    摘要： The present invention provides a biaxially oriented film of a polylactic acid resin that is suitable for films for bags and packaging films for various windows, particularly films for outlook window envelopes. The film is biodegradable and, as films for outlook window envelopes, is superior in the coating adaptability for an antistatic agent, a lubricant and an antiblocking agent or the like and in the high-speed cutting property.The present invention discloses a biaxially oriented film of a polylactic acid resin comprising not less than 50% by weight of a polylactic acid resin, which has a storage modulus E′at 80° C. within the range from 10 MPa to 3,000 MPa, as determined by the test method for temperature dependency of dynamic viscoelasticity, in accordance with JIS K7198 (method A); a heat shrinkage of not higher than 10%, upon heating at 80° C. for 10 seconds; and a tear strength in the width direction (TD direction) of the film of 10 to 200 mN, as determined in accordance with JIS K7128 (method B).

    摘要： A wrap film having very stable physical properties wherein a sock liquid maintains the lubricating effect as an opening agent while a sock is stabilized and parison width changes and meandering are reduced to eliminate parison wrinkles is provided. Specifically, the wrap film is a wrap film made of a polyvinylidene chloride-based resin prepared by melt-extruding a polyvinylidene chloride-based resin from a die in tubular form, cooling the outer side of the extrudate by using a coolant while an aqueous solution of a liquid that is compatible with water and forms one-component is retained in the hollow portion of the extrudate, and inflating the solidified extrudate, wherein the liquid that is compatible with water and forms one-component has a concentration of 80 to 95% by mass in the aqueous solution, and the liquid is applied to the wrap film in amounts of 50 to 4,000 ppm.
