Water-based adhesives for paper bags and industrial sacks

Bottom Gluing

Bottom gluing is another critical application in bag and sack manufacturing, where the bottom of the bag is reinforced and sealed to provide additional strength and durability. This process involves applying adhesive to the bottom patch, which is then bonded to the sack body. Our water-based adhesives are designed to offer precise and efficient adhesive application:

• High adhesion level
• High tack level
• Suitable for very difficult substrates

Handle attachment

Handles are securely bonded to the bag to ensure ease of carrying and durability. This process requires adhesives that provide strong bond strength and precise application to ensure the handles remain firmly attached during use. Our water-based adhesives are formulated to deliver reliable adhesion for handle attachment, they have:

• Good structural stability
• High initial tack
• Good adhesion on a wide range of substrates

Why does hot melt technology fit the best for paper bag sealing?

Hot melt adhesives are solid at standard temperature and non-hazardous. They become liquid after being heated above their softening point, at which time they can be processed. They can immediately bond the two parts on the substrate by cooling. That adhesive technology contains both natural and synthetic polymers. The melting of the adhesive is processed between 100°c to 170°C, which kills most bacteria and viruses.

Hot melts can fast build up internal strength after cooling, allowing rapid assembly and additional processing. Hot melt adhesives are used in various industrial applications, mainly in food and pharmaceutical environments, as they are free of water and solvent after application. One of the primary users is the packaging sector, such as manufacturing packaging from paper, cardboard, and corrugated board.
