Bark chemicals from Shasta red fir as stiffening agents for corrugating medium

Creator:: Oregon Forest Research Center
Abstract:: In these tests, phenolic constituents from bark of Shasta red fir were found ineffective as stiffening agents for corrugating medium. Other means of application, however, may be effective. Gum from inner bark of Shasta red fir was not so effective as a beater additive as was locust bean gum, but...
