Abstract: A reusable packaging system includes a series of four bags, each designed to be reusable and capable of standing upright when in an open state. The bags are constructed so that they will fit in an open state within a shopping cart, and differ progressively in size so that they can be nested inside of each other for storage. The nested bags are then folded to form a compact, single package which can be easily transported by a user to a store for shopping.

Abstract: A packing bag structure formed of inner and outer bag members made of synthetic resin inner and outer films having different moisture permeabilities enables easy-to-dry moist foods or other perishable products to be packed in a suitable state and stored in a non-soggy and untarnished condition. The inner film has moisture permeability of 9 to 200 g/(m2·24 h), preferably 20 to 30 g/(m2·24 h), and the outer film has moisture permeability of 4 to 15 g/(m2·24 h), preferably 7 to 10 g/(m2·24 h). The packing bag is produced by folding a long film sheet formed of the inner and outer films into two, having an article such as food placed between the twofold film sheet, thermally sealing the film sheet by using an end sealer and cutting off the packed and sealed portion.

Abstract: Methods for manufacturing airtight storage containers (e.g., bags or pouches) made from thermoplastic web material and having heat-sealed margins along a perimeter. To ensure that the storage containers are airtight, an unheated rib is pressed along each heat seal while the web material in the region of each heat seal is still in a softened and pliable state. As a result of the pressure applied, the rib deforms the contacted portion of the heat-sealed web material, leaving an indentation upon cooling of the web material that serves as an air leakage barrier. This air leakage barrier ensures that any air leakage pathway across the heat seal region is closed.

Abstract: The envelope comprises layers of plain un-coated kraft paper and of bubble-wrap polyethylene. A stack of the layers is joined at the marginal edges of the envelope by squeezing the stack between a pair of points-dies, which are formed with points that puncture the kraft paper but do not puncture the polyethylene. The points push crowns of un-punctured polyethylene through the punctured boles in the paper. Then, the marginal edges are squeezed flat between flat-dies, the flat-dies being heated enough to cause fuse-bonding. The margins of the finished envelope are held together not only by fuse-bonding, but by the presence of the crowns, which, penetrating right through the holes in the paper, serve as mechanical rivets.

Abstract: An improved pressure vessel comprising a polymer inner bladder inside a containment envelope is provided which is well-suited for transporting hazardous materials therewithin via air transport. The improved pressure vessel features a seal placed over the closure of the containment envelope which has been found to suppress failure of the pressure vessel by creep which occurs as a result of the high internal pressure that the pressure vessel experiences at high altitudes. The seal also serves to indicate whether or not the containment envelope has been tampered with after having been sealed.
