THE METHOD OF PREPARING FILTER PAPER COATED BY CROSS STRIPES WITH HOT MELT RESIN'S COMPASSION FOR PACKAGE OF MEDICINE TOOL

摘要

PURPOSE: A method of preparing filter paper having a lattice pattern using hot melt resin having adhesion property when softened at elevated temperature or in molten state as a main component is provided. Whereby, the product does not generate toxic vapor or gas and destruct a medical device because of using no organic solvent. CONSTITUTION: About 30 to 40% by weight of an ethylene vinylacetate copolymer, 50 to 60% by weight of paraffin wax, 5% by weight of polyethylene, 4% by weight of SIS(Styrene-Isoprene-Styrene) and 1% by weight of an antioxidant are blended at 150 to 170deg.C for 12hr to produce a coating liquid. Thereafter, the coating liquid is passed through a roller in which a lattice pattern is engraved.
