Debunking Plastics Myths


There’s a large portion of the population that continues to have misconceptions about plastic products. Some believe that plastics are bad for the environment and our health in general. Others believe that plastic is killing the world’s wildlife. Unfortunately, these and other myths are pushed on consumers by environmental activists, non-government organizations with specific agendas, and journalists who have failed to do their due diligence in regards to research.

Here, US Cast, one of the country’s leading manufacturers of cast acrylic tube and rods shares some proven truths about plastics so you can be a more informed consumer.

Myth #1: Six-Pack Rings are Dangerous to Wildlife

The Internet is filled with photos of wildlife entangled in six-pack rings and this is one of the most popular tactics used to argue that plastic is bad for the world’s wildlife. But, the truth is, since 1989, laws were passed that required six-pack rings to be 100% photodegradable. Today, six-pack rings are manufactured using a proprietary and proven resin that disintegrates in sunlight, after just a few days. In fact, in 2006, The Chicago-Sun Times reported that representatives from both the Sierra Club and Oceana state that six-pack rings are "not a major issue for them." In addition, the U.S. Department of Energy states on its Web site that "if an animal were to become entangled in [a] six-ring carrier, it could rip through the weakened pack to free itself."

Myth #2: Frozen Plastic Water Bottles Release Dioxins Into the Water

Many consumers mistakenly believe that freezing a plastic water bottle will cause chemical dioxins to enter the water contained within. The truth is most of the plastics used to manufacture beverage bottles do not contain the chemicals that produces dioxins. Even the FDA has reported, "We have seen no evidence that plastic containers or films contain dioxins and know of any reason why they would."

Further debunking this myth, dioxins are only produced during combustion at extremely high temperatures (generally 700 degrees Fahrenheit or more). They do not form at room or freezing temperatures.

Myth #3: Plastic Food Wraps Contain Harmful Phthalates

Many consumers believe that plastic food wraps contain phthalates, a class of additives commonly used in the production of flexible polyvinyl chloride (PVC or vinyl) products. The truth is plastic food wraps, packaging, and containers made in the United States do not contain phthalates. Modern food packaging and storage items are manufactured using adipates or citrates instead of phthalates in order to make them flexible.  

Myth #4: Microwaving Food in a Plastic Container or Wrap is Dangerous

Similar to the myth about freezing plastic, many people believe that microwaving food that’s stored in a plastic container or wrap will cause chemicals to leach into the food. The truth is, most of these products can be safely used in the microwave as long as they are used in accordance with the directions on their packaging or the container itself. In fact, many food-approved plastic wraps and containers are specially designed to withstand microwave temperatures. Before using, however, you should always check the item or its label to ensure it is microwave-safe.

Myth #5: The Number on the Bottom of a Plastic Container Indicates How It Should Be Used

The number displayed on the bottom of most plastic containers and bottles is the product’s resin identification code. While many people believe this number indicated how the product can be used, it actually indicates a specific kind of plastic material used in the product’s manufacturing. This is a myth that can have potentially dangerous results, as resin identification codes do not provide guidance on the safe or intended use of the product.
