Flyer Envelopes

Flyer Envelopes (Poly Mailers)
Flyer envelopes (poly mailers) have become increasingly popular in the postal and courier industry in recent years. They are manufactured from 100% recyclable, three-layer polyethylene film, offering excellent durability and protection.
The three-layer film provides enhanced strength, flexibility, and resistance to tearing, while also protecting the contents from moisture and environmental conditions.
The envelope flap is sealed with a high-quality hot-melt adhesive, ensuring a strong, permanent closure and maximum security for the contents. The side seams are automatically heat-sealed, providing exceptional strength and reliability. The envelopes are produced from virgin polyethylene, which meets health and safety standards for packaging applications.
