Boiled water is the most stringent "blind test" for paper cups. It does not have the aroma of coffee, tea, or milk to cover you up; any subtle smell of paper, glue, or miscellaneous smells will be amplified. Hot water will further accelerate the "development": the higher the temperature, the stronger the infiltration, the faster the volatilization and migration, and the higher the sensitivity of the entrance to the smell and taste.
This is why the "original taste" of a hot drink should not be interrupted by the smell of paper, coating, softness and discomfort in holding it. The upgrade of paper cups cannot stop at the "easy to recycle/compostable" label - food contact safety and compliance should be the bottom line, experience indicators and engineering indicators should be achieved simultaneously, and consistency of large-scale delivery should be achieved.
In January 2026, DBC teamed up with BASF to carry out evaluation and application verification for leading customers in the paper-based food packaging segment, and provided Bioten™ Plus (BIOTEN Balance Type) "Bioten™ Plus | Bioten Bio-based PHA Water-based Barrier System". This system is based on the Bioten™ biological high-performance emulsification innovation system, collaboratively introduces PHA bio-based materials in microstructure factories, and combines it with BASF's aqueous dispersion purification and filtration process platform. Through refined process control during the emulsion preparation and scale-up process, "low odor, batch consistency, stable machine operation and stable molding" are solidified into engineering capabilities - under the conditions of the agreed base material, coating amount and process window, the "original taste" no longer relies on chance and batch fluctuations, but is guaranteed by systematic manufacturing and quality control.
BIOTEN Black Technology: We use 4 results that can be directly verified by users to define
1. Stable water resistance: no leakage under high-temperature liquid conditions; no leakage or collapse for 72 hours under typical working conditions; 2. Stable structure: adaptable to molding and heat sealing processes; in paper cup molding with a tempo of 150 cups/minute and a hot air system setting Under constant 360°C conditions, the sealing strength and consistency remain stable; 3. Pure entrance: boiling water has no odor and restores the original flavor of the drink; 4. Microwave heating: no leakage, no deformation, no yellowing, no odor, and the grip remains firm.
For China's paper-based packaging industry chain, the value of upgrading lies in "running well, running steadily, and running consistently" - turning high standards into scalable product value, turning consistency into brand assets, and forming a Chinese manufacturing standard and delivery paradigm that leads the world. We establish verifiable process windows around coating, drying/curing, heat sealing and molding, and use digital delivery packages to support customers in achieving consistent output under established substrate and production line conditions: process window locking, curve and dosage management, heat sealing window verification, pilot scale-up, third-party testing and verification, ECN change control and traceability.
High water resistance and strong stiffness are the performance; purer entrance and more stable quality are the experience; carbon reduction at the source, terminal recycling and degradation are optional, which is the professional path for sustainable development.
Boiled water can pass the test, so drinks are more reliable.
If you want to evaluate the water-based barrier upgrade route of Bioten™ Plus (carbon balance type) in paper-based packaging such as paper cups, soup bowls, lunch boxes, tissue paper, kraft paper, etc., please leave a message/private message and provide application scenario information: substrate type/gram weight | coating method | target barrier | molding speed. After passing the review, we will provide samples and verification path suggestions to turn the "original taste" into a deliverable, reproducible, and scalable consistent product experience, and help you serve more high-end catering chain brands in 2026.
