APET sheet roll

Best Choice

APET (Virgin APET | Customizable corona treatment | Crystal clear)

We exclusively recommend APET for folding box and printing applications due to the critical balance of optical, physical, and processing requirements. RPET is not recommended for this application.

  • Crystal-clear transparency — premium product display
  • Superior gel/particle control — critical for clean printing surface
  • Consistent clarity — no batch-to-batch color variation
  • Optimized slip properties — prevents scratching during die-cutting
  • Smooth surface finish — ensures clean print reproduction
  • Customizable corona treatment (38-52 dyne/cm) for various printing methods
  • Excellent folding performance — crisp creases without whitening
  • Good die-cutting precision
  • Compatible with UV printing, silk screen, offset printing

Why Not RPET?

  • Critical Limitations for Printing Applications
  • Batch-to-batch color inconsistency — affects brand image
  • Higher gel/particle count — interferes with printing quality
  • Variable transparency — inconsistent product presentation
  • Unpredictable surface properties — affects ink adhesion

For folding box and printing applications where visual perfection and brand consistency are paramount, virgin APET is the only recommended solution.

Recommended Specs: 0.25–0.5 mm
Main applications: Folding Gift Boxes, Window Display Boxes, Printed Rigid Boxes.

Corona Treatment Guide

Why Corona Treatment Matters:
Corona treatment increases surface energy, ensuring stronger ink and adhesive bonding for improved print quality, durability, and downstream processing performance.

Printing Method Recommended Corona Typical Application
Offset Printing 38–42 dyne/cm Standard commercial printing
UV Printing 42–48 dyne/cm High-quality graphics
Silk Screen 40–45 dyne/cm Thick ink deposits
Hot Stamping 40–46 dyne/cm Metallic foil application
Adhesive Lamination 42–48 dyne/cm Bonding with paper or film
