Enhance your kitchen storage with our environmentally-friendly and long-lasting Premium Silicone and Astrik Mixing Bowl Lids. Specifically made to fit snugly on our five mixing bowls, these lids form an airtight seal to preserve the freshness and security of your food. Crafted from sustainable and innovative materials, they offer an ideal combination of functionality and eco-friendly design. Astrik is a revolutionary composite material created from PLA (Polylactic Acid) and plant fiber, such as bamboo. PLA, a biodegradable thermoplastic derived from renewable resources like corn starch or sugarcane, is combined with discarded bamboo ends from furniture manufacturing. This unique material is safe for use in the dishwasher and microwave, providing a sustainable alternative to traditional plastic options.
