ROTYPACK Doypack Packaging Machine: Automatic Operation Principle and Industry Application of Pre-made Pouch Packaging Machine

The ROTYPACK doypack packaging machine is a common automatic bag-feeding packaging device in the industry. It completes the whole packaging process with pre-made stand-up pouches without roll film bag-making procedures, simplifying workshop production and reducing equipment maintenance difficulty. Adopting a multi-station cyclic operation mode, the machine automatically realizes bag picking, bag opening, positioning, filling, heat sealing, exhausting and discharging, supporting mass production in food, condiment, agricultural and pet food industries.

               
The machine is compatible with various material forms including granules, powder, liquid, paste and sauce, realizing quantitative filling with matching weighing, screw and piston metering modules. It supports multiple common pre-made pouch types such as ordinary stand-up pouches, zipper pouches and spout pouches. Product specification switching only requires parameter adjustment and simple tooling replacement to reduce downtime and support multi-product joint production.

All material contact components are made of food-grade stainless steel with detachable structures for daily cleaning and disinfection, meeting food clean production standards. The well-structured electric control system ensures stable operation and simple operation logic. The machine can work independently or connect with upstream and downstream equipment to form a complete automatic packaging line for production workshops of different scales.
