How Do You Know What Type of Can Liner to Choose?

High Density Bag

High Density Bags are great for paper and non-rough objects under moderate transport conditions. Example: These liners are very strong and handle higher load capacities than LLD liners, but are less resistant to tears once punctured. Suggested applications: • Cans w/out rough edges • Paper • Paper plates/cups • Food • Dirt • Grass • Rags/Cloth items • Smooth heavy object • Great for office waste baskets

Approximate Gauge (thickness) • Light 6 – 9 Mic • Medium 10 – 12 Mic • Heavy 13 – 14 Mic • Extra Heavy 15 – 17 Mic


Low Density Bag

Linear Low Density Bag is recommended for rough objects under tough transport conditions. Example: These liners are very strong and are more resistant to tearing, but handle lower load capacities than Hi-D liners. Suggested Low Density applications: • Sticks & rough yard trimmings • Metal w/ sharp edges • Nails & Bolts • Objects w/ rough corners or protrusions • Small rocks • Plastic eating utensils • Abusive transport conditions • Food w/ rough edges (ex: crab legs) • Glass Bottles


Trash can liners are usually an afterthought at most places of business. A business either purchases the same can liner they have forever because the item number to reorder is easily accessible or because they don’t know the right questions to ask their vendor to ensure they have the proper can liner.  Did your vendor talk you into a great sale on a can liner that doesn’t fit your application?


 What are the proper questions to ask or explore for your needs?

What type of waste is being collected?

Have your can liners ever ripped? There is a chance you had a high density liner in a receptacle that sharp objects were being placed in that could have caused the tearing.  This indicates the improper usage of a high density liner in an application where liner low density bags are the proper solution. Side note: If you are placing sharp objects into a low density bag and it is still ripping, changing to a heavier or thicker bag won’t prevent puncturing.


In use cases where light waste like paper, cups and materials typical of an office environment are present a high density liner would be the proper choice. Using a linear low density liner or a liner that is too thick or heavy for the waste inside would raise costs unnecessarily.


How long before the container is emptied?

In many cases containers are emptied rather frequently resulting in a light total weight of waste in the liner at the time it’s emptied. This causes companies to spend too much money on liners with a mil thickness or micron that is too heavy duty for their needs.


What size is the receptacle?

Many times people purchase liners that are too large for the receptacle. Why do they do this? Often times it’s easier to buy the next size larger liner instead of sourcing the proper size. While easier to empty it causes too much free space in the liner, which raises the cost.


Another factor to consider is the sustainability of the liners you purchase. Biodegradable can liners are available that break down in a landfill much quicker than traditional plastic liners that take years to break down, if they do at all.
