Used-American Newlong Model PBC-W Double Pinch Bag Heat Sealer.
Used- American Newlong Model PBC-8W Double Pinch Bag Heat Sealer. The PBC-W is a double pinch unit. This machine utilizes a hot air preheat station, a series of heater bars (# of bar sets dependent on required dwell time), and a compression wheel to fuse an inner seal of a multi-wall paper bag with a poly liner. This model also utilizes a creasing wheel to define a consistent fold line and a hot air manifold to activate the pre-applied hot melt adhesive. The bag top folding section will complete the fold and transfer the bag to a non-stick compression belt section. The end result is a well fused inner seal supported by a high strength fold over seal. The temperature is easily adjusted and monitored for best results. The air intake is regulated and digitally monitored for correct pressure. An alarm will be activated if either the heat or the air is out of range and the sealer will automatically shut down to avoid machine damage or bad seals. The bag carrier chain is supported by fixed and spring loaded chain guides. This design prevents bag tops from slipping and / or shifting during the sealing process.
