In order to alleviate the increasing demand for softwoods, oak and pine pulps in varying ratios were investigated for linerboard use in corrugated containers. It was found that oak could be used in significant amounts in linerboard stock and, thus, provide an outlet for this currently underutilized species. Upon evaluating the combined boards and assembled containers it appeared that, when properly fabricated, at least 25 percent oak could be included and still satisfy today's required carrier rules. Considerably higher percentage of oak could be tolerated based on actual box performance despite somewhat lower combined board burst values. Scoreline fracturing for boards of any oak-pine ratio can be eliminated by proper adjustment of scorewheel clearance and board moisture content. (Author).
