Antistatic Agents for Static-Free Packaging

A method for manufacturing a recyclable and moisture-proof packaging strip that is easy to recycle, has water repellency, low adhesion, and anti-static properties, and is environmentally friendly and moisture-proof. The method involves forming a double coating layer on the inner surface of the paper fabric constituting the packaging strip. The first coating layer is made with an acrylic resin composition. The second coating layer is made with modified calcium carbonate. This provides water repellency, low adhesion, and anti-static properties. The paper fabric with the double coating layer is overlapped and bonded to create a barrel-shaped packaging strip. This eliminates the need for synthetic resin films that can't be easily recycled.
