What is PE film coating?

Part 1: Advantages of Our PE Release Films

1.1 Factory-Backed Quality Control

We partner with ISO 9001-certified factories to ensure:

Material Consistency: Virgin-grade PE resin (e.g., Dowlex™, ExxonMobil™).

Precision Coating: Silicone coating weight tolerance ±0.2 g/m².

Testing Protocols:  Release Force: ASTM D3330 tested.  Thickness: Laser-measured (±5% tolerance).

 

1.2 Cost Efficiency

Competitive Pricing:

Standard PE films: 0.15–0.15–0.30/sqm (FOB).

Custom grades: 0.25–0.25–0.50/sqm (FOB).

Bulk Discounts: 5–8% off orders >5 tons.

 

1.3 Customization Flexibility

Thickness Options: 20–200 µm (±5%).

Width Adjustments: 100–2,000 mm (±1mm tolerance).

Specialty Coatings:

Anti-Static: Surface resistance ≤10⁹ Ω/sq.

Matte/Glossy Finish: For branding or reduced glare.

Part 2: Applications of PE Release Films

1.1 Adhesive Labels & Tapes

Use Case: Food packaging labels, medical tapes.

Requirements:

Release Force: 10–50 g/25mm for easy peeling.

Smooth Surface: ≤0.5 µm roughness for crisp printing.

 

 

2.2 Industrial Composite Layup

Use Case: Fiberglass, carbon fiber molding.

Requirements:

Heat Resistance: Withstands 80–120°C during resin curing.

Non-Reactive Surface: Prevents bonding with epoxy/polyester resins.

2.3 Hygiene & Medical Products

Use Case: Diaper backsheets, surgical drapes.

Requirements:

FDA Compliance: Safe for skin contact.

Breathability: Allows moisture vapor transmission (MVTR ≥500 g/m²/day).

2.4 Agricultural Films

Use Case: Greenhouse covers, mulch films.

Requirements:

UV Resistance: 2–3 year lifespan under sunlight.

Tear Strength: ≥30 N/cm to withstand wind stress.

 

Part 3: PE Film Classifications & Specifications

3.1 By Density

Type	Density (g/cm³)	Key Features	Best For
LDPE (Low-Density)	0.910–0.925	High flexibility, moisture-proof	Packaging, agricultural
LLDPE (Linear LDPE)	0.915–0.925	Superior puncture resistance	Heavy-duty bags, liners
HDPE (High-Density)	0.941–0.965	Rigid, chemical-resistant	Industrial containers

 

3.2 By Coating Type

Silicone-Coated PE:

Release Force: 5–200 g/25mm.

Applications: Labels, tapes, composite molding.

PE with Adhesive Layers:

Pressure-Sensitive: Acrylic or rubber-based adhesives.

Applications: Protective films, surface masking.

 

3.3 By Thickness

Thickness	Applications	Key Requirements
20–50 µm	Light packaging, disposable PPE	Tensile strength ≥20 N/cm
50–100 µm	Agricultural mulch, medical drapes	UV stability, tear resistance
100–200 µm	Industrial liners, heavy-duty bags	Puncture resistance ≥50 N/cm
