In this blog post, we’re reviewing a Closing option in the form of the Union Special 80800 Sewing System.

Union Special (US) 80800 Sewing System
The US 80800 Sewing System is a heavy-duty bag closing machine for closing filled bags made from burlap, jute, cotton, plastic, and paper.

It’s manufactured in the United States by Union Special Corporation, which has been in business since 1881. The US 80800 model has been on the market for over 40 years, making it a proven and reliable machine.

The US 80800 is a compact, carrier-chain type heat sealer designed for high-speed, fully automatic, sealing of pinch-bottom open-mouth (PBOM) multi-wall paper bags. It features a creasing wheel to define a consistent fold line and a hot air manifold to activate the pre-applied hot melt adhesive.

Once the fold line is defined and the adhesive is activated, the bag top folding section will complete the fold and transfer the bag to a non-stick compression belt section, providing a well-fused seal.

The bag carrier chain is supported by fixed and spring-loaded chain guides to prevent bag tops from slipping and/or shifting during the sealing process. The temperature is easily adjusted and monitored for best results and the air intake is regulated and digitally monitored for correct pressure.

It can handle both single- and double-pinch bags and is ideal for use in a variety of industries, including food, pet food, chemicals, and more.
