Details Description

Stretch Film for Packing Plywood Cases and Cargoes: 

1. Material Composition and Types

Stretch films used in industrial packaging (especially for plywood cases and heavy cargoes) are primarily made from polyethylene (PE) polymers, with key types including:

Type

Material Characteristics

Application Scenarios

LLDPE (Linear Low-Density PE)

High tensile strength, excellent puncture resistance, and superior stretchability.

Heavy-duty packaging for plywood cases, metal parts, and bulky cargo.

LDPE (Low-Density PE)

Softer texture with good clarity and self-adhesion.

General-purpose wrapping for lighter cargoes or manual application.

MDPE (Medium-Density PE)

Balances stiffness and flexibility, suitable for semi-heavy loads.

Intermediate-weight goods like machinery components.

Composite Films

Multi-layer structures (e.g., LLDPE + LDPE) for enhanced performance (e.g., UV resistance).

Outdoor storage or long-distance transportation requiring weather protection.

2. Key Features for Plywood Case Packaging

High Tensile Strength: Ensures tight wrapping to prevent cargo shifting during transit (e.g., tensile strength ≥ 20 MPa for LLDPE films).

Puncture Resistance: Resists tears from sharp edges of plywood or protruding cargo parts (e.g., Elmendorf tear strength ≥ 200 g).

Self-Adhesion: Minimizes the need for additional tapes by adhering to itself, securing loads effectively.

Moisture & Dust Protection: Acts as a barrier against humidity and contaminants, preserving the surface of plywood and goods.

UV Stability (Optional): Specialized films with UV inhibitors prevent degradation from sunlight during outdoor storage.

How Stretch Film Solves It

Plywood Cases

Heavy weight, potential edge damage, moisture absorption.

Tight wrapping distributes weight evenly; puncture-resistant films protect edges; moisture barrier preserves wood quality.

Metal Machinery

Sharp corners, rust risk from condensation.

Thick-gauge films (e.g., 20–30 μm) cushion corners; airtight wrapping reduces oxidation.

Palletized Goods

Load stability during forklift handling or shipping.

High stretchability (up to 300% elongation) allows secure bundling, minimizing pallet collapse.

Fragile Equipment

Vibration and impact during transport.

Elastic film tension absorbs shocks, while multiple layers provide cushioning.

4. Technical Parameters and Selection Tips

Thickness:

Manual stretch film: 12–25 μm (suitable for small batches, easy to handle).

Machine-grade film: 20–50 μm (higher strength for automated pallet wrapping).

Stretch Ratio:

Standard films: 150–200% stretch; high-performance films: 250–300% stretch (reduces material usage by up to 50%).

Gauge Uniformity: Ensures consistent tension; look for films with ≤ 5% thickness variation.

Roll Dimensions: Common widths: 300–500 mm; roll lengths: 500–3000 m (adjust based on pallet size and wrapping patterns).

5. Environmental Considerations

Recyclability: Most PE stretch films are recyclable; look for films with recycling codes (e.g., Resin Code #4).

Biodegradable Options: Starch-based or oxo-biodegradable films are available for eco-conscious applications (though less common in heavy-duty use).

Thin-Gauge Innovation: Thinner films with equivalent strength reduce plastic waste (e.g., 15 μm films replacing 25 μm films).
