Can Liner Selection Guide
The right bag can make all the difference.


Go to Can Liners and BagsIdeal Size + Ideal Strength = Savings
 
Selecting a plastic can liner that is both the appropriate size for your trash receptacle and also manufactured to the strength rating required for your application will help you optimize your commercial can liner budget.
 
Buying only what you need to get the job done correctly is the key to savings, and the savings is usually more money than you think.

 Step 1:  Start Simple, Determine the Ideal Size... 

The larger the size of the bag, the more it will cost. When you buy a can liner that is sized too big for your receptacle you are paying for the excess overhang, basically the extra plastic resin. 
 
The cost difference does not seem like much when viewed on a purchase by purchase basis, however when viewed on an annual usage basis, trimming these excess costs can mean big savings to your budget. 
 
Use the tips below and take some measurements to find the liner that is best for you:

Can Liner MeasurementsCalculating the Ideal Width                                                                                


1. Measure the circumference of your receptacle.
        Square receptacle = sum of all four sides
        Round receptacle = diameter multiplied by 3.14

2. Divide this value in half, this is the Ideal Width for your can liner.

Calculating the Ideal Length                                                                               

1. Measure the height of your receptacle.
2. Measure the the diameter and divide this value in half.
        Rectangle receptacle, diameter is the diagonal
        Round receptacle, diameter is the distance across the middle

3. Add the height + half the diameter + 4 inches overhang = Ideal Length.

 Step 2:    Apply Your Knowledge, Determine the Ideal Strength... 

How you intend to handle or move the can liner and the type of trash it will need to carry are the major factors for determining the strength required. Typically, the stronger or more robust the liner, the more it will cost.

When you buy a can liner that is stronger than required,  you are paying for the enhanced plastic that is not really need to get the job done.  When you buy a can liner that is not strong enough, the costs of failure, doubling up, and labor time will be higher than they should be.

Determine the best plastic type based on the typical trash it will hold. Linear low density plastic bags provide superior tear resistance and is best for sharp objects or in environments with higher risk of tears either from the surrounding environment or through transportation to disposal unit.  High Density plastic bags provide greater load capacity and moisture resistance and is great for waste that is heavy or wet.

Determine the weight it needs to carry by estimating or you can actually weigh a full trash can liner for each differing application within your facility.  You can match this to the max load capacity listed for each type of liner.  Liners are most commonly categorized by a strength grade rating, max load or wet load, and a gauge in either microns or mils.
 
The following some basic guidelines to help you make the best choice:
 
 Strength Rating      
 Max Load  

 Application                                                                                      
Light 5 lbs.
Dry paper, cups, and light waste.
Medium 15 lbs.
Packaging waste, wet paper and mixed trash.
Heavy 15-30 lbs.
Light wood, metal scraps and wet cardboard.
Extra Heavy 30-45 lbs.
Consistently heavy trash, wet or sharp.
XX Heavy 45 lbs.
Heaviest cleanup jobs, warehouses, cafeterias, or facilities grounds.
