The BSC PREFERRED MAL12112 is a side-loading corrugated mailer designed to streamline packing operations in shipping and fulfillment environments. Constructed from 200/ECT-32-B white corrugated board, these one-piece mailers close securely with integrated locking tabs, eliminating the need for tape or additional fasteners. Each pack contains 50 mailers. The side-loading configuration allows for fast, efficient product insertion, making these mailers well suited for high-volume mailing and distribution tasks handled by warehouse staff, mailroom personnel, and shipping professionals.
These mailers are used in packaging and shipping applications where a clean, self-sealing corrugated solution is preferred. The one-piece construction reduces assembly time compared to multi-panel box designs. Typical applications include direct mail fulfillment, e-commerce order packaging, and internal document or product distribution. The white exterior surface also supports labeling and branding without additional prep work.
Designed as a general-purpose corrugated mailer for standard packaging and shipping applications requiring a self-closing, tape-free solution.
No tools are required for assembly or closure. Insert the item through the side-loading opening, then engage the locking tabs to seal the mailer. Ensure contents do not exceed the structural capacity of the 200/ECT-32-B board rating. Store unused mailers flat in a dry environment to maintain board integrity.
