How big is a 300 ml cup?

A 300ml cup is as big as two disposable paper cups. Or the cans are about the same size. This type of cup is often encountered in hotels or guesthouses. Some hotels use it as a beer cup, and the 300 ml glass cup is relatively large. If it is a thermos cup with a capacity of 300 ml, it is often used in our daily life.

Classification of disposable paper cups

There are usually three kinds: white cardboard cups, waxed paper cups and paper-plastic cups. As the name implies, white cardboard cups are made of white cardboard, but because they are not waterproof and have low circulation rate, wax paper cups and wax layers can be waterproof, but they will dissolve and precipitate harmful substances at high temperature, so it is best to use them below 40 degrees.

Paper plastic cups have the widest circulation rate. The inner layer or the inner and outer layers are coated with dissolved PE, which is waterproof. The high temperature resistance is about 105 degrees, and it can be filled with hot water. If the temperature is too high, the plastic PE film will dissolve harmful substances.

Single-layer paper cup is a kind of disposable paper cup, also called single-sided coated paper cup, which is the layer with smooth pe coating inside the paper cup. Generally used for drinking water, convenient for people to drink. Made of food-grade wood pulp paper and food-grade PE film.

As the name implies, a double-layer paper cup is a paper cup with two layers. The quality of double-layer paper cups is better than that of single-layer paper cups. Double paper cups are also more durable than single paper cups. It can also be used to hold hot drinks, such as hot coffee.
