Commercial can liners are made of high-quality, virgin HDPE to consistently deliver a higher-than-average tensile strength, an excellent dart-impact rating as well as a reliable barrier against both odor and moisture penetration. So strong that they could be up to eight times stronger than the resin itself, their star-sealed bottoms help ensure weight remains evenly distributed. Preprinted with E-Z liner-identification labeling, their innovative clamshell box helps eliminate the possibility of confusion, especially where several sizes and\/or types of liners may be employed. For applications where there are no sharp edges, it's difficult to beat commercial-grade HDPE can liners.
