It dictates the final shape, size, and overall structure of the package, directly impacting product containment, presentation, and downstream handling. A thorough understanding of this process is essential for optimizing machine performance and achieving desired packaging outcomes.
-
Film Unwinding and Shaping
The process begins with the unwinding of a continuous roll of flexible packaging film. This film is then guided and shaped into a tubular form using a forming collar or tube. Precise control over film tension and alignment is crucial for consistent package dimensions and preventing wrinkles or deformities. The material used, whether it be polyethylene, polypropylene, or a laminate, influences the formability and final characteristics of the package.
-
Longitudinal Sealing
Once the film is shaped into a tube, a longitudinal seal is created along its length, transforming it into a continuous pouch. This seal, typically formed by heated elements, ensures the integrity of the package sides and prevents leakage. The strength and reliability of this seal are paramount for maintaining product quality and preventing contamination.
-
Cross Sealing and Cutting
Individual packages are then formed by transverse seals, created perpendicular to the longitudinal seal. These seals define the length of each package and are typically followed by a cutting operation that separates the individual units. Accurate control of sealing temperature, pressure, and dwell time is critical for creating strong, hermetic seals and clean cuts.
