摘要： 1,214,395. Making polypropylene films and sheets. MITSUBISHI PETROCHEMICAL CO. Ltd. 28 Oct., 1968 [27 Oct., 1967], No. 50965/68. Heading B5B. Polypropylene films and sheets are made by melt extruding a crystallizable substantially isotactic polypropylene through a slot die to form a flat molten sheet at least one surface of which is caused to pass over and in contact with a quenching roller, the temperature of the peripheral surface of the roller and the period of contact of any point on the surface of the sheet with the roller being such that the surface of the sheet is cooled to a temperature below the melting point of the polymer while the inner portion of the sheet remains in the molten state. Both surfaces of the sheet are then contacted with quenching water (as by passing through a bath of quenching water) maintained at a temperature not exceeding 40‹ C. Prior to being contacted with the quenching roll the film, after leaving the quenching roll, may be passed over a second quenching roll in such a manner that the other surface of the film is also cooled to below the melting point of the polymer, the inner portion of the film still remaining in a molten state. The molten polypropylene sheet may have a thickness exceeding 0À5 mm., e.g. 1À5 mm. In the examples, a sheet having a thickness of 1À5 mm made according to the process of the invention, may be biaxially stretched at a stretch ratio of 5 in the longitudinal and 7 in the transverse direction to obtain a biaxially stretched film having a thickness of 35 microns. The period of contact of the molten polypropylene sheet with the quenching roller may be in accordance with the expression:- in which:- # = the contact time in seconds; L = the thickness of the sheet in cm.; t 0 = the temperature of the molten polymer in ‹C.; t, = the surface temperature of the quenching roller in ‹C. Quenching water may be ejected from nozzles on to both surfaces of the sheet while it is passed through the quenching bath.

摘要： PURPOSE:To improve stretchability and heat-resistant creep properties by making thermal fusing properties favorable, by a method wherein a thermoplastic elastomer layer selected out of a group comprised of a urethane series superior in heat-resistant creep properties and a thermoplastic elastomer layer superior in thermal fusing properties into polyolefin series resin are laminated through an adhesive polymer layer. CONSTITUTION:The present film is obtained by laminating at least one kind of an elastomer layer selected out of a group comprised of a urethane series thermoplastic elastomer, ester series thermoplastic elastomer and amide series thermoplastic elastomer and at least one kind of an elastomer layer selected out of a group comprised of styrene series thermoplastic elastomer and olefin series thermoplastic elastomer through an adhesive polymer layer possessing properties of an elastomer. That is, since the present film can be stuck to a material such as a polyolefin series thin film or a fiber sheet with a simple thermal fusing method, heat sealing is performed in some places of a mouth part of a bag made of polypropylene with the elastomer laminated film under a condition where it is stretched 2-3 times.

摘要： PURPOSE:To obtain a laminated body which is excellent in contraction and expansion properties, flexibility and heat resistant creep properties by combining and bonding a specified thermoplastic elastomer layer A to a thermoplastic elastomer layer B and thermally melt-sticking the obtained laminated film having contraction and expansion properties to polyolefine-based nonwoven fabric or a film layer. CONSTITUTION:At least one kind of elastomer layer A is utilized which is selected from a group consisting of urethane-based thermoplastic elastomer, ester-based thermoplastic elastomer and amide-based thermoplastic elastomer. At least one kind of elastomer layer B is utilized which is selected from a group consisting of styrene-based thermoplastic elastomer and olefine-based thermoplastic elastomer. The ratio of the layer A to the layer B is regulated to 1/9-9/1 preferably 1/5-5/1. For example, a laminated film having contraction and expansion properties is obtained by making an adhesive polymer present. Then polyolefine-based nonwoven fabric or a film is superposed on this laminated film having contraction and expansion properties and thermally melt-stuck in a state wherein the laminated film is stretched. Thereby the laminated body having contraction and expansion properties is obtained.
