ABSTRACT:
Sheet of yieldable plastic foam, suitably supported by laminating to support film, or by providing an unfoamed skin on its surface makes an effective protective wrap for trees and for metal coils. Young orange trees can have trunks wrapped with many turns of very yieldable thick foam sheet treated to prevent the passage of radiant energy as by a metallized polyethylene terephthalate support film, provides very effective protection against freeze damage. Only one or two turns of thinner laminate protects grape arbors against undesired budding in winter. Foam backed with cross-tensilized polyethylene sheets provides excellent protective covering for metal coils.
