Corrugated Board Manufacture Adhesive ---On the other side of the medium to glue outer linerboard e Final heating and cooling section ---Between two long, flat belts Trimming edges---Slit board to required width and length and stack Balanced construction---Outer and inner have identical grammage e Upgrading only one liner may gain performance Unbalanced constructions--- more problems with board wrappage Heavier liner is placed on the outside for better printing and on the inside for better compression strength
二. Corrugated Board ⚫ Manufacture: ⚫ Adhesive --- On the other side of the medium to glue outer linerboard. ⚫ Final heating and cooling section --- Between two long , flat belts. ⚫ Trimming edges--- Slit board to required width and length and stack ⚫ Balanced construction--- Outer and inner have identical grammage. ⚫ Upgrading only one liner may gain performance. ⚫ Unbalanced constructions --- more problems with board wrappage. ⚫ Heavier liner is placed on the outside for better printing and on the inside for better compression strength
