What are Spillahs® made from?
Spillahs® are made from food grade High Density Polyethylene (HDPE). HDPE is identified on plastic containers by the #2 code. Plastics coded #4 and #5 are also safe for food and drink use but are not as recyclable as HDPE. HDPE is the best plastic for use with drinks because it is not biodegradeable. HDPE does not break down in sunlight or when it comes in to contact with liquid. Therefore, it will not biodegrade and leech carcinogens or endocrine disruptors. source: nontoxiclife.com.au HDPE will return to its original shape after it has been bent.
