Are Plastic Boxes Good for Long-Term Storage

You must reconsider if you think storage is just about renting a storage unit and fitting your belongings. Storage boxes are vital in determining how smooth your storage journey will go. Choosing the right storage boxes is essential for organisational purposes and keeping all of your belongings safe and secure.

Storage boxes come in different sizes and materials, and each type has an intended function. While it’s tempting to throw everything in an enormous box and call it a day, it’s worth taking the time to make wise selections and choose the right boxes for the job.

You’re in the right place if you’re wondering about the pros and cons of using different storage boxes, like plastic containers and its alternative, cardboard boxes. Not only will we discuss the differences between them, but we will shed light on whether plastic boxes are suitable for long-term storage or not.


Pros Cons of Plastic Boxes for Storage


Pros of Plastic Boxes for Storage:

Storage in a plastic box is considered the ideal storage solution. It’s easily stackable and better protects your belongings from moisture, heat, and anything else that might cause damage. You don’t have to worry about packing tape either; plastic boxes are self-sealable.

However, they are more expensive than cardboard boxes, but because they’re relatively sturdier, you can use them for longer. If you opt for long-term storage, you may want to splurge on plastic bins.

You may be unable to break down the boxes to store them when they’re not in use, but they will give maximum protection to your belongings. Lastly, long-term storage in plastic is a great choice, especially if your items will be stored in a storage unit that isn’t climate controlled.

Cons of Plastic Boxes for Storage:

Plastic boxes have many advantages; however, plastic is generally more rigid to dissolve than cardboard. A disregarded plastic bin is much worse for the planet than a cardboard box. That’s why you should be mindful when choosing containers for storage. If you don’t plan to rent a storage unit for the long term, you’re better off getting cardboard boxes.

Let’s not forget, you’ll have to spend money on either choice, cardboard or plastic. So, which one is more affordable?
A cardboard box will cost significantly less than a plastic bin of the same size. However, if you intend to keep and use your plastic bin for an extended time, the cost can equal out. Remember, plastic containers rarely need replacement, but cardboard boxes need replacement more often.

On the other hand, cardboard is both recyclable and biodegradable, while plastic is only recyclable. Also, plastic is smoother than cardboard, so there is less friction between bins. It can lead to sliding if there is even the slightest balance issue. If stacked properly, plastic can’t be beaten – but when conditions are less than perfect, cardboard can often be more forgiving.

Pros Cons of Cardboard Boxes for Storage

Pros of Cardboard Boxes for Storage:

If you maintain your storage area, cardboard boxes can last much longer than intended. When storing, keep boxes on shelves so they are always off the ground. Don’t stack more than a few boxes high, and ensure the heavy items are on the bottom of the stack.

Another thing that will help keep your cardboard boxes in good condition for storage is a climate-controlled storage unit. It maintains the humidity and temperature level (be it hot or cold), so your cardboard boxes will not be affected by external conditions.

However, it leads to another dilemma. That is looking for top-notch climate-controlled storage units. But we are here for you! You can check out STORED storage units that are not only climate-controlled but affordable, well-lit, spacious, and thoroughly cleaned.

Cons of Cardboard Boxes for Storage:

Cardboard breaks down faster than plastic and is more susceptible to weather conditions like heat and humidity. They also take a shorter amount of time to age than plastic containers. Nevertheless, they are ideal for short-term storage and won’t cost an arm or leg.

Additionally, if you use cardboard boxes to store long-term items, they may not remain in perfect condition as you left them in. Remember, bugs are especially attracted to cardboard boxes and their contents. Hence, ensure your chosen storage facility has properly sanitised and fumigated storage units.

Also, adequately sealed concrete slabs and proper outdoor flooring is just as important when looking for a storage unit. If not sealed properly, it will seep moisture and get absorbed by the cardboard box and soil your items. If this happens, your items will become ruined, and mildew or mould will start growing in the box.

Regardless, if you choose to stack cardboard boxes in this situation, the bottom box walls will become compromised, and there is a chance of the stack falling. It’s always better to thoroughly research the quality of the cardboard boxes and the storage facility you choose than to regret it later.


Plastic bins are best in circumstances that require durability and resistance. Contrastingly, cardboard boxes are more readily available, cost-effective and best for temporary storage.

If you plan to move and unpack in a short period, cardboard boxes should suffice. But, plastic bins are the way to go if you plan on keeping items in storage for a long time.

In conclusion, plastic bins and cardboard boxes each have advantages and disadvantages. Your choice must depend on the situation and your specific needs. Sometimes choosing to save money is better than splurging. Occasionally, the opposite is better. Hopefully, our guide has helped determine your priorities for storage boxes and storage units.
