THERMOPLASTICS FILM

摘要

53l7(2) Thermoplastics film having a thickness not greater than 100 microns preferably not greater than 50 microns comprising at least 70 wt % high density polyethylene (density not less than 935 kg m-3) characterised in that the film has a total haze (ASTMD 1003-61/70, Procedure A) less than 50% and a clarity (ASTMD 1746-70) of at least 25%. The film can be manufactured by pressing raw polyolefin film between smooth surfaces at a temperature at least sufficient to cause plastic deformation and levelling of the film surface.
