Common questions
Will labels and stamps stick reliably to these mailers?
Yes. The white outer surface is specifically engineered for excellent adhesion with labels, stamps, and ink. The smooth polyethylene finish ensures your branding and shipping labels remain secure throughout transit.
How puncture and water resistant are these 2.5 mil mailers?
These mailers exceed standard puncture resistance requirements and provide comprehensive water protection during shipping. The 2.5 mil thickness with reinforced seams prevents tears and moisture penetration, even under rough handling conditions.
Can the tear strip be used repeatedly or is it single-use?
The tear strip is designed for single-use opening by recipients. The self-seal closure is permanent and tamper-evident, making it ideal for security-conscious e-commerce applications.
What's the minimum order quantity and cost per unit at bulk volume?
These mailers are sold in cases of 1,000 units. Bulk ordering reduces per-unit costs significantly, contact our sales team for volume pricing on multiple cases or custom order requirements.
