    摘要： A process for producing an oriented blown film of a thermoplastic resin by blown film extrusion, carried out by blowing air into an extruded bubble of the resin extruded from a ring die to expand the bubble and cooling the expanded bubble with air from a cooling air ring, wherein blown film extrusion is carried out under such conditions that the ratio of (b) the final diameter of the expanded bubble to (a) the diameter of the bubble at the crystallizing temperature of the thermoplastic resin ((b)/(a)) ranges from 1.5 to 10. The process provides an oriented blown film excellent in strength, appearance, and heat shrinkage characteristics.

    摘要： The present invention relates to a film for use in stretch-packaging that comprises an intermediate layer which contains as its main component an .alpha.-olefin-series resin component containing a butene-1-series resin and at least two surface layers each containing an ethylene-vinyl acetate copolymer resin as its main component, the surface layers being laminated over both surfaces of the intermediate layer. The film has remarkably high values of tear strength and recovery from deformation.
