  • Patent number: 6576305
    Abstract: A package comprises a layered coil of filament strands, and a multilayer film surrounding, and in direct contact with, the layered coil of filament strands. The coil has an outer surface comprising a bottom surface region, a side surface region, and a top surface region. The film has an inside surface comprising ionomer in direct contact with the side surface region of the layered coil of filaments. The strand material preferably comprises glass fiber and the sleeve preferably comprises a multilayer film having an outer layer comprising ionomer. Preferably, the film has a stiffness sufficient to maintain structural integrity of the package as the strands are being removed in order to prevent collapse of the side walls of the package and entanglement of the strands.

  • Patent number: 6439383
    Abstract: A method for packaging fiber glass rovings is provided which substantially reduces the amount of material needed to securely package the rovings for shipment and/or in-process storage and handling. Also provided is a method for packaging fiber glass rovings which permits the packaging material to be reused. In a preferred embodiment the method comprises stacking fiber glass rovings on a shipping pallet; placing curved panels vertically at least at the four corners of the assembly of stacked rovings, said panels being approximately semi-cylindrical and having a height at least as great as the height of a column of stacked rovings; placing support members among the stacked rovings, said support members having a combined compressive strength sufficient to support the weight of a second pallet of stacked rovings; placing a top cap over the assembly of rovings, panels and support members; and thereafter wrapping the assembly with a stretch wrap material.
