Telescopic paper straws
Compact for packaging. Extended for drinking.
A compact two-piece format designed around the cup, the pack and the way the drink is opened.
- Compact when packed
- Extended when needed
- Developed around your cup

CITY
Building a circular, sustainable city from paper.
From telescopic paper straws and water-resistant coated paper to paper tableware and molded-fiber coatings, LVTU develops practical paper-based solutions for a more circular food-and-beverage world.

01
Telescopic paper straw
In a comparable format, the collapsed straw can be nearly half the packed length of a conventional straw—reducing pack volume and transport cost.
Evaluate the packLVTU CITY systems
Four systems. One paper-based city.
Water-resistant coated paper straws
Designed to stay functional where ordinary paper softens.
A coated paper-straw system developed around defined drink conditions and the intended serving time.
- Reduced lip sticking
- Less foaming in carbonated drinks
- Reduced coffee staining
- Slower softening in liquids
Performance paper plates
Developed with European-market requirements in mind.
Produced with a closely integrated manufacturing partner, while LVTU coordinates specification, documentation, sampling and supply.
- Food-contact project review
- Structural stability
- Managed partner supply
Molded-fiber coating
Functional coatings for demanding hot-food applications.
A water-based coating solution developed to help address microwave use, perceived odor and food release in molded-fiber containers.
- Microwave-use evaluation
- Lower perceived odor
- Improved food release
Engineering layer
Make paper
work harder.
A better paper city depends on materials and structures that perform. The telescopic straw shows how we connect compact packaging, controlled extension and the final drinking experience.- Tube diameters

The inner tube’s 10 mm tail expands to 12 mm OD. It travels inside the 12 mm bore, then stops behind the outer tube’s 10 mm-long, 11 mm neck so the inner tube cannot pull free.
Performance is a test, not a slogan.
Every strong claim needs a defined substrate, food type, temperature, contact time and test method. Our content and sampling process make those conditions visible.

Food-simulant extractives
Evaluate coated paper under defined acidic, alcoholic and fatty-food simulation conditions. LVTU coating development targets lower extractives, with conclusions tied to the exact substrate, coat weight and laboratory report.
3% acetic acid · ethanol · isooctane · defined time / temperatureTesting context: EN 1186-3:2022 and GB 4806.10-2025, with particular focus on extractables testing using acetic acid, ethanol and isooctane. The applicable simulant concentration, contact time and temperature are confirmed against the intended use and the project test report.
