  • "Food Safe" or "Food Grade" Plastic?

    I recently read that food safe plastic containers will have the recycle triangle with the number 2 inside. Then, my wife and I went to a restaurant last weekend and brought home leftovers in a plastic container. The container looked like it was obviously designed for food, but it had the number 5 in the triangle. Is there any way to tell at a glance whether plastic is food safe or not?

    Properties: toughness, strength, resistance to heat, grease, oil, and chemicals, barrier to moisture. Density: 0.90-0.92 g/cc
    Statistic: In 1999 PP accounted for 2% of plastic bottle resin sales.

    Description: Polypropylene has the lowest density of the resins used in packaging. It is strong and is resistant to chemicals. Since it has a high melting-point it can be utilized in applications requiring that a container be filled with a hot liquid.

    Packaging applications: Yogurt containers, syrup bottles, ketchup bottles, caps, straws, medicine bottles (so yes, I'd say it's food grade)
    Recycled products: Signal lights, battery cables, brooms, brushes, auto battery cases, ice scrapers, landscape borders, bicycle racks, rakes, bins, pallets, and trays

      Good info. So are just numbers 2 and 5 food safe? Are all 2's and 5's food safe? Are others food safe, and how can you tell by looking?
