Plastics - bad ones and not so bad ones

I found the list of plastic containers that are really bad and some that are not as bad as others based upon the numbers that are on the bottoms of the containers.  It was a helpful site that I found this list on. The site is http://www.exrx.net/Nutrition/Disrupters.html

The ones I used today were #5s.  But, I did use cling wrap (a little) and that was bad.   Keeping up with all of the technical information about bad stuff and worse stuff is time consuming.  That is why I really want to organize my group of "friends, neighbors, family" to begin brainstorming how to make a bigger impact on our community.  I am still working out the bugs in my head and need to do some more research on this course of action.  Anyway, here is the information.

Worst Plastics
  • Type 3: Polyvinyl chloride (PVC)
    • Products
      • Shampoo bottles, food packaging, shower curtains, medical tubing and bags, vinyl upholstery, floor tiles, pipes, Reynolds Wrap and cling wrap for most grocery stores
        • Can pass from packaging into food, water, or cosmetics
        • Can be breathed in from curtains or pipes
    • Contain Phthalates
      • Phthalate give plastic its resilience and flexibility
  • Type 6: Polystyrene
    • One of the most widely used plastics
    • Two forms of polystyrene: inflated and non-inflated
        • Styrofoam®, a Dow Chemical Company trademarked product
        • meat trays, egg cartons
        • plastic utensils, some takeout containers, cups, bowls, plates
        • plastic models, packaging for shipping.
    • May leak styrene, especially when heated
    • Styrene is classified as a possible human carcinogen by the EPA and by the International Agency for Research on Cancer.
    • Polystyrene is not biodegradable
  • Type 7 Polycarbonate (PC), among other plastics
    • Polycarbonates
      • Reusable water bottles, dental sealants, inner lining of food cans
      • Have been used in baby bottles and "sippy" cups for kids
    • Can contain BPA which can leach into food and water
Possibly Better Plastics
  • Type 1: Polyethylene (PET or PETE)
    • Disposable containers for most bottled water, soft drinks, and juice, mouthwash, ketchup, peanut butter, jelly, etc.
    • Avoid reusing #1 bottles and jars because the plastic is porous
      • containers absorb flavors and bacteria that can't be cleaned out
  • Type 2: High Density Polyethylene (HDPE)
    • Cloudy or opaque plastic
    • Milk, water, and juice jugs
    • Bottles for shampoo and detergent
    • Cereal-box liners
  • Type 4: Low Density Polyethylene (LDPE)
    • Cling wraps, food storage bags, garbage bags, and grocery bags
    • Squeeze bottles
    • Coatings for milk cartons and hot-beverage cups
  • Type 5: Polypropylene (PP)
    • Cloudy or opaque plastic
    • Most Rubbermaid container, cloudy plastic baby bottles, deli soup containers
    • Containers for yogurt, margarine, ketchup and syrup
  • Bio-based Polymers (Biodegradable polyester)
    • Derived from renewable resources, such as corn, potatoes, sugar cane.
    • Can be composted in a municipal composter or in a backyard compost pile
    • Healthiest and most eco-friendly choice.
Alternatives
  • Food storage
    • Parchment or waxed paper
    • Glass and ceramic food storage containers
  • On the go
    • Paper plates, bowls, and cups made from sugar cane
    • Bio-plastic utensils made from plant starch
    • Stainless steel insulated storage container for hot foods
    • Stainless steel water bottles or Ball brand canning jar with lid

  1. I am glad to see that you have classed the two different types, anyone using plastic should always do so in a responsable mannor , we sell products that can be reused over a long period of time to minimise the affect it has
