Paper cups are a sort of throwaway packaging. More than 80% of the beverages supplied in the food and beverage business are packaged using this popular product type. So, what is the ideal option for paper cups at cafes and convenience stores, particularly paper cups for hot water? Read on in the following article.
Can all type of paper cups be used with hot water?
Not all types of paper cups can be used with hot water. Paper cups that are specifically designed for hot drinks are usually made with a special coating that can withstand high temperatures. This coating prevents the paper from becoming soggy or breaking down when it comes into contact with hot liquids.

There are many different types of paper cups for hot water, but the most frequent are:
- Single-wall paper cups: The most economical alternative, these cups are comprised of a single layer of paper.
- Double-wall paper cups: These cups are made up of two layers of paper with an insulating layer in between. As a result, they are more resilient to heat and more long-lasting than single-wall cups, allowing hot water to stay hotter for longer.
- Ripple-wall paper cups: These cups have a textured surface that improves grip and decreases moisture. Because of this, they are a fantastic choice for hot water because they are less likely to slip out of your hand or drop.
- Sleeve cups: These cups have a separate sleeve that fits around the cup to provide insulation. This makes them a good choice for hot water, as they are less likely to burn your hands.
- Sleeve cups: Insulation is provided by a separate sleeve that goes around the cup. This makes them a suitable choice for using hot water because they are less prone to burn your hands.
How paper cups can be used with hot water?
To withstand hot water or other hot beverages, paper cups must meet a number of requirements in terms of materials, construction, and, most importantly, the coating or lining inside the cup.
Paper Cups for hot water materials
Here are some materials popularly used:
- Paperboard: The cup's base is made of high-quality paperboard, which provides strength and rigidity.
- Polyethylene (PE) or Polypropylene (PP) Coating or Lining: These coatings operate as a barrier, preventing hot liquids from coming into direct contact with the paper and softening or breaking it down.
- Water-based adhesives: Adhesives are used to bind the multiple layers of paperboard together and to adhere the coating or lining.
Paper Hot Cups construction
When it comes to constructions, paper cups for hot water use these constructions as below:
- Single-walled: Using a single layer of paperboard. On the other hand, they are produced with a specific coating or liner that can resist high temperatures.
- Double-walled: Double-walled cups feature two layers of paperboard with an air space between them. This helps to insulate the cup and keep your drink warm for a longer period of time. This type of construction needs also a lining or coating inside.
- Ripple-walled: Ripple-walled cups have a corrugated surface that adds insulation and grip. Moreover, they are less likely to leak than paper cups with a single wall.
Coating and lining in disposable paper cups dangerous?
Disposable paper cups used for hot water must have a lining or coating. This is because hot water might cause the paper to break down and leak.The coating and lining are made of:
- Polypropylene (PP) lining: PP is a popular choice for paper cup linings because it resists heat and offers a strong moisture barrier.
- Polyethylene (PE) coating: Another frequent option that offers similar heat resistance and moisture barrier capabilities is PE coating.
- Plant-based coatings: Some paper cups are covered with plant-based materials, such as sugarcane-derived bioplastics. Because of their eco-friendliness, these coatings are becoming more popular.
These coatings and linings are subjected to extensive testing to verify that they meet food safety regulations and do not pose any health risks. Their purpose is to stop leaks, enhance heat resistance, and give drinks a smooth, non-absorbent surface.
Heat resistance of paper cups
Paper cups can withstand to maximum temperature?
Paper cups' heat resistance varies based on their construction and materials. Paper cups typically have a maximum temperature tolerance of 195 degrees Fahrenheit (90 degrees Celsius). This means they can retain hot water and beverages securely without leaking or breaking down.
However, it is important to note that the heat resistance of paper cups can be affected by several factors, including:
- The type of paper cup: Single-walled paper cups are generally less heat-resistant than double-walled paper cups.
- The coating or lining of the paper cup: Cups with a polyethylene (PE) or polypropylene (PP) coating or lining are more heat-resistant.
- The temperature of the hot liquid: The longer the hot liquid is in the cup, the more likely the cup is to leak or break down.
Here is a table that summarizes the heat resistance of various types of paper cups:
Paper Cup Type
Single-walled with PE or PP coating or lining
Hot beverages up to 176°F (80°C)
Single-walled with plant-based coating
Hot beverages up to 149°F (65°C)
Double-walled with PE or PP coating or lining
Hot beverages up to 194°F (90°C)
Double-walled with plant-based coating
Hot beverages up to 194°F (90°C)
Will paper cups containing hot water burn the user's hands?
When filled with hot water, paper cups will not burn your hands. However, if the cup is overfilled or the hot water is really hot, a burn might happen. It's crucial to do the following to avoid burns:
- Use cups marked "hot drink cups" or "heat resistant cups."
- Avoid packing cups too full.
- Use caution while handling cups, particularly when they are first filled with hot water.
- If the hot liquid is extremely hot, use a double-wall cup or a sleeve.
Paper cups for hot water is microwaveable?
Not all paper cups can be microwaved. Look for a "microwave safe" sign on paper cups if you're not sure if they can be microwaved.
Here are some more tips regarding microwave safety while using paper cups:
- Just half of the liquid should be in the cup because it will expand as it becomes hotter.
- Place the cup in the microwave's center to ensure equal heating.
- Avoid heating up a cup in the microwave for longer than three minutes since this can lead to overheating or damage.
- The cup will be hot when it comes out of the microwave, so use a potholder to remove it.
How long a paper coffee cup can hold hot water?
The amount of time a paper cup can hold hot water varies on the type of cup and the temperature of the hot water. Hot water in paper cups with one or two walls will usually stay hot for 10 to 15 minutes, while hot water in cups with two or more walls will stay hot for 20 to 30 minutes.
The best paper cups for hot water for coffee shops and convenient stores
As a result, coffee shops and convenience stores have a variety of paper cup options for use with hot water. However, before making their selection, coffee shops and convenience stores should consider a variety of factors, including:
- User-friendly: When used with hot water, the lining and coating comprised of PE and PP can emit some dangerous compounds. Consequently, applying a coating made of plant-based material—also referred to as PLA or bioplastic—is the best option.
- Sustainability: Paper cups are more environmentally friendly than plastic cups because they are made up of paper. To be more environmentally friendly, consider a cup with a coating and lining made of PLA, a bio-plastic that breaks down naturally over time without releasing dangerous components.
- Cost: Single-wall paper cups are typically less expensive than double-walled. However, the heat resistance of a single wall is frequently lower. Furthermore, different sizes have different prices. Choose the proper material and size based on the sort of beverage that your business offers.
