FAQs

What are poly mailers made from?

Poly mailers are manufactured using high-strength co-extruded polyethylene films. This material provides durability, flexibility, and enhanced tamper-proof security during transit.

They come with a hot-melt adhesive strip that creates a permanent seal. Once closed, the bag cannot be reopened without visible signs of tampering, ensuring shipment integrity.

Poly mailers are best suited for non-fragile items. For delicate products, we recommend using Qline Bubble Mailers, which provide added cushioning and protection.

Our Poly Mailers with POD Pouch include a dedicated transparent pocket for invoices, waybills, or other shipping documents, keeping paperwork secure, visible, and easy to track.
