摘要： A micro-voided film comprising high density polyethylene having a molecular weight of at least about 200,000, and low aspect ratio filler having a mean particle size from about 1 to about 25 microns. The film has a thickness of from about 10 to about 75 microns and a void fraction of from about 0.60 to about 0.75. The micro-voided film is made by a process comprising extruding the composition into a film having a thickness of from about 50 to about 300 microns, and orienting the extruded film using a high stalk, blown film process. The process produces a stabilized high stalk for increasing the production rate of blown, high molecular weight polyethylene, while increasing the film's physical and mechanical properties. The high stalk can be stabilized by application of high velocity, low volume flow rate of air over the interior and exterior surfaces of the extruded film.

(Tm is a melting point (° C.) of the non-porous raw fabric) in an extruding direction (MD) of the raw fabric to make the raw fabric porous; a (D) step: a TD cold stretching step for cold stretching a film processed in the (B) step in a direction (TD) perpendicular to the MD, and an (H) step: a thermal fixing step, in the above order. A thermal fixing temperature T2 (° C.) in the (H) step satisfies expressions (1) and (2) below; T2>T1 (1), (Tm−3)≥T2≥(Tm−40) (2) (in the expressions, T1 represents a stretching temperature (° C.) in the (D) step, and Tm represents the melting point (° C.) of the non-porous raw fabric). A polyolefin-based porous film made of a polyolefin-based resin composition has a pore surface area of 35.0 to 42.0 m2/g and birefringence of 2.0×10−2 to 4.0×10−2.

摘要： The invention provides a heat-shrinkable polyester-based film comprising ethylene terephthalate units, constituent units derived from at least one monomer which forms an amorphous component, and constituent units derived from butanediol. The amount of the constituent units derived from at least one monomer which forms an amorphous component is 18 mol % or more, and the amount of the constituent units derived from butanediol is 1 to 25 mol % based on 100 mol % of all polyester resin components. The heat-shrinkable polyester-based film is characterized by particular values for the secondary shrinkage ratio of the film, the hot-water heat shrinkage ratio of the film, and the reversing heat capacity difference before and after the glass transition temperature of the film.
