FILM FOR THERMAL STERILIZATION PACKAGING |
摘要 |
<p>Provided is a film for thermal sterilization packaging which is excellent in a total balance of characteristics such a transparency, an impact resistance, a heat sealing property, a blocking resistance, a heat resistance and the like. The film for thermal sterilization packaging according to the present invention is characterized by comprising:
an outer layer containing a propylene/ethylene block copolymer (A) which has a melt flow rate (MFR; ASTM D1238, 230°C, load: 2.16 kg) in the range of 1 to 10 g/10 minutes and a melting point in the range of 150 to 170°C measured by means of a differential scanning colorimeter (DSC) and which is constituted from 90 to 80 % by weight of a part (D insol ) insoluble in n-decane at room temperature satisfying the specific requisites and 10 to 20 % by weight of a part (D sol ) soluble in n-decane at room temperature satisfying the specific requisites and
an intermediate layer or an outer layer containing a propylene/ethylene block copolymer (B) which is not the same as the above propylene/ethylene block copolymer (A).</p> |
