<p>A hot melt adhesive film, on the surface of which a wax emulsion is deposited, ranging from 20 to 100νm in thickness and comprising 60 to 85 wt% of EVA resin containing 20 to 46 wt% of vinyl acetate, and 15 to 40 wt% of C5 to C9 hydrocarbon resins with a softening temperature of 80 to 130°C. The hot melt adhesive film is advantageous in that equipment for its production is simple, a productivity and a working environment are improved because the wax emulsion layer formed on a surface of the hot melt adhesive film acts as a release agent between films so that it is possible to form, store and use the hot melt adhesive film without a further release agent.</p> |
