Abstract
The present invention provides a water-based hot-melt adhesive for healthcare packaging. The water-based hot-melt adhesive includes 25 to 70 parts by weight of an ethylene vinyl acetate copolymer, 5 to 20 parts by weight of an ethylene acrylic acid copolymer, 6.5 to 55 parts by weight of a water-based paraffin, and 5 to 15 parts by weight of particulate wax, in which a particle size of particulate wax is less than 8 μm. A coating layer formed on a medical paper from the water-based hot-melt adhesive of the present invention has great gas-permeability. After the coating layer is sealed with flexible sheet or blister container at the peripheral edges thereof, it has satisfied seal strength and peelability.
