Polythene Mailing Bag 320 x 440mm 50mm Flap 50mu Film Thickness Grey 500 per Box

MBG-320-440 Grey Polythene Mailing Bags (Box of 500)

Product Overview:

The MBG-320-440 provides an efficient, weatherproof dispatch envelope sized to protect everyday retail goods, clothing, and lightweight boxed items. Constructed from puncture-resistant 50-micron (mu) low-density polythene and finished with an integral 50mm self-adhesive flap, this medium-format mailer gives fulfilment centres and mail-order desks a rapid, tamper-evident packing method that cuts out excess postal weight.

Key Benefits:

• Discreet Opaque Film: Deep grey shade prevents internal items from being identified from the outside, maintaining delivery confidentiality for high-value orders.

• Moisture & Grime Protection: Low-density polythene creates an impermeable barrier against road spray, wet depots, and warehouse dust during transit.

• Permanent Self-Adhesive Lip: Strong 50mm peel-and-seal strip seals fast and tears visibly if unauthorised access is attempted, discouraging tampering.

• Tear-Resistant Durability: Flexible 50mu film flexes to accommodate irregular profiles, textiles, and shoe cartons without ripping at the seams.

• Postal Cost Minimisation: Ultra-thin and featherweight construction reduces parcel bulk and tare weight compared to rigid boxes, keeping courier costs low.
