摘要： A polyolefin resin composition obtained by mixing a polyolefin resin with minor proportion of a polybutene of low molecular weight, a mixed glyceride containing a lower acyl group and a higher acyl group, and preferably a surface wetting agent, is used to form a polyolefin film, which is thereafter aged. The thus formed film exhibits very excellent adhesion strength as well as very good transparency and physical strength, and is therefore suitable for use as a food packaging film.

摘要： A photographic support comprising a paper substrate and the resin layers formed on both sides thereof, each of the resin layers being made of a resin composition comprising a polyethylene resin, wherein the difference in thickness between the resin layer on the side on which a photographic layer is to be provided and the resin layer on the opposite side is 3 .mu.m or greater, and the polyethylene resin in the resin layer on the side opposite from the photographic layer is a compounded resin prepared by melting and mixing a specified number of parts by weight of a specific low-density or medium-density polyethylene resin and a specified number of parts by weight of a specific high-density polyethylene resin. This resin-coated paper type photographic support has good adhesion between the base paper and the resin layer on the side opposite from the photographic layer, excellent in qualities such as anticurl properties, cutting properties and capable of high-speed production.

摘要： In apparatus for forming an inflation film of the type wherein a molten resin is ejected through a circular slit of a die, gas is blown into a resulting cylindrical film for inflating the film, and the cylindrical film is cooled by air ejected by an air ring, the air ring comprises an outer lip and an inner lip disposed closer to the die than the outer lip. The outer and inner lips form an air passage terminated with an air ejecting port, and the inner diameter of the outer lip increases in the direction of withdrawal of the cylindrical film. The air pressure in a space between the outer lip and the cylindrical film is reduced by Venturi tube effect or an evacuation device.
