Best Practices For Selecting & Packing Corrugated Mailer Boxes

Brown Mailer Box - 8 x 4 x 3" - 50/Bundle (1)

Pick the Right-Sized Box – Compare and confirm the size dimensions of the box with your product to get the right fit, as it is the most important step in preventing destabilization during any movement, handling, and shipping. There can be product damage if the box size is too big or small. Choose a box size that is closest to your product size.

Use Correct Inserts and Cushioning – To enhance the safety of the packaged goods, especially if they are delicate and prone to breakage, you can add cushioning inside the box with bubble wrap, colorful crinkle paper, air pillows, or foams to withstand rough transportation or handling. If packing multiple items in a box, use customized inserts like fitments and partitions based on product size to prevent any shifting during transit.

Seal the Box – These mailers have a tuck top, therefore, tuck in the flaps meticulously. To add more safety against product displacement, use sealing tapes for the box.

Label – Add colored tags or instruction labels to the packaged shipments to provide precise handling or unboxing instructions and to make them easily recognizable in a sea of deliveries.
