  • Publication number: 20190047772
    Abstract: Provided is a heating pouch that can be heated in hot water and in a microwave. That is, the heating pouch includes a bag sheet provided with an easy peel pressure releasing seal part. In the pressure releasing seal part, one part of a sheet constituting the bag sheet and another part thereof are adhered so as to overlap each other. The pressure releasing seal part peels off when internal pressure rises, to form a degassing passage that communicates between an inside and an outside of the bag sheet. The pressure releasing seal part is provided with an easy peel layer and a skin layer. The skin layer is a resin layer constituting a seal surface that coats at least one of the one part and the other part of the sheet and which adheres to the other part which is not coated. The skin layer has a higher seal strength at 100 degrees centigrade than the easy peel layer.

  • Publication number: 20090301654
    Abstract: In an adhesive sheet, a first coating layer as an adhesive layer is provided to a portion of the adhesive sheet that faces a lens surface. Since the adhesive layer is formed of an adhesive composition containing a (meth)acrylic ester-based polymer, a tackifier resin, and a cross-linking agent, a lens having small friction coefficient and having a surface treated with a fluorine-containing silane compound or the like can be effectively prevented from an axial misalignment due to excellent adhesive strength.

  • Patent number: 7464515
    Abstract: An apparatus is provided for manufacturing a cushioning package containing an article to be packaged. The apparatus includes a cushioning sheet forming unit to form a cushioning sheet by heat-sealing flexible elongated resin sheets which are continuously fed in a longitudinal direction and placed one on another in advance in a width direction of the sheet, the cushioning sheet including small sacs. Downstream from the cushioning sheet forming unit, an article storage space forming unit is provided for forming an article storage space by folding the cushioning sheet along a longitudinal centerline. A sheet adhering unit adheres the overlapped cushioning sheets. An article disposing unit inserts the article to be packaged into the article storage space, and an air filling unit fills the small sacs with air. Sequential performance of the above steps achieves efficient manufacturing of cushioning package.

  • Patent number: 6855356
    Abstract: A packaging body for heat processing a material retained therein is basically formed of a plastic base material having side joining sections, and end sides. The side joining sections and end sides are superposed and connected together to form a bag for filling the material. A sealant layer is deposited on at least one of the end sides to connect the end sides together through the sealant layer to thereby form a vapor communication joining section at the end sides. The sealant layer has a peeling off property from 0 to 1,200 gf/15 mm at 90° C. and a peeling off property of equal to or more than 3 kgf/15 mm at a room temperature. Thus, only when the packaging body is heated more than 90° C., the vapor communication joining section is only opened to release pressure inside the packaging body.
