sublayer composed of a polypropylene copolymer, a thermoplastic polyolefin having a modulus of 1,700 MPa or less, and olefin block copolymer. The second layer further includes a second sublayer composed of a polypropylene homopolymer or polypropylene copolymer. A laminating agent may be positioned between the first layer and the second layer. The multilayer film has a seal initiation temperature of greater than 105 degrees Celsius, in some embodiments, packages made from the multilayer film are adapted to withstand exposure to high heat pasteurization of greater than 70 degrees Celsius.

A paper bag for e-commerce shipments, which paper bag comprises first closure means for first closure of the bag (46, 49, 123, 127a, 127b, 227a, 337, 337a), tear means (47, 126, 136, 226a, 226b, 336) for opening the bag after first closure and second closure means (45, 48, 137, 137a, 238a, 238b, 338, 338a) for reclosing the bag after tearing the tear means. The paper bag is formed of a paper having specific properties concerning—inter alia—the grammage, the tensile index, the bending resistance and the like for rendering the bag especially durable and reliable in use.

The disclosed subject matter provides batter compositions, food package kits comprising batter compositions, and methods of preparing such batter compositions and kits.

An object of the present invention is to provide a pouch and a liquid-containing pouch having high resistance to falling breakage. A pouch (10) is a pouch formed into a bag by an outer peripheral sealing part (20). The pouch includes an accommodating part (30). A fragrance component emission part (40) is formed in the film on at least one side at a position corresponding to the accommodating part. The fragrance component emission part is composed of a material removal part (41) or a score having a notch form, in a range of part of the film in the thickness direction thereof. The tensile strength of the film in a fragrance component emission area in the width direction of the pouch is at least 90 N/50 mm, and the tensile strength thereof in the height direction of the pouch is at least 125 N/50 mm.

A package is provided that is formed from a packaging material, such as film, having increased adhesive in critical locations, such as adjacent folds in the end seal and other areas so that that the increased adhesive can at least partially fill voids adjacent such folds. The additional, localized sealant material is applied in a plurality of discrete locations in the end seal or other region adjacent where folds are formed and overlap with a sealant layer so as to provide additional sealant material for at least partially filling the voids without being present throughout the entirety, majority or large portions of the packaging material.

A flexible laminate, packaging structure and method comprising an outer structure, an inner structure, and a pressure sensitive adhesive layer adhesively joining the outer and inner structures to form a laminate. At least one outer line of weakness is formed in the outer structure, wherein the at least one outer line of weakness terminates in at least one tear receiving element adjacent an opening end of the laminate. A tab is defined by at least one line of weakness formed through both the outer structure and the inner structure, wherein the at least one tab line of weakness terminates in at least one tear propagating element. A second inner line of weakness is formed in the inner structure, wherein the second inner line of weakness is disposed between the at least one tear propagating element of the tab and the at least one tear receiving element of the at least one outer line of weakness.

Paper-based packages and methods of making the same are disclosed. In one example, a semi-rigid package comprises: a base, a first side portion, and a second side portion. The base comprises two opposed major walls and two longitudinal side walls opposed to each other. The first side portion and a second side portion are integrally formed with the base. The two side portions are respectively connected to the base along the longitudinal direction, and each side portion comprises two opposed side panels, two tapered corner portions opposed to each other, and a closure in a transverse direction. Each side panel is connected to the adjacent major wall along a transverse line, and the two opposed side panels are jointed to form the closure. At least one of the side portions may be substantially compacted and form a substantially flat transverse side wall.

A collapsible bag is disclosed having a handle and a compartment attached to the handle, the compartment formed of nine panels comprising front and back trapezoidal panels, a rectangular bottom panel, and left and right triangular expansion zones, each triangular expansion zone formed by an isosceles lower triangular panel and first and second congruent, scalene triangles. The expansion zones occur below a midpoint of the height of the compartment and distributes more space near the bottom of the bag while narrowing the bag at the top of the compartment. Moreover, the distance between the top of the isosceles triangular panels when the bag is open is greater than a width of the rectangular bottom panel and less than the handle width.

A sheet member container having one or more sheet members including a main-body forming sheet member in which a plurality of film layers including an inner film layer and an outer film layer are stacked; a containing portion that accommodates contents; a container main body including the main-body forming sheet member, and surrounding the containing portion; and a peripheral edge sealing portion in which the one or more sheet members are folded along a folding line, and peripheral edge portions of the one or more sheet members are attached to each other.

A container body of the sheet container is composed of a sheet member given by lamination of a plurality of film layers, and has a plurality of surface-like parts; the plurality of surface-like parts include a first surface-like part and a second surface-like part that adjoin and cross each other; the sheet member has a filler enclosing part in which a filler is enclosed between the plurality of film layers; the filler enclosing part includes an intermediate extending part laid across the first surface-like part and the second surface-like part, and a first adjoining part and a second adjoining part that individually adjoin both sides of the intermediate extending part; and the intermediate extending part extending more further from the second surface-like part than the first adjoining part and the second adjoining part extend.
