Corrugated Mailers

1. Measure the Product Measure length, width, and depth and include room for any wrapping, inserts, or protective material.

2. Match the Shape Choose literature, garment, side-loading, tuck-top, or another format that fits the product profile.

3. Check the Closure Closure methods vary by style. Review the individual product instead of assuming every mailer is tape-free.

4. Choose the Finish Kraft and white options are available across the category; availability varies by mailer family and size.

Corrugated mailers bridge the gap between a conventional shipping box and a flexible envelope. Their compact formats are useful when a product needs corrugated structure but does not require the depth or configuration of a standard RSC carton.

The category includes multiple designs because loading method matters. Literature and garment products may benefit from broad, shallow formats, while long or awkward items may be easier to pack through a side-loading opening. Tuck and fold designs provide additional options for general merchandise and fulfillment. Choose the mailer based on the full packaging system. Product dimensions, fragility, interior protection, closure, labeling, shipping method, and customer presentation should all be considered before selecting a style. Corrugated construction provides a rigid outer package for products that need more structure than a flexible envelope. Tuck, fold, outside-tuck, and side-loading configurations support different packing workflows. Mailer formats can provide a closer product fit than a larger general-purpose shipping carton. Many corrugated mailers are supplied flat and assembled when needed, conserving storage space before use.
