What type of material of plastic cup can be heated?

There are many types of plastic cups on the market, and each type has advantages and disadvantages. While some are ideal for keeping cold beverages, others can also handle hot ones if required.

So, if you’re looking for a cup that can be heated, then you’ll want to choose a heat-resistant material. Some of the most common heat-resistant materials used in plastic cups include polypropylene and polystyrene. These materials are both lightweight and durable, making them ideal for various settings. However, they can also be slightly more expensive than other types of plastic, making them non-suitable for budget-conscious manufacturers.

No matter what material you choose, select a cup marked with the “microwave safe” tag to ensure that the cup won’t melt or warp when exposed to high temperatures.

The 5 Best Plastic Materials to Make Plastic Cups

A variety of plastics can be used to make plastic cups. The five most common types are polyethylene terephthalate (PET), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), and Polystyrene (PS).

Each type of plastic has its benefits and drawbacks. For example, PET is robust, lightweight, and shatter-resistant. However, it is not as heat-resistant as other plastics. HDPE is a durable material that can withstand high temperatures but is not as transparent as other plastics.

LDPE is a flexible material often used for disposable cups and containers. It is not as rigid as other plastics and can easily puncture or tear. PP is a strong, rigid material that is heat-resistant and ideal for reusable cups.

Since the options are endless, it is essential to make an appropriate choice to ensure food safety and product quality standard. Here, we have mapped out the 5 best plastic materials used to create plastic cups. Check them out and pick wisely.

1.PET Plastic

Also known as polyethylene terephthalate, PET is a type of plastic often used to make disposable plastic cups. This plastic is solid and shatter-resistant, making it a good choice for cups that will be used only once and then thrown away. PET plastic is also clear, showing off your drink’s color.

In addition to PET, you can also opt for rPET, which is made from recycled polyethylene terephthalate material.


Polypropylene plastic is a type of plastic often used in manufacturing cups and other drinking vessels. This plastic is known for its durability and resistance to breakage, making it an ideal choice for products exposed to repeated use or rough handling.

Polypropylene cups can withstand high temperatures and are generally found in various sizes, colors, and designs, making them a versatile option for personal and commercial use.


High-Density Polyethylene, or HDPE,  is ideal for disposable plastic cups because it is strong and durable. HDPE cups can be used for hot or cold beverages and are available in various sizes. HDPE plastic is also recyclable, making it a more sustainable choice for disposable cups.

In addition, HDPE is lightweight and easy to transport, making it a convenient option for on-the-go drinking.


LDPE plastic is ideally suited for disposable plastic cups owing to its lightweight, durability, and inexpensive pricing. LDPE plastic is very strong and durable, meaning that it can withstand being used multiple times. In addition, LDPE plastic is also very light, making it easy to transport and store.


It is a synthetic aromatic polymer made from the monomer styrene. Polystyrene is a versatile and affordable material that has many benefits. It is lightweight and easy to work with, making it a popular choice for various applications.

Polystyrene is an excellent insulator, both thermal and acoustic. It is also moisture resistant, making it ideal for outdoor applications like disposable cups.

Why is polypropylene plastic ideal for Heated Plastic Cups?

Now that you know the plastic materials that can be used for making plastic cups, it’s time to throw some light on the option that can be heated. Well, it’s none other than Polypropylene cups.

While other plastics, like Polystyrene and Polyethylene, are also heat-resistant, Polypropylene cups are still the best for several reasons. Read on the page and find what makes PP plastic cups ideal and worth adding to your collection, especially if you want to heat them.

Versatile Temperature Range

Polypropylene (PP) cups can be used across various temperatures, making them ideal for various applications. For hot beverages, PP cups can withstand temperatures up to 331°F, and for cold beverages, PP cups can be used in temperatures as low as 32°F. This versatility makes PP cups ideal for coffee, tea, or soda.


These cups are microwave-friendly and can withstand temperatures up to 331 degrees Fahrenheit. This plastic is safe to use in a Microwave and won’t release harmful chemicals into your food. You can quickly reheat your coffee or tea without worrying about the cup melting or becoming deformed.


The next benefit of using PP plastic cups is that they are cost-efficient, so you don’t have to spend a fortune on them. They are a cost-efficient way to serve coffee and other hot beverages.

PP cups are durable and reusable, which reduces the need for disposable cups. These can be used in hot and cold beverage applications, making them a versatile option for any business.


Polypropylene cups are one of the lightweight options available on the market. This makes them ideal for use in a variety of settings, including those where space is limited. They can be easily carried around and are less likely to break if dropped.

In addition, they are often more stackable than other types of cups. This means they take up less space when stored, which can be helpful in small kitchens or other storage areas. Their stackable nature makes it easy to transport multiple cups at once without worrying about them tipping over and breaking.


We hope you are convinced of the many benefits of using polypropylene cups. These cups are heat-resistant and offer a versatile temperature range. Not only are they more microwave-friendly than other types of cups, but they are also more durable and reusable. If you are looking for a cup that will last a long time and help reduce your carbon footprint, then a polypropylene cup is the way to go.
