Abstract
An improved laundry bag is disclosed which includes a combined bag closure and support band or flap having a specially configured lower edge which intersects the side seams of the bag at an acute angle. This angle of intersection distributes stresses developed in use in the closure and support band or flap so that the tendency to tear at the side seams or elsewhere is reduced substantially. The bag preferably is made from bias-cut material, which minimizes puckering of seams and adds extra stretchiness to the product. The bag also includes an improved form of handle pocket at its lower end. A method of manufacture which minimizes material wastage is also disclosed.
