BEST MODE FOR CARRYING OUT THE INVENTION The envelope body is made of, for example, high-quality paper, coated paper, kraft paper, synthetic paper or the like, synthetic paper, plastic film such as polypropylene, or the like having a mechanical strength capable of withstanding envelope processing. It may be obtained by selecting an item having a grammage and a thickness having, and appropriately performing envelope processing. For example, in the case of a paper envelope, high-quality paper of 40K to 130K can be used, and can be obtained by continuously bag-processing from two rolls of a predetermined width using a glue processing machine such as a roll collator. Also,
The folded-back piece may be provided and configured to be hermetically sealable with an adhesive such as an aqueous glue, but it is not necessarily required to have a configuration capable of hermetically sealing and may be stuck in an opened state.

The adhesive sheet is made of high-quality paper, coated paper, kraft paper, synthetic paper or the like, or polyester film, polyvinyl chloride film, plastic film such as polyolefin film, etc., and has a thickness of 20 to 300 μm, preferably 50. A rubber-based or acrylic-based pressure-sensitive adhesive is applied and formed on the back surface of the adhesive sheet base material having a thickness of ˜200 μm and a thickness of 10 to 1
A pressure-sensitive adhesive layer having a thickness of 00 μm, preferably 20 to 60 μm may be provided.

Any type of pressure-sensitive adhesive may be used, but it is preferable to use a re-peeling pressure-sensitive adhesive in order to make it stickable. Further, in the case where an adhesive layer is provided on the back surface of the adhesive sheet body which is formed by releasably attaching a transparent synthetic resin film to the back surface of the adhesive sheet base material, for example,
A so-called pseudo-adhesive sheet in which a paper or film base material and a transparent synthetic resin film are pseudo-adhered may be used. Further, it is preferable that the pressure-sensitive adhesive sheet is formed to have substantially the same size as the envelope body.

The envelope body and the sticking sheet are made of a pressure-sensitive adhesive, a heat-sensitive adhesive, a moisture-sensitive adhesive, a hot-melt adhesive or the like. At least a part of the envelope sheet is fitted in a separated state, but it is preferable that the envelope body is placed in a separated state over the entire peripheral edge portion of the adhesive sheet.

Incidentally, it is preferable to attach a release sheet having a silicone release layer or the like on one side of a release substrate made of paper or film to the back surface of the pressure-sensitive adhesive layer of the adhesive sheet.
