1. What is 80% RPET Sheet?
80% RPET rigid sheet is a modified recycled PET material produced by co-extruding high-purity food-grade recycled PET flakes with a small proportion of virgin PET. The 80/20 formula is a mature and optimized industrial solution in the packaging industry.
Different from ordinary 100% recycled PET sheets, the 20% virgin PET addition effectively improves the transparency, toughness, thermoforming stability and anti-whitening performance of the sheet. It solves the common defects of pure recycled materials such as yellowish tint, low clarity and easy cracking.
2. Production Raw Material & Process
2.1 Raw Material Source
Qualified 80% RPET raw materials are mainly sourced from clean post-consumer PET bottles, including drinking water bottles and food-grade PET containers. After strict sorting, de-labeling, multi-stage cleaning, impurity removal and high-temperature drying, the materials reach food-grade production standards.
2.2 Production Technology
80% RPET sheet adopts professional physical recycling and co-extrusion technology. The whole process includes flake purification, viscosity enhancement, melt filtration, co-extrusion molding, calendering and cooling. Multiple fine filtration procedures ensure zero impurities, low odor and stable viscosity, meeting high-standard export packaging requirements.
3. Core Advantages of 80% RPET Formula
Higher Environmental Value: 80% PCR recycled content meets global ESG, carbon neutrality and sustainable packaging policies, supporting brand green upgrading.
Excellent Transparency: Effectively avoid yellowing and haze problems of 100% RPET, achieving high clarity close to virgin APET sheet.
Improved Toughness & No Folding Whitening: The virgin PET component optimizes ductility, reducing folding white marks and cracking during blister processing.
Stable Thermoforming Performance: Uniform shrinkage rate and strong stretching adaptability, suitable for deep drawing and high-speed automatic blister production.
Cost-Effective: More affordable than full virgin PET sheet, with far better performance stability than ordinary low-purity recycled PET materials.
4. Main Application Scenarios
With dual advantages of environmental protection and high appearance, 80% RPET sheet is widely used in mid-to-high-end transparent blister packaging:
Food Packaging: Fruit trays, bakery packaging, dessert boxes, food blister inner trays
Cosmetic & Beauty Packaging: Transparent cosmetic trays, gift box inner supports, skincare product packaging
Electronic & Hardware Packaging: Precision part blister trays, transparent clamshell packaging
Daily Consumer Goods: Toy packaging, retail display packaging and household product blister packs.
5. Why 80% RPET Is Better Than Other Materials
Compared with 100% Virgin APET: Lower cost, higher recycled content, better for brand environmental promotion, with negligible appearance difference.
Compared with 100% RPET: Higher transparency, no yellow tint, better toughness, no folding whitening, more stable thermoforming and higher finished yield.
Compared with 50% RPET: Higher environmental value, more in line with international high-standard recycled packaging requirements.
