The Staggering Use of Plastic Bags Worldwide
Plastic bags are ubiquitous in modern society. We use them for everything from groceries to storage to waste disposal. However, most people don't realize just how many plastic bags are used globally each year. The numbers are staggering.
- According to the Earth Policy Institute, approximately 1 trillion plastic bags are used worldwide each year.
- On average, the world consumes 300 million tons of plastic annually, much of which is single-use items like plastic bags.
- Every year, Americans throw away 100 billion plastic bags after they've been used just once.
To put this in perspective, that's nearly one plastic bag per person per day. And that's just in the United States. Scale that worldwide and the number is mind-boggling.
Plastic Bag Usage in the US
Here's a quick look at how reliant the US is on plastic bags:
- The average American family takes home almost 1,500 plastic bags per year.
- Only 1% of plastic bags are returned for recycling.
- Billions of pounds of plastic bags end up as litter each year.
Part of the reason plastic bag usage is so high is because they're free and readily available at most retailers. Many shoppers don't think twice before grabbing a handful of bags, even if they may not need them all.
The Impact of Plastic Bag Waste
All of this plastic bag waste is taking a tremendous toll on the environment:
- Plastic bags don't biodegrade. Instead, they photodegrade, breaking down into tiny toxic bits that contaminate soil and waterways.
- Plastic bag litter clogs storm drains, leading to flooding and breeding grounds for mosquitoes.
- Bags get swept out to sea by the wind or through storm drains. This plastic pollution Chokes marine wildlife and litters beaches.
Clearly, the prolific use of plastic bags is not sustainable. Major change is needed to reduce our reliance on single-use plastics that have such a disastrous impact.
As we'll explore later in this article, there are steps both individuals and governments can take to cut down on plastic bag pollution. But first, it's important to understand just how pervasive plastic bags are worldwide.

The Many Types of Plastic Bags and Their Uses
When most people think of plastic bags, the standard grocery store or shopping bag comes to mind. However, plastic bags actually come in a variety of forms, sizes, and thicknesses for different purposes. Here are some of the main types of plastic bags and their common uses:
Poly Bags
Poly bags, also known as polyethylene bags, are made from polyethylene plastic. They are thin, lightweight bags that are moisture-resistant and transparent. Some common uses of poly bags include:
- Food storage bags
- Zipper storage bags
- Clothing bags
- Shipping envelopes and mailers
- Glove bags for cleanroom environments
Plastic Shopping Bags
These are the most ubiquitous plastic bags that shoppers are given from grocery stores, retailers, restaurants, etc. They are made from low-density polyethylene (LDPE) and come in various sizes. Most have handles for carrying purchases.
Garbage Bags
Garbage bags are made from LDPE or linear low-density polyethylene (LLDPE). They are intended to hold waste without leaking and are manufactured in many sizes from grocery bags to contractor bags.
Freezer Bags
Freezer bags are constructed from polyethylene plasrics that are designed to prevent freezer burn. Many have zipper seals or slider closures. They allow for storage of frozen foods.
Vacuum Bags
Vacuum storage bags are made of multi-layer polyethylene and are designed to have air sucked out of them before sealing. This helps preserve foods, compress items being stored, and prevent mildew.
Gusseted Bags
Gusseted bags have pleated sides that allow the bag to expand. This style is useful for holding large or bulky items. Gusseted bags are popular for pet food, bird seed, charcoal bags, and more.
Deli Bags
Deli bags are food safe plastic bags used by restaurants, cafeterias, and delis to package takeout food. They often have fold over closures or zipper seals.
As you can see, plastic bags come in all different forms and have diverse uses. The key is choosing the right plastic bag for your particular needs. Being aware of the many options available can help you find the perfect bags.
How to Select the Best Plastic Bags for Your Needs
Plastic bags come in so many varieties today that it can be tricky to figure out exactly what type of bag suits your purpose. However, by considering a few key factors like size, thickness, closures, and intended use, you can zero in on the perfect plastic bag for any situation.
