The present invention relates to a polyester coating composition used for forming a coating film of a coated metal plate, a metal container, a metal closure, etc. The coating composition has a crosslinking agent and a curing catalyst incorporated into a mixed polyester resin comprising a mixture of a polyester resin (A) having an acid value of 2 to 50 mg KOH/g and a glass transition temperature (Tg) of 35 to 100&#xb0; C. and a polyester resin (B) having an acid value of 0 to 50 mg KOH/g and a glass transition temperature (Tg) of &#x2212;20 to 25&#xb0; C. Thus, a coating composition excellent in resistance to embrittlement over time, corrosion resistance, scrape resistance, retort resistance, and blocking resistance can be provided.

Coating composition and coated metal plate, metal container and metal closure coated with the coating composition

An object of the present invention is to provide an organic-resin-coated metal sheet for beverages and foods having retort blushing resistance and can manufacturability, a manufacturing method thereof, and a metal can and a can lid that are made by processing the organic-resin-coated metal sheet. An organic-resin-coated metal sheet of the present invention is an organic-resin-coated metal sheet in which an unstretched film is stacked on at least a single surface of a metal sheet, and is characterized in that the unstretched film is composed of a polyester-based resin composition obtained by blending copolymerized polyester (I) composed mainly of a polyethylene terephthalate-based resin with crystalline polyester (II) composed mainly of a polybutylene terephthalate-based resin with a mixing amount of the crystalline polyester (II) of 20 to 45 wt %.

Organic-resin-coated metal sheet, process for producing same, metallic can obtained by processing said organic-resin-coated metal sheet, and can lid

At least one of an obverse surface film and reverse surface film, which are used to together constitute a plastic pouch, is folded back across the entire width of the plastic pouch, and peripheral edge portions of the pouch are heat-sealed, to thereby form, on at least one position, a folded-back section communicating with the body of the pouch.

Plastic pouch and manufacturing method therefor

Provided is a packaging pouch for a microwave oven, provided with a steam releasing seal portion having a weakened portion, in which no clogging occurs in the steam releasing seal portion at the time of heat-cooking in a microwave oven, and any clogging occurred can be automatically eliminated. In the present invention, hermetic sealing is effected through heat sealing of a plastic film, and at least one steam releasing seal portion having a weakened portion is provided, with a width of the weakened portion gradually increasing from a forward end portion thereof to be opened toward a rear end portion thereof.

Packaging pouch for microwave oven

A packaging container which includes a synthetic resin container body having a flange part and the cover member heat-sealed to the flange part of the container body. The cover member includes (1) an upper member in which inner surfaces of resin films are positioned opposite to each other to form an abutted part, an unsealed part communicating with the inside of the container body is formed by heat-sealing a peripheral edge part of the abutted part excluding one side of the abutted part forming a base part, and the steam releasing seal part is formed at the abutted part and (2) a lower member which covers a lower surface of the upper member and in which a steam guide part communicating with the inside of the container body is formed at or near the base part of the abutted part.

Packaging container for cooking by electronic oven

Provided are a packaging container for a microwave oven that excels in the sealing performance between a container body and lid, and that at heating/cooking by a microwave oven, maintains the internal pressure of the container for a given period of time to thereby enhance the taste of contents through steaming effect, and that thereafter, can spontaneously open with certainty from a steam releasing seal part; and an efficient process for manufacturing the packaging container. In the packaging container for microwave oven having a lid heat-sealed to the periphery of a flange part of container body made of a synthetic resin so as to attain hermetic sealing, at least one steam releasing seal part with a weakened part is disposed inside the peripheral seal part of the flange part at a position separate from the peripheral seal part.

Packaging container for microwave oven and process for manufacturing the same

An inexpensive packaging pouch for use in a microwave oven, in which the packaging pouch can be prevented from opening at the base part of a branch section when used for retorting or for cooking in the microwave oven, and pressure in the packaging pouch can be automatically released when the pouch is used for cooking in the microwave oven. A packaging pouch for microwave oven hermetically sealed by heat-sealing a plastic film is provided with a branch section, and a vapor release seal part having at least one weakened part is formed at the branch section. Opening preventive means are provided at the branch section and inside a peripheral edge seal part, facing the branch section, of a packaging pouch body.
