PURPOSE:To obtain a sheet for a plastic packing bag improved in deformation or warpage and dimensional stability at the time of high temp. at low cost, also improved in impact resistance at the time of low temp. and prevented from the lowering of aesthetic appearance due to a scratch or a fingerprint. CONSTITUTION:A sheet for a plastic packing bag is characterized by that thickness is 0.1-0.5mm, surface roughness is 0.5-10mum as center line average roughness and deflection is 20mm or less and can be obtained by applying emboss- processing to a plastic sheet with a thickness of 0.1-0.5mm to obtain a sheet with center line average roughness of 0.5-10mum and applying heat treatment to this sheet to set the deflection thereof to 20mm or less. |
