Abstract: The present invention is to provide an anti-glare film. The anti-glare film comprises a transparent substrate and an anti-glare layer formed on a surface of the transparent substrate, wherein the anti-glare layer comprises an acrylate binder resin and a plurality of silica microparticles, wherein the particle size of the silica microparticles is ranging between 2 μm and 6 μm and the BET specific surface area is not more than 250 m2/g, and the amount of the silica microparticles is ranging between 3 to 20 parts by weight per hundred parts by weight of the acrylate binder resin. The anti-glare film provides an enhanced abrasion-resistance.

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.
