"This again shows a combination of factors at work," says Dr. Borlongan. "It’s a synergistic effect." He’s now following ...

Edible coatings will be the packaging of the future

...ied out with WPI coatings. Results showed that the protection capacity of the film depended on the amount of plastifier in the film, on its thickness and on the relative humidity of storage of the foodstuff. Thus, the most efficient WPI films were those of greater thickness, with less amount of plastifier and t...
