How to Properly Store Cardboard Boxes

Sandra Birne • July 2, 2024

Cardboard boxes come in different shapes and sizes and are often used for moving or self storage because they’re economical and easy to find. However, storing these boxes long-term requires some know-how. Here’s a guide on when to use cardboard boxes and how to store them properly.

The Basics of Storing Cardboard Boxes

Cardboard boxes are great for moving, but they aren’t the best for long-term storage. After moving, it’s common to leave items in cardboard boxes and put them in storage areas like the garage, attic, basement, or shed. However, unpacking your items and storing them properly is often a better choice.

Why Cardboard Boxes Aren’t Ideal for Long-Term Storage

  • Quick Deterioration: Cardboard breaks down faster than plastic and is affected by heat and humidity.
  • Pest Attraction: Bugs are drawn to cardboard and can damage both the boxes and their contents.
  • Moisture Damage: If stored on a concrete floor or in a damp area, cardboard can absorb moisture, leading to mold and mildew, and compromising the integrity of the boxes.

How to Store Cardboard Boxes Correctly

Maintain Your Storage Area

  • Keep boxes off the ground by using shelves.
  • Don’t stack boxes too high, and place heavier items at the bottom.

Use Self Storage

  • If possible, choose a storage unit. This helps regulate temperature and humidity, preserving your cardboard boxes longer.

Opt for Indoor Storage

Consider storing boxes in areas with wooden floors, like an attic or indoor self-storage unit , to prevent moisture absorption from the ground.

When to Use Plastic Totes Instead

For better long-term storage, plastic totes are often a safer bet. They resist moisture, don’t break down as quickly, and protect against insects. Here’s why plastic might be a better choice:

  • Durability: Plastic totes are sturdy and stackable.
  • Moisture Resistance: Sealed plastic boxes keep out moisture, protecting your items.
  • Insect Protection : Bugs are less likely to get into plastic containers.
  • Organization: Clear plastic totes allow you to see what’s inside, and colored lids can help you organize by theme (e.g., green for Christmas items, red for Valentine’s Day).

When deciding whether to use cardboard boxes or plastic totes for long-term storage, consider the environment of your storage area. For damp or pest-prone areas, plastic totes are the safer choice. If you need quality storage boxes, visit a U-Lock Mini Storage location for a variety of sizes. And if you need extra space, consider renting a storage unit at one of our U-Lock Mini Storage for reliable storage solutions.
