Transform a commodity product into a superior brand reference. The resealable capability protects your product from oxidation in the customer's refrigerator, strengthening brand loyalty and reducing household food waste.
This unit modifies the standard VFFS cycle by integrating a zipper applicator module before the forming shoulder.
The closure profile (male/female) is unwound and continuously heat-sealed or ultrasonically welded onto the flat film.
The film with the integrated zipper then passes through the forming tube where filling takes place.
The transverse jaw system is specifically designed to hermetically crush-seal the zipper ends, guaranteeing that, even though the package is resealable, the original Modified Atmosphere Packaging (MAP) remains intact until the consumer's first opening.
•In-Line Zipper Application: Drastically reduces packaging material cost (up to 30%) by using standard film reels and separate zipper reels, instead of purchasing pre-formed bags or third-party pre-applied zipper films.
•Sealing Jaws with Zipper Profile: Ensures total hermeticity at package corners (where the zipper crosses the lateral seal). This is critical to prevent inert gas leakage in products packaged with Modified Atmosphere (MAP).
•Operational Flexibility (With/Without Zipper): The system allows the applicator module to be deactivated to run institutional or economy formats without closure, maximizing asset utilization across different market segments (Retail vs. Food Service).
•Perceived Value and Shelf Differentiation: In saturated categories such as shredded or frozen cheeses, packaging functionality is the decisive purchase factor. Consumers prefer to pay a premium for storage convenience without needing to transfer the product.
•Robust Stainless Steel Construction: Maintains the sanitary standards required for dairy products, allowing deep cleaning without risk of corrosion in the closure application mechanisms.
