Systems and methods of a container having a tack welded fin seal. The container may include a film, a tack weld joining a first outer portion of a first edge and a second outer portion of the first edge, and a fin seal joining a first inner portion of the first edge of the film and a second inner portion of a second edge of the film. The container may include a faceplate integrally molded to an outer layer of a first end portion of the film. The faceplate may include substantially the same composition as an outer layer of the first end portion, such that no distinct layers are formed between the faceplate and the film. The tack weld may be formed at a tack welding system, and the fin seal may be formed at a fin sealing system having a mandrel.

A package designed to prevent the leakage of its contents and to capture any leaked contents within a package reservoir, while permitting the package to be sealed for later access to the contents of the package.

An absorbent-article container includes a containing member; and an absorbent article contained in the containing member. At least a part of an outermost surface of the containing member is formed of paper. At least a part of an outermost surface of the absorbent article is formed of nonwoven fabric. A minimum value of a dynamic friction coefficient on an innermost surface of the containing member is less than a dynamic friction coefficient on the part of the outermost surface of the containing member.

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.

To provide a container bag 34 that can be manufactured easily by folding a sheet material 1 precisely along a folding line 11B. The sheet material 1 is prepared by bonding two films 2 and 3 together in a predetermined pattern, and the sheet material 1 comprises a plurality of cells 16 formed between the two films 2 and 3 while being joined to one another to be filled with fluid. A trunk portion 17 to be filled with a content is formed by bonding overlapping layers of a peripheral edge 9A of the folded sheet material 1. A bottom portion 13 of the container bag 34 is folded inwardly toward the trunk portion 17 along the folding line 11B. A non-bonded section 14 in which the two films 2 and 3 are not bonded together is maintained linearly within the folding line 11B.

A flat-bottomed bag is formed from a flexible sheet that initially is flat prior to being manipulated to form the bag. The sheet is a laminate of a first web and a second web laminated together by an adhesive layer disposed between the webs. The sheet defines a plurality of serially connected side wall panels collectively defining a vertically extending side wall of the bag, and a plurality of bottom panels respectively connected to the side wall panels at respective fold lines. The bottom panels are folded about the fold lines and are attached together to form a flat bottom wall configured to support the bag in an upright orientation. The adhesive layer is in a partial-coverage pattern that includes adhesive-free regions located along each fold line between each bottom panel and the respective side wall panel connected therewith.

Flexible containers are provided herein. In some embodiments, the flexible containers include a front panel, a back panel, a bottom panel, and a top panel attached to form a pourable material storage area, wherein the front panel and the top panel include a hole in the front panel and the top panel to form a dispensing system passage, and wherein the dispensing system passage is not in fluid communication with the pourable material storage area. A dispensing system is attached to the top panel between the top panel and the back panel and extends through the dispensing system passage.

A container and method of manufacture of a container made of a single material is provided. The container includes a base having a base perimeter with a surface, and a wall having an upper edge and a lower edge, the upper edge comprising two upper edge portions, wherein the lower edge is affixed about the entire perimeter surface, and the first upper edge portion is affixed to the second upper edge portion, thereby forming a space to hold foodstuffs. The base stock material is cut and formed into a base with the base perimeter. A seal is applied between the lower edge of the wall and the surface of the base perimeter. Another seal is applied to two vertical end portions of the wall, forming a cup-like container with an internal space. A final seal is applied between two portions of the upper edge of the wall completing the container.

The present invention provides a pouch having a liquid accommodation space for storing a liquid material therein, and in the pouch, boundaries of a first sheet material and a second sheet material are bonded to each other to form an upper fusion portion, a lower fusion portion, a first side fusion portion, and a second side fusion portion. In the liquid accommodation space, a dividing fusion portion is formed apart from the first side fusion portion, and a drink suction tunnel is formed between the dividing fusion portion and the first side fusion portion. The drink suction tunnel includes first and second curved portions which are formed by making the first sheet material and the second sheet material protrude outward between the first side fusion portion and the dividing fusion portion, wherein the first and second curved portions are formed by a thermoforming.

A packaging body configured with a packaging film, in which the outermost layer is a polyethylene-based resin layer and the polyethylene-based resin layer is uniaxially or biaxially stretched.
