What are the differences between PET and PETG decorative films?
As eco-friendly veneers replace traditional PVC materials for high-end custom furniture, PET decorative film and PETG decorative film have become mainstream substrates. SAINO launched a technical training document comparing PET FILM and PETG FILM, offering clear material selection standards for cabinet factories and laminators.
PET decorative film and PETG decorative film share core eco-friendly merits.
Both PET FILM and PETG FILM are food-grade, odorless and formaldehyde-free, suitable for cabinet doors and decorative panels. Flat lamination and thermal composite processes work well for PET FILM and PETG FILM without equipment upgrades.
SAINO classifies finished products by substrate.
PET FILM covers transparent scratch-resistant, metal brushed, stone composite and mirror varieties; stable heat resistance and high hardness make PET decorative film ideal for flat high-gloss panels. PETG FILM includes solid-color, wood grain and matte textured styles. Great color masterbatch compatibility lets PETG decorative film excel in full-house custom cabinet production.
Structural differences separate PET FILM and PETG FILM fundamentally.
PET FILM is crystalline polyethylene terephthalate stable up to 140°C with coating hardness of 3H–6H, so PET decorative film suits hot-processing flat surfaces. PETG FILM is amorphous modified PET softening at 70°C with around 2H hardness, yet it features outstanding flexibility. Rigid PET FILM easily develops white cracks when bent, restricting PET decorative film from curved wrapping. PETG FILM creates no whitened edges after cutting, making PETG decorative film perfect for cabinet edge banding. PET FILM uses bidirectional stretching with lower costs, while extruded PETG FILM costs slightly more but cuts solid-film waste rates.
SAINO provides targeted application advice.
Choose PET FILM for large flat scratch-resistant panels, as PET decorative film delivers stable dimensions and strong wear resistance. Pick PETG FILM for solid-color cabinet doors and shaped edge banding, since PETG decorative film eliminates bending defects in mass production.
SAINO’s technical team notes PET FILM and PETG FILM complement instead of replacing each other. PET decorative film leads the high-hardness flat segment, and PETG decorative film dominates flexible solid-color and edge banding markets. Factories should stock both PET FILM and PETG FILM to fulfill all flat and shaped door orders and unlock full value of PET decorative film and PETG decorative film.
