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 25 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 -

  • Quality Assurance – These mailers add sturdiness to all the shipments. This ensures product safety and better delivery.
  • Cost-effectiveness – Due to their robust structure, they minimize the risks of packages getting damaged while in transit. Their reusability also makes them an economical choice.
  • Customizable – You can customize these 18 x 12 x 3" boxes with brand names and logos to promote your company. You can design online and the results are printed in full-color CMYK.
