What Makes PET Rainbow Film Stand Out?
Exclusive Rainbow Optical Effect & Precision Craftsmanship
Crafted via advanced biaxial stretching+optical diffraction technology,JUNCHI’s PET rainbow film features dynamic rainbow color shifting-displaying vibrant red,orange,yellow,green,blue,indigo,and violet hues when exposed to light.The optical effect is achieved through micro-nano surface structures (≥3000dpi resolution),ensuring uniform color distribution and consistent diffraction across the entire film width.Made of high-purity PET resin,the film boasts exceptional transparency (light transmittance ≥93%) and low haze (≤1.0%), allowing the rainbow effect to shine brightly without distortion.
Core Advantages: Standardization & Performance
Strictly Standardized Sizes:Fixed 16μm/22μm thickness and 6200m/roll length ensure compatibility with standard packaging/printing equipment,reducing production adjustment time and material waste.Multiple width options (635mm-1400mm) fit diverse application needs-from small-label production to large-format packaging.
Superior Physical Properties:Tensile strength ≥210MPa(16μm)/≥230MPa (22μm),excellent dimensional stability (heat shrinkage ≤1.5% at 120℃/30min),and resistance to moisture, oil,and UV radiation.The film’s surface is treated for enhanced printability and lamination compatibility,supporting UV, offset,and flexo printing.
Eco-Friendly & Durable:Recyclable PET base material (ROHS certified),non-toxic and odorless-meets global environmental standards for packaging materials.Scratch-resistant surface (H-level pencil hardness) ensures the rainbow effect remains vivid even after processing and transportation.
Optimized Layer Structure
PET Core Layer→Micro-Nano Optical Diffraction Layer→Anti-Scratch Coating→Anti-Static Coating
The dual protective coatings enhance durability and processing adaptability,while the micro-nano diffraction layer amplifies the rainbow effect-ensuring bright,eye-catching color shifting from all viewing angles (120° wide viewing range).
Targeted Applications
Leveraging its vivid rainbow effect and standardized sizes,the film is ideal for:
Packaging Industry:Cosmetic boxes,gift boxes,food packaging (snacks, candies),beverage labels,luxury product outer packaging (adds visual appeal to stand out on shelves).
Printing & Decoration:Branded stickers,promotional posters,gift wrapping paper,party decorations,and in-mold decoration (IMD) for consumer electronics.
Craft & Hobby:Scrapbooking,DIY projects,festival decorations,and decorative laminates for paper/card stock.
Specialty Uses:Stage backdrops,display materials,and premium book jackets (1270mm/1400mm wide options for large-format applications).

FAQ Highlights (Full Guide Available Upon Request)
What’s the difference between 16μm and 22μm thickness?
16μm:Lighter,more flexible-ideal for labels, wrapping,and thin packaging.
22μm:Thicker,more durable-suitable for heavy-duty packaging,decorative laminates,and applications requiring higher structural stability.
Can it be laminated with paper or other materials?
Yes.excellent bonding strength with paper,card stock,and plastic substrates;supports hot-melt and cold lamination processes.
Is the rainbow effect fade-resistant?
Yes,UV-resistant coating prevents color fading,ensuring the rainbow effect remains vivid for 1+ year under normal storage conditions.
