Abstract: A coextruded film having a matte surface layer is prepared by forming the layer from a blend of polyisobutylene and high density polyethylene. The film preferably has a heatseal layer on the other surface. In addition to having low gloss for consumer appeal, the matte surface layer has a medium coefficient of friction for good machinability and excellent heat resistance to facilitate heatsealing. The film is especially useful as an overwrap for packaging consumer products.

Abstract: When a film consisting of high density polyethylene and about three percent polystyrene is run on an interfolding machine to produce interfolded sheets of the film for use as deli wrap, the film is completely and consistently cut in the machine into sheets that are entirely separated from adjacent sheets. In comparison, sheets made from film consisting of 100 percent high density polyethylene are not consistently completely separated from adjacent sheets.

Abstract: The concentration of BHT in a flexible packaging material, such as a cereal liner, can be increased by incorporating the BHT into a polymer composition that is extrusion coated onto a substrate, such as PVDC-coated paper. The extrusion coating comprises a heatseal layer and an EVA tie layer containing the BHT. This method substantially prevents evaporation of the BHT. The extrusion temperature is less than the boiling point of BHT.

Abstract: A jumbo roll of toilet tissue wherein the initial section of the roll is perforated and the remainder is unperforated is dispensed from a dispenser having, in addition to a first spindle for supporting the jumbo roll, a second spindle for receiving the preceding roll of tissue after most of the tissue has been consumed. The spindles are secured by means that discourage pilferage of the rolls but permit access to them by an attendant when the rolls are changed. The second spindle is readily detachable and can be mounted on either side of the dispenser.

Abstract: The bond strength of ethylene-methyl acrylate copolymer to polypropylene is improved synergistically by blending between about 10 and 50 percent ethylene-acrylic acid copolymer with the ethylene-methyl acrylate copolymer.

Abstract: This invention provides an improved web transfer mechanism in a paper roll towel dispenser of the type having a primary roll and a reserve roll of paper toweling. The transfer mechanism comprises a cradle for supporting the primary roll that is counterbalanced by an element for tucking the leading end of the reserve roll into the nip between feed rollers. As the primary roll becomes depleted, the counterbalancing force of the roll decreases, causing the tucking element to gradually approach the leading end of the reserve roll until the element finally engages the end and introduces it into the nip. In a preferred embodiment, the device includes a damper mechanism to prevent premature introduction of the leading end caused by the tendency of the primary roll to rise above the cradle by a sudden pull on the toweling.
