Abstract: A laminate film for wrapping which comprises a layer comprising (A) an ethylene-.alpha.-olefin copolymer having a coefficient of variation of composition distribution (Cx) represented by equation shown below of 0.40 or less and having an ethylene content of 50 mol % or more and at least one layer of a different kind;Cx=.sigma./SCB.sub.avewherein .sigma. is a standard deviation of composition distribution (1/1000 C), and SCB.sub.ave is an average of the number of short chain branchings per 1000 C (1/1000 C).The film is safe and hygienic, less odorous and excellent in transparency, mechanical strength, softness, and low-temperature heat sealing properties and is therefore suitable to automatic wrapping, particularly stretch-wrapping.

Abstract: An oxygen absorbing sheet is disclosed, which is obtained by molding a resin composition comprising from 15 to 70% by weight of a thermoplastic resin and from 30 to 85% by weight of an oxygen absorbent into a sheet having a thickness of from 10 .mu.m to 5 mm and stretching the sheet at least uniaxially at a stretch ratio of from 1.5 to 8.0. The oxygen absorbing sheet is easy to handle, and its oxygen absorption capacity is arbitrarily controllable.

Abstract: A mulching film which comprises a reflective film layer having a reflective peak at a wavelength of less than 0.4 .mu.m and a reflective spectrum having not less than 1.4 of a ratio (R.sub.A /R.sub.B) of the ultraviolet peak reflectance (R.sub.A) and the visible light reflectance at a wavelength of 0.5 .mu.m (R.sub.B) and a black film layer, which is effective for repelling insect pests harmful for various crops and other plants by covering ground for plantation and for lowering of the underground temperature and also for the prevention of the propagation of weeds.

Abstract: A breathable film and a process for producing the same are disclosed, the breathable film comprising a resin composition comprising (1) 100 parts by weight of a linear low-density polyethylene resin having a density of from 0.870 to 0.915 g/cm.sup.3 and containing from 15 to 50% by weight of a component which is extractable with xylene at room temperature and which has a weight average molecular chain length of from 1,000 to 9,000 .ANG.; (2) from 50 to 400 parts by weight of a filler; and optionally, (3) from 0.5 to 8 parts by weight of a nonionic surface active agent. The breathable film of the invention not only has excellent film moldability and film stretchability but also shows high breathability, good touch and appearance, and high strength.

Abstract: An insect pest-repelling film or sheet is disclosed, having a reflective spectrum in a ultraviolet region of a wavelength of less than 0.4 .mu.m, particularly a reflective spectrum peak at a wavelength of less than 0.4 .mu.m, a reflective spectrum having not less than 1.4 of a ratio (R.sub.A /R.sub.B) of the ultraviolet reflectance (R.sub.A) and a visible light reflectance of a wavelength of 0.5 .mu.m (R.sub.B) and a visible light transmission of not less than 40%. The film is useful as a cover of houses and tunnels or mulching of ground for crop culture or as a repellent for various insect pests in agriculture, forestry, and gardening.
