You can protect your deliveries with 17 x 20 large shipping boxes. Sized for big items, these cartons feature corrugated Kraft construction to withstand the rigors of mailing. Consider choosing from standard duty boxes for all-purpose use or you can use double-walled cartons to ship fragile and heavy objects. You can buy a single box for a special item or you can stock up with a bulk pack. For an eco-friendly approach, consider selecting boxes made from recycled content, which helps reduce paper waste.
Shipping and moving boxes may not always be interchangeable. It's usually better to mail items in shipping cartons to withstand the transit, rather than those made for moving or storage. Tough kraft construction can help the box resist rips and tears. Top flaps fold over to seal easily with some moving boxes featuring cut-out handles making them easy to carry.
This size shipping box can provide ample room to pack large or bulky items. Consider finding 17 x 20 boxes in different heights for a secure fit preventing shifting while in transit. Tall boxes can accommodate large, yet slender objects, such as a pendant light or a water cooler. Smaller boxes are generally good for items such as printers or glassware.
You can protect medium-weight shipments with standard duty or heavy duty boxes. Standard duty boxes feature single-wall construction. They typically have a Bursting Test strength of 200 pounds and an Edge Crush Test rating of 32, enough to hold medium-weight, non-fragile items, such as paperback books. The Bursting Test measures how much force the sides of the box can withstand before they will rip, providing a guide as to how your package would fare if dropped. The Edge Crush Test, or ECT, rates the load-bearing strength, which denotes the likelihood of your package getting crushed under other boxes or heavier items. Heavy duty boxes usually feature single-wall construction yet they can handle a bit more weight, with a 275-pound Bursting Test strength and a rating of 44-ETC. These are a good choice for moderately heavy shipments that need extra protection but aren't extremely delicate. One such example would be a medium-size kitchen appliance.
Double-wall or triple-wall boxes are ideal for shipping both heavy and fragile items. These shipping boxes are usually made from heavy duty corrugated Kraft material. Triple-walled boxes can be reliable, with a 1,100-pound Bursting Test strength and a rating of ECT-90, on average, so they are strong enough to ship fragile artwork or items that weigh more than 100 pounds. Keep in mind that even the most durable box may not be able to prevent damage caused by shifting so be sure to pack your deliveries with plenty of protective material.
