本考案はマイクロウエーブを用いて袋内の内容
物を加熱、調理する際に使用する包装袋に関す
る。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a packaging bag used when heating and cooking the contents inside the bag using microwaves.
（従来の技術）
従来、電子レンジなどの誘電加熱によりポツプ

に開封しなかつたり、或は袋材料自体がマイクロ
ウエーブの透過が悪かつたりする等の欠点があつ
た。(Prior Art) Conventionally, popcorn and the like have been cooked using dielectric heating in a microwave oven, etc., but in this case, the steam pressure inside the bag must be discharged to the outside of the bag by heating, and at the same time the popcorn must be expanded. Conventional bags often had drawbacks such as not being able to reliably open the bag at the desired vapor pressure, or the bag material itself having poor microwave permeability.

る。(Problems to be Solved by the Invention) The present invention improves the above-mentioned drawbacks, has good microwave penetration, can sufficiently heat the inside evenly by dielectric heating, and can easily cover the whole or part of the sealing part at a desired vapor pressure. As a result of various studies regarding the packaging bags to be opened by the department, the present invention was completed.

る。(Means for solving the problem) The present invention uses polyethylene with a thickness of about 10 to 100μ,
A heat-resistant synthetic resin base film 1 made of polypropylene, polyester, cellophane, polyamide, etc. is coated with an adhesive such as ethylene-vinyl acetate copolymer acrylic, vinyl acetate, or rubber in the form of dots or lines. On top of this, a paper base material 2 such as high-quality paper or dry kraft paper is superimposed and laminated with adhesive, and on the other side, an easy-open sealing agent 3 having thermal adhesive properties is applied. A packaging bag is formed by applying a layer of about 10 g/m 2 to the required area and using the obtained laminated material.For example, if the base film is polyester, polyester is used as the main ingredient. Approximately 5 to 40% of an acrylic synthetic resin having adhesive properties is added and mixed.
上記のようにして得られた積層材を用い紙基材

る。(Effects) In the packaging bag of the present invention, the paper base material is adhered to one surface of the synthetic resin base film using an adhesive partially applied, and the other surface is covered with an easy-to-open seal. The synthetic resin film, paper base material, and sealant all have low dielectric constants and good microwave transmission, and the synthetic resin film and paper base material have low dielectric constants and good microwave transmission. Since it is partially adhered to the base material, there is a space between them, so there is no attenuation of microwaves, making it highly efficient.Furthermore, both base materials are heat resistant and can withstand heating in a microwave oven. At the same time, when a packaging bag is constructed using this laminated material with the paper base material as the outer surface, the entire contents filled in the bag are heated uniformly, and the presence of an easy-to-open sealant allows the bag to be opened at a desired vapor pressure. It has the following effects.
