I recently heard media reports that plastic products contain a chemical that can encourage prostate cancer. Do SC Johnson's plastic products contain BPA (bisphenol A)?
A recent study conducted and published by the University of Cincinnati found that the estrogen-like chemical BPA (bisphenol A) has been shown to encourage the growth of a specific category of prostate cancer cells. BPA is commonly used in the manufacture of certain plastic products, such as food-can coatings, milk-container liners, food containers, and water-supply pipes. As a result, media have been reporting on this study and the fact that this chemical is commonly found in plastic food storage containers.
SC Johnson does not use BPA in its plastic products, Ziploc
brand Bags and Containers.
SC Johnson is a leader in providing high-quality products. All of its products are extensively evaluated for toxicity and safety and comply with—and often even exceed—applicable quality and safety regulations.

I have read an email that warned consumers about the alleged dangers of using Ziploc
brand products in the microwave. Is this information true?
In 2002, we became aware of an email that was being widely circulated, which warned consumers about the alleged dangers of using plastics in the microwave. This email claimed that the combination of fat, high heat, and plastics releases dioxin into the food and ultimately into the cells of the body, thereby increasing the risk of producing cancerous cells. We researched these claims and it is clear that the information is misleading, and unnecessarily alarms consumers.
brand products are 100% dioxin free. You also should be aware that dioxins can be formed only when chlorine is combined with extremely high temperatures, such as 1,500°F, which even the most powerful consumer microwave ovens are unable to produce.
brand products can be used with confidence when label directions are followed. All Ziploc
brand Containers and microwaveable Ziploc
brand Bags meet the safety requirements of the U.S. Food and Drug Administration (FDA) for temperatures associated with defrosting and reheating food in microwave ovens, as well as room, refrigerator, and freezer temperatures.
Like all Ziploc
brand products, Zip’n Steam
Bags are dioxin free. Additionally, they are specially designed for microwave use and meet the safety requirements of the U.S. Food and Drug Administration (FDA) for temperatures associated with cooking food in the microwave when label directions are followed.
Please help us alleviate consumers' concerns and share these facts with those who forwarded this misleading e-mail to you, and to whom you may have sent it. Thank you for giving us a chance to set the record straight.
Can I use Ziploc® Zip’n Steam® Bags to cook on the stove?
No. Ziploc® Zip’n Steam® Bags are designed ONLY for use in the microwave. Do not use in a conventional oven, under browning elements, or on the stovetop. Ziploc® Zip’n Steam® Bags are not designed for boiling.
How do I get Ziploc® brand Big Bags to stand up?
To stand up Ziploc® brand Big Bags, place both hands inside the bag and open the pleat. Slide fingers toward the corners of the bag, making a flat, rectangular bottom.
How are the Ziploc® brand Flexible Totes different than Ziploc® brand Big Bags?
In addition to the benefits Big Bags offer, Flexible Totes are made of thicker, pliable plastic with the additional benefit of stackability. Its thicker film, zipper and overall construction lends to improved durability and long-lasting storage capability.
