Choosing the Right Trash Bag Can Liner

It is very important, with any trash, that it is properly disposed of. This is particularly relevant with hospitals that are constantly getting rid of hazardous waste. They have to get rid of needles and sharp objects all the time. Restaurants and hotel kitchens also have to dispose of old food and liquids. In either case they need the right type of can liner to prevent leaks and tears. If a tear was found in a hospital can liner this puts individuals at risk of infection. How do you know which type of can liner is the best for your application?

High-Density Can Liners:

Ultimately, there are two types of can liners for you to choose from. First there are high-density can liners.

This type of can liner is generally used in places that are not required to hold any heavy material. It is perfect for an office and bathroom space. Feminine hygiene convenience disposable bags, for example, are made to create a more hygienic workspace by giving women the opportunity to properly dispose of their feminine products

Low-Density Can Liners:

The second type of can liners are low-density can liners.

These types of can liners are designed to carry much heavier material than a high-density liner would be able to hold. It is commonly used in hospitals and restaurants because of it being puncture and tear resistant.


A seal is how the bottom of the trash can liner is folded and sealed. Depending on the application, a can liner with the right type of seal can greatly benefit you.

3 Types of Seals:

Good Can Liner:

Gusset Seal – both sides of the bottom edges are tucked in to create gussets. The seals are then reinforced at outer edges with four layers of film with the middle being reinforced with two layers.

This type of can liner does tend to leak and should be used for holding flexible dry material. Gusset seal is perfect for the office or workplace that disposes of a lot of paper. It can also be used by hotels for collecting linens and laundry.

Better Can Liner:

Flat Seal – there is no folding and it’s sealed so that the length of the can liner remains long. It does not fit well in a waste receptacle which can make it difficult to use is some situations, but it is leak proof.

Because a flat seal is leak proof this type of can liner is perfect for those who have to dispose of liquids and foods such as restaurants and hotel kitchens.

Best Can Liner:

Star or ‘X’ Seal– this is the most common type that is folded several times and then sealed. It is able to distribute the weight of the waste evenly and prevents leaks.

This type of can liner is perfect for those who have to dispose of sharp objects, broken glass, or mass waste such as hospitals, restaurants, hotels, warehouses, shopping malls, schools, and large commercial spaces.

Other Aspects to Consider:

When you are trying to figure out the length of the can liner that you should get remember the following:

  • Liners should be 3-4 inches taller than the wastebasket
  • Bag width = ½ the outer circumference of the container
  • Bag length = height of the container plus ½ diameter of the container bottom

To find out the bag’s length, width, and carrying capacity, just look on the product’s box. Most trash bags have the dimensions located on the front of the box towards the bottom.
