Industrial Pallet Stretch Film (5-Layer LLDPE): Heavy-Duty Load Containment by SherkatTrade

State-of-the-Art Load Stabilization: 5-Layer Cast LLDPE Pallet Stretch Film by SherkatTrade

In modern global logistics and international freight distribution, guaranteeing the structural integrity of palletized cargo is critical to preventing transit damage, product loss, and operational downtime. Pallets carrying heavy woven PP sacks, paper cement bags, chemical drums, or fragile corrugated boxes are constantly exposed to horizontal inertial forces, vibration, and moisture during road and ocean transport. SherkatTrade's Industrial 5-Layer Cast Pallet Stretch Film represents the benchmark in load containment engineering, delivering unmatched holding force, crystal-clear optics, and industry-leading stretchability.

Manufactured in our advanced polymer processing facility in Isfahan, our stretch films utilize 100% virgin metallocene linear low-density polyethylene (mLLDPE/C6/C8) polymers processed on high-speed multi-layer cast extrusion lines. This molecularly optimized formulation provides extraordinary tensile elongation up to 400%, allowing warehousing facilities and automated packaging lines to wrap more pallets per kilogram of film while drastically slashing overall packaging expenses.

Technical Specifications & Engineering Standards (2026 Edition)

Every production batch is rigorously tested according to ASTM and ISO packaging standards to guarantee maximum pallet security:

• Polymer Architecture: 5-layer co-extruded film combining high-performance cast linear low-density polyethylene (LLDPE) and metallocene plastomers.
• Nominal Thickness: 23 Microns standard (Custom engineered options available in 17, 20, 25, 30, and 35 microns).
• Standard Roll Width: 500 mm (20 inches) standard; custom slit widths from 100 mm up to 1000 mm available on request.
• Roll Configurations:
  • Hand Application Rolls (Manual): Gross weight 2.5 kg to 3.5 kg, ergonomic lightweight kraft core for operator comfort.
  • Machine Application Rolls (Automatic): Gross weight 12 kg to 16 kg, heavy-duty crush-resistant 3-inch (76 mm) cardboard cores designed for high-speed turntable and rotary arm wrappers.
• Practical Elongation Rate:
  • Hand Stretch Film: 150% to 200% manual extension without premature snapping.
  • Machine Power Pre-Stretch: 250% to 380% with high elastic memory and tension retention.
• Puncture & Tear Resistance: Dart Drop Impact resistance exceeding 250 grams per ASTM D1709, preventing rips from sharp wooden pallet edges or sack corners.
• Cling Technology: Differential One-Side Cling (Smooth slick outer surface to prevent pallet-to-pallet snagging in freight trailers, with high-tack inner cling for firm cargo adhesion).
• Ultimate Tensile Strength: Over 38 MPa in Machine Direction (MD) and 32 MPa in Transverse Direction (TD) conforming to ASTM D882.
• Optical Clarity & Gloss: >92% light transmittance, ensuring instantaneous barcode scanning, RFID reading, and pristine export inventory presentation.
• Weather & UV Shielding: Optional high-grade HALS UV stabilization for extended outdoor storage in harsh Middle Eastern port conditions up to 12 months.

Key Commercial & Operational Advantages of SherkatTrade Stretch Film

1. 30% to 50% Reduction in Packaging Material Weight

Thanks to high-yield 5-layer cast metallocene technology, our stretch film achieves greater load containment at thinner gauges compared to conventional 3-layer blown films. Wrapping a standard 1200x1000mm pallet carrying 1.5 tons of cargo requires merely 250g to 300g of film, significantly cutting consumable costs.

2. Advanced One-Side Cling (Frictionless Logistics)

Traditional generic stretch wraps suffer from bilateral stickiness, causing neighboring pallets in freight trucks or shipping containers to adhere together and tear during forklift unloading. SherkatTrade stretch wrap features an engineered non-cling exterior that glides smoothly while maintaining ultra-secure internal adhesion.

3. Zero-Relaxation Elastic Retention

Inferior films tend to stretch and loosen after 48 hours of warehouse storage, leading to pallet leaning. Our films are formulated with high molecular weight elastomeric chains that retain their compressive tension over prolonged sea voyages and temperature fluctuations.

4. Dust-Free, Odorless, and Food-Safe Compliance

Produced in clean manufacturing environments without mineral fillers or recycled off-grade polymers, complying with international sanitary requirements for dry food and pharmaceutical secondary packaging.

Expert Guidance: Manual Hand Stretch vs. Automated Machine Wrap

• When to Select Hand Stretch Wrap:
  Ideal for warehouses, distribution hubs, and small-scale operations wrapping under 40 pallets per day. The lightweight 2.5kg to 3.5kg rolls allow operators to move quickly and securely wrap irregular pallet profiles without requiring machinery investments.

• When to Select Machine Power Stretch Wrap:
  For continuous automated bottling, cement, grain, and chemical packing plants wrapping over 50 pallets per shift. Installing high-yield machine rolls on pre-stretch wrapping machinery optimizes film consumption down to gram-level precision while finishing each pallet in under 60 seconds.

Frequently Asked Questions by Logistics & Procurement Managers (FAQ)

What is the recommended film thickness for heavy 50kg cement or grain sack pallets?

For high-density pallet stacks weighing between 1,000 kg and 1,800 kg, we strongly recommend a 23-micron or 25-micron cast film applied with a 250% power pre-stretch ratio to guarantee complete load cohesion under emergency braking conditions.

What are the minimum order quantities (MOQ) and lead times for export shipments?

SherkatTrade maintains extensive warehouse inventories in Isfahan. We fulfill orders ranging from single pallet pallets up to full container loads (20ft and 40ft FCL) with rapid dispatch within 3 to 7 business days.

Can you provide UV-stabilized stretch film for outdoor yard storage?

Yes, for cargo exposed to direct solar radiation and high ambient UV levels in ports and open mining sites, we incorporate premium Hindered Amine Light Stabilizers (HALS) offering 6 to 12 months of outdoor photolytic stability.
