The raw material for coffee cups is commonly used as coated paper in coffee cups, which can be divided into double coated paper and single coated paper. The thickness of the coated paper commonly used ranges from 218 grams to 300 grams. The thickness of corrugated paper required for coffee cups varies from 280 grams to 340 grams. A coffee paper cup is a type of paper cup used to hold coffee, which looks better than a regular paper cup. The most commonly used is a paper plastic cup, with a layer of paper on the outside and a layer of coated paper on the inside, which is a type of inner polyethylene plastic film. Although the outer layer is paper, it is the inner plastic film that comes into contact with food. Therefore, there is controversy over whether this cup is defined as a disposable paper cup or a plastic cup. In terms of testing, both paper and plastic quality are tested. Without wax, people may feel that paper cups are safe. In fact, it has the most risk factors. The hygiene hazards of outer paper are very prominent. If the outer layer contains water, mold will form. Paper cups stacked together will inevitably contaminate the inside if there is mold on the outside.
When using paper cups, be sure to check if they become damp and moldy.
1. Advertising paper cups are divided into cold drink cups, hot drink cups, and yogurt cups according to their purpose. A cold drink cup, as the name suggests, is a paper cup that can hold cold drinks. Cold drinks have a characteristic that they need to be frozen or refrigerated, and the safe use temperature is 0-5. It has been decided that the entire paper cup can be waterproof. So, the body material of the cold drink cup is food grade wood pulp paper+PE film on the inner and outer surfaces. This can effectively prevent wood pulp paper from losing its original stiffness and toughness due to contact with moisture.
2. Disposable paper cups are mainly divided into three types: one is made of white cardboard, mainly used to hold dry things, and cannot hold water or oil; The second is the waxed paper cup. This cup is waterproof and thick because it has been soaked in wax, but as long as the temperature of the water in the cup exceeds 40, the wax will melt, and the wax contains Carcinogen polycyclic aromatic hydrocarbons; The third type is the paper plastic cup commonly used nowadays, with a layer of paper on the outside and a layer of coated paper on the inside. If the material used for production is not good or the processing technology is not up to standard, harmful substances will be generated.
3. The disposable paper cups currently sold in the market and commonly customized advertising paper cups are mostly PE coated paper, which is coated with a layer of food grade PE film on the original paper. The film's function is to make the paper cup waterproof, and it can also be formed and used during the production of paper cups. As for the wax coated paper cups circulating on the internet, they have already been phased out, and our paper cup factory has never used them, and we have not seen any other paper cup factories use them.
After discussing the PE film of PE coated paper, let's talk about the most important raw material for disposable paper cups, which is base paper. At present, the main paper cup base paper in China is domestically produced, with a small amount imported. With the continuous improvement of production processes in paper mills, the quality of domestically produced paper cup base paper is basically on par with imported paper cup base paper.
