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.
How do poly mailers ensure product security?
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.
Are these poly mailers suitable for fragile items?
Poly mailers are best suited for non-fragile items. For delicate products, we recommend using Qline Bubble Mailers, which provide added cushioning and protection.
