Each 144 Sq in (929 cm²) Saves Natural Resources, Reduces Pollution 100% Recycled Paper Hypo-Allergenic Whitened Without Chlorine Bleach No DyesSeventh Generation napkins are made from 100% recycled paper, with a minimum of 80% post-consumer materials. Our napkins are whitened with an environmentally safe process - never with chlorine bleach. Your choice of our napkins makes an important difference today, and for the next seven generations. Here"s how: recycling paper prevents unnecessary landfilling of valuable resources. In addition to saving trees, producing recycled paper uses less water and energy than paper made from trees. Post-consumer materials are those that we recycle from our homes and offices that would otherwise be placed into landfills. By using post-consumer material we help "close the loop" to encourage more recycling and less waste of valuable resources.Our napkins are whitened without chlorine. This environmentally safe process keeps chlorine"s danger out of your home and our environment. Bleaching paper with chlorine creates dangerous toxins such as dioxin, furans, and other organochlorines. Once loose in the environment, these chemicals accumulate in both people and animals. Hundreds of studies have shown a direct link between dioxin exposure and cancer, birth defects and developmental and reproductive disorders.
