We're supposed to avoid plastics #3 (PVC), #6 (polystyrene), and #7 (polycarbonate). Polycarbonate is the plastic that is made from the chemical Bisphenol-A (BPA). And BPA has a bad rap because it's a hormone-disruptor.
Is BPA free Tritan plastic safe?
Eastman Chemical went a step beyond calling Tritan plastic BPA-free, setting off a legal challenge. The new standard may be "EA-free," which means free of not only BPA, short for bisphenol A, but also free of other chemicals that mimic the hormone estrogen.
How do I know if BPA is in my plastic?
Use glass or unlined stainless steel water bottles. Keep plastic containers labeled with a 1, 2 or 5; they do not contain BPA or other plastic chemicals of concern. Dispose of plastic containers labeled with a 7 inside the recycle symbol.
Although PETE does not contain BPA or Phthalates, it's always best to make sure that your water bottles are not temperature abused. PETE plastic should not be reused because cleaning detergents and high temperatures can cause chemicals to leach out of the plastic. Plastic #1 is only intended for one time use.
What Do The Numbers on Plastic Containers Mean?
- #1 – PET or PETE (polyethylene terephthalate)
- #2 – HDPE (high-density polyethylene)
- #3 – PVC (polyvinyl chloride)
- #4 – LDPE (low-density polyethylene)
- #5 – PP (polypropylene)
- #6 – PS (polystyrene)
- #7 – Other.
Getting to Know Your Plastics: What the 7 Numbers Mean
- Plastic #1: Polyethylene Terephthalate (PET)
- Plastic #2: High Density Polyethylene (HDPE)
- Plastic #3: Polyvinyl Chloride (PVC)
- Plastic #4: Low Density Polyethylene (LDPE)
- Plastic #5: Polypropylene (PP)
- Plastic #6: Polystyrene (PS)
- Plastic #7: Other.
The following items should not be placed into your recycling bin:
- Any glass contaminated with stones, dirt, and food waste.
- Ceramics, such as dishware, ovenware, and decorative items.
- Heat-resistant glass, such as Pyrex.
- Mixed colors of broken glass.
- Mirror or window glass.
- Metal or plastic caps and lids.

In its continuous search for the best materials for use in its products, Tupperware has found other materials with improved performance characteristics that have been approved by regulators to be BPA free to replace polycarbonate. As of March 2010, items sold by Tupperware US & CA are BPA free.
BPA stands for bisphenol A. BPA is an industrial chemical that has been used to make certain plastics and resins since the 1960s. BPA is found in polycarbonate plastics and epoxy resins. However, the Food and Drug Administration (FDA) has said that BPA is safe at the very low levels that occur in some foods.
Here are the seven standard classifications for plastics, and the recycling and reuse information for each type.
- #1 - PET (Polyethylene Terephthalate)
- #2 - HDPE (High-Density Polyethylene)
- #3 – PVC (Polyvinyl Chloride)
- #4 – LDPE (Low-Density Polyethylene)
- #5 – PP (Polypropylene)
- #6 – PS (Polystyrene)
The sheets of plastic you get in a Shrinky Dinks kit is polystyrene—the same stuff as recycled plastic #6, which is commonly used for those clear clamshell containers you see in cafeterias.
While the vast majority of Tupperware products are considered safe, for example, some of its food storage containers use polycarbonate (plastic #7), which has been shown to leach the harmful hormone-disrupting chemical Bisphenol A (BPA) into food items after repeated uses.
Polyethylene Terephthalate (PETE or PET) The "1" inside a triangle in a plastic bottle indicates PETE or PET which is Polyethylene Terephthalate. These bottles are commonly picked through curbside recycling programs in most countries.
Yet to find a Safe Plastic Bottle. As a replacement, many manufacturers now adopt another engineering plastic - polycyclohexane dimethyl terephthalate modified by glycol (PCTG). It has excellent toughness and good heat resistance at ~120˚C. It is food safe as granted by FDA, and so will not emit BPA.
Previous research has focused on plastics containing the chemical bisphenol-a (BPA). During that time regular PET plastic water bottles have maintained a reputation as safe, at least as far as human health is concerned. But new evidence suggests that PET, or polyethylene terephthalate, may not be so benign after all.
LDPE is one of the safer plastics, but recycle it – and limit waste by bringing reusable bags when you're shopping. CODE 5: PP (POLYPROPYLENE) Qualities: Hard but flexible. Common usage: Ice cream and yogurt containers, drinking straws, syrup bottles, salad bar containers and diapers.
Looks like I will be refilling water bottles for longer than a week. The FDA does note that reusing plastic water bottles without washing them could possibly harbor some bacteria. Plastics are by nature a sanitary material, but the FDA recommends that you wash the bottle out with hot soapy water between uses.
Many food grade plastic containers fall into the high density polyethylene — or HDPE — category. It has excellent chemical resistant properties making it suitable for a wide range of foods and other products. For example, most juice or milk containers and five gallon food buckets are made from HDPE.
It is considered “FDA approved as a food-safe substance” and is generally considered inert. Unfortunately, there hasn't been much research on silicone bakeware or silicone molds so while there isn't any evidence that it is harmful, there also isn't much evidence that it is safe.
♳ Plastic #1. Polyethylene terephthalate, also known as PETE or PET. Usually clear in color, the vast majority of disposable disposable beverage and food containers and bottles are made of #1 plastic. This plastic is picked up by most curbside recycling programs.
Items like these, as well as medicine bottles and some microwave-safe take-out containers, are typically made from #5 plastic, or polypropylene. This type of plastic is lightweight, yet durable and can withstand high temperatures, moisture and oil, making it ideal for food and other containers.
