How to choose the best metal enclosure box: Important features to consider

Materials: Polyethylene vs. polypropylene – Low-density polyethylene (stamped on the bottom as LDPE, recycling group number four) is more flexible than stiff, cheap polypropylene (recycling group five), so it won’t crack as easily if you drop a loaded bin on the garage floor. It also won’t become brittle at freezing temperatures the way polypropylene does.

Each material has some advantages. Polypropylene can be made see-through, and it’s much more heat resistant — all the way up to boiling temperatures. LDPE is always tougher, but it gets very soft at temperatures above 110 degrees Fahrenheit and melts in boiling water. Our testers have seen far more polypropylene bins fail in long-term storage, especially in cold climates, but in a baking-hot attic, you’d want to be very careful about how much weight is stacked on an LDPE bin.

Latching lids – A flip-up latch will hold your bin closed even if you over-stuff it, which is handy for things like bulky sweaters and puffy blankets. If you put too much strain on latches, though, they’re prone to pop out of the mounting holes. Those holes also mean an entry point for moisture and insects.

A waterproof seal – If you just need a bin to shed rain, almost any will do: with one exception, the lids we tested to cover the edge of the bin, which means water will roll off without getting inside. A totally sealed lid (like our top pick) will also keep out humidity, though damp items can mildew quickly if you’re not careful about what you put in the bin.

Stackable designs – Nearly any bin can stand on top of another, but some designs are able to neatly mix and match small and large bins while creating a topple-resistant tower.

Single-size lids – If you’re building a collection of storage containers to fully organize your life, it can be handy to have bins with same-size openings. This usually means you can stack and nest different sizes as well as share lids between them. Usually, there will be at least two sizes in a series of containers with a common lid and footprint size, with the difference in volume made up by height.

What to Look for in a Plastic Storage Bin


“Pre-sort items you want to organize into categories for containment,” says Marci McAvoy, professional organizer and founder of Marci McAvoy Home Organization. After pre-sorting, consider the storage bin’s capacity. Measure what you need to store and the space where it will live.

“There’s nothing worse than buying a bunch of bins and getting home and realizing that your space is too narrow for the bin you chose, or maybe you didn’t realize that your shelves couldn’t be adjusted for height,” says McAvoy.

Plastic storage tubs list the capacity in quarts or gallons, and some may also include the weight limit. If you’re shopping online, you can get a sense of what a bin can hold by looking at both product photos and images posted by shoppers, which are often the most helpful.

Material and Design

Rigid plastic materials are less likely to buckle when filled with extremely heavy items. These are sometimes labeled as high-density bins. “A bin like this tends to be more expensive because it is really durable, keeps dust and critters out, and is airtight,” says McAvoy.

If you’re storing bins vertically, look for a stackable style (these usually have recessed lids), since this will help the bins stay stable and maximize your storage space from top to bottom. Note that some storage bins are narrower at the bottom and wider on top, so they can nest when they’re empty. This is a helpful feature, but if you are lining these up on shelves horizontally, you may have wasted space between them.

Lid Closure Type

Storage bin lids can be attached or removable. The attached lids might be on a single set of hinges, or they may split down the middle and interlock. When the lid is integrated into the design, you’re less likely to lose track of it, but McAvoy warns that sometimes these can break, rendering the entire bin unusable.

McAvoy prefers removable lids with side snaps and latches. If you live with small children, you might need to opt for more secure closures. If you love color-coding, consider lids that come in different colors. Others might opt for clear lids so they can easily see the contents.


  • When is the best time to buy plastic storage bins?

    Plastic bins often go on sale in January or February, when retailers try to capitalize on customers’ resolutions to get organized. Containers in colors like red and green maybe even more deeply discounted at this time.

  • How should you label plastic storage bins?

    There are almost as many labeling options as there are plastic containers. If you want flexibility, stick to erasable options such as removable chalkboard or whiteboard labels, and use either chalk paint or dry-erase markers. Label bin clips work well on the handles of open bins, and can also be used with dry-erase markers or Sharpies. Some people opt to simply write directly on clear bins, or buy pre-printed stickers. If you want your label to be permanent, use a marker like a Sharpie or an acrylic paint pen.

  • How can you hide plastic storage bins in your home?

    If you’re looking to hide storage bins in your home, one option is to buy larger, more attractive containers made from materials like wood or rattan, and fit the plastic boxes inside. This works best for items you don’t need frequently. You could also use fabric, washi tape, drawer liner paper, spray paint, and stencils to decorate the exterior of plastic storage bins. If you really don’t want to see them, opt for under-bed storage containers.

  • Can you recycle plastic storage bins?

    Check the number on the container as well as your area’s recycling rules. Many storage containers are made of polypropylene (labeled 5 or PP), and although this can be recycled, not all localities currently do this curbside, but some may accept them at transfer stations. You may be able to recycle polypropylene storage bins through a recycling company like TerraCycle. Try searching “specialty recycling company” and then the name of your town and state. Acrylic can be difficult to recycle, but some specialized facilities may accept it1. Products containing BPA cannot be recycled.2

    If you can’t easily recycle your old bins, try posting them on a local swap group such as Buy Nothing or Freecycle, or using them for other home projects, such as building a terrarium or mini greenhouse. If they’re clean and in good condition, you can also donate them.
