Can Liner Information
Linear Low Density (LLD) – Multipurpose can liners recommended for sharper objects and tougher transport conditions. Greater tear resistance compared to HD liners. Offers food puncture resistance and load capacity.
High Density (HD) – Much thinner than LLD liners, yet can hold the same or greater weight. Good tear resistance. Better puncture resistance and load capacity when compared to LLD liners.
Understanding Gauge Thickness
Gauge is a term used to describe thickness. Film thickness is no longer the standard for judging bag strength. Advanced resins and additives have allowed manufacturers to produce thinner, lighter can liners that are stronger than thicker bags made from lesser quality materials. Linear Low Density Can Liners (LLD) are measured by mil thickness; High Density Can liners (HD) are measured by micron thickness.
Mil (one thousandth of an inch) – One mil equals .001”. Can liners range between .35 to 4.0 mils.
Micron – 25.4 microns equals .001”. 1,000 microns (M) is 1mm. Can liners rang between 5 to 24 microns.
Gauge Equivalents
Static load (lifting strength) is the best way to choose bag strength. Below are the approximate gauge equivalents for static load:
Strength Grade | Linear Low-Density Mil Gauge | High-Density Micron Gauge |
Light | .35 - .44 | 5-9 |
Medium | .45 - .57 | 10-12 |
Heavy | .58 - .69 | 13-14 |
Extra-Heavy | .70 - .89 | 15-17 |
XX-Heavy | .90 – 1.14 | ……… |
Super | 1.15 – 1.39 | ……… |
Super-Heavy | 1.40 & up | 18-24 |
Strength Grade Key
Light – For crumpled papers, cups, light waste, etc.
Medium – For packaging waste, wet paper, etc.
Heavy – For light wood, metal scraps, wet cardboard, etc.
Extra-Heavy – For heavy, sharp or wet trash
Super/Extra-Heavy – For heaviest cleanup jobs in warehouse, cafeteria or facility grounds
Bottom Seal Types
Star Seal – Designed without gussets, this is the most common type of seal. The star seal eliminates gaps along the seal, allowing the bag to conform more easily to the shape of the waste container. Sate seal liners more evenly distribute weight inside the bag, maximize carrying capacity and help eliminate leaks.
Gusset Seal – Designed with both sides tucked in to form gussets, this seal is found on flat-style bags. Gusset seal liners are sealed through four layers of film where indented and just two layers of film in the middle, creating a potentially weak bottom seal.
Flat Seal – Designed with a bottom seal to create a two-dimensional bag, much like a pillowcase. Flat seals are strong along the bottom, but may leak from the corners. Liners with a flat seal do not conform as well to the shape of most containers.
