  • Patent number: 6367513
    Abstract: A scrim of woven polyolefin tapes comprising a plurality of warp tapes in a substantially parallel side-by-side relationship and a plurality of weft tapes in a substantially parallel side-by-side relationship. At least some of each of said warp and said weft tapes being in the form of a tape having at least one of an additional tape and a multifilament yarn superimposed thereon. Each of said tapes is a polyolefin tape. The scrim exhibits improved tear strength properties.

  • Patent number: 6344250
    Abstract: A polyolefin shrink film having high shrinkage and low shrink force. The film has a core layer formed from a polymer of ethylene with a melting point of greater than 100° C., outer layers of a homopolymer of ethylene or propylene or an ethylene/alpha-olefin copolymer. The film is not irradiated. The film may be used in the packaging of articles subject to breakage, distortion or deformation if packaged in shrink films with higher shrink force.

  • Patent number: 6189587
    Abstract: A multi-roll automatic tape splicing device includes a platen which is rotatably mounted on a support frame via a shaft. Two or more tape mandrels are rotatably disposed on the platen at a substantially equal distance from the shaft, and substantially equally spaced from each other, each mandrel being capable of receiving a respective roll of tape. An index drive is operatively coupled to the platen, for selectively rotating the platen so as to successively move each mandrel into a predetermined operating position at which a web of tape can be drawn from a respective roll of tape disposed on the mandrel, and for moving a mandrel out of the operating position when the respective roll of tape is depleted. A first sensor is operatively mounted on the support frame and capable of detecting a depleted condition of a roll of tape mounted on a respective mandrel in the operating position.

  • Patent number: 6062732
    Abstract: A flexible intermediate bulk container having a filling spout extending outwards from one end and a discharge spout extending from the opposed end. A layer of an air-permeable diaphragm and a layer of sheet internal thereto are located at the one end, the opposed end or in wall of container. The diaphragm and sheet are adapted to have a tube therein in fluid communication into the container, through which a vacuum or air pressure may be applied to facilitate filling or discharge of contents.

  • Patent number: 5994242
    Abstract: A coated woven material comprising a layer of a woven scrim formed from a thermoplastic polymer in the form of at least one of fibres, filaments and tapes; and a coating on at least one side of said layer of an elastomeric polymer of ethylene and at least one hydrocarbon alpha-olefin comonomer of at least 4 carbon atoms. The elastomeric polymer has a glass transition temperature (T.sub.g) of less than -20.degree. C. and a brittleness temperature of less than -80.degree. C. The material is particularly useful as a transportation cover.
