When selecting how strong a shipping box needs to be, it's best to use these guidelines below to insure you choose the correct box.
- If your product weighs less than 30 lbs and you are stacking boxes on a pallet, go with a 32 ect box. 32 ect (edge crush test) means the box can withstand 32 pounds per inch of pressure before the edges of the box will crush
- If your product weighs 30-40 pounds and you are stacking at least 5 boxes high on a pallet, go with a 200# bursting strength box. 200 lb. just means the box can withstand 200 pound of pressure per inch before the box bursts. This box is the next strength up from a 32 ect box.
- If your product weighs 30-40 pounds and you are shipping out individual boxes via ups or fed-ex, stick with a 200 lb box.
- If your product weighs more than 40 pounds and you are stacking 5 high or more, go with a 275 lb bursting strength box, so that the bottom layer of boxes on the pallet dont crush, bust, or burst.
- Now if your product weighs 50-60 pounds or more and you are stacking 5 or 6 high on a pallet, go with a 200 lb double wall box for additional strength to withstand the weight, pressure and structure during stacking and shipping.
- If your box weighs 70 to 80 lbs, go with a 275# Double wall box.
- Certain boxes will need to be 350# Double wall when the contents inside the box weight more than 80 pounds and if you are stacking high on a pallet.
