By implementing steps including tube forming via tuber machine with inline printing, valve bottom bag opening, folding, gluing, compacting and finally form a complete valve bag, even inner or outside paper reinforcement within a fully automatic process, this machine can effectively save labor costs. Most stable valve forming process and special bag counting function and bag collection system greatly improve sack kraft bags efficiency. Thanks to perfect technologies and fast production speed, this machine can produce various multi-layers sack kraft paper bags with high quality.
The machine has optional of inline 2-4 colors inline printing, upto 4 layers paper and 1PE for all types of multi-layers sack kraft paper bags.
