How to choose disposable paper cups?

1. Disposable paper cups are divided into cold drink cups and hot drink cups.

Disposable paper cups are paper containers made of wood pulp and then processed, and there are two kinds of coatings on the inner wall of paper cups, one is waxed paper cups, and the other is PE film-laminated paper cups.

Cautions:

Do not mix cold and hot paper cups.

Both types of paper cups are not suitable for alcoholic beverages, alcohol permeability is strong, easy to lead to leakage, the longer the leakage more.

Disposable paper cups should not be used repeatedly, the firmness will become lower.

1) Waxed paper cups
Waxed paper cups are paper cups coated with a layer of wax on the inner wall, used to isolate the paper cups inside the food or drinking water and paper containers in direct contact with the cups, and is now generally used as a cold drink cups.
It has been said that ‘Waxed paper cups should not be used for hot drinks because the wax layer on the surface will melt and get mixed into the food, affecting your health’.
This statement is actually not accurate, first of all, to make it clear that the regular qualified disposable paper cups coated with wax layer are edible wax, non-toxic, insoluble in water, a small amount of food into the body is able to be discharged.

However, the melting point of edible wax is really low, between 0° - 5° will be more stable. However, even with hot water, edible wax is still ingested in small quantities, so there is no need to panic as long as it is not used frequently.

Therefore, using waxed paper cups (cold drink cups) to fill hot drinks poses the biggest safety hazard, when the wax layer melts, the cup body softens and deforms after contact with water, and the water spills out and may scald yourself.

2）PE paper cups
Film (PE) paper cups is in the paper cups covered with a layer of film (PE), very smooth, can play the role of water and oil. PE is polyethylene, polyethylene is the safest chemical substances in food processing, that is, we often refer to as plastic.

This material is odourless, non-toxic and has a wax-like feel and little water absorption, so it is often used as a waterproof material. Its melting point is between 120° - 140°, while the boiling point of water is 100°, so it will not dissolve in water and is safer to use.

Most of the disposable paper cups on the market nowadays are single-layer lamination (PE) paper cups, that is, only the inner wall of the paper cup is lined with lamination, while the outer wall is not.

So it is not recommended to use for cold drinks, because it is easy to form condensation on the outer wall of the cup when containing cold drinks, condensation is easy to soften the cup, stiffness decreases, and the paper cup is easy to be deformed, resulting in the spillage of water.

In fact, the waxed paper cups on the market has been reduced a lot, most of what we see are film (PE) paper cups, if you want to drink hot drinks on the purchase of single-layer film paper cups, if you want to drink cold beverages, it is best to buy a double-layer film paper cups (the outer wall of the inner wall are coated with film).
