Global Launch of High-Barrier, Cost-Effective Alternative to Imported Solutions
Jan 23,2026
January 23, 2026 – A joint R&D effort by Sichuan University Qingdao Research Institute and Tsingtao Beer has yielded a revolutionary TPE (Thermoplastic Elastomer) cap liner compound, disrupting the high-end packaging material market dominated by foreign suppliers. This game-changing material has officially entered mass production, with over 50 million units tested and validated in commercial applications.
The new TPE compound outperforms imported counterparts in critical performance metrics: tensile strength, elastic modulus, and elongation at break exceed international standards, while offering equivalent hardness and air permeability. Key advantages include:
- Zero flavor interference: Transparent and odorless, ensuring product integrity for beer, beverages, and food items
- Superior sealing efficiency: Oxygen transmission rate (OTR) of 405 cm³/m²·24h·0.1MPa, outperforming imported liners by 11%
- Enhanced processability: Melt flow index of 16 g/10min and shear viscosity of 914Pa·s (200/s), enabling precise molding with ±3% dimensional tolerance
- Cost competitiveness: 20-30% lower price point than imported materials without compromising quality
Certified by SGS for food contact safety, the liner meets global regulatory standards including FDA and EU 10/2011. It is particularly suited for carbonated drinks, preventing CO₂ leakage with a load decay rate of 32.48% (vs. 36.75% for conventional liners) during long-distance transportation. "This innovation addresses the industry's pain point of relying on expensive imported materials," said a project lead. "We aim to supply 200 million units annually to global beverage brands by 2027."
