Paper GSM Tester measures the weight and quality of packaging materials. It helps check the strength of paper and cardboard used in boxes, cartons, and other packaging. GSM (grams per square meter) testing ensures consistent thickness and durability, preventing weak packaging that may tear or break. Industries like food, shipping, and retail use this test to maintain high-quality standards. Proper testing reduces material waste and improves product safety during transport and storage. Regular GSM testing helps manufacturers produce strong, reliable packaging that meets industry requirements
