Trash Can Liner

Buying Guide

Header Image

While choosing a trash can liner may seem as simple as finding one that will fit your waste can, there are a handful of terms you must familiarize yourself with and consider to ensure that your selection will provide the best results at the best price!

Gauge

Gauge is a term used to describe the thickness of a liner that is typically stated in either microns (high density) or mils (low density).

  • Micron: A measurement based on one hundred thousandths of an inch (.00001). High density trash can liners range from 6 to 24 microns.
  • Mil: A measurement based on one thousandth of an inch (.001). Low density trash can liners range from .30 to 2.5 mils.
Expert Tip
Comparing the thickness of a high density bag to that of a low density bag is a matter of basic mathematics, when considering that 1 mil = 25.4 microns

Resin

Hercules & Li'l Herc Trash Bags

Resin is the basic raw material used in manufacturing trash can liners. The two basic types of resins utilized in trash can liner manufacturing are high density and low density.

  • High Density Can Liners: Great for paper and lightweight trash; tears easier if punctured.
    • Excellent choice for offices or bathrooms, as long as no sharp or irregularly-shaped objects are being discarded.
    • Lighter construction means lower freight, storage, and warehousing costs.
    • Superior vapor and moisture protection; USDA and FDA approved for food use to help contain unpleasant odors.
    • Temperature-resistant from -40 to 212 degrees Fahrenheit.
  • Low Density Can Liners: Great for heavy, wet trash; provide exceptional resistance against puncturing and tearing.
    • Excellent choice for kitchens, yard waste and other trash with sharp, jagged edges.
    • Superior stretch properties make for a great multi-purpose can liner.
      • Hercules Contractor Trash Bags
      • Our Hercules industrial can liners are extra heavy low density can liners, offering the same benefits as low density liners with even greater thickness for heavy duty kitchen, yard waste and construction use!

Expert Tip
We offer a select number of linear low density liners which provide the same superior stretch benefits as standard low density liners. But because of differences in the manufacturing process, linear low density is able to achieve greater strength at a thinner gauge.

Seal

Seal is a term used to describe the bottom of a liner. Seals come in three types: star, flat, and gusset.

  • Star Seal: The most common seal in the industry, star seals are manufactured by folding the bottom of the trash can liner over several times and then sealing it. This virtually eliminates leaks and allows the liner to conform to the shape of the waste receptacle and distribute the refuse evenly around the bag.

  • Flat Seal: Manufactured by simply sealing the bottom edge so that no length of the liner is sacrificed, flat seals provide a generally leak-proof product. They do not, however, conform well to the waste receptacle and can be difficult to handle.

  • Gusset Seal: Manufactured with both sides of the bottom edge tucked in to form gussets, gusset seals are reinforced at the indented outer edges with four layers of film, while the middle of the bag is sealed with two layers. This causes a tendency to leak with wet trash.

So How Do I Choose The Right Can Liner?

Choosing the right can liner for your specific needs is as simple as asking yourself three questions:

  1. Will sharp objects or heavy, wet trash be disposed of in these liners?
  2. What size liner do I need?

    Trash bags are measured by their length and width when laid flat--the first measurement in the title of our cans is the width, and the second is the length. To determine what size bag is needed for your particular waste receptacle:

    • Bag Length = Height of your can plus 3" for overhang
    • Bag Width = Circumference of your can divided by 2
      • Square Container Circumference = Sum of all four sides added together
      • Round Container Circumference = Diameter multiplied by 3.14 (or pi, if you channel your middle school math teacher)
  3. How much weight will these liners need to hold?

    • Simply estimate the average weight of a full trash can liner in your application, match it to the max load capacity listed in the description for each liner that meets your needs from the previous two questions, and you've got the bag that's right for you!
    Expert Tip
    We also have specialty liners for more unique needs and applications! These include translucent recycling bags that make it easy to see if non-recyclable materials are mixed in, medical waste bags with the universal biohazard symbol for easy identification, and compostable bags that are an excellent choice as an eco-friendly alternative to traditional bags and perfect for disposing of yardwaste and other compostable materials.
