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.

Two-component curing adhesive composition for laminating films and packaging materials that is safer, recyclable, and biodegradable compared to traditional reactive adhesives. The adhesive uses an oil or fat containing an acid anhydride group as the adhesive component and a curing agent containing an acid-modified polyol and an amine compound. The acid anhydride groups in the oil react with the hydroxyl groups in the polyol to cure the adhesive. The curing agent amine catalyzes the reaction and improves curing speed. The oil component allows recyclability and biodegradability compared to traditional reactive adhesives.
