摘要:
A resin composition comprising: a polyvinyl alcohol; and an inorganic laminar compound having an aspect ratio of not less than 50 and not more than 5000, which has a volume ratio of (inorganic laminar compound/polyvinyl alcohol) in the range of (5/95) to (30/70); and a laminate or laminate film comprising, as at least a portion thereof, a layer or portion (1) comprising such a resin composition. The resin composition, laminate or laminate film may exhibit a good gas barrier property while substantially retaining a good film strength.
摘要:
A resin composition comprising a resin, a hindered piperidinyloxy compound of the formula (I): ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are independently a C.sub.1 -C.sub.4 alkyl group and Z is a hydrogen atom or an organic group having at least one carbon atom, and a hypophosphite compound of the formula:X.sub.a (H.sub.2 PO.sub.2).sub.b (II)wherein X is a metal ion, an ammonium ion or a phosphonium ion, a and b are positive numbers provided that they satisfy the equation: a.times.c=b in which c is a valency of X, wherein a weight ratio of the hypophosphite compound (II) to the hindered piperidinyloxy compound (II) is at least 0.001, which has good heat stability and weather resistance.
摘要:
A method for compatibilizing at least two thermoplastic resins each having hydroxyl group(s), with each other, which method comprises reacting at least one of the thermoplastic resins with a boron compound simultaneously with or before mixing of the resins, to form a boric acid ester at least at the boundary of the resins; a resin composition comprising resins compatibilized with each other, obtained by the method; and a laminate whose at least one layer consists of the resin composition.
摘要:
A laminate, laminate film or shaped article, which includes: a layer of a substance having a gas barrier property; and at least one layer or portion (1) disposed thereon comprising a resin composition comprising a resin and an inorganic laminar compound having an aspect ratio of not less than 50 and not more than 5000. As the gas barrier substance, a metal or oxide, ethylene-vinyl alcohol copolymer, or polyvinylidene chloride may preferably be used. Such a laminate, laminate film or shaped article may exhibit a good gas barrier property which is much higher than that of a conventional plastic material.
摘要:
A film for labels having a high severability in die cutting consisting of a film having a phase separate structure produced by shaping into film a resin composition comprising 20 to 80% by weight a polypropylene resin, and 20 to 80% by weight a polyethylene resin having a density of 0.91 to 0.93 g/cm.sub.3 said film having a Young's modulus of 2000 to 6000 Kg/cm.sup.2 and a thickness of 0.02 to 0.20 mm.

摘要:
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.
摘要:
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.
摘要:
An ethylene-.alpha.-olefin copolymer composition comprising two ethylene-.alpha.-olefin copolymers which are different in density, intrinsic viscosity and the number of short chain branching per 1000 carbon atoms. Extrusion processed materials, injection molded materials and films obtained from said composition are excellent in strength.
