Our Earth's Natural Alternative 6" heavy-duty cake/dessert plate is made from 100 percent sustainable and renewable wheat stalk fiber and bagasse (sugarcane fiber). The material is derived from the plant stalk, not the actual food grains. They are gluten-free. They are an environmentally beneficial tree-free alternative to plastic or Styrofoam, which contain non-biodegradable and petroleum derived materials or paper, which manufacturing requires the cutting down of trees. They are compostable in either a industrial compost (1-6 months) or a home compost (up to 12 months). Built sturdy from 100 percent environmentally beneficial natural, renewable plant fibers, they can be used in the microwave - as they are heat safe up to 200 degrees Fahrenheit - and are oil/liquid and cut resistant. Their tan, natural, dye free, bleach free coloring is the perfect for any occasion -holiday parties, gets togethers, bridal showers, weddings or everyday use. Contains 20 in each case.
