Abstract: A packaging material is formed of a composite film obtained by bonding a first film formed of a resin film and a second film having a stretch ratio lower than a stretch ratio of the resin film forming the first film or formed of a non-oriented resin film. The first film has a linear cut, a predetermined length in the longitudinal direction of the cut, and a predetermined width in a direction perpendicular to the cut. The packaging material includes a first strongly bonded section in which the first film and the second film are firmly bonded and a first weakly bonded section and a second weakly bonded section provided at both sides of the first strongly bonded section, with the first film and the second film being weakly bonded in the first weakly bonded section and the second weakly bonded section.

Abstract: The purpose of the present invention is to provide: a packaging container that can be industrially mass-produced, that can be used as Modified Atmosphere Packaging (MAP) while ensuring sealing performance, and that allows contents to be displayed in a three-dimensional manner; a packaged product contained in the packaging container; and a manufacturing method and manufacturing apparatus for the packaging container. This packaging container has: a container main body having a bottom face part and sidewall parts, and having a flange at the upper end part periphery of the sidewall parts; and a lid material heat-sealed to the flange. The lid material is made of a film or sheet. A pair of opposing sidewall parts has the same shape, and upper end parts of the pair of side wall parts are at least positioned higher than the upper end parts of another pair of opposing sidewall parts.

Abstract: A pleated stand-up packaging pouch has a rib in a pinch form which is formed by adhering inner faces of end edges of the packaging material and at least one pleat which is formed by folding the pleated stand-up packaging material in a three-ply strip form in the orthogonal direction to its longitudinal direction and adhering inner faces of the folded portions, and is characterized in that the pleat formed on an edge between a folded bottom face portion and a peripheral portion extends from the peripheral portion in the same plane as the peripheral portion, and the bottom face portion and an upper end of an underside face of the pleat form a substantially right angle, and the pleat has a cut-off portion at the portion where the pleat and the rib cross.

Abstract: The present invention provides a closure having a closing function and reclosability that is gentle on the hands of consumers and can have a low environmental impact. The invention also provides a closure whereby the connection parts in a band of connected closures are resistant to the influences of humidity changes. The present invention is a closure having a closing function and reclosability, formed of a composite layer having a layer made of paper, and provided with a closure hole, provided in substantially a center, for closing an object to be closed, as well as an opening that is smaller than the closure hole provided at one end, the opening communicating with the closure hole. Preferably this closure comprises a synthetic resin layer laminated between two layers of paper.

Abstract: The object of the present invention is to provide a pleated stand-up packaging material which is capable of improving a heat seal property on a portion where a rib and a pleat cross at a right angle. Another object of the present invention is to provide a pleated stand-up packaging material which is capable of improving a stability and an esthetic appearance when it is stood up by sharply bending the portion where the rib and the pleat cross at a right angle.

Abstract: A stand-up packaging pouch manufactured in three-dimensional form or flattened form and provided with at least front face portion and rear face portion sides formed from packaging material having a pleat which is formed by folding a part of the packaging material in a three-fold strip form and adhering the inner faces of this folded part is constituted such that when the pouch is opened out into three dimensions, the pleat, formed in the same plane as the peripheral face portion, is positioned at a substantial right angle to a bottom face portion, thereby concealing the bottom face portion.

Abstract: A packaging material is provided that can provide a packaging bag or container cover in which the contents is shielded from the atmosphere and tightly sealed, a small hole is formed in the appropriate locations, without special processing of the heat seal portion, and the internal pressure is maintained with high stability at a level above the normal pressure. The packaging material is suitable, for example, for heating in a microwave oven. The packaging material uses a film in which a heat sealing agent (4) with a low melting point is applied to a prescribed zone of an oriented film (2) made of a synthetic resin, a cutting line (5) is cut in the oriented film (2) made of a synthetic resin in the form of a solid or broken line passing through the zone coated with the heat sealing agent (4), and a cast film (3) made of a synthetic resin and having heat sealing properties is affixed to the oriented film (2) made of a synthetic resin. Such film is used for a packaging bag (1) or a container cover.

Abstract: An adhesive sheet capable of repeated adhesion and release is provided. A non-adhesive protective material 3 layer is provided to the surface of a substrate 1 coated with an adhesive agent 2 so that the spaces obtained by multiplying the surface area of adhesive sections by the thickness (distance) of the protective material is adjusted so that the adhesive sheet will be capable of repeated adhesion and release.

Abstract: A zipper for closing the mouth of a bag that is formed by a groove on an internal face of tape, on one side, and a rib to be fitted to the groove on another internal face of the tape, on the other side. A bonding agent layer is provided on the outer side of the respective tapes and pastes a parting pattern paper on the outside of these bonding agent layers. This zipper, even if it is made of a substance which lacks heat sealing properties between the inner face of the bag and the zipper, can be attached easily to the inside mouth of the bag by pasting up the bonding agent covered by the parting pattern paper, to the inner face of mouth of the bag, by stripping the said parting pattern paper.

Abstract: The present invention relates to an easily separable laminated/perforated film for packings, that can seal the contents under transportation and storage situations and can be formed to the situation for communicating the container interior with the external side when it is to be used.This laminated/perforated film is the film which has bonded both the films in simulation by providing many perforations onto a formed film and by pressing another film which has been extruded from a film forming machine and which is still in a fused state against this perforated film, and this simulation bonding is to be achieved when the film in the fused state has invaded into the perforations of another film.

Abstract: A closed filled bag is formed using a cylindrical mandrel by feeding a bag forming sheet of a heat-sealable film which is of a web and is directed in a manner to one side of the mandrel so that it leaves two marginal edges on the opposite side of the mandrel which are guided into abutting relationship while the body thereof is formed into a cylinder around the mandrel. The zipper tape is fed to the mandrel and it is provided with spaced apart zipper elements which during feeding are folded into juxtaposition so that a U-shaped zipper tape is fed to the mandrel to overlie the two marginal edges which are of the bag forming sheet and the zipper tape has marginal edges below the zipper elements which are secured to the marginal edges of the bag forming sheet.

Abstract: Method of selectively forming an aluminum evaporation film on a surface such as the surface of a container made of plastic film, paper, or glass and of stamping the aluminum evaporation film, by building up the aluminum evaporation film, effecting the stamping work on the aluminum evaporation film or providing the aluminum evaporation film on the surface of a container such as a glass bottle, such as by forming the aluminum evaporation film on one of two films or sheets, applying a hardenable or curable bonding agent meeting or in registry with letters and/or patterns provided on the other of the two films or sheets, then pasting up or joining the two films or sheets together, and thereafter when the bonding agent has hardened, separating the two films or sheets from each other and shifting the aluminum evaporation film to the bonding agent side containing film or sheet.
