Hand wash, hand dry or towel dry.  Some foods may stain. Do not use in microwave.

• In the US, we use 30 billion plastic bags a year.  The production of which consumes 12 million barrels of oil.  Enough to power 750,000 cars a year.  The average consumer uses between 600 and 800 plastic bags per year.
• Plastic bags can take 1,000 years to degrade.
• Ocean water samples have shown more plastic particles than plankton.
• An average elementary school student eating homemade lunches is estimated to generate between 45 and 90 pounds of plastic baggies, foil pouches, and other packaging waste each year, roughly equivalent to the body weight of a third- to sixth-grader.

PVC is (polyvinyl chloride) plastic, commonly referred to as vinyl.  When produced or burned, PVC plastic releases dioxins, a group of the most potent synthetic chemicals ever tested, which can cause cancer and harm the immune and reproductive systems. PVC is the most common material used in insulated lunch bags. PVC is often used in conjunction with metals, including lead. The Center for Environmental Health (CEH) in Oakland, California filed a lawsuit on August 31, 2005 against several manufacturers and retailers of soft vinyl lunch boxes that were found to contain high levels of lead. The highest lead levels were found in the lining of lunch boxes, where it can easily come into contact with food, and where kids are likely to touch before handling their food.

Bisphenol A an organic compound used primarily to make plastics.  Suspected of being hazardous to humans since the 1930s, concerns about the use of bisphenol A in consumer products have been regularly reported in the news media since 2008 after several governments issued reports question its safety.
Since then multiple studies have found that disposable (and some reusable) plastics can leach BPA into the food and water when heated.  A new study from Harvard has found that urine levels of BPA are 69 percent higher after drinking cold liquids from polycarbonate plastic bottles.

According to the Breast Cancer Fund:  “BPA has been found in blood samples from developing fetuses as well as the surrounding amniotic fluid, and it has been measured in placental tissue and in umbilical cord blood at birth. CDC researchers also found BPA in 95 percent of about 400 urine samples from a broad national sample of adults.   Several studies using both rat and mouse models have demonstrated that even brief exposures to environmentally-relevant doses of BPA during gestation or around the time of birth lead to changes in mammary tissue structure predictive of later development of tumors. Exposure also increased sensitivity to estrogen at puberty. Recent data demonstrate that early exposure to BPA leads to abnormalities in mammary tissue development that are observable even during gestation.”
