FAQ
What is PB1?
PB1 is Cove’s scalable molded fiber bottle platform, designed for recycling in paper streams.
What is PB1 made from?
PB1 packages are 90 to 95 percent fiber. The fiber blend typically includes wood and bagasse fibers with sizing additives and is compatible with a wide range of fiber types and sources. The inner barrier is a thin film laminate or coating, paired with a minimal injection-molded neck insert for sealing against closures, whether top seal or plug seal, as well as top-seals. Additional coatings and additives can be integrated to improve performance in wet environments such as showers while maintaining the repulpability of the bottles.
Is PB1 recyclable?
PB1 packages meet CEPI Class A and B recyclability standards and have shown high sorting success in real recycling facilities in Europe. US testing is underway, with initial repulping results completed successfully.
What barrier options are available?
PB1 supports multiple barrier films and coatings, including bio-based options. The barrier is selected by brands based on shelf-life requirements and the intended application. The platform is designed to operate with different barrier types, or with no barrier at all for products that do not require one.
Can PB1 use standard closures?
Yes. PB1 accommodates standard thread profiles and custom necks. The system is designed so brands can use their existing caps or move to new formats, such as fiber closures as well.
What product categories is PB1 suited for?
Personal care, beverages, homecare, beauty, nutraceuticals, concentrates, and other applications that benefit from a rigid, recyclable fiber format.
Do you have stock containers?
Cove currently offers PB1 as a custom solution, with each container designed for the specific needs of the customer. A range of standard PB1 stock formats is planned for future release.
What volumes and shapes are possible?
PB1 supports a wide range of sizes from 50 ml up to 2 L for liquids, with larger formats available for dry goods. The molded-fiber process accommodates almost any custom geometry, enabling distinctive forms and premium silhouettes without significant limitations on shape or design.
Can PB1 be custom branded?
Yes. Options include embossing, debossing, fiber coloring, direct printing, labeling, and custom surface textures. All decoration is designed to meet fiber recyclability.
Does PB1 support refills?
Yes. PB1 includes a refill architecture built around molded-fiber pods and premium cases.
How durable is PB1?
PB1 is designed to meet typical packaging performance requirements such as drop, top-load, and transport testing. Performance is tuned through fiber thickness and density, and barrier selection.
Can PB1 hold liquids long-term?
Yes. Shelf-life depends on barrier selection. PB1 can reach WVTR and OTR levels that support 36 months of stability for most liquids, creams, and concentrates.
Can PB1 be used in bathrooms or wet environments?
Yes. The fiber parts combined with coatings can facilitate moisture-resistance for shower use and wet environments. The barrier system protects the product contents independently of the outer fiber shell.
How does PB1 compare to plastic in carbon impact?
PB1 reduces lifecycle emissions by 30–70 percent depending on size, barrier choice, and distribution model. It uses renewable feedstocks and existing paper recycling infrastructure. A full lifecycle assessment is available upon request.
Is PB1 compostable or biodegradable?
The fiber components are compostable. Full bottle compostability depends on the selected barrier film. PB1 is designed first for paper recycling because it creates higher material recovery and lower emissions.
Can PB1 run on existing filling lines?
Most filling lines can run PB1 with minimal adjustment. The neck and opening can be designed to work with existing fillers and co-packers, lowering changeover requirements.
What does the development process look like for custom containers?
Cove scopes requirements, aligns on shape and volume, produces prototypes, validates barrier performance, then builds prototype tooling.
