Who This Is For

Warehouse operations managers, logistics coordinators, and procurement specialists who stabilize palletized loads for distribution or export. This includes food and beverage distributors, manufacturing plants, third-party logistics providers, and export trading companies.

Shrink wrap film is one of the most cost-effective methods to secure pallet loads, protect against moisture and dust, and prevent damage during handling and transit.

The Recommended Product: Shrink Wrap Film for Pallet Wrapping

Shrink wrap film is a thermoplastic film that contracts when heated, forming a tight protective envelope around palletized loads. Shrink film delivers more dramatic contraction (up to 50%) than stretch film, creating a snugger, more uniform fit — ideal when maximum load stability is required.

For pallet stabilization, the industry standard is cast LLDPE (linear low-density polyethylene) shrink film, which combines high puncture resistance, excellent clarity, and strong self-adhesion at a competitive per-pallet cost.

Key Specifications

| Core Size | 3" (76mm) standard; 1.5" for certain dispensers |

| Adhesion | Low, medium, or high tack |

Cast vs Blown Shrink Film

Cast Shrink Film (Recommended)

Cast film is extruded through a flat die onto a chilled roll, creating uniform thickness and excellent clarity.

| Feature | Advantage |

|---|---|

| Thickness tolerance | ±2µ — consistent wrap, no weak spots |

| Clarity | 85–90% transmittance — identify loads without unwrapping |

| Puncture resistance | Superior for sharp corners and edges |

| Tear propagation | Low — tears stop at edges |

| Noise | Quiet unwind — better warehouse environment |

| Gauge | Thinner at 15–23µ — more meters per roll |

Blown Shrink Film

| Feature | Consideration |

|---|---|

| Thickness tolerance | ±5–10µ — less consistent |

| Clarity | 70–80% transmittance — slightly hazy |

| Tear strength | Higher in machine direction but tears propagate more |

| Gauge | Typically 20–40µ — fewer meters per roll |

| Best for | Heavy, bulky loads needing thick-film puncture resistance |

Recommendation

For most applications, cast LLDPE at 17–20µ provides the best balance of load stability, coverage efficiency, and cost-per-pallet. Reserve blown film for heavy irregular loads where puncture resistance is paramount.

Cost Efficiency Metrics

| Parameter | Cast 20µ × 500mm × 4,000m | Blown 25µ × 500mm × 3,000m |

|---|---|---|

| Coverage per roll | ~80–120 pallets | ~55–85 pallets |

| Cost per wrapped pallet | ~$3.50–$5.50 | ~$4.50–$7.00 |

| Film waste | Low | Moderate |

| Storage footprint | 25% smaller rolls | Bulkier |

Properly wrapped pallet loads reduce damage claims by 40–60% for dry freight and moisture-related damage by 90%+ for ocean or outdoor exposure.

Ideal Applications

| Application | Recommended Film | Notes |

|---|---|---|

| Dry freight pallets (500–1,000 kg) | 17–20µ cast, medium tack | Standard for retail distribution |

| Heavy industrial loads (1,000–2,000 kg) | 20–25µ cast, high tack | Add corner boards |

| Food & beverage | 20µ cast, FDA-compliant | Food-safe LLDPE |

| Export / ocean freight | 20–23µ cast, UV-stabilized | 90-day UV protection |

| Cold storage & frozen | 20–23µ cast, low-temp | Flexible at -40°C |

| High-value retail | 17–20µ cast, printed | Brand logos, tamper-evident |

Supplier Quote Checklist

  1. Resin specification: Verify LLDPE grade and virgin vs recycled content.
  2. Thickness tolerance: ±2µ (cast) or document blown tolerance.
  3. Tack force data: Medium tack (~200–350 gf) for most apps; high tack (>350 gf) for heavy loads.
  4. Roll dimensional accuracy: Width, core diameter, and roll length must match dispenser specs.
  5. Elongation at break: Should exceed 400% for load-hugging capability.
  6. Food compliance: FDA 21 CFR 177.1520 or EU 10/2011 for food contact.
  7. Sample policy: Order 2–3 sample rolls in 17µ, 20µ, 23µ and test on actual pallets.
  8. MOQ and lead time: 500 rolls standard clear; 1,000–2,000 for custom print. Lead time 15–25 days.
