Hang-hole packaging allows products to be directly hung for display, improving shelf visibility and presentation. This packaging style is widely used in the food, daily chemical, hardware, electronics, and small consumer goods industries.

The pillow pack machines from Songben feature servo-controlled automatic hole-punching devices that operate in sync with sealing and cutting processes. Providing precise hole positioning to produce a neat and uniform overall appearance.

The flow wrapper features a modular design with flexible configuration options for various hole types, including round holes and European-style hanging holes. It also allows the hole-punching function to be disabled, enabling standard pillow pack packaging. This flexibility lets one machine support multiple packaging styles.
