Express Bags
Conquer the cold with our Arctic-Grade Cold Resistant Poly Mailers. Specifically engineered for high-latitude regions and cold-chain logistics, these mailers remain flexible and durable at temperatures as low as -40°C. Unlike standard bags that become brittle and crack in freezing conditions, our specialized PE blend maintains its superior tensile strength and adhesive integrity, ensuring your products arrive safely even in the harshest winter climates.

FAQ
Standard PE bags undergo a "glass transition" at low temperatures, making them brittle like glass. They often shatter or burst along the seams during transit in winter. Our Arctic-grade bags remain flexible, absorbing impact rather than cracking.
Yes. We use a specialized cold-weather adhesive with a lower glass transition point. It remains "tacky" and creates a destructive seal even when applied in temperatures that would cause regular glue to fail.
