Not all paper cups and plates are plastic-free

Most disposable paper cups and plates contain sneaky plastic liners.

Whenever you are drinking from a paper cup at the office or at home, you are likely still consuming microplastics.

Most paper cups have plastic polyethylene (PE) liners to retain heat and repel liquids. Unfortunately, PE is one of the most abundant contributors to microplastics at a global scale, according to a study from the University of Barcelona in 2019.

Some paper plates also have plastic coatings containing PFAS, or ‘forever chemicals’.

Similar to paper cups, most paper plates that are leak- and stick-resistant have a glossy, plastic finish that can leach harmful chemicals into your food.

Paper plates, with plastic coatings, are especially dangerous when topped with hot foods or when used in a microwave.

Paper coffee cups leach microplastics at accelerated rates in contact with hot liquids.

Indifferent to paper cups used for water or cold liquids, paper coffee cups are lined with the same exact plastic.

Microplastic shedding from plastic containers is increased when exposed to piping hot liquids. A research study in 2021 found millions of plastic particles and other harmful chemicals in hot liquids contained by plastic bottles and linings, even more than what is observed in room temperature liquids.

How to avoid microplastics with plastic-free solutions.

Limiting your usage of single-use plastic-lined paper cups and plates are a great way to reduce your daily microplastic intake, but if you want microplastic-free storage of your favorite drinks on the go, consider travel mugs and bottles made from safe materials.
