Thank you for asking about using Ziploc® bags to make omelets. While we
appreciate hearing about new and innovative ways to use our products, we must be
cautious that these new ideas follow label directions.
Ziploc® bags are not designed or approved to withstand the extreme heat of
boiling and therefore, using Ziploc® bags to make any recipe that requires the
bag to be boiled is not recommended.
Like all of SC Johnson's products, Ziploc® bags can be used with confidence when
label directions are followed. All Ziploc® Containers and microwaveable Ziploc®
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.
Please share these facts with others who may have this misleading information.
We also encourage people to go to www.ziploc.com
for more information on the
proper use of this product.
Thank you for giving us a chance to set the record straight.