Consider the Size
One of the first things to think about is what size plastic bag you need. Common sizes include:
- Small - sandwich bags, 1-2 lb storage bags
- Medium - gallon storage bags, grocery bags
- Large - contractor bags, bags for bedding
- Bulk - bags for pet food, lawn clippings, charcoal
Match the size to the item(s) the bag will contain. Allow a little extra room so the bag is not stretched to the point of tearing.
Determine the Right Thickness
Plastic bag thickness is measured in microns. Some general guidelines are:
- 20-35 microns - deli bags, produce bags
- 35-50 microns - trash can liners, grocery bags
- 50-100 microns - shipping envelopes, storage bags
- 100+ microns - heavy duty contractor bags
Choose a thickness suited to the weight and sharpness of the contents. Heavier items require thicker plastic to avoid rips.
Consider Closures
Many plastic bags seal with simple folded over tops while others have zippers, press seals, drawstring closures or adhesive strips. Decide which type offers the best containment and ease of use for your purposes.
Understand the Intended Use
Finally, match the bag to its intended function whether that's storage, organization, freezing, cooking, retail use, shipping, waste disposal or any number of possibilities. The right bag for the task makes all the difference.
By weighing these key criteria, you're sure to end up with the ideal plastic bags. And you'll avoid waste and frustration from flimsy or ill-fitting bags breaking and failing to do the job.

Effective Methods for Labeling Your Plastic Bags
Labeling plastic bags serves many useful purposes whether for branding, identifying contents, warning labels, directions or sealing. There are a few key techniques for labeling your plastic bags cleanly and clearly:
Adhesive Labels
Self-adhesive labels can be quickly adhered to plastic bags for a polished look. Options include:
- Pre-printed labels - Professionally printed with your branding, graphics, contents, etc.
- Blank labels - Purchase blank label sheets and print your own customized labels.
- Shipping labels - Specifically designed for shipping bags and envelopes.
Make sure to use labels appropriate for plastic surfaces and bag flexibility so they adhere properly when the bag bends.
Vinyl and Fabric Markers
For hand labeling plastic bags, vinyl and other permanent markers specially formulated for non-porous surfaces work well. Write neatly and allow ink to fully dry.
Paint Pens and Grease Pencils
Oil-based paint pens and grease pencils provide vivid color on plastic. Use for labeling, directing (e.g. "this side up"), or adding graphics and logos.
Static Cling Decorations
Static cling vinyl in pre-cut shapes can temporarily decorate bags. Use for holidays, events, branding, or sealing closures.
Tag Fasteners and Ties
Plastic tag fasteners and twist ties allow you to attach paper labels or tags with warnings, contents, cooking instructions or preparation directions for food storage or retail bags.
Choose the labeling method that achieves the look, durability, and functionality needed for your specific plastic bags and contents. Consistent labeling brings an organized, professional appearance.
Proper Storage and Care for Plastic Bags
Like any item, proper storage and care is key to keeping plastic bags in good condition so they last longer. Follow these tips to prolong the usefulness of your plastic bags:
Avoid Heat Exposure
Heat can warp and melt plastic bags. Keep bags away from direct sunlight, car interiors on hot days, and anywhere with extreme heat such as on top of appliances.
Protect from Moisture
Moisture causes plastic to degrade faster. Store bags in a dry area of your home away from sources of dampness like basements or bathrooms.
Prevent Punctures
Sharp objects can puncture and tear plastic. Ensure bags are not stored near tools, kitchen utensils, etc. that could poke holes.
Use Proper Bags for Freezer Storage
Only special freezer bags should be used to store items in the freezer. Regular plastic bags can become brittle and crack when frozen.
No Chemical Exposure
Chemical agents like cleaners, solvents, oils, etc. can deteriorate plastic bags. Keep away from any chemical storage areas.
Fold and Stack with Care
To conserve space, fold bags neatly and stack according to size to keep organized. Do not overstuff or forcefully cram bags which strains the material.
Inspect for Damage
Occasionally inspect bags for any cracks, holes or tears that could compromise effectiveness. Damaged bags should be recycled.
Clean as Needed
Wipe plastic bags down with a damp cloth to remove dust and debris. Allow to fully air dry before storing or reusing.
By keeping these simple plastic bag storage and care tips in mind, your supply of bags will stay in optimum condition and remain useful for many years to come.
