Paper cups are a common way to store food, including dips, snacks, and liquid-based meals. However, have you ever considered whether meals in paper cups can be heated in an oven? Can a paper cup catch fire in the oven? Our article from today has the solution!
Common types of ovens and their temperature range
Common type of ovens
Although there are many different kinds of ovens, these are the most popular ones:
- Conventional oven: the most basic kind of oven is the conventional oven. They create heat with a heating element, and then radiation transfers the heat to the food. Compared to other oven types, conventional ovens are typically less expensive and simpler to operate. They might not be as effective as other kinds of ovens, though, and it can take longer for food to cook uniformly.
- Convection ovens: Its function similarly to regular ovens, but they additionally feature a fan to distribute hot air throughout the cooking chamber. Compared to a traditional oven, this aids in cooking food faster and more evenly. For baking and roasting, convection ovens work well because they may assist create crispy exteriors and moist interiors.
- Microwave Oven: Microwave ovens heat food using microwaves. Electromagnetic radiation, such as microwaves, can permeate food and vibrate the water molecules within. The food is cooked by the heat produced by this vibration. For quickly and easily heating up tiny foods like popcorn, frozen dinners, and leftovers, microwave ovens are highly efficient. However, they are not as suitable for baking and roasting because they can yield uneven results.
- Toasting Oven: Toasting bread, roasting vegetables, and reheating leftovers are common uses for little countertop ovens known as toasters. They are a good option for those who don't require a full-sized oven or for small kitchens.
Temperature range of oven

Heat resistance of paper cups
Is it safe to use paper cups for hot drinks?
Paper cups, which are made of paperboard and improved with a PE, PP, or PLA covering or lining, are versatile for holding hot or cold liquids without leaking or spilling. However, when handling hot beverages, it's essential to stick to the recommended temperature range to avoid consumer burns and adhere to safety regulations.

What happens when paper cup is heated?
Depending on the temperature and type of cup, several changes occur when paper cups are heated.
- Low temperatures: The cup keeps its firmness and flexibility.
- In moderate temperatures, a single-walled cup may collapse, soften, and lose its firmness.
- High temperatures: The risk of fire increases, the adhesive weakens, and the cup becomes brittle.
- Point of ignition: The cup quickly burns and catches fire.
What Are Temperature Limits of Paper Cups?
Paper cups are commonly used in everyday life. Each variety of them has a heat resistant limit based on the material and structure. The following table lists common paper cups along with their maximum heat resistance:
Paper Cup Type |
Heat Resistance Limit (°F) |
Description |
Single-Walled Paper Cups |
120°F (49°C) |
Basic, economical, for cold beverages, one layer of paperboard |
Double-Walled Paper Cups |
180°F (82°C) |
Enhanced heat resistance, two layers of paperboard with an insulating air gap, for hot beverages |
Polyethylene-Lined Paper Cups |
200°F (93°C) |
Thin layer of polyethylene plastic lining, heat and moisture resistance, for coffee, tea, and other hot drinks |
Wax-Coated Paper Cups |
220°F (104°C) |
Superior heat resistance and moisture protection, thin layer of wax on the inside, for hot drinks, soups, and hot chocolate |
Plastic-Lined Paper Cups |
250°F (121°C) |
Highest heat resistance, thicker layer of plastic lining, superior insulation and protection against heat and moisture, for coffee, tea, and hot chocolate |
What will happen if paper cups go in the oven?
Paper cups are made of the flammable material cellulose. Furthermore, it is apparent that paper cups are not appropriate for use with ovens when comparing the temperature range of ovens and the heat resistance limits of paper cups.
The following are some risks related to using paper cups in the oven:
- Fire: If paper cups are placed in an oven, they can quickly catch fire. This could result in a kitchen fire, which could harm your house and result in casualties.
- Smoke: When paper cups burn, toxic smoke is released into the atmosphere. Your lungs may be harmed by the irritants and chemicals in this smoke.
- Chemicals: Burning paper cups can cause dangerous chemicals to be released into the surrounding environment. Benzene, styrene, and formaldehyde are a few examples of these substances that are known to cause cancer.

There are certain specific types for baking, such as silicone-lined paper cups or wax-coated paper cups. Before baking, make sure the product is labeled as oven-safe.
Can we boil paper cup?
A paper cup should not be boiled. Generally speaking, paper cups are made to serve drinks; they are not meant to be subjected to hot temperatures, particularly boiling water. It is preferable to use a cup made of a heat-resistant material, such as glass, or ceramic. In addition, food can be reheated in a microwave-safe cup.
Can I microwave a cardboard cup?
It is possible to microwave a cardboard cup, however it is not recommended. Make sure the paper is microwave-safe before heating up any paper cups. Use a cardboard cup in the microwave only for cold or lukewarm food and only for a little amount of time if you must. It is not recommended to use it with hot food as this could ignite the cup. Also, keep an eye on the cup at all times when it's in the microwave.
In summary, due to differences in temperature range and heat resistance, paper cups are not suited for use with all types of ovens. Using paper cups in the oven can result in a variety of issues. When utilizing, extra care should be taken.
