Heat Seal HDX250A Overview
The Heat Seal HDX250A is an automatic L-bar sealer and shrink tunnel system for packaging printed product, kits and media at production volume. Mid-State Litho is an authorized Heat Seal dealer with factory-trained service and a supply of film and parts across Michigan and the Great Lakes.
L-Bar Sealer Plus Shrink Tunnel
The HDX250A combines two steps into one inline system. The L-bar sealer wraps and seals the film pouch around the product, and the heat tunnel then shrinks that film tight to the package for a clean, finished wrap. It suits printed product, kits, media and retail-ready packages, and runs standard shrink film. Our team confirms the recommended film type and maximum package size for your work against the current Heat Seal specification.
