Abstract: A resealable bag is formed of flexible sheet material having, embedded therein, a number of parallel, spaced apart strips of inelastic but bendable material which are capable of assuming a set position when bent. The strips, which extend generally longitudinally along the full length of the bags, each include a substantially widened portion, near the mouth of the bag, which co-operates with the flexible package walls to form a closure for resealing the package. A series of filled bags may be formed by first forming a continuous length of a flexible two-ply sheet material having a number of strips disposed between the plies. The end of the sheet is drawn past a hollow mandrel so as to bring the sheet edges into overlapping relation. The overlapped edges are joined to form a tube, the end of which is sealed with a transverse seam to form an open-ended bag. The open bag is then filled through the mandrel, sealed with a transverse seam and severed from the length of material.

Abstract: A reusable bag for storing items. The bag has a band located over at least part of the bag's outer surface. The band is detachably secured to the bag with an adhesive. To reseal the bag after opening, the band is partially lifted away from the bag. A space is thus created between the band and the bag into which the twisted end of the bag may be inserted and secured. The band contains adhesive on only a center region of the band to permit the band to be easily separated from the bag and so that user contact with the band does leave adhesive on the user's fingers or wear adhesive from the band.
