February 2026, the beginning of the new year. DBC ushered in a major milestone: its innovative product, Bioten™ PHA bio-based water-based barrier coating, successfully passed various rigorous audits and officially obtained the three most authoritative international compost certifications of ABA, BPI and DIN CERTCO and obtained certificates.
This key progress marks that DBC Bioten™ PHA water-based barrier coating has overcome technical barriers and completed the rigorous verification of the "industrial composting + household composting" dual system while maintaining the industry-leading "easy recycling and high repulping rate" technical route.
We have successfully achieved a key breakthrough in the paper-based barrier system for tableware and food packaging, and officially delivered a system-level solution of "high performance + recyclable repulping + compostable disposal" to the global market.
■ BIOTEN gathers endorsements from international institutions to open up a global compliance path
The simultaneous acquisition of the three major compost certifications and the sapling logo means that the "compliance language" of Bioten™ PHA bio-based water-based barrier coating in the high-quality and cost-effective regional market has been highly unified. This will significantly reduce the cost of cross-border compliance communication for overseas product processing companies, break down technical barriers in Europe and the United States, improve product introduction efficiency, and pave a clear, high-quality and cost-effective connection path for catering brands and product processing companies.
■ Adhere to the safety red line and obtain the new national standard for food contact coatings, "First Inspection Excellent"
While pursuing the ultimate in environmental protection and degradability, the absolute safety of food contact materials has always been the red line that we attach most importance to and must never touch. Together with our strategic partner BASF, we have gone through more than three years of continuous optimization and iteration. On the basis of fully complying with the FDA and China's most stringent food contact material safety standards, BIOTEN PHA bio-based water-based barrier coating achieves the ultimate purity, safety and environmental protection experience of "tasting as clean as water".
On the domestic compliance side, Bioten™ PHA bio-based water-based barrier coating has another good news - it has successfully obtained the first full compliance test report in 2026 for the latest version of the mandatory standard "GB 4806.10-2025 National Food Safety Standard - Coatings and Coatings for Food Contact Materials and Products" jointly issued by the National Health Commission and the State Administration for Market Regulation. On January 4, 2026, the National Key Laboratory of Food Contact Material Testing (Changzhou) officially issued 4 product test reports, all of which were qualified.
Dual-track parallel hard-core safety verification at home and abroad is using absolute strength and national-level test data to build the strongest fortress of trust for the papermaking and coating industry chain, and also adds core new options for the high-end products of tableware and tableware companies.
■ Adhere to first principles: Only by restoring the problem to its real constraints can we go through the cycle
Over the years, DBC has always insisted that innovation starts from "first principles". Product innovation in paper-based food packaging must simultaneously meet the scientific and engineering practicality of sustainable development: put key constraints such as material performance, production line technology, food contact safety, recycling and repulping and terminal disposal in the same "real-world constraint list" to solve systematically, avoid falling into the path of "the global market is vast, but Chinese companies can only rely on low prices to gather overseas orders", and gradually get rid of the competitive quagmire of inefficient internal consumption and inferior quality cycles.
In recent years, the bio-based PHA water-based barrier coating system initiated by DBC and promoted by industry chain partners is committed to establishing a verifiable technical path of "carbon reduction at the source, recycling at the end, and optional degradation". Plastic reduction and carbon reduction will remain the global theme of disposable tableware. We should leverage the advantages of China's manufacturing supply chain to promote paper-based tableware towards high-end, branded and large-scale delivery, and form a reasonable premium based on quality and compliance in the international market.
To this end, DBC will maintain strategic "restraint" in the commercial expansion of BIOTEN PHA water-based coatings and carefully select partners: empower the industry chain with an auditable compliance evidence chain and a replicable engineering system, and jointly build a multi-dimensional, high-quality evaluation system and product specifications that benchmark international access and customer review requirements, so that China's intelligent manufacturing can win long-term trust and high-quality premiums in international competition.
Bioten™ bio-based PHA water-based system solutions solve real-world systemic challenges. We are using verifiable and sustainable technical strength to inject strong new productivity into the high-quality development of the industry.
■ BIOTEN matrix launches: BIOTEN core product line and market guidance price disclosed
In order to more accurately solve the core pain points of different packaging scenarios and reduce information friction in the industry chain during the selection, introduction and verification process, BIOTEN has launched three major scenario-based product lines and disclosed market guidance prices:
01 / Bioten™ Plus (BIOTEN Balance Type): Meets the general needs of paper-based disposable tableware, focusing on environmental protection, odorless, anti-leakage, high water/oil resistance and production line adaptability; the entire series is fluorine-free and safe, emphasizing easy recycling, repulping-friendly and taking into account the composting disposal path, suitable for large-scale introduction and cost-effective applications. Market guide price: 36,000-45,000 yuan/ton.
02 / Bioten™ Pro (customized type): For high-demand food packaging, focusing on programmatic customization of high barrier properties such as moisture-proof, oxygen-blocking, and odor-blocking; it can be combined with the target market's disposal path and verification system to optimize key performance and disintegration/degradation performance on the application side. Under specific testing methods and disposal conditions, a faster disintegration/degradation compliance window can be achieved (such as the target interval of 21-52 days for industrial compost); compared with the 180-day evaluation window commonly used in systems such as BPI/ASTM, the verification cycle can be significantly shortened to meet the introduction needs of high-demand areas or customer audit scenarios. Market guide price: 48,000-69,000 yuan/ton.
03 / Bioten™ Ultra (BIOTEN high-resistance type): Specially developed for paper-based barrier requirements such as difficult liquid packaging and paper bottles, focusing on key indicators such as oxygen barrier and leakage prevention; it can be verified and imported based on the paper-based structure, coating amount and application conditions. The current stage can support program verification of 7–30 days shelf life target under specific application conditions (longer shelf life versions are being continuously verified and iterated). Market guide price: 92 yuan/kg.
The new journey in 2026 has begun. We are willing to work hand in hand with upstream and downstream partners to jointly promote the large-scale and high-quality application of bio-based PHA water-based barrier coatings: with an auditable evidence chain and a replicable engineering system, we will improve import efficiency and product certainty, and form a stronger overall technological competitiveness of China on the international stage. The most important thing is that we will use leading technology and firm long-termism to continue to improve the product competitiveness and profitability of our partners.
