The Problem of Raw Materials For Disposable Paper Cups and Food Bowls

In the past, the wax-coated paper cup was the most used. It was soaked in wax. It can only hold cold drinks, not oil things, because oil can dissolve wax. Wax melts at around 40°C, and wax contains carcinogenic polycyclic aromatic hydrocarbons.

Now the most commonly used is a paper-plastic cup, which is an inner polyethylene plastic film lined on paper. The plastic film is in contact with the food, so it is controversial whether this cup is defined as a paper cup or a plastic cup. In terms of testing, both paper and plastic quality are tested.

The paper cups are stacked together, and mold on the outside will inevitably contaminate the inside. When using paper cups, be sure to see if they become damp and moldy. 

Secondly, the ink printed on the outer layer generally has smell, if it is very strong irritating smell, then the ink may not meet the food safe standard. Many ink components contain benzene and toluene, and benzene is a recognized carcinogen.

We are using non-benzene inks when printed our bowls and cups. To make sure our products are safe for food package.

Some paper cups may be made of waste paper. In order to make the paper cups look whiter, manufacturers will use bleach during production. Some manufacturers may also use fluorescent powder to increase whiteness. According to national regulations, food paper is not allowed to use fluorescent powder. Therefore, the whiter the paper cup, the less safe it is.

If the plastic film on the inside is food-grade plastic, it can meet the national requirements. If industrial plastic is used, in order to increase the toughness and stiffness of the cup, the paper cup will add plasticizer. Hygienic conditions cannot be guaranteed if the dosage is too high or illegal plasticizers are used.
