Bsc Preferred M12121K Corrugated Kraft Mailer 50 Pack

Product Description

The BSC PREFERRED M12121K is a one-piece corrugated kraft mailer designed for economical product shipping and fulfillment operations. Built to 200/ECT-32-B kraft corrugated construction, it delivers reliable crush resistance while keeping material weight low to help reduce mailing costs. The mailer features scores at multiple depths, allowing the user to fold the sides to the exact depth needed for the product being shipped. Seal with standard packaging tape to close. Sold in a pack of 50. This style is well suited for mail-order distribution centers, shipping departments, and fulfillment operations that need a flexible, size-adaptive mailer without switching between multiple box sizes.

These mailers are appropriate for lightweight retail goods, flat or shallow products, and similar items that benefit from a snug, adjustable fit. The single-piece design eliminates the need for separate lids or inserts, streamlining pack-out on a fulfillment line. The kraft corrugated material is standard for parcel and ground shipping environments and is accepted by major carriers. Operations handling varied SKU sizes in one workflow will find the multi-score design particularly efficient.
