Why Don’t Crock-Pot Liners Melt?

Crock-pot liners offer convenient and mess-free slow cooking. But how can they ensure that the liner remains intact, given the heat that it is subjected to? Fortunately, crock-pot liners are made from a special type of plastic that is both heat-resistant and safe for use with food.

What are Crock-Pot Liners?

Crock-pot liners are special plastic bags designed for use with the popular slow-cooker appliance. They are designed to fit snuggly into a crock-pot, enabling easy cooking with minimal clean-up.

What Makes Crock-Pot Liners Heat-Resistant?

Crock-pot liners are typically made from a type of high-density polyethylene plastic and prepared according to the United States Department of Agriculture (USDA) food safety requirements. This material is chosen for its heat-resistance as well as its imperviousness to oil and fat. Additionally, it is able to withstand temperatures of up to 400°F (205°C) for extended periods.

Advantages of Crock-Pot Liners

Crock-pot liners offer several advantages when compared to other types of slow cooking vessels. These include:

  • Ease of Use: Crock-pot liners can be added to a crock-pot with ease, and removed quickly at the end of cooking.
  • Mess-Free Clean-up: Known for being mess-free, the crock-pot liner can be discarded with little effort.
  • Safe: Crock-pot liners are made with food-safe materials, making them a safe and healthy choice.


Crock-pot liners offer an easy and safe way to slow-cook food. Thanks to their heat-resistant plastic material, they can withstand high temperatures without melting. This makes them an ideal choice for slow cooking.
