Reading: Is Polypropylene Safe and BPA Free?
What’s polypropylene, and what’s it used for?
Polypropylene is a formative. Of the commercial plastics on the market today, polypropylene is considered one of the safest. It ’ second FDA-approved for food contact, so you ’ ll find polypropylene in food containers like those that hold yogurt, cream cheese, and butter products. Because it has a high heat tolerance, it ’ second besides much used in packaging of food that can be heated in a microwave. Some surgical devices and implants are besides made of polypropylene, and polypropylene fibers are normally used to weave area rugs for indoor and outdoor practice.
Is it safe?
Polypropylene, which is derived from petroleum, is considered by the Environmental Protection Agency ( EPA ) to be a safer option than some other types of plastics. It ’ s not known to cause cancer in humans, and it ’ s less flammable in fabrics than wool. It ’ mho crucial to note, however, that some newer research does point to perniciousness in certain polypropylene containers. The researchers in a 2019 study looked at many kinds of plastic in a wide crop of products. They found that the toxicity of a particular plastic varied dramatically from product to product because of each product ’ second manufacture process. In this study, researchers found that some polypropylene products affected androgen hormones and caused a toxic or stress response in cells. More research is needed, specially since plastics are chemically complex, and each product could have different effects. This research hasn ’ t changed the FDA ’ south or the EPA ’ s recommendations for the use of polypropylene.

Is it BPA free?
Bisphenol A ( BPA ) is a chemical used in the fabricate of polycarbonate plastics. It ’ randomness besides used in epoxy resins that coat the insides of displace goods and urine add pipes. BPA leaches into food and water supplies easily. More than 93 percentage of the urine samples examined in a CDC study contained BPA concentrations. Although the FDA has said that minor amounts of BPA are condom for humans, some environmental and health experts are concerned that vulnerability to BPA could lead to problems with brain development, immune function, learning abilities, generative disorders, and early health issues. The growing concern around BPA has led to the production of several types of BPA-free plastics. Polypropylene is one type of credit card that ’ s loose of BPA .
What are the other types of plastic?
To make it easier for consumers to recycle and for recycling facilities to process plastics, containers are labeled with a resin ID code. This code is identified as a number between 1 and 7 stamped on the bottom of a box and framed by arrows forming a triangle. Polypropylene ’ second number is 5. hera ’ s an at-a-glance guide to resin recycling codes :
|Name||Resin ID||Found in||What to know|
|Polyethylene terephthalate (PET)||1||Plastic water and drink bottles, condiment containers||Generally safe, but at high temperatures may leak a metal called antimony.|
|High-density polyethylene (HDPE)||2||Jugs and bottles, plastic bags||Releases low levels of chemicals that raise estrogen levels.|
|Polyvinyl chloride (PVC)||3||Sandwich meat containers, sturdy bags for bedding, toys||Can contain toxins such as DEHP, which the EPA says is likely to cause cancer in humans in high concentrations. May also contain dioxins, vinyl chloride, and other toxins that can cause birth defects, learning difficulties in children, hormonal dysregulation, and cancer.|
|Low-density polyethylene (LDPE)||4||Dry cleaner and bread bags, shrink wraps||Generally considered safe.|
|Polypropylene (PP)||5||Potato chip bags, diapers, yogurt containers||Generally considered safe.|
|Polystyrene (PS)||6||Styrofoam cups, egg cartons, packing peanuts, cigarettes||Styrene, a chemical believed to cause cancer, can leach out of polystyrene containers, though the amount of styrene in packaged foods is very low.|
|Other miscellaneous plastics||7||Oven baking bags, other plastic containers||This is a catch-all category for plastic that doesn’t fall into the other categories. It contains BPA and is generally not considered safe.|
Tips for safe plastic use
Because plastic is everywhere, eliminating it entirely is a tall order. here are some tips for reducing fictile practice, ampere well as using it more safely :
- Doctors don’t recommend heating food in plastic containers because heat increases the chances that chemicals will seep out of the container and into your food. Choose to heat food in glass or metal containers instead.
- Choose products marked “BPA-free” if you can. Try to avoid plastics that are marked with recycle codes 3 or 7, unless there’s a leaf beside the number (which indicates the plastic is BPA-free). There’s typically a higher risk that these plastics contain BPA and other potentially harmful chemicals.
- Discard any plastic containers you’ve had since before 2012. That’s the year the FDA banned the use of BPA in sippy cups, baby bottles, and baby formula containers.
- Avoid using plastic or coated roasting and steaming bags. Heat may cause chemicals to be released into your food from these products.
- Don’t refill plastic water bottles labeled with a resin recycling code 1. They are intended as single-use containers.
- Avoid handling cash register receipts coated with a shiny film. According to advocacy group Breastcancer.org, that shiny coating contains BPA.
- You may want to consider replacing your plastic serve-ware and storage containers with glass or metal alternatives over time. Although polypropylene remains a safer alternative to some other types of plastic, the manufacturing process for plastic products may not be good for the environment.
The bottom line
Polypropylene is a formative that ’ s used to make everything from rugs to sour cream containers. It ’ s broadly considered to be one of the safe plastics. The FDA has approved its use as a food container material, and there are no know cancer-causing effects associated with polypropylene. You can tell you ’ re using a polypropylene container if the numeral 5 surrounded by a triangle is on the bottom of the container. If you ’ re concerned about the hypothesis of chemicals leaching out of a polypropylene package, you can take some steps to minimize your exposure. Transfer food into a glaze or metallic container before you heat it, and don ’ thyroxine recycle containers that are intended as single-use packaging .
