Water-based hot-melt adhesive and nonwoven coated with the water-based hot-melt adhesive

Abstract

The present invention is to provide a water-based hot-melt adhesive for healthcare packaging. The water-based hot-melt adhesive includes 20 to 60 weight parts of hydrophilic-modified water-based polyolefin resin; 1 to 30 weight parts of water-based ionomer; 10 to 30 weight parts of wax particles; and 10 to 30 weight parts of tackifier particles. The coating layer formed on the healthcare packaging substrate from the water-based hot-melt adhesive of the present invention has great gas-permeability and weather resistance, and the healthcare packaging substrate with the water-based hot-melt adhesive of the present invention has satisfied seal strength, pealing ability and reliability after sealing with flexible sheet or blister containers at the peripheral edges thereof.
