A Classic Packaging Choice

These mailer boxes are made from 200# B Flute: 1/8" corrugated board which means that they can withstand a weight of 200 lbs. per square inch. They are delivered as 50 pieces per bundle.

Made in the USA, they are manufactured by using superior quality products and machinery to avoid any compromise. Some advantages of using UCanPack’s mailer boxes are:
