  • Marine-degradable PHA option. For sea-going operations and coastal cafés that want a closer-to-zero-impact straw.

OEM, private label, and bulk orders

Standard sizes ship from inventory; OEM, ODM, and private-label runs with custom dimensions and branded artwork ship factory direct from our Shenzhen facility. Print methods include flexo (volume-cost efficient at 10,000+ units), digital (short-run / multi-SKU / seasonal artwork), and embossing (premium-positioned items). All inks are food-safe and either water-based or UV-cured — both compost end-to-end.

Frequently asked questions

Will paper straws go soggy?

Our paper straws hold for ~30+ minutes in hot drinks, ~60+ minutes in cold. For longer service, PLA or PHA straws stay rigid throughout.

Are PLA straws marine-degradable?

No — PLA needs industrial composting. For marine degradation, choose PHA straws.
