Prime, high-quality resin delivers superior performance. Commercial-grade, linear low-density polyethylene provides excellent resistance to punctures, splitting & tearing. These characteristics make these liners an excellent choice for applications where additional strength & stretch are required, especially where waste with sharp or jagged edges is collected. Each liner also employs a star-seal bottom to maximize the bag's carrying capacity while virtually eliminating the potential for leaks. This more rugged, star-seal design allows it to conform more easily to the shape of your container while distributing the weight of refuse more evenly, making removing & replacing the liner during waste-collection tasks a much easier process.
