The present invention relates to an ornamental laminate film made from at least an inside film and an outside film, provided with a letter and/or a pattern by printing and as a raised part protruding toward the outside film. At least apart of the letter and/or the pattern has a metallic luster and differs in at least one of hue, brightness, chroma and glossiness from a region other than the letter and/or the pattern, and the raised part is formed along at least a part of the letter and/or the pattern. As a result of that, an ornamental laminate film with excellent design is provided without impairing its function as a packaging material.

Laminate film, and pouch-type container and sealing material having ornamental laminate film

To provide a microwave pouch that favorably prevents both of hole formation of the pouch and spurting of contents, with a simple structure. A microwave pouch () includes a self-venting mechanism (). The self-venting mechanism () has an annular venting seal (), a steam release part () surrounded by the venting seal (), and a movable piece () defined by a slit () formed in the steam release part (). The venting seal () has a seal peel initiation part () where peeling is started by steam generated inside the pouch () during heating. The slit () includes slit both ends (), and a slit intermediate part () formed to extend from the slit both ends () toward a region away from the seal peel initiation part () and connecting the slit both ends.

Microwave pouch

A packaging bag composed of a multilayer film and having a steam releasing mechanism. The multilayer film has at least a base layer and a welding layer and has a moisture content of not more than 1.0% in a state in which the packaging bag is filled with a content. The steam releasing mechanism has at least a steam releasing portion formed to have a maximal width of 3 to 20 mm. The internal pressure of the packaging bag is kept to be not more than 115 kPa during a period from the time the internal pressure is released through the steam releasing portion as a result of an increase in the internal pressure caused by heating in a microwave oven to the time the heating in the microwave oven finishes.

A pouch with a nozzle has a reliable dispensing opening. The pouch holds liquid contents. The pouch has a shell portion formed by sealing two plies of plastic together to form a pouch volume and a nozzle portion which communicates with the inside of the shell portion. The nozzle portion is formed by a series of embossments which form a reliably open passage for dispensing fluid. Three sets of embossments include a plane shape, a dot shape or a line shape.

Pouch container

A pouch is formed out of two sheets of plastic heat sealed over most of the edge length. The pouch has an expanding bottom feature and has a pouring spout formed by raised impressions in the corresponding sheets of plastic that form matching embossments. When the pouch is squeezed, the embossments open further apart to form a larger fluid passage at the outlet. The outlet of the pouch is opposite the bottom of the pouch and in at least one embodiment has a region on both sides of the outlet that are kept free from heat sealing during manufacture. The outlet also has a frangible line of weakness for easy opening. The outlet passage has two sets of embossments that meet along a center line to more fully expand the central portion of the pouch.

Pouch for refill of contents

A branch type standing pouch which includes a pouch front side member including a pouring-out nozzle backside portion which constitutes a backside of a pouring-out nozzle by being folded back and a pouch body front side portion continuous therewith; a pouch backside member constituting a backside of the pouch body; a pouring-out nozzle front side member; and a bottom member. The pouch front side member, the pouch backside member, the pouring-out nozzle front side member, and the bottom member are respectively formed of plastic film and heat-sealed to each other so that a pouring-out nozzle is formed in a branched manner from a top of a pouch body. In this pouch, two symmetrical nozzle reinforcing areas are formed on both sides of a first protrusion as a result of a provision of the first to fourth protrusions. As a result, the branch type standing pouch in which the pouring-out nozzle can be fixed upright at a time of opening is obtained.
