Abstract: An improved receptacle liner bag is formed of two layers of thin flexible stretchable plastic sheets which are sealed along the sides and bottom, but are unsealed along the top of the bag. The sheets are die-cut to form a framed opening which defines a band between the sides and the top of the bag. When the bag is placed in the receptacle, the band may be disposed around the outside of the sides of the receptacle and stretched over the base of the receptacle so as to provide a hold-down for the bag in the receptacle. The sheets may be perforated along a line below the framed opening. The line, when opened, forms an auxiliary band which can be stretched over and placed behind a hinge of a lid of the receptacle to secure the back of the liner bag in the receptacle.
