Abstract: There is described a new "one-step" bis A-formaldehyde resin, and a molding material containing the resin with which one may achieve molded products possessing excellent properties and almost optimum molding characteristics such as excellent molding latitude, low degree of mold shrinkage, high modulus at elevated temperature, a low degree of deformation at elevated temperatures, and excellent steam crack resistance and electrical properties. The molding material comprises a light colored bis-A formaldehyde resin and reinforcing filler for the resin. The resin is a heat convertible resin (resole) which comprises the product of the reaction of formaldehyde and bis A in the mole ratio of about 2 to about 3.75, in the presence of a catalytic amount of an alkali metal hydroxide or barium hydroxide condensation catalyst. The molding material of this invention is particularly desirable in making molded products by the injection molding or transfer molding processes.

Abstract: A transparent, flexible thermoplastic film having a coating comprising a film-forming polyester resin on a surface thereof is provided, said resin coated surface being readily separable from contiguous surfaces of thermoplastic film after heating at temperatures employed in heat-shrinking thermoplastic film. The resin coated film is particularly suitable for use in preparing stable pallet loads wherein the resin coated film surfaces make possible the ready disassembly of the pallet load without damage to any packaging film used in preparing articles for loading on a pallet.

Abstract: Food casings, particularly cellulosic sausage casings, are moisturized during the conventional shirring operation by applying to the interior of the casing stock prior to shirring an aqueous solution of humectant, the solution containing sufficient humectant to retard excessive imbibition of water by the casing.

Abstract: A multi-ply plastic film article having an openable end is provided comprising a first ply of flat flexible plastic film superimposed over a second ply of flat flexible plastic film and having opposite edges thereof joined and an openable end, at least a portion of the first ply of film defining the openable end being distorted to separate at least a portion of the confronting face of said first ply of film from the opposed confronting face of said second ply of film, whereby the distorted portion of film provides means for readily separating the confronting faces of the first and second plies of film.

Abstract: A flexible heat set biaxially oriented film article having in at least one portion thereof a bead type heat seal is prepared by clamping together adjacent the portion to be heat sealed, superimposed plies of a heat set, biaxially oriented polyester film, said film being characterized as having a tensile strength of at least 15,000 psi and a ratio of tensile strengths in the TD to MD direction between about 0.67 and 1.5, imposing a heat energy source to fuse in a bead type seal the superimposed film and maintaining the plies of film pressed together until the source of heat energy is retracted therefrom.

Abstract: A stick of shirred edible tubular food casing having an end closure comprising casing material defining an end of said shirred casing having the opposing internal surfaces thereof joined across the full width thereof obliquely to the longitudinal edges of said tubular casing, the end closure formed thereby being suitable to block the passage of food emulsion from the end of said tubular food casing.Also provided is a method for heat sealing edible, water-insoluble food casing material which comprises moisturizing at least a portion of one opposing surface of superimposed plies of edible, water-insoluble food casing material to be joined and then imposing heat sealing means with sufficient heat and pressure on the superimposed plies of casing material to join the opposing surfaces thereof together.
