Water-based hot-melt adhesive and water-based hot melt adhesive coated non-woven fabric

Abstract

The present disclosure is to provide a water-based hot-melt adhesive for healthcare packaging. The water-based hot-melt adhesive includes: 10 wt % to 35 wt % of a water-based thermoplastic resin; 20 wt % to 45 wt % of wax particles and 40 wt % to 60 wt % of tackifier; wherein the tackifier including emulsion tackifier and particulate tackifier and the total amount of the particles in the water-based hot-melt adhesive is present at 40 wt % to 65 wt % based on the total weight of the water-based hot-melt adhesive. The coating layer formed on the healthcare packaging substrate from the water-based hot-melt adhesive of the present disclosure has great gas-permeability, and satisfied seal strength and peeling ability after sealing around with flexible sheets or blister containers.
