Box Compression Strength Tester - X500/X1000 (ASTM / TAPPI / ISO / ISTA Compliant) by PackTest.com

A corrugated shipper / carton’s primary purpose is to protect the unit packaging inside and prevent any undue stress to reach the product. The carton has to withstand the stress of stack load in warehousing and transportation. If the carton is stronger than the stack load, the products will survive. If the carton is weak, the carton will collapse and pass on the load to the inner packs.

Carton Compression Specification = Stacking Load x Safety Factor.

Safety factor is usually between 3-7 and depends on a lot of factors including product fragility, product cost, distribution cycle, transit period, transportation methods, etc.

This test is a typical “Performance Test” and a good compression strength directly signifies a good carton.

Test Method :
The test specimen is placed between 2 parallel platens of a compression tester and pressed. The max load it can bear before the carton collapses is recorded as the Compression Strength.

Test Standard : TAPPI T-804 / ASTM D 642 / ISO 12048 / IS 7028 / ISTA6
