Customized Tab Lock Mailing Boxes

Tab-Lock Mailing Boxes are easy to assemble because they do not require tape, glue or staples. These boxes can usually be used for transport purposes; heavy objects can be placed in them without worrying about damage. They can also protect fragile and delicate products.

Choose the Best Material

When it comes to safe product delivery, corrugated material is the best choice; the corrugated stock is a member of the rigid family that adds more security to its content. We manufacture locking mailers using A, B, C, D and F Flute thick corrugated stock; it depends on how much weight customer requires. Let us know how much weight you would like to put inside and we will come up with right thickness of a corrugated material. We at Liquid Printer manufacture these boxes professionally. We create attractive designs, custom shapes and sizes. Our state-of-the-art printing facility carries out custom printing on them, which allows logo printing, key features and other product details.
