Frequently Asked Questions
How are soft pack tissues sealed?
Soft pack tissues are sealed using high-speed automated heat-sealing technology. Once the tissues are folded and stacked, they are wrapped in a flexible polymer film—typically polyethylene (PE) or biaxially oriented polypropylene (BOPP). Mechanical sealing bars apply a precise combination of thermal energy and pressure to the film’s edges, melting the inner layers to create a durable, airtight bond that protects the product from environmental contaminants.
Plastic wrapped facial tissue manufacturing?
Manufacturing plastic-wrapped facial tissues involves an integrated line consisting of a tissue folder, a log saw, and a soft-pack wrapping machine. Large jumbo rolls are converted into interfolded stacks, which are then fed into the wrapper. The machine wraps a continuous sheet of printed film around the stack, forming a tube. Rotating or reciprocating sealing jaws then cut and seal the ends of the pack at speeds often exceeding 100 packs per minute.
Heat sealing tissue paper packaging?
Heat sealing in tissue packaging relies on the thermoplastic nature of the outer film. Constant-heat bars or impulse sealers are calibrated to the specific melting point of the material, usually between 120°C and 180°C. Advanced sensors ensure the temperature remains consistent to prevent burning thin films while ensuring a hermetic seal. This process has largely replaced traditional cardboard adhesives due to the superior barrier properties and cost-efficiency of flexible films.
Waterproof travel tissue production?
Waterproof travel tissue packs are produced using multi-layer laminate films that incorporate high-density polyethylene (HDPE) or metallized layers for enhanced moisture resistance. During production, the “travel” size is achieved through high-compression stacking to minimize air gaps. The final perimeter seal is designed to be completely non-porous, ensuring the tissues remain dry even in humid or wet conditions, which is a significant advantage for portable hygiene products.
How to make resealable tissue packs?
Resealable packs are manufactured by integrating a labeling station into the wrapping line. A high-precision rotary die-cutter first creates a perforated or “cut-through” opening in the film. A labeling unit then applies a pressure-sensitive adhesive (PSA) sticker over the opening. The adhesive is specifically formulated to retain its tackiness through multiple uses, allowing the consumer to peel back the label to retrieve a tissue and press it back down to seal the pack.
