Poly Mailers for Moisture Protection

These blue polyethylene mailers measure 10 x 13 inches and come in a pack of 100. They are designed to protect shipped products from moisture during transit. The coloured exterior helps packages stand out while the silver inner lining adds a layer of discretion. Strong seams keep contents secure even when the mailer is fully packed.

Self-Seal Closure and Label Adhesion

Each mailer features a self-sealing strip that closes without tape or additional supplies. The outer surface accepts labels, stamps and ink cleanly so addressing stays legible. This combination reduces packing time and ensures the shipping information remains attached throughout the delivery journey.

Durable Polyethylene Build

The high-strength polyethylene construction resists tearing and punctures during handling. Coloured blue on the outside with a silver interior, the material shields items from damp conditions. The sealed seams maintain integrity under pressure, making these mailers suitable for regular shipping volumes where reliability matters.

Questions about this item

Will the self-seal adhesive on these 10 x 13" mailers lose stickiness over time?

The self-seal closure is designed for single-use shipping; once sealed the mailer is not intended to be reopened or resealed.

At what point will the polyethylene material tear if a mailer is over-packed?

High-strength seams are built to keep contents intact even when the mailer is filled beyond normal capacity.

Do the blue 100-pack mailers become too hot to handle when left in sunlight all day?

Polyethylene mailers can warm in direct sun but remain safe to touch; the silver inner lining helps reflect heat away from contents.
