⒈Remove label traces on the carton

Cover the carton with a dry towel, and then iron it a few times with an electric iron. The label will automatically fall off. If there are labels on the paper, you can put it in the printer, and then use WORD or other software to print a blank document on the paper with labels. The labels will automatically fall off. If it doesn't work, try a few more times.

I learned it in the company, and it works every time.

I wish you early success!

⒉ Apply some wind oil essence and it will be easy to tear off after it penetrates.

Blow the hot air of a hair dryer on the label for a while, and it can be peeled off immediately without leaving any traces.
