Biodegradable Clamshells made from Wheat Straw:
- Overview / Material: Made from wheat straw, a highly sustainable fiber that is a by product of the wheat harvesting process.
- Applications: Great for a range of hot & cold foods.
- Sizes: Range in size from 6″x6″x3″ (or 15oz) to 9″x9.6″x3″ (or 34oz). Available in single, double, and three compartment.
- Design: Typically available unbleached, though bleached options are occasionally available. The containers are soak proof and do not have any plastic or wax lining, however hot foods – and in particular hot, heavy foods – will cause the containers to “perspire” and some condensation can form at the bottom.
- Composting: Composting is required for biodegradation. These compostable clamshells are certified according to ASTM D6400 specifications. The clamshells will biodegrade within 30 days in a commercial composting facility, and within 90 days in a home composting system.
Clear Corn Clamshells (PLA):
- Overview / Material: Made from NatureWorks polylactic acid (PLA), which is derived from corn grown in the USA.
- Applications: Great for fruit, salads, cold sides, and warm dishes less than 110 degrees F.
- Sizes: Range in size from 6″x6″x3″ to 8″x8″x3″.
- Design: Meet the strictest scientific standards for biodegradability and compostability and are ASTM D6400-99 certified for “compostable plastics”. They are light and strong like plastic, but will fully biodegrade when composted.
- Storage: Should be stored in an environment that is less than 110 degrees F and not in direct sunlight or contact with heat.
- Composting: Composting is required for biodegradation. These biodegradable clamshells are certified compostable by the BPI and will biodegrade within 180 days in a commercial composting facility, but may take up to a year or more to biodegrade in a home composting system.

Do these products meet criteria for use in a microwave?
Hi Myra – All of our bagasse / wheatstraw products are freezer and microwave safe. The clear PLA (corn) plastic products are freezer safe, but not microwave safe (as they’re designed to break down at high heat levels).
Hope that helps!
