Common Questions

Frequently Asked Questions

Are these liners truly compostable at home?

Our liners are certified for commercial/industrial composting facilities. While they break down much faster than plastic, home composting may not reach the necessary temperatures for full degradation. We recommend checking with your local municipal compost program.

How do they compare to standard plastic liners?

Cup Source compostable liners offer comparable strength and leak resistance for typical commercial waste streams. They are ideal for general waste, dry recyclables, and food waste. For heavy construction debris or sharp objects, standard liners may still be preferred.

What is the minimum order quantity for custom printed liners?

Custom print orders typically have a MOQ of 1,000 cases. This allows us to optimize production runs and keep wholesale pricing competitive. Contact our sales team for a detailed quote based on your volume and design needs.

Do you provide certification documentation?

Yes. We provide BPI certification cards, MSDS sheets, and compostability guarantees with every order. These documents are available for download in your client portal upon request.
