Partners Brand MLR4 Corrugated Mailers White Pack of 50

Pack of fifty corrugated mailers

This pack contains fifty white corrugated mailers sized at 6 1/2" x 4 7/8" x 3 3/4". They are designed for shipping small items that need rigid protection in transit. The pack quantity suits businesses or individuals who send regular batches of parcels. Each mailer arrives flat and assembles without tape.

Lightweight structure for low-cost postage

The single-wall corrugated board keeps the package light so postage costs stay down while still resisting crushing. The white exterior gives a clean surface for labels and branding. No internal padding is included, so fragile contents need their own wrap. The mailers are supplied new and ready to use.

Rigid walls hold shape under stacking

Under sustained load the corrugated flutes maintain their profile and prevent the mailer from collapsing when heavier parcels are stacked on top. The glued seams stay sealed through normal handling and temperature changes. They are not waterproof, so prolonged exposure to moisture will weaken the board. Buyers who need water resistance or internal cushioning should look elsewhere.
