Eco & materials
These mailers use co-extruded recycled LDPE to balance strength with a lower material footprint. Not biodegradable or compostable. Please recycle via carrier-bag return points where available.
Strength & protection
The 60 µm film resists scuffs and handling damage better than economy grades, while the permanent adhesive creates a tamper-evident seal. The film is fully opaque for customer privacy.
Storage & performance
Store flat at 13–21 °C away from heat and sunlight. If stock arrives cold, allow it to reach room temperature before use for a consistent seal.
Lightweight = lower postage
Mailing bags reduce dead weight and keep parcels inside cheaper bands with Royal Mail, Evri and other couriers. Use inner cartons only for fragile presentation or very sharp edges.
