<p>The object of the present invention provides a heat sealing adhesive tape which can adhere to various kinds of products to be treated comprising various polymer materials as the outer surface thereof in a sufficient heat sealing adhesive strength, and enables retention of the adhesive property even under a high heat and humidity. The object is resolved by providing a heat sealing adhesive tape comprising a base layer and a sealant layer formed on at least one surface of the base layer, the sealant layer comprising a hot melt composition comprising an ethylene-vinyl acetate copolymer, a styrenic block copolymer, and a tackifier, the composition having a melting point of 85 °C or lower and a melt flow rate (MFR) of 15.0 g/10 min. or less measured at 190 °C under a load of 2,160g.</p> |
