Some small tips to help you evaluate the quality of salad bowls (food container) you get at your hand:
First, appearance. The raw wood pulp of qualified paper bowls does not need to be bleached, so the paper is slightly yellow in color, and there will be no blue spots under ultraviolet light. Inferior paper bowls(cups) are often processed from recycled paper and need to be bleached. The paper bowls(cups) of this paper will look very white. Also the paper is a secondary process of recycled paper so the fibers are relatively short, so the paper is rough and tough. Ultraviolet radiation will cause blue spots of fluorescent agent.

Second, smell. The PE coating of paper bowls (cups) produced by standard manufacturers are all colorless and odorless, and water-based inks are mostly used for printing so there is no peculiar smell. And there are 15mm blanks on the top and bottom of the paper cup that will not be printed. These are specified in detail in the national product quality standards. Inferior paper bowls (cups) often have an abnormal smell.

Third, look at the bottom of the cup. The leakage proof performance of a paper bowl (cup) depends on whether the knurling at the bottom of the cup is even and firm. In addition, standard manufacturers will print the production license number or QS number on the bottom of the paper bowl (cup) to ensure the entire quality control process.
