Find industrial grade Trash Can Liners that resist tears, punctures, and leaks. We carry high density trash bags for office buildings/restrooms, low density trash bags for sharper objects and rougher transport, and biohazard bags for safe disposal of your medical waste. Low Density Liners are made from high quality resins resistant to punctures and tears. High Density Can Liners are made from high density resins that are ideal for offices, restrooms, or any trash that does not include sharp edges.
1. Choose a bag size and bottom seal that matches the type of trash can being used
2. Choose your Trash Can Liner's Material
There are three types of plastic used in can liners: High-Density (HD), Linear Low-Density (LLD), and Reprocessed.
High-Density (HD) Plastic
High-Density plastic makes a “crinkly” noise when you move it – like a supermarket bag. HD plastic is also harder to start or puncture a hole in than Linear Low-Density (LLD). Once a hole is started in HD plastic, it will spread quickly or “zipper”. While High-Density can liners are thinner than Low-Density can liners, HD plastic can hold the same or greater weight. The thickness of this type of plastic is measured in Microns. This type of plastic can liner is best suited for cans without edges, paper, food, and smooth heavy objects. High-Density can liners offer substantial cost savings on a per-liner basis.
Linear Low-Density (LLD) Plastic
Linear Low-Density plastic can liners are quiet when moved, without a “crinkly” sound. It is easier to start or puncture a hole into than High-Density, but a hole with spread less quickly. The thickness of LLD plastic is measured in Millimeters. This plastic type is the most common. It has multiple uses and is recommended for sharper objects and tough transport conditions.
REPROCESSED PLASTIC
Repro plastic is reprocessed or made from recycled material. According to the EPA, 10-100% of the plastic is post-consumer recycled content. Reprocessed plastic can liners have a lower capacity for weight, but are also cheaper. Thicker reprocessed plastic can liners are needed to list the same amount of weight as a virgin resin bag (compared to the other types of plastics).
3. Pick your Can Liner's Seal Type
Harmony recommends a Star Seal bottom seal for can liners. This "bunched up" and star-shape appearance conforms well to large, round trash cans. Most importantly, star seals are not likely to leak. With these benefits, Star Seal Can Liners are the highest quality bottom seal type.
Gusset and Flat Seals are other types of can liners but do not offer the benefits of a star seal. Trash cans of unique sizes may benefit from other seal types, but for most applications, a star seal is ideal.
