Efficiency of various overwraps and seal tightness in excluding insects from dried-fruit cartons
Environmental Entomology 12 (5), 1310-1311
Abstract: Fourteen types of overwraps on raisin or prune cartons were tested for insect resistance against nine species of stored-product insects. They were classified into three categories of seal tightness. The most insect-resistant overwrap on a raisin carton was a 0.9-mil, heat seal-coated, biaxially oriented polypropylene film, and the most resistant prune carton overwrap was a 2.5-mil, polyethylene-coated foil overwrap. Raisin cartons of all types of overwraps classified in the tight-seal category averaged 18.7% infested, whereas prune overwraps in the same category averaged 8.2%. The averages in the tight-seal category were lower than infestation rates of any type of film individually; thus, a tightly sealed overwrap was more important than the type of overwrap used.
