Types Of Disposable Paper Cups

Easy to carry and use, inexpensive paper cups are common drinking tools in many homes and public places.

Types of disposable paper cups: The general raw materials of paper cups are: food grade wood pulp paper + food grade PE film. Paper cups are divided into cold drink cups, wholesale hot drink cups and yogurt cups according to their uses. Cold drink cup, as the name implies, is a paper cup that can hold cold drinks. Cold drinks have a characteristic that they need to be frozen or refrigerated. The safe operating temperature is 0℃ to 5℃. Determines that the whole paper cup can be waterproof. Therefore, the body of the cold drink cup is food grade wood pulp paper + PE film on the inner and outer surface. This can effectively prevent the wood pulp paper due to contact with water and lose the original stiffness and toughness.

The Raw Material Of Disposable Paper Cup

The inferior paper cup adopts recycled polyethylene, which will produce cracking changes and many harmful compounds in the reprocessing process, and it is easier to migrate to water in use. Professor Zhang Qinfa, the expert of food packaging materials of food College of South China Agricultural University, once pointed out that paper cups are produced in order to achieve water-proof effect, they can be coated with a layer of polyethylene water-proof film on the inner wall. Polyethylene is the safest chemical in food processing. However, if the material selected is not good or the processing process is not satisfactory, polyethylene may oxidize to carbonyl compounds during the process of hot melting or application to the paper cup. Carbonyl compounds do not volatilize at ROOM temperature, but when a paper cup is filled with hot water, they may evaporate, so people will smell funny. From the general theoretical analysis, long-term intake of this organic compound, the human body must be harmful.

Use Of Disposable Paper Cups

Inferior paper cups are made of recycled polyethylene, which will produce cracking changes in the reprocessing process and produce many harmful compounds, which are easier to migrate to water in use.

Disposable Paper Cup Design

Try not to make a paper cup design and use full color paper cup. Full version of the color of the paper cup ink piled up too heavy, and the paper cup produced directly for sealing packaging. Solvent ink in the drying process of the release of organic compounds, alcohol wetting liquid isopropyl alcohol, the volatile gas coating are harmful to human health. In the sealed space, the base color of disposable fruit cup containers covers the whole body of the cup. Near the mouth of the cup, when we drink water from the paper cup, our lips will touch the mouth of the cup to a certain position, which will easily bring the above various chemicals into the body with the liquid and affect our health. Therefore, we generally recommend that customers should not design a full version of the color when designing paper cups, and the smaller the color block, the better. Also close to the mouth of the cup should not design graphics, especially block ink. Otherwise it will have the same bad effect. The bar shape near the bottom of the cup, the text design should be lifted 5mm. Because after the cup piece on the machine, the bottom 5mm of the cup should be pressed to ensure the firmness of the bottom of the cup. But after the high temperature and pressure of the machine, it is easy to make the graphics and text near the bottom of the cup, affecting the appearance. Therefore, in the design of graphics near the bottom of the cup text bar pattern should be lifted according to the height of the bottom of the cup about 5mm.
