BASF & DoBauCheng BoCarbon PHA Emulsion Series: Application Sharing

Our Project – Introduction 

About Jinyinlian 

Jinyinlian has been established for 28 years and is a holding company of Global Printing, Shaanxi Pharmaceutical Group (Stock Code: 002799). It has five subsidiaries located in Tianjin, Dongguan and Guangzhou. 

Provides professional technical services and material supply to 500+ printing and packaging companies 

National High‑tech Enterprise 

National Specialized and Sophisticated “Little Giant” Enterprise 

Project Introduction 

In 2024, the construction of the environmentally friendly packaging paper project for food and pharmaceuticals was completed. Currently, we own a 1,700 m² Class 100,000 food packaging clean workshop, 3 coating machines, and fully use the BASF & DoBauCheng BoCarbon PHA emulsion series. This allows full coverage of paper grades from 30 g to 450 g, suitable for various coating packaging applications. 

Our features: off‑line coating, flexible and fast delivery, suitable for both small and large batches, especially for rapid R&D breakthroughs in personalized niche markets. 

Deep cooperation with BASF & DoBauCheng and the promotion and application of BASF & DoBauCheng BoCarbon PHA emulsion series is Jinyinlian’s strategic goal. 

PHA Bio‑based Coated Paper Project – Project Report 

Application Report – Comparison of technical data for BASF & DoBauCheng BoCarbon PHA emulsion series products  

Conclusion: Fast drying speed, saving equipment power consumption; the paper cup machine runs stably and quickly, and the forming effect is better than that of other emulsion coating products, basically reaching the effect of PE extrusion coating. 

Technical Extension 

Based on the PHA emulsion products, we will continue to research and develop combinations of different coating methods such as anilox roller, air knife, and doctor blade, as well as upgrade coating equipment, to further increase coating speed and the performance of coated paper products. 

Quality Inspection – Laboratory 

Jinyinlian has physical and chemical laboratories, equipped with professional instruments such as gas chromatographs, GC‑MS, liquid chromatographs, atomic absorption spectrometers, etc., to test the applicability and safety of coated paper products. It is also equipped with paper cup machines, carton machines and other equipment to test the forming performance of coated products, providing technical application services for the end market. 

Quality Inspection – BASF & DoBauCheng BoCarbon PHA emulsion series products 

Our test conclusion: It can achieve process indicators such as oil resistance Kit 12, water resistance Cobb 30min < 10 g/m², moisture resistance MVTR < 30. Heavy metals, bisphenol A and other indicators all meet food‑grade standards. 

PHA Bio‑based Coated Paper Project – Project Advantages 

Project Advantages – Comparison of end‑user validation data for BASF & DoBauCheng BoCarbon PHA emulsion series products  

Conclusion: PHA coated paper has lower odor; higher folding endurance; better oil resistance; superior printability on the coated surface; compared to EAA coatings (which tend to stick at high temperatures) and ordinary acrylic coatings (which tend to stick when wet), PHA coatings offer better transport safety. 

Technical Extension

The strong R&D capabilities of BASF and DoBauCheng provide us with multiple product solutions for different applications. Thanks to BASF and DoBauCheng for their strong support! 

PHA Bio‑based Coated Paper Project – Project Applications 

Project Applications – BASF & DoBauCheng BoCarbon PHA emulsion series products 

For BASF & DoBauCheng BoCarbon PHA emulsion products, Jinyinlian has completed trials and partial practical applications in many fields such as paper tableware, food packaging, cold drink packaging, heat‑seal bags, waterproof shipping boxes, oil‑proof paper, pharmaceuticals, paper bags, etc. The performance of the coated paper products fully meets the requirements for practical applications. 

Future Outlook 

In 2026, Jinyinlian plans to actively promote PHA environmentally friendly coated paper products to large domestic and international brand owners, and work with partners to carry out R&D and promotion for various application scenarios. 

PHA Bio‑based Coated Paper Project – Production Capacity 

Current Capacity 

The current annual capacity of the Tianjin plant alone is about 20,000 tonnes. 

By 2027, the annual capacity will reach 40,000 tonnes.

Future Capacity Layout

With strong support from the group, the PHA bio‑based coated paper project will be planned in stages according to market demand. 

Add a coating plant in Tianjin Beichen 

Add a coating plant in Xi’an 

Add a coating plant in East China 

Add a coating plant in South China 

Goal: Work together with BASF and DoBauCheng to reach an annual capacity of 200,000 tonnes, gradually achieving national coverage.
