Cold Seal Packaging Film

Engineered specifically for heat-sensitive confectionery, nutrition bars, and frozen novelties requiring lightning-fast packaging speeds. Utilizing food-grade, water-based natural or synthetic cohesive adhesives that bond securely under light pressure alone—completely eliminating sealing heat to protect meltable contents while achieving line speeds up to 1,500 packs per minute.

Manufactured in compliance with US FDA 21 CFR 175.105 (Adhesives) and EU food-contact framework regulations, produced in BRCGS and ISO 22000 certified clean-room environments.

Suitable for
Chocolate & Pralines
Energy & Nutrition Bars
Ice Cream & Frozen
Bakery & Biscuits
Medical Packaging

Heatless high-speed sealing rollstock

Product Overview

Traditional heat-seal films transfer ambient thermal energy through the film layer, risking cocoa butter melting, thermal degradation, and line downtime during equipment stops. Our cold seal film structures apply pattern-applied cohesive latex/acrylic adhesives exclusively to designated perimeter seal zones on the inner sealant web, paired with a high-performance silicone release lacquer or reverse-wound release layer on the exterior to prevent roll blocking. Designed for high-speed Horizontal Form-Fill-Seal (HFFS / Flow-Wrap) machinery, our films ensure hermetic seal closure, zero thermal distortion, and clean consumer fiber tear.

Zero thermal transfer & hermetic sealing

Key Features

  • 100% heat-free contact protection：Seals instantly under mechanical jaw pressure without thermal heat transfer, completely preventing chocolate edge melting, fat bloom, ice cream melting, and wrapper deformation.
  • Ultra-high-speed flow-wrap efficiency：Eliminates machine dwell-time and cooling jaw requirements, boosting packaging speeds on modern flow-wrapping lines by 30% to 50% compared to standard thermal sealing webs.
  • Zero-blocking release engineering：Engineered with calibrated anti-block release varnishes to prevent adhesive transfer onto the printed outer surface during high-tension roll winding and storage.

Options & Features

Configure barrier layers, adhesive chemistry, surface release lacquers, and precise pattern registrations for seamless flow-wrap conversion.

01

Barrier Substrates & Base Webs

  • Metallized BOPP barrier (BOPP/VMBOPP)：Premium barrier against moisture vapor, light, and oxygen; the industry benchmark for chocolate bars.
  • White cavitated opaque BOPP：High-yield pearlized opaque film offering low density, light blocking, and an immaculate clean canvas.
  • Natural paper / cold seal lamination：Eco-conscious tactile paper outer layer with targeted cold seal adhesive pattern for artisan snack wraps.
  • Recyclable mono-PP cold seal：Fully circular mono-material polyolefin structure meeting EU mechanical recycling guidelines.
02

Adhesive Chemistry & Pattern Precision

  • Natural rubber cohesive：High green strength and instant grab under low jaw pressure; ideal for standard snack lines.
  • Allergen-free synthetic adhesives：100% synthetic latex-free formulations complying with strict clean-label medical and food demands.
  • High-precision gravure pattern coating：Adhesive applied solely to longitudinal and cross-seal seams, saving up to 60% adhesive usage.
  • Controlled seal strength formulations：Tunable peel strength from soft, easy-open peelable closures to high-integrity fiber-tear bonds.
03

Surface Protection & Machine Optics

  • Full-coverage anti-block varnishes：Prevents adhesive migration onto the exterior brand artwork during master roll rewinding and slitting.
  • High-slip exterior additives：Dynamic coefficient of friction (COF < 0.25) ensuring snag-free web feeding through forming collars.
  • High-contrast eye marks：Precision-printed registration marks for accurate pitch cutoffs on high-speed servo-driven cutters.
  • Matte & gloss registered inks：Contrast finishes highlighting brand graphics without compromising the protective release lacquer.
