the migration of aluminum (al) from aseptic laminated paperboard packages was studied by monitoring the al content of orange juice (plain juice, no additives) filled into such packages and stored at ambient temperature (23ºc) for up to 1 year. analytical procedure includes mw-assisted digestion of orange juice with concentrated nitric acid followed by determination of al concentration by double-...

Alkenyl succinic anhydride (ASA) is a sizing agent. The wettability of paperboard decreases when ASA applied. efficacy in board can be reversed under certain conditions, making the paper more hydrophilic and lesser quality/value. Although it broadly known that size reversion due to autooxidation presence oxygen air, environmental parameters initiate or catalyze this reaction are not well unders...

On the basis of data from 2000 to 2010, we investigated the separate effects of the uptake of forest certification and the usage of recycled paper on imports of paper and paperboard into Germany and the United States. Using panel data methods and based on a conventional Armington trade model, we find that the effects of two main forest certification schemes—the Programme for Endorsement of Fore...
