Slow Cooker Liners: What Are They Made Of?


If you’re a fan of slow-cooked meals but dread the clean-up afterwards, you may have considered using a slow cooker liner. But what are these liners made of? And how do you use them?

Slow cooker liners are made from a variety of materials, including nylon and polyester, which are often coated with a food-grade plastic or wax. This coating makes them non-stick and prevents food from sticking to the liner, which can make cleaning up after a slow-cooked meal much easier.


Another popular option for slow cooker liners is silicone. Silicone cooker liners are made from a food-grade silicone material that is non-stick and reusable. They’re great for those who want to avoid the environmental impact of disposable liners and want a more sustainable option.

Using a slow cooker liner is a simple process. First, ensure that your slow cooker is clean and dry. Then, unfold the liner and place it inside the slow cooker, making sure it covers the bottom and sides of the cooker. Add your ingredients and cook as directed. When you’re finished, carefully remove the liner and discard it, making sure to avoid any spills or drips.

While slow cooker liners can be a convenient option, it’s important to note that they’re not without their drawbacks. Some people have concerns about the potential health risks associated with cooking food in plastic, and others argue that they’re not environmentally friendly. Additionally, some slow cooker manufacturers advise against using liners, as they can interfere with the proper functioning of the cooker.


If you’re worried about the potential health risks, it’s important to note that slow cooker liners are typically made from materials that are considered safe for food contact. However, some people worry about the potential for chemicals to leach into their food, especially when the liner is heated for an extended period of time. To reduce your risk, you can look for slow cooker liners that are labeled as BPA-free or made from other materials that are considered safer for food contact.

Another potential concern with slow cooker liners is their environmental impact. Because they’re typically made from plastic or other synthetic materials, they’re not biodegradable and can contribute to landfill waste. If you’re concerned about the environmental impact of slow cooker liners, consider using alternative methods for easy clean-up, such as lining your slow cooker with parchment paper, using a non-stick cooking spray, or investing in a reusable silicone cooker liner.

It’s also worth noting that some slow cooker manufacturers advise against using liners, as they can interfere with the proper functioning of the cooker. If you’re unsure whether it’s safe to use a liner with your particular slow cooker, check the manufacturer’s instructions or contact their customer support for guidance.

In conclusion, slow cooker liners are made of various materials and can be a convenient way to make clean-up easier. However, it’s important to carefully consider the potential drawbacks and to follow any manufacturer’s instructions regarding their use. If you’re concerned about the potential health risks or environmental impact of using slow cooker liners, there are alternative methods for easy clean-up that you can consider, such as using a reusable silicone cooker liner.
