Coatings for paper cups
Michelman technology. Coaterex support.
Develop cups with liquid resistance and heat sealing. We help you evaluate an alternative to PE linings, from coated paper to the formed cup.
A starting point with Michelman
Michelman presents Michem® Coat 9100 and 9250 for hot beverage cups. Selecting a grade for your project requires a technical review.
What we validate in your cup
This information helps prepare a useful trial and agree acceptance criteria.
Beverage and use
Drink type, ingredients, temperature and contact time. For cold use, include condensation and storage.
Paper and coating
Paper supplier and basis weight, coated sides, dry coat weight, coverage and available drying.
Forming and closure
Equipment, speed, sealing system, side seam and bottom. Measure seal strength and leakage after forming.
Sustainability supported by final-cup evidence
A water-based composition alone does not demonstrate recyclability, absence of plastic or compostability. Verify claims for the grade, structure and destination market.
Repulpability and recycling
Request the report applicable to your construction. Test results and acceptance by the local collection and recycling system are separate considerations.
Food contact
Review grade documentation for the food, temperature, time and country. Liquid resistance does not replace this evaluation.
Cost and process
Compare paper, coating consumption, drying, speed and waste. Confirm the required adjustments in a production trial.
Frequently asked questions
Does it work for hot and cold drinks?
Hot use is a starting point documented by Michelman. For cold drinks or both uses, we also assess condensation and exposure time before selecting a grade.
Can I keep my forming equipment?
We review your equipment and sealing window. The trial must confirm compatibility, speed, and temperature, pressure and time adjustments.
Will the cup be recyclable everywhere?
This cannot be guaranteed without knowing the construction and destination. Final-cup testing and acceptance by the relevant recycling system are needed.
What should I send to get started?
Drink type, paper, cup size, coating process and forming equipment, if known. The form lets you indicate which details are still pending.
