    Abstract: PURPOSE:To provide the titled film having excellent vacuum moldability, dimensional stability, lubricity and folding processability of a wrapping mount, by molding a vinyl chloride resin contg. a lubricant blended therewith. CONSTITUTION:0.01-3.0pts.wt. lubricant (e.g., synthetic paraffin) having a m.p. or solidifying point of 40 deg.C or above, 10-30pts.wt. plasticizer (e.g. diethyl phthalate) and optionally, additives such as thermal stabilizer, antioxidant, ultraviolet absorber, colorant, etc., are blended with 100pts.wt. vinyl chloride resin to obtain a compsn. The compsn. is molded into a film by T-die extrusion or calendering method, thus obtaining the titled see-through packaging film having a thickness of 20-100mum, tensile stress at yield of 550kg/cm or below and/or tensile stress at 100% modulus of 180kg/cm or above and mold back ratio of 40% or below.

    Abstract: PURPOSE:The titled film having improved transparency and low shrinkage, obtained by blending vinyl chloride resin with inert solid fine particles whose fine pores are filled with an additive for vinyl chloride resin, followed by making the blend into a film. CONSTITUTION:Fine pores of inert solid fine particles are previously filled with an additive for vinyl chloride resin until no occurrence of bubbles is observed when they are immersed in a polypropylene glycol bath heated at 160 deg.C, 100pts.wt. vinyl chloride resin is blended with 0.05-10pts.wt. inert solid fine particles, and made into a film. A plasticizer, a stabilizer, etc. is used as the additive for filling the fine pores, it is melted or dissolved in a solvent and processed into a solution, and it is blended with the inert solid fine particles by a mixer.
