Every paper cup and bowl connects foodservice with papermaking, coating and forming, and with what happens to the fibers after use. Improving paper-based foodservice packaging means considering barrier performance, production efficiency, the dining experience and end-of-life treatment together.
BIOTEN designs packaging around three priorities: using less material at the outset, recovering resources after use and allowing for biodegradation where appropriate. It selects materials, coating structures and converting processes to suit the intended use. BIOTEN Plus 4108 is a bio-based, waterborne composite barrier emulsion that can be applied by coating or spraying to paper cups, bowls and other paper-based foodservice packaging.
Water and grease resistance are basic requirements. For 4108, typical Cobb water absorption is 2–8 g/m² and the grease-resistance Kit rating is 7–12. Reference coating line speeds range from 80–1200 m/min, and reference cup-forming speeds range from 90–280 cups/min. Efficient coating and high-speed cup forming depend on matching the emulsion to the base paper, coat weight, drying conditions and heat-sealing settings.
A natural paper feel and a clean sensory profile. The formulation emphasizes low odor and preserves the feel of paper. It contains no intentionally added PFAS, plasticizers or wax emulsions. Substances of concern are strictly controlled, and the source of the bio-based carbon is traceable.
Assess resistance to heat and humidity and suitability for food contact for the intended temperature, contact time and packaging structure. Repulping for fiber recovery and biodegradation under composting conditions must also be assessed for the finished article and the treatment process available.
BIOTEN Plus is the balanced range, Pro serves specialist applications, and Ultra is designed for custom development.
BIOTEN invites base-paper suppliers, coaters, converters and foodservice brands to bring their application requirements to joint sample testing, process trials and product development. Technical data sheets (TDS) and safety data sheets (SDS) are available on request.
