A3 Courier Poly Mailer 310 × 420 mm, 50 µm, 50 pcs with antistatic strip

Durable poly mailer in A3 (310 × 420 mm) format for fast and secure parcel packing. Thanks to the 50 µm thickness, opaque design, strong adhesive, and a self-adhesive closure with an antistatic strip, it speeds up dispatch and protects the contents during transport. The pack contains 50 pcs.

An A3-size plastic courier envelope (poly mailer) is ideal for e-shops, pickup points, and companies that need to reliably pack larger and bulkier goods. The envelope is designed to be closed quickly, withstand normal handling during transport, and at the same time keep the contents discreet.

The practical antistatic strip significantly makes packing easier – the film does not stick to your hands and removing the release liner is instant. The 50-micron thickness provides a balanced ratio of flexibility and strength, so the mailers resist tearing and abrasion even in more demanding conditions.

Main advantages:

Self-adhesive closure with strong glue – once sealed, it cannot be opened without damage, providing higher protection against unauthorized opening.
Opaque design – discreet shipping (black inside, light outer surface).
Durable 50 µm material – higher strength and good protection during transport.
Suitable for couriers and parcel lockers – fast packing and lower volume compared to cardboard boxes.

Use: outerwear (jackets, coats), footwear, backpacks, sports and travel accessories, larger multi-item orders, children’s goods, plush toys, or pillows.
