Used Cardboard Moving Boxes are unsanitary and new boxes are expensive.
Not convinced, be aware of how box quality, size and loads will affect your move. Moving Boxes come in all shapes, strengths and sizes. The stronger the moving box, the greater the protection for its contents.
Professional movers use moving boxes that are at least 32 ECT (200 lb test) in strength. These ratings are standard from the box industry, and help insure that your household products will arrive safely. Weaker cardboard moving boxes will crush under load.
There are some retailers which sell much weaker cardboard boxes calling them moving boxes. Beware such boxes are designed for light-weight usage and should not be considered for moving.
All boxes have a certificate seal printed on the bottom flap by the manufacturer certifying the boxes strength. Industry standard are as mentioned above. Larger boxes like wardrobes or kitchen dish pack boxes should have a higher rating.
Just because a box is large, doesn't mean it can carry a lot of weight. Make sure to check box strength before you make a purchase to ensure that they are adequate for your needs.
New cardboard moving boxes are more expensive to purchase than renting IT'S YOUR MOVE crates and totes. Cardboard moving boxes have to be assembled, they get crushed and wet, and eventually fill up our landfills.
You should keep in mind that used cardboard boxes do get weak when reused. Cardboard boxes get ruined when they get wet. One of the biggest concerns is the sides of the box, where the seam is glued. Over time, this glue becomes unreliable. If you use used cardboard boxes, you should inspect them carefully before packing.
Sometimes in an effort to save money, people attempt to recycle produce boxes. Beware, produce boxes often become weakened from moisture, refrigeration and product spoilage during transportation. They at times house insects that can infect your new dwelling.
Boxes obtained from grocery or liquor stores are not always clean, and may not withstands the weight of the items you will be putting in them. Their odd sizes tend to make securing a load more difficult.
