Abstract: In an embodiment of the invention, a bottom seal of a plastic bag is strengthened by welding together 8 layers of plastic film. In one respect, an embodiment of the invention provides an apparatus configured to weld together 8 layers of plastic film on a bottom edge of a folded bag, and then unfold the bag. The apparatus may also stack multiple unfolded bags into a bag pack.

Abstract: In an embodiment of the invention, a bottom seal of a plastic bag is strengthened by welding together 8 layers of plastic film. In one respect, an embodiment of the invention provides a bag pack that includes multiple T-shirt style plastic bags. The bag pack may be manufactured by folding a 4-layered structure into an 8-layered structure, welding a bottom edge, and then unfolding the 8-layered structure before stacking 4-layered bags into a bag pack.

Abstract: A multilayer film which loses its memory when subjected to heat shrinking comprising at least three layers, wherein at least one of the layers comprises a styrene-butadiene copolymer and the other layers comprise at least one material selected from the group consisting of HDPE, LLDPE and LDPE.

Abstract: A method of forming a load for transportation comprising the steps of: i) placing a base member on a flat surface, wherein the base member is wider than the intended width of the load; ii) forming a base layer of the load on the base member such that a side flap of the base member extends beyond each side of the base layer, wherein the base layer defines at least two channels for receiving forks of a forklift truck or other lifting device; iii) building a partial load, less than the intended maximum height, on top of the base layer iv) folding the side flaps of the base member around the partial load; v) building the remainder of the load on top of the folded base member; and vi) securing the completed load for transportation.

Abstract: A sheet material dispenser comprising a container and a stack of folded sheet material, the container surrounding the sheet material and having an aperture through which the sheet material may be drawn in use of the dispenser, wherein the sheet material is folded within the container in a concertina manner.

Abstract: An apparatus for vacuum packing a product (1) in a flexible enclosure (2) therefor, the apparatus comprising means (6, 7) for evacuating air from within the unsealed enclosure (2), the product (1) being disposed within the unsealed enclosure (2), means (18, 19) for restraining sealable meeting portions (3a, 3b) of the unsealed enclosure (2), during the said evacuation of air, in a configuration whereby the said sealable meeting portions (3a, 3b) can be sealed without substantial rucking thereof and means (33, 34) for sealing the sealable meeting portions (3a, 3b) of the unsealed enclosure (2) in an airtight manner in the said configuration thereof, after the said evacuation of air.

Abstract: Synthetic polyolefin films of one or more layers, wherein each layer may be of a different thickness and a different formulation. The films consist of a polyolefin resin and a suitable mineral filler of at least three microns in particle size. The films are particularly useful as a masking material in paint overspray protection systems and may be used to protect a finished surface from moisture and/or ultraviolet radiation. The films posses the advantage that their use does not result in staining or ghosting on the protected or masked surface.
