Knowing which microwave-safe containers are suitable is essential for the safe use of this appliance. This applies not only to the catering industry but also to home use, as containers must be heat-resistant and preserve the quality of the food.
As we know, the microwave is a great ally for preparing and reheating meals quickly and easily—especially when offering takeaway food that needs to be reheated in the same container it was delivered in.

Types of Microwave-Safe Containers
A container is considered microwave-safe when it can withstand high temperatures without being damaged. Below, we’ll explain each type based on its material and composition:
CPET Containers
Crystallised Polyethylene Terephthalate (CPET) is a material suitable for use in microwaves and ovens, as it retains its shape at high temperatures.
It is highly impact-resistant at low temperatures and forms an effective barrier against water, oxygen, and carbon dioxide.
PP Containers
Polypropylene (PP) is part of the polyolefin family and is used in various applications, including food packaging. One of its main advantages is its strong resistance to both heat and cold.
This material is commonly used for takeaway containers, as it features a protective barrier that prevents food from leaking out.
PP is microwave-safe because it doesn’t release harmful substances into the food and maintains its shape during heating.
HDPE Containers
HDPE (High-Density Polyethylene) is known for its high strength and is often used to produce sealing films for food containers.
It is microwave-safe due to its durability, heat resistance, and low production of water vapour and odour transmission.
Bagasse Containers
Bagasse containers are sustainable and eco-friendly, made from renewable resources. They are suitable for both hot and cold foods and are safe for use in microwaves.
Some common renewable sources include:
Sugarcane Bagasse Containers
Made from the waste left after extracting juice from sugarcane stalks, bagasse is rich in cellulose and has a paper-like texture, usually white.
Sugarcane bagasse containers are microwave-safe, allowing food to be heated without risk.
Wheat Fibre Bagasse Containers
This type of bagasse is derived from the plant residue left after separating wheat grains from the stalks. These residues are used to create eco-friendly containers, typically in a light brown tone.
They are also microwave-safe, liquid-resistant, and an excellent sustainable option for your business.
Paper and Cardboard Containers
Paper and cardboard containers, like bagasse options, are a popular and eco-conscious choice today. They come from renewable sources and are suitable for both cold and reheatable foods.
These containers are microwave-safe and ideal for various uses.
Bamboo Containers
Bamboo is another microwave-safe material thanks to its high heat resistance. Its structure takes longer to heat up than plastic, making it a safe option.
Bamboo does not conduct heat easily, making it durable and safe for reheating food in the microwave.
At Greenuso, you’ll find a wide range of microwave-safe containers, all 100% sustainable, compostable, and recyclable, to help promote environmental responsibility.
