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!
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:
- Will sharp objects be disposed of in these liners?
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)
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!
