摘要： PROBLEM TO BE SOLVED: To facilitate the reduction of the volume, and reduce an environmental load by a method wherein a plurality of polyhedron shaped air bubbles which are formed of a plurality of polygonal films, and have a sealed gas chamber inside are bonded. SOLUTION: A cushioning material 10 is constituted of a plurality of polyhedron shaped air bubbles 11, and the polyhedron shaped air bubble 11 is formed of a plurality of polygonal films 12. Such a cushioning material can be formed so as to meet the shape of an article to be packaged such as a precise machine, in the same manner as an expanded plastic. Also, compared to the cell of an expanded plastic, it is an aggregate of extremely large polyhedron shaped air bubbles, and the volume can be reduced by using a cutter, etc., on the market, after the usage. For the shape of the polyhedron shaped air bubble 11, from the viewpoint of a production, a tetrahedron which is constituted of four triangles, is preferable. In addition, when the tetrahedron is formed in such a manner that after a film is formed into a cylindrical shape for one time, a sealing is performed so as to be orthogonal to the axial direction of the cylinder, it is desirable that respective two triangles among the four triangles have the same shape.

摘要： PROBLEM TO BE SOLVED: To advantageously packaging an object utilizing pressure sensitivity of a packaging material comprising a cellular sheet with polyolefin as a material by using polyolefin having long-chain branches manufactured by using a single- site catalyst. SOLUTION: A cellular sheet 1 which is sufficiently larger than an object 7 to be packaged and has an extension with overlaps formed when the object 7 is wrapped is prepared. The object 7 is put on the sheet 1. Then an upper side piece and a lower side piece of the cellular sheet are sequentially overlaid along the object to press the overlaps. A left excessive piece and a right excessive piece are entirely pressed from up and down respectively, whereby the cellular sheet 1 self-tacks so that a package can keep its state if specific processing for fixing with an adhesive tape is not done. Thus the object can be packaged with reduced labor and materials.

摘要： PROBLEM TO BE SOLVED: To improve heat resistance and flame retardancy as an insulating and protective material for a pipeline and a chemical by constituting the title sheet by a specified number of films using a polyvinylidene fluoride resin obtd. by graft-polymerizing a crystalline fluororesin on a fluororubber as a material. SOLUTION: An air bubble sheet 10 prepd. by using a polyvinylidene fluoride resin prepd. by graft-polymerizing a crystalline fluororesin on a fluororubber comprises a cap film 11 prepd. by applying uneven processing on the surface of this material and a flat back film 12 and both films are laminated by such a method as hot welding. Air bubbles 13 prepd. by sealing recessed parts of the cap film 11 are formed thereby. Therefore, based on the characteristics of the polyvinylidene fluoride resin, as it is excellent in flame retardancy, heat resistance, chem. resistance and weatherability and is hardly stained and is easily processed by cutting and handled, it can be used for an insulating sheet for a filmy structure and agricultural applications and for pharmaceutical uses, etc.

摘要： PROBLEM TO BE SOLVED: To improve the packaging workability of a plastic cellular sheet when used as a packaging material. SOLUTION: On a long-sized plastic cellular sheet which is rolled, a perforation 2A is provided in the direction to cross the sheet, with a specified interval to facilitate a cutting. The perforation is provided in the longitudinal direction as well if necessary. The locations of the perforations are marked by applying a printing, or an indication by affixing a small piece of paper is recommended. When an adhesive tape is affixed along at least one edge of the sheet 1, or an adhesive is applied into a band-shape or on the whole surface, the binding or fixation after an article to be packaged has been packaged becomes easier.

摘要： PROBLEM TO BE SOLVED: To manufacture a polyhedral hollow body with a lightweight structure such as a honeycomb structure and the same strength in three axial directions by bonding a plurality of polyhedral hollow bodies being formed of a plurality of polygonal films or sheets and with a tightly closed inside. SOLUTION: A hollow structural body is constituted of a plurality of polyhedral cores formed of films or sheets. e.g. two cores 33 of triangular pyramids each constituted of two sheets of right-angled triangles with the same shape and a ratio of the sides of 1:2 :3 and two sheets of right-angled isosceles triangles with a ratio of the sides of 1:1:2 and a core 34 of triangular pyramid being symmetric with respect to a plane or a core 33 of the triangular pyramid and two cores 34 of the triangular pyramids are sticked together in such a way that both faces of symmetric right-angled triangles are clasped in prayer to obtain a triangle prism 32 with the top and bottom right-angled isosceles triangles. When two of these triangle prisms are combined, a cube 31 is obtd. A hollow structural body can be easily constructed by using this cube 31 as a secondary unit.
