What is the reason behind the PP plastic box facing two different words? First, the current Hygiene Standard for Food Packaging Paper is a standard formulated in 1989. This standard defines the definition of fuzzy plastic packaging paper. There is no specific distinction between paper products, which are divided into outer paper and inner paper. Special requirements for instant noodle barrels, tea cups and other hot food, hot drinks paper packaging standards. Because of the ambiguity of standards, many manufacturing companies use recycled paper as the raw material to make use of the flaws in the standards and the lack of detection methods. The paper only detects the inner paper of the product but does not detect the outer paper. Test qualified phenomenon.

In the lighting problem of the PP plastic box in the workshop, it is necessary to consider the lighting conditions between the machine operating area, the color observation area, and each printing color group. In general, the operator can see the situation around the printing machine according to the lighting conditions. It is best to hang two rows of fluorescent lamps above the printer so that the vertical distance from the printer is about 70 cm. In this way, the lamps and printers form a certain angle, and the lighting effect will be very good.
