Instant Pots are electric pressure cookers that have become increasingly popular. They are versatile and convenient for cooking a variety of dishes, from soups and stews to cakes and bread. While Instant Pots offer many benefits, one common concern is the safety of using plastic containers or bags inside the appliance. Some people question whether plastic can be used in the Instant Pot for pot-in-pot cooking or making yoghurt, as plastic is known to melt or leach chemicals when heated. Official Instant Pot guidelines advise against using plastic, as it may melt and cause damage or injury. Instead, they recommend using food-grade containers made of glass, silicone, or metal, ensuring they are pressure-safe to prevent explosions or shattering. Some users also express concerns about plastic odours and chemicals potentially tainting food, opting for plastic-free alternatives or all-metal pressure cookers.

What You'll Learn
Plastic bags are not recommended due to melting and chemical leaching
While it is possible to cook with plastic bags in some circumstances, it is not recommended that you use them with an Instant Pot. This is due to the potential for melting and chemical leaching.
Firstly, plastic bags can melt when exposed to high temperatures. Ziploc bags, for example, will melt at around 176°F (80°C). The Instant Pot can exceed these temperatures, reaching beyond 212°F (100°C). Therefore, there is a risk that a plastic bag placed inside an Instant Pot could melt. This could result in the food becoming contaminated.
Secondly, even if a plastic bag does not melt, there is still a risk of chemical leaching. A 2011 study found that most plastics on the market, including those advertised as BPA-free, release non-BPA chemicals when heated. These chemicals can disrupt hormone activity. Therefore, using a plastic bag in an Instant Pot could potentially result in harmful chemicals leaching into your food.
Some people argue that the Instant Pot uses gentle heat and that the risk of chemical leaching is low. However, it is important to remember that the pressure cooker function of the Instant Pot can reach temperatures above 212°F (100°C). At these temperatures, there is an increased risk of both melting and chemical leaching.
Overall, it is best to avoid using plastic bags in your Instant Pot. Instead, use alternative materials such as glass or metal, which are safer for cooking at high temperatures.

Plastic bags can be replaced by glass containers, which are safer
While it is not recommended to place a plastic bag in an Instapot, glass containers can be used as an alternative. Glass is a safer option as it does not leach toxic chemicals into food products like plastic does, especially when exposed to heat. Plastic bags and containers can be replaced with glass containers, which are safer and more environmentally friendly.
Glass containers are inert, meaning they do not react with other chemicals. This keeps food and drink fresher for longer and eliminates the need for a chemical layer between the container and its contents. Glass is also superior in terms of durability and longevity, as it does not melt or discolour like plastic. It is also easier to clean due to its non-porous surface, preventing food particles from getting stuck and growing bacteria.
Glass is also better for the environment. It is 100% recyclable, and when recycled, it does not lose its quality like plastic does. Glass can be reused multiple times as it can be easily washed and sterilised, whereas plastic loses integrity each time it is recycled, making it less durable.
The production of glass is also more environmentally friendly than plastic. It produces five times less greenhouse gas emissions and requires only half the fossil fuels compared to plastic manufacturing. Additionally, potentially harmful substances are released during the production of plastic, such as methylene chloride and benzene, which are not present in glass production.
While plastic may be more economical in terms of production and shipping costs due to its lightweight nature, glass containers offer a safer and more sustainable alternative for storing food and other products. Glass containers are a healthier and more environmentally conscious choice, reducing the risk of toxic chemical exposure and minimising waste.

Plastic bags are not pressure-safe
Even plastic bags that are marked as BPA-free can release non-BPA chemicals that disrupt hormone activity when heated. A 2011 study found that most plastics on the market release these chemicals when heated, including those advertised as BPA-free. Therefore, it is not recommended to heat any form of plastic, even if it is marketed as safe for cooking.
Additionally, plastic bags can be unstable when heated and may leak or tear, contaminating the food inside. This is especially true if the bag comes into contact with the sides or bottom of the pot, which can cause the bag to melt. Even if a plastic bag is designed for boiling, it may not be safe for use in a pressure cooker due to the higher temperatures and pressure involved.
Furthermore, the pressure cooker function of an Instapot can create conditions that promote the growth of harmful bacteria, such as C. botulinum, which causes botulism. To prevent the growth of this and other bacteria, it is important to avoid storing food in the "danger temperature zone" of 40°F to 140°F for more than two hours. This temperature range is well within the range of an Instapot's capabilities, so using a plastic bag in an Instapot could increase the risk of bacterial growth.
In conclusion, plastic bags are not pressure-safe and should not be used in an Instapot or any other pressure cooker. The high temperatures and pressure can cause plastic bags to melt, leak, or release harmful chemicals, potentially contaminating the food and posing a risk to your health. It is always best to follow the manufacturer's instructions and use only recommended containers and accessories when using a pressure cooker.

Plastic bags are not food-safe
Firstly, it is important to note that plastic bags are not designed for repeated use. They can become more prone to leaching with repeated use and cleaning. Leaching is when compounds from the plastic are released and mix with the food or liquid inside the bag. This can be dangerous, as some of these compounds are known to be harmful to human health. For example, a 2011 study found that most plastics on the market, even those advertised as BPA-free, release non-BPA chemicals that disrupt hormone activity when heated. Other chemicals found in plastics, such as phthalates, are known to cause health problems, including preterm birth, increased asthma risk, and neurodevelopmental disorders.
Additionally, plastic bags are not designed to come into direct contact with food. This is because they are not food-grade, meaning they have not been certified by a regulatory agency as safe for food storage. Food-grade materials undergo extensive testing to ensure they do not affect the colour, odour, or taste of food and can handle different storage conditions. Conventional trash bags are produced without food in mind, and there may be components that are potentially harmful to humans.
Furthermore, plastic bags should not be heated or cooked with, as this can cause the molecules to become unstable and blend into the food. This is true even for plastics that are labelled "microwave-safe," as this only indicates that the plastic will not be visibly damaged by heat, not that it will not leach. It is recommended to use glass, metal, or ceramic containers for cooking and storing food instead of plastic to avoid the risk of leaching.
Finally, it is worth mentioning that plastic is not environmentally friendly. Plastic waste can have a detrimental impact on the environment, and reducing plastic use is beneficial for sustainability.
In conclusion, plastic bags are not food-safe due to the risk of leaching harmful chemicals, the lack of food-grade certification, the instability of plastic molecules when heated, and the environmental impact of plastic waste. It is advisable to use alternative containers, such as glass or metal, for cooking and storing food to ensure safety and sustainability.

Plastic bags can be replaced by silicone bakeware
Plastic bags should not be used in an Instant Pot. The Instant Pot website specifically instructs users to ensure that there is no plastic attached to the appliance. In addition, some people advise against heating any form of plastic, even if the manufacturer says it is okay. This is because plastics can leach plasticizers and antioxidant additives over time, especially when heated.
Silicone products have become increasingly popular in recent years as an alternative to single-use plastic. They are very similar to plastic in appearance, durability, and use, but they do not have the same harmful environmental impact. Silicone is also more durable than plastic, which can lose its shape over time. This makes silicone a more sustainable option, as it generates less waste. In addition, silicone is easily cleaned with soap and water or in the dishwasher.
When using an Instant Pot, it is important to follow the safety instructions provided by the manufacturer. This includes ensuring that there is no plastic attached to the appliance and that it is placed on a stable, level surface away from combustible materials and external heat sources.
