Magnetic Refrigerator Sticker Test

Magnetic refrigerator magnets are made of soft glue magnets on the bottom and coated paper color-printed peritoneum on the top. They are mainly divided into PVC soft glue refrigerator magnets and coated paper printed refrigerator magnets. The back is usually glued with metal magnets or rubber soft magnets. Zhongke Testing carries out magnetic refrigerator magnet testing, and the test report has CMA qualifications.
