In modern tertiary packaging lines—spanning high-volume beverage bottling plants, canning operations, ceramic tile manufacturing, brickyards, and pharmaceutical logistics—unitizing goods securely into tight, rigid multipacks requires high-performance thermal shrink films. SherkatTrade Industrial 3-Layer Co-Extruded PE Shrink Film Rolls are manufactured utilizing advanced multi-layer blown film extrusion technology, combining premium virgin Low-Density Polyethylene (LDPE 0075) with performance-enhancing metallocene linear resins (mLLDPE) to deliver peak bundling reliability.
When exposed to heat in radiant, convection, or gas-fired shrink tunnels, our films contract with precisely calibrated biaxial ratios—Machine Direction (MD: 60-75%) and Transverse Direction (TD: 15-25%). This creates a continuous, high-tension polymer skin around the payload that locks bottles, cans, and cartons into stable monolithic units, eliminating package deformation and corner "dog-ears" during transit and forklift handling.

| Industry & End-User Sector | Recommended Gauge & Width | Packaged Product | Strategic Commercial Advantage |
|---|---|---|---|
| Beverage & Bottling Plants | 45 - 70 µm (Width: 50 - 65 cm) | 6-pack & 12-pack PET bottles, cans | Tight bullseye openings, rigid pack holding, and zero pack slackening |
| Ceramic Tiles & Building Bricks | 80 - 130 µm (Width: 80 - 120 cm) | Cartoned tiles, paving stones, blocks | Weatherproof barrier protecting cartons from moisture and rain damage |
| Canned Foods & Dairy Products | 50 - 80 µm (Width: 40 - 70 cm) | Canned tomato paste, tuna, milk cartons | Hygienic isolation, dust prevention, and clean wholesale retail packaging |
| Pharmaceutical & Cosmetic Master Packs | 35 - 55 µm (Width: 30 - 60 cm) | Medicine cartons, personal care multipacks | Tamper-evident protection, barcode readability, and high optical gloss |
| Heavy-Duty Export Pallet Securing | 120 - 180 µm (Width: 100 - 150 cm) | Palletized bagged cement, resin pellets | Cost-effective monolithic pallet stabilization replacing stretch wrapping |
Thanks to the metallocene polymer matrix, SherkatTrade shrink films remain elastic during the oven heating phase. They draw tightly over sharp crate and tray corners without thinning out, puncturing, or tearing.
The film edges weld instantaneously in continuous automated sealing bars, forming unbreakable seam lines that maintain their structural integrity even when packs are picked up while hot.
A wide operating temperature window (140°C - 180°C) allows plant managers to accelerate conveyor line speeds by up to 20% while reducing thermal tunnel kilowatt consumption.
We offer custom flexographic printing using heat-resistant inks that do not distort, fade, or bleed when passed through high-temperature shrink ovens.
The required film width is calculated as: Pack Height + Pack Width + 10 cm free edge allowance. For light multi-packs, 45-60 microns is standard; for medium bottles and cans, 70-90 microns; and for pallet securing, 100-150 microns is recommended.
Yes. Our polymer blend is formulated to perform seamlessly across all industrial heating methods, including continuous electric conveyor tunnels, chamber machines, and manual gas heat guns.
The standard MOQ is 500 kg for standard width rolls and 1 metric ton for custom dimensions or printed reels. Rolls are wound on heavy-duty 76 mm (3-inch) paper cores, wrapped in protective film, and dispatched directly from our Isfahan plant.
Yes. All our shrink film formulations contain calibrated food-grade anti-static additives to prevent electrostatic dust accumulation during warehouse storage.
