Using center folded film, L bar sealers create bags around products with poly bagging. Heat Seal’s L bar sealers are built to last with a compact footprint. For our Automatic option, see the HDSA1721 Automatic L Sealer. Semi-automartic L bar standard sizes range from 15” by 15” up to 30” by 40”. Custom size options are also available. Add a shrink tunnel or heat gun to an L sealer to produce tightly shrink wrapped packages for shrink wrapping. Economical and great for creating single or multi-pack packages for sale, as an insert into another package or for shipping.
