Disposable paper cups are paper containers made of wood pulp and processed into base paper. Generally, there are two types of coatings on the inner wall of the paper cups, one is waxed paper cups, and the other is PE coated paper cups. wholesale bagasse bowl
Can not mix hot and cold paper cups. Both paper cups are not suitable for alcoholic beverages. Alcohol has strong permeability and is easy to cause leakage. The longer the time, the more leakage.
Waxed paper cups.
Waxed paper cups are coated with wax on the inner wall of the paper cup to isolate the food or drinking water inside the paper cup from direct contact with the paper container. It is now generally used as a cold drink cup. Some people have said that waxed paper cups cannot be filled with hot drinks, because the wax on the surface will melt and mix into the food, affecting health. custom paper cups wholesale This statement is actually inaccurate. First of all, we must make it clear that the wax layer in the formal and qualified disposable paper cups is edible wax, which is non-toxic and insoluble in water. It can be excreted in a small amount of consumption. However, the melting point of edible wax is indeed very low, relatively stable between 0°-5°. However, even if you add hot water, edible wax will ingest a small amount of the body, so you don’t have to panic if you don’t use it frequently. Therefore, using a wax cup (cold drink cup) to hold hot drinks poses a major safety hazard.
The PE paper cup is covered with a PE film on the inner wall of the paper cup, which is very smooth and can be water and oil resistant. pla paper cups manufacturers Polyethylene is polyethylene, and polyethylene is a safe chemical substance in food processing, which is what we often call plastic. This material is odorless, non-toxic, feels like wax, has low water absorption, and is often used as a waterproof material. Its melting point is between 120-140°, and the boiling point of water is between 100°. single wall paper cup factory It is insoluble in water and safe to use. At present, most disposable paper cups on the market are single-layer coated (PE) paper cups. Therefore, it is not recommended to hold cold drinks, because condensed water is easy to form on the outer wall of the cup when cold drinks are served. The condensed water can easily soften the cup body and reduce its stiffness. The paper cup is easily deformed and causes water to spill.
In fact, the wax-coated paper cups on the market have decreased a lot. Most of the paper cups we see are coated (PE) paper cups. If you want to drink hot drinks, you can buy single-layer coated paper cups. If you want to drink cold drinks, you can buy it. Double-layer coated paper cup (the outer wall and the inner wall are coated with film). In waxed paper cups, conventional products use edible wax. wholesale pla lined cup Inferior products are likely to use industrial wax to reduce costs. Industrial wax contains impurities, and drinking can cause harm to the human body. In the coated (PE) paper cups, conventional products use polyethylene (PE) materials. Moreover, inferior products are likely to use recycled polyethylene to reduce costs. The recycled polyethylene will undergo cracking changes during the reprocessing process and produce a large amount of harmful compounds. It is easy to drift to the water during use, which is harmful to health.
