The ink selected by the plastic packaging during the printing process will also cause some harm to the environment. Toxic inks change color when exposed to oil. Therefore, it can be smeared with oil at the time of purchase to see if it is safe to print.

Second, look at the bearing capacity of coffee packaging
The state has regulated the weight of plastic bags, and plastic bags must be able to withstand their own weight. The simplest method of detection is to put certain things in and walk around the plastic bags to see how long the bags can last. Bags with insufficient capacity often break during use, so the number of uses will increase and waste will increase.
