PHA Cup Lids — Compostable Lids for Hot and Cold Cups
Injection molded lids made from 100% PHA that complete a fully compostable cup system. Conventional plastic and PLA lids are the component most often left behind when brands switch to paper cups, because paper cups themselves are rarely compostable and PLA lids soften in hot service. PHA lids resist heat to 85°C, snap securely onto paper and PHA cups, and are home compostable and marine biodegradable with no PFAS treatment. Available as flat lids for cold drinks and dome lids for beverages with foam, cream, or toppings.

Frequently Asked Questions About PHA Cup Lids
What is PHA Cup Lids made of?
PHA Cup Lids is made from 100% PHA (Polyhydroxyalkanoates), a bio-based polyester produced by bacterial fermentation of renewable feedstock. Unlike petroleum-based plastics, PHA is derived from non-food plant sugars using Chinese indigenous bacterial strains. The material is certified by BPI, TUV Austria (OK Compost HOME, OK Compost MARINE), and DIN CERTCO for complete biodegradation in ocean, soil, home compost, and industrial compost environments.
How long does PHA Cup Lids take to biodegrade?
PHA Cup Lids biodegrades completely within 6-18 months in home compost. In industrial composting facilities (58°C+), degradation occurs in 3-6 months. In marine environments, complete biodegradation takes 1-3 years. The process produces only CO2, water, and biomass — no microplastics or toxic residues remain.
What certifications does PHA Cup Lids hold?
PHA Cup Lids holds TÜV OK Compost HOME, BPI, OK biodegradable MARINE, FDA 21 CFR, EU 10/2011. These certifications verify that the product meets international standards for biodegradability, compostability, and food contact safety. PHApack products are tested per EN 13432, ASTM D6400, ISO 14855, and ASTM D6691 standards by independent laboratories.
What is the minimum order quantity and lead time?
The standard MOQ for PHA Cup Lids is 500 kg. Lead time is typically 15-25 days after order confirmation. For custom OEM orders with specific dimensions, colors, or branded printing, lead time may extend to 25-35 days. Trial orders from 100kg are available for evaluation.
