Abstract: A method of manufacturing a biaxially oriented heat-shrinkable food packaging film comprising a three component blend wherein the major constituents are a polyethylene, such as, VLDPE or LLDPE or a mixture thereof, EVA, and an ethylene alpha-olefin plastomer copolymer of a density below about 0.90 g/cm.sup.3.
Abstract: A biaxially stretched film with very high heat shrink and puncture resistance properties, formed of low density ethylene alpha olefin copolymer having low melt index, low Mw/Mn, low melting point and low Young's Modulus.
Abstract: A tar-containing aqueous liquid wood smoke is extracted with selected organic liquid solvents to form a tar-enriched liquid fraction and a tar-depleted aqueous liquid smoke fraction, the latter being used for food casing treatment to facilitate smoke coloring and flavoring of encased foodstuff during processing.
Abstract: A gas-liquid contacting tray of the crossflow type with improved means for initiating bubbling activity at the tray inlet region comprising spaced-apart imperforate wall members extending substantially vertically upwardly and transverse to the liquid flow path, contiguously associated and coextensive at their upper edges with an intermediate perforated wall member horizontally extending therebetween.
