In‑line zipper application for premium, resealable cheese packaging with reduced material cost
The Vertical Resealable Packaging Machine is an integrated vertical form‑fill‑seal (VFFS) system designed to apply, cut, and seal zipper‑type closure profiles in‑line directly onto flat packaging film. This configuration eliminates the need for costly pre‑made resealable bags, reducing overall packaging material costs by up to 30%.
The system enhances the standard VFFS cycle by incorporating a zipper applicator module upstream of the forming shoulder. The male and female zipper profiles are unwound from reels and continuously heat‑sealed or ultrasonically welded to the flat film before bag formation. The film, now equipped with the closure profile, is then formed, filled, and sealed in a single continuous process.
To preserve product protection, the cross‑jaw sealing system is specifically engineered to hermetically seal the zipper ends at the transverse seals. This design ensures that, although the package is resealable, the original Modified Atmosphere Packaging (MAP) remains intact until the consumer's first opening, maintaining freshness and shelf life.
This solution enables producers to transform standard cheese formats—such as shredded cheese—into high‑value, consumer‑friendly products with improved convenience and reduced operating investment.
