  Disposable paper cups is a paper container made of wood pulp and processed after making base paper. There are generally two kinds of coating on the inner wall of paper cup, one is waxed paper cup, the other is PE coated paper cup. The former is usually used for carbonated drinks, ice cream, ice water and other cold drinks, while the latter is usually used for hot milk, coffee, hot water and other hot drinks.

Disposable paper cups  Notes:
  Don't share hot and cold cups.
  Both types of paper cups are unsuitable for alcoholic drinks. Alcohol is permeable and tends to leak.
  Don't use disposable paper cups repeatedly. They will be less firm.
  
  The waxed paper cups
  The waxed paper cup is coated with a layer of wax on the inner wall of the paper cup to isolate the direct contact between the food or drinking water inside the paper container. It is commonly used as a cold drink cup now. It was once said that a waxed paper cup should not be used to hold hot drinks because the wax layer on the surface will melt and mix with food, which will affect health. This statement is not quite accurate. First of all, we should make it clear that the wax layer inside the qualified disposable paper cup is all edible wax, which is non-toxic and insoluble in water. A small amount of food can be discharged into the body. However, the melting point of edible wax is really low, between 0° - 5° will be more stable. But even in hot water, wax is consumed in small amounts, so there is no need to panic as long as it is not used regularly. Therefore, the biggest safety risk of using waxed paper cups (cold drinks cups) for hot drinks is that when the wax layer gradually melts, the cup body will soften and deform after contacting with water, and the water may spill out and burn oneself.
  
  Film (PE) paper cups
  Film (PE) paper cup is in the paper cup wall covered with a layer of film (PE), very smooth, can play the role of waterproof and oil. PE is polyethylene, and polyethylene is the safest chemical in food processing, which we call plastic.This kind of material is odorless, avirulent and feel like wax, water absorption is small, often be used as waterproof material so. It has a melting point between 120° and 140°, whereas water has a boiling point of 100°, so it does not dissolve in water and is safer to use. Now most of the disposable paper cups on the market are single-layer film (PE) paper cups, that is, only the inner wall of the paper cup has film, and the outer wall does not have. Therefore, it is not recommended to serve cold drinks, because it is easy to form condensate water on the outer wall of the cup when serving cold drinks. Condensate water tends to soften the cup body and reduce its stiffness. The paper cup is easy to deform and cause water to spill out. In fact, the wax coated paper cups on the market have been reduced a lot, most of what we see are coated film (PE) paper cups, if you want to drink hot drinks to buy single-layer coated paper cups, if you want to drink cold drinks, it is best to buy double-layer coated paper cups (the outer wall and inner wall have coated film)。
  
  Guides of choosing disposable paper cups
  First,buy regular brands, don't be greedy for price
  If you have the need to buy disposable paper cups, then go to the regular supermarket to choose well-known paper cup products. The vast majority of paper cup products circulating in regular shopping malls and supermarkets are qualified after inspection, and products of well-known brands usually occupy larger shelves.
  Second, read the product information carefully
  Look for the "QS" logo. According to the State Administration for Market Regulation, products such as paper food containers, including paper cups, must bear the "QS" mark before they can be sold. The packaging also indicates the material used (wax or PE) and the applicable temperature of the disposable paper cup.
  Third, watch the paper cup carefully
  Note: Observe whether the inner and outer surfaces of the paper cup are clean, have deformation, mildew, and whether the thickness is even. Good quality paper cup resilience is good, not a pinch on the soft.
  Pay attention to the principle of 15 up and 10 down for hot and cold paper cups. Because printed with the pattern of disposable paper cups on the graphite easy to fall off, that is not friendly to health. And the mouth of the cup is easy to touch lips, the bottom of the cup and worry about penetration. Therefore, there should be no printing within 15mm from the cup mouth and 10mm from the bottom of the cup body. This must be up to standard by the regular manufacturer.
  Take a sniff. If there's a pungent ink smell or other pungent smell, don't use it.
  
  The above is about how to choose disposable paper cups you should know the relevant information, grasp the basic situation in order to choose better and safer products. I hope to have some help to you through those product classification and notes,, and if you have any questions, welcome to leave a message.
