Chain pack packaging connects multiple individual packs at fixed intervals and is commonly used for promotional packs, combination packs, and retail-ready displays. This packaging format facilitates shelf display and sales while reducing film consumption and improving production efficiency. This is an efficient packaging solution widely used in food, daily chemical, medical, small commodities, and other industries.

Songben horizontal packaging machines utilize multiple servo control systems, ensuring accurate synchronization of film feeding, product pushing, and bag sealing and cutting. The number and length of connected packs can be adjusted easily based on needs, providing smooth and consistent sealing. The flow wrapper supports seamless switching between standard pillow packs and chain packs, letting a single machine manage different applications to meet flexible production needs and varied market demands.
