The mechanical ease of folding crease lines is critical to automated carton erection. The creasing quality of carton board, or “creaseability”, describes the range of press conditions over which a board will fold effectively. A good carton fold should be free from fold cracking or liner splitting and show good rib formation.
A custom creasing study, combined with board and crease stiffness testing, can help evaluate and specify folding boxboards and white-lined chipboards for high-speed carton applications.
Standards and accreditation
Smithers can assess the creasing quality of carton boards in accordance with BS 4818.
