In outdoor storage yards, intermodal sea container shipping, and flatbed truck transit, securing heavy palletized cargo—such as refractory bricks, ceramic tiles, 50kg bagged cement and gypsum, glass containers, and heavy industrial machinery—demands structural load containment far superior to conventional stretch wrap. SherkatTrade Heavy-Duty 5-Sided Thermal PE Pallet Shrink Bags and Continuous Perforated Roll Covers are manufactured using heavy-gauge Low-Density Polyethylene (LDPE 0075) reinforced with metallocene resins (mLLDPE) to form a seamless, waterproof, monolithic polymer shield around all five exposed pallet faces.
Supplied as pre-formed gusseted covers or tear-off perforated rolls, these bags easily slip over the loaded pallet like a hood. When heat is applied using automated gas shrink columns or portable propane gas shrink guns (such as Ripack or Shrinkfast), the film contracts with powerful cross-directional tension, curling under the wooden pallet baseboards. This process locks the payload and pallet together into an impenetrable, rigid block that withstands extreme road vibrations and maritime storms without shifting, tilting, or water penetration.
| Technical Parameter | Standard Production Range | Test Standard | Operational & Transit Security Advantage |
|---|---|---|---|
| Polymer Resin Architecture | Co-Ex 3-Layer (Heavy LDPE 0075 + mLLDPE Blend) | ASTM D1238 | Exceptional tensile strength, puncture resistance, and broad thermal heating window |
| Film Thickness Range | 80 to 250 microns (320 to 1000 gauge) | ISO 4593 | Extreme tear and puncture resistance against sharp brick and stone corners |
| Open Perimeter / Width | 1000 mm to 5500 mm (M-Fold Gusseted) | Tolerance ±5 mm | Full coverage for EUR pallets (1200x800), Industrial (1200x1000), and custom sizes |
| Liner Bag Length / Height | 100 cm to 300 cm | Mill Standard | 30 cm bottom skirt allowance ensuring tight under-pallet tucking and mechanical locking |
| Machine Direction Shrink (MD) | 50% to 65% under heat gun | ASTM D2732 | Powerful vertical clamping force pulling the load downward against the wood pallet |
| Transverse Direction Shrink (TD) | 45% to 60% under heat gun | ASTM D2732 | High horizontal hoop tension preventing pallet layers from shifting or bulging |
| Outdoor UV Weatherability | 12 to 24 months outdoor exposure | ASTM G154 | Swiss-formulated HALS UV stabilizers protecting cargo in tropical seaport terminals |
| Yield Tensile Strength | MD ≥ 26 MPa / TD ≥ 25 MPa | ASTM D882 | Safely stabilizes heavy pallet payloads from 500 kg up to 2500 kg without rupture |
| Dart Drop Impact Resistance | > 650 grams at 120 microns thickness | ASTM D1709 | High resistance to forklift fork scuffs, strap chafing, and transit abrasion |
| Color & Opacity Options | Clear Transparent, Opaque Black, Solar White | Industrial Grade | Black prevents cargo pilferage; white reflects solar heat to keep goods cool |
| Industry & End-User Sector | Recommended Pallet Dimensions | Thickness | Packaged Product Load |
|---|---|---|---|
| Clay Bricks, Pavers & Refractories | 100×100 cm / 120×100 cm | 120 - 180 µm | Palletized facing bricks, refractory blocks, tiles, and travertine |
| Cement, Gypsum & Dry Mortars | 120×100 cm (Height: 140 cm) | 100 - 150 µm | 50 kg multi-wall valve bags of Portland cement, lime, and plaster |
| Petrochemicals & Bulk Fertilizers | 120×120 cm (Standard CP3 Pallet) | 120 - 160 µm | 25 kg bags of Urea fertilizer, polymer resins, and sulfur granules |
| Glass Bottle & Metal Can Plants | 120×100 cm (Height: 200 cm) | 90 - 130 µm | Multi-tiered bulk pallets of empty glass bottles and beverage cans |
| Industrial Equipment & Generators | Oversized custom dimensions up to 3m | 160 - 250 µm | Electric transformers, pumps, machine tools, and crated machinery |
When shrunk with a gas gun or heat frame, the bottom skirt automatically curls tightly around the underside of the wooden pallet stringers, creating a unified mechanical bond that eliminates the need for steel or PET strapping.
Unlike stretch film that has open seam overlaps and permeable top sheets, a 5-sided shrink hood forms a seamless protective envelope that allows outdoor yard storage without tarpaulins.
Our metallocene-enhanced polymer formulation offers an expansive thermal processing window, preventing localized blow-outs, pinholes, or burning when operators use handheld propane torches.
We offer custom flexographic printing of handling pictograms (forklift arrows, fragile symbols, center of gravity), corporate branding, and scannable tracking barcodes.
Bag Width = (Pallet Width + 10 cm); Gusset Depth = (Pallet Length + 10 cm); Bag Length = (Cargo Height + Half Pallet Width + 30 cm bottom skirt for under-pallet lock).
No. Most industrial users utilize portable handheld propane gas shrink guns (such as Ripack 3000 or Shrinkfast 998), which take less than 2 minutes to shrink a full pallet load.
Pallet shrink covers are up to 5 times thicker, provide 100% waterproof protection, feature UV stability for outdoor storage, and provide rigid anti-tilt stabilization for heavy loads.
The standard MOQ is 500 kg. Covers can be supplied individually folded in bundles of 10 or 20 bags inside protective outer sacks, or wound on continuous perforated rolls.
