4. Production Technology

1. Biaxial Stretching Process

Tradsark adopts internationally advanced simultaneous and sequential stretching technologies, ensuring stable film thickness, high uniformity, and excellent optical properties.

Sequential Stretching (Mainstream Technology)

• Stretching → MD → TD

• Advantages: cost-effective, consistent quality, suitable for general high-barrier packaging

Simultaneous Stretching (High-End Technology)

• MD & TD stretched at the same time

• Advantages:

  • Ultra-low shrinkage

  • Best film flatness

  • Superior clarity

  • Better strength balance
    Used in high-performance applications.

2.PA6 Resin & Copolyamides

• Low moisture & low monomer content

• Stable extrusion

• Excellent barrier & thermoformability

• Available with EVOH co-extrusion for ultra-high barrier

3. Film Structures Available

• Mono-layer PA film

• Co-extruded PA/PA

• PA/EVOH/PA (high barrier)

• PA with customized functional coatings

5. Applications
