While the chemicals used in Saran Wrap are generally considered safe, there are some potential health risks to be aware of:
- Chemical leaching: when chemicals from the plastic wrap leach into food, especially when the wrap is heated or comes into contact with fatty or acidic foods.
- Microplastics: small plastic particles that can be ingested when eating food wrapped in plastic wrap.
Chemical Leaching
Chemical leaching is a concern when using plastic wrap, especially when heating food or wrapping fatty or acidic foods. Some studies have shown that chemicals from plastic wrap can leach into food, especially when the wrap is heated in the microwave or oven.
- A study published in the Journal of Food Science found that when plastic wrap was heated in the microwave, chemicals from the wrap leached into the food.
- Another study published in the Journal of Agricultural and Food Chemistry found that when plastic wrap was used to wrap fatty foods, such as meat and cheese, chemicals from the wrap leached into the food.
Microplastics
Microplastics are small plastic particles that can be ingested when eating food wrapped in plastic wrap. While the health risks associated with microplastics are still being studied, some research suggests that they can cause physical harm and inflammation in the body.
- A study published in the journal Environmental Science & Technology found that microplastics were present in a variety of foods, including salt, sugar, and beer.
- Another study published in the journal Nature found that microplastics were present in the gut of humans and animals, and that they could cause physical harm and inflammation.
Minimizing Your Exposure to Harmful Chemicals in Saran Wrap
While the health risks associated with Saran Wrap are still being studied, there are some steps you can take to minimize your exposure to harmful chemicals:
- Use alternative wrapping materials: consider using alternative wrapping materials, such as beeswax wraps or aluminum foil.
- Avoid heating food in plastic wrap: avoid heating food in plastic wrap, especially in the microwave or oven.
- Choose BPA-free and phthalate-free products: choose products that are labeled as BPA-free and phthalate-free.
- Use plastic wrap in moderation: use plastic wrap in moderation, and consider using it only for short-term food storage.
Alternative Wrapping Materials
If you’re concerned about the health risks associated with Saran Wrap, consider using alternative wrapping materials, such as:
- Beeswax wraps: a natural, reusable wrapping material made from beeswax and cotton.
- Aluminum foil: a durable, non-toxic wrapping material that can be used for food storage.
- Parchment paper: a non-toxic, biodegradable wrapping material that can be used for food storage.
Conclusion
While Saran Wrap is a convenient and widely used product, it’s essential to be aware of the potential health risks associated with its use. By understanding the composition of Saran Wrap, the potential health risks, and taking steps to minimize your exposure, you can make informed choices about your food storage options. Remember, it’s always better to err on the side of caution when it comes to your health and the health of your loved ones.

What is Saran Wrap made of?
Saran Wrap is a type of plastic wrap made from a combination of polyvinyl chloride (PVC) and polyethylene. PVC is a synthetic polymer that provides the wrap with its flexibility and clinginess, while polyethylene adds strength and durability. The exact composition of Saran Wrap may vary depending on the manufacturer and the specific product.
It’s worth noting that Saran Wrap also contains additives such as plasticizers, which help to improve its flexibility and prevent it from becoming brittle. Some of these additives have raised concerns about potential health risks, which we’ll discuss in more detail below.
Does Saran Wrap contain BPA?
No, Saran Wrap does not contain bisphenol A (BPA). BPA is a chemical that was previously used in the production of polycarbonate plastics and epoxy resins, but it has been largely phased out due to concerns about its potential health risks. Saran Wrap is made from a different type of plastic that does not contain BPA.
However, it’s possible that some older or generic versions of plastic wrap may contain BPA. If you’re concerned about BPA, it’s a good idea to check the packaging or manufacturer’s website to confirm that the product is BPA-free.
