Zusammenfassung: | Sheet (12) of yieldable plastic foam, suitably supported by a laminating support film (82, 83, 84) or by providing an unfoamed skin on its surface. The sheet (12) makes an effective protective wrap for trees (10) and for metal coils (60). Young orange trees (10) can have trunks wrapped with many turns of very yieldable thick foam sheet (12) treated to prevent the passage of radiant energy as by a metallized polyethylene terephthalate support film. The sheet (12) provides very effective protection against freeze damage. Only one or two turns of thinner laminate protects grape arbors (40) against undesired budding in winter. Foam (81) backed with cross-tensilized polyethylene sheets (83, 84) provides excellent protective covering for metal coils (60). Sheet glass (110) and the like is wrapped in laminate of cushiony foam (141) backed by flexible open-face corrugated board or corrugated paper (142) or the like. |
