Unitized Cargo Stabilization

-- Steady & Reliable Manufacturer --

Cargo Unitization & Containment Mechanics

Unitized cargo stabilization materials—comprising multi-layer cast stretch films, high-retention stretch hoods, and heavy-duty PET strapping—are engineered to bind individual packages, cartons, or containers into a unified load structure. These materials generate sustained load containment force, preventing pallet leaning, layer shifting, and structural collapsed loads during transit.

Multi-layer co-extrusion technology arranges LLDPE resin layers to maximize puncture resistance, tear propagation resistance, and elastic recovery strain, maintaining clamping force over long-distance multi-modal transport.

Cast Extrusion & Stretch Testing

Zhejiang Geruite Packaging Materials Co., Ltd. operates multi-layer cast stretch film extrusion machinery capable of producing high-performance machine film and hand wrap. Inline thickness gauges ensure consistent gauge distribution across wide-web rolls.

Laboratory verification includes pre-stretch ratio testing (up to 300%), dart drop impact resistance evaluation, and containment force retention testing using electronic load-cell sensors.

Target Application Fields

  • High-Bay Automated Warehousing: Secures stacked pallet loads for safe movement inside automated storage systems (ASRS).
  • Intermodal Freight & Container Shipping: Maintains load stability against sea wave movement and road transport vibration.
  • Beverage & Bottled Goods Logistics: Stabilizes heavy, high-center-of-gravity liquid cargo packages during distribution.
  • Bagged Chemical & Fertilizer Pallets: Prevents bag movement and corner bulging on multi-tiered pallet stacks.

Core Functional Characteristics

  • High Pre-Stretch Performance: Reduces material consumption per pallet while increasing load clamping force.
  • Puncture Resistance: Resists tearing from sharp wooden pallet corners and protruding box edges.
  • High Optical Clarity: Allows effortless barcode scanning and shipping label reading through film layers.
  • No-Tack Exterior Layer: Prevents adjacent wrapped pallets from sticking together during truck loading.

Frequently Asked Questions

  • Q: What pre-stretch ratio should be selected for high-speed automatic wrapping machines?
  • A: High-performance 23–25 μm cast machine films support pre-stretch ratios between 250% and 300%, maximizing yield per roll without film breaking.
  • Q: Does stretch film protect pallets against rain during outdoor loading?
  • A: Standard stretch wrapping seals side walls against rain; adding a top cover sheet prior to wrapping creates a water-resistant sealed pallet top.

Material Selection Guide

Select hand stretch film (15–20 μm) for manual warehouse wrapping under 30 pallets per day. Choose high-pre-stretch machine film (20–35 μm) for automated turntable and rotary arm wrapping equipment operating on high-volume production packaging lines.
