Abstract
A novel manufacturing technique for strengthening integrally molded handles on a membranous or thin-film article against tearing, by integrally molding the peripheries of the handles and adjacent rim regions of the article in a mold which provides a three-dimensional curvilinear pre-bias against the stress-pattern engendered by lifting of masses carried by the article.
