Automatic L Sealer heat shrink wrap machine are widely used in the assembly line of mass production and packaging. It uses an electronic eye to detect products when they pass through the conveyor. After a product passes the sealing arm, the seals fully enclose the product in shrink film. After the seal, products continue to pass into the shrink tunnel. The shrink tunnel machine has recirculating heat to shrink the film to the product evenly. Fully wrapped products exit the tunnel, and the film is conformed tightly to the product.
