Document Type and Number:
Japanese Patent JP2904903
Kind Code:
B2
Abstract:
A biaxially oriented film mainly composed of a linear low-density polyethylene having a temp. difference between Tmb and Tma of at least 3 deg.C, wherein Tma is a main peak temp. of a melting curve obtd. in the m.pt. measurement with a differential scanning calorimeter by holding a sample at 190 deg.C for 30 mins., lowering the temo. to 20 deg.C at a rate of 100 deg.C/min., and elevating the temp. at a rate of 10 deg.C/min., the Tma being 118 +/- 5 deg.C, and Tmb is a main peak temp. of another melting curve obtd. similarly by holding a sample at 190 deg.C for 30 mins., lowering the temp. to 20 deg.C at a rate of 10 deg.C/min., and elevating the temp. at a rate of 10 deg.C. Since this resin is excellent in stretching stability, it can be stretched with a low tensile strength stably, thereby giving an oriented film excellent in not only stretchability and shrinkage but also elastic recovery. @(37pp Dwg.No.1/1)@.
