PACKAGING FILM FOR THERMALLY MELTABLE ROAD MARKING MATERIAL

摘要

PURPOSE:To prepare a packaging film which has no problem with metal corrosion and is excellent in miscibility and workability during thermal melting with a thermally meltable road marking material, in formability into a film, and in low-temp. heat sealability. CONSTITUTION:This film is obtd. from an ethylene-(meth)acrylate copolymer which comprises 60-95wt.% ethylene units and 40-5wt.% (meth)acrylate units and has a melt flow rate of 0.1-20g/10min at 190 deg.C under 2.16kg load and an m.p. of 110 deg.C or lower measured with a differential scanning calorimeter.
