This semi auto sealer series has a compact structure and small footprint. We can press the start button after the products are fed by hand. Then the products will be sealed and shrank automatically. Therefore the speed of packing is based on the speed of our feeding by man. The semi automatic sealer is suitable for packaging cartons, beer, beverages, cosmetics, condiments, etc, which we don't need to link with the automatic product feeding line.There are many shrink tunnel machine manufacturers, but we are one of the best choices for you.
