Bsc Preferred MLR3K Kraft Corrugated Mailers 50 Pack

Product Description

The BSC PREFERRED MLR3K is a pack of 50 kraft corrugated mailers designed for shipping small, lightweight, and fragile items while minimizing postage costs. Manufactured from 200/ECT-32-B kraft corrugated material, these mailers fold to create double walls of protection on the front and sides. The self-locking design requires no tape, glue, or staples, making them fast to assemble during high-volume pack-out. Each pack contains 50 mailers and weighs 9.82 pounds. These are a practical choice for fulfillment operations, shipping departments, and warehouse staff who need a reliable, crush-resistant mailer without added closure materials.

The MLR3K mailers are suited for residential and commercial shipping applications where small, breakable, or light goods need protection in transit. Common use cases include e-commerce fulfillment, parts distribution, and internal supply chain transfers. The self-contained fold-and-lock construction speeds up packing lines and reduces the need for supplemental packaging supplies. Each mailer provides double-wall protection along the most vulnerable surfaces, making them appropriate for items that require more than a standard envelope but less than a full corrugated box.

Installation Notes

Assembly requires no tools or fasteners. Fold along the pre-scored lines and tuck the locking tabs to secure the mailer. Inspect each mailer before loading to confirm there are no tears or deformations that could compromise wall integrity. Store flat in a dry environment to prevent moisture absorption, which can reduce corrugated strength.
