The PB1 Platform
Built to Scale. Engineered for Impact.
Single-piece fiber bottles have failed to scale because of long cycle times, rough surface finish, and high unit costs. PB1’s multi-piece architecture solves these limitations by enabling fast production, premium surface finish, and compatibility with existing molded-fiber lines. PB1 is a scalable, high-performance solution that allows brands to meet new global packaging regulations, consumer demands and retailer mandates for a truly future-proof solution.
Designed for Paper Recycling
PB1 meets CEPI Class A and B paper-recyclability standards and has demonstrated 84%+ sorting success in independent, real-world recycling tests in Europe. PB1 is designed to be processed within standard paper-recycling systems without requiring consumer disassembly. Consumers can place PB1 bottles in household paper-recycling streams, which remain the most widely recovered packaging material globally.
High-Performance Bio-Based Barrier Solutions
PB1 supports a range of high-performance barrier films designed for circularity. The system is compatible with most film-based laminates, with Cove’s focus on bio-based barriers that match the moisture- and oxygen-protection levels of leading packaging formats. Independent testing shows PB1 achieving WVTR below 1.0 g/m²/day and OTR below 1.0 cc/m²/day, supporting long shelf-life requirements for liquids, creams, and concentrates. Barrier performance is achieved while meeting CEPI paper-recyclability standards.
Lower Carbon by Design
Independent life-cycle assessments show PB1 can achieve significant carbon-emission reductions compared to conventional plastic and composite packaging, with modelled scenarios indicating 30–70% lower CO₂e depending on format and use case. These reductions are driven by renewable feedstocks, efficient fiber-molding processes, and compatibility with existing paper-recycling systems, which together reduce material and energy demand across the value chain.
Certified and Proven
PB1 and our manufacturing partners operate to internationally recognized quality and environmental standards, and the system has undergone extensive independent testing.
Adaptable Design. Easy Integration
Create virtually any container shape (50ML-1L+), with options for direct printing, embossing, debossing, coloring, and labeling. Compatible with standard filling lines, PB1 can integrate seamlessly into existing supply chains without costly modifications.
