Mailing bags
Manufactured from recycled low-density polyethylene, these mailing bags offer strong resistance against moisture, tearing, and handling damage. The flexible polythene construction allows the bag to conform closely to contents, reducing excess bulk and supporting smoother processing through postal sorting systems and courier networks.
With a material thickness of 50 microns, also known as 200 gauge, these bags deliver a practical balance between strength and efficiency. This thickness is widely used for postal applications where durability is required without adding unnecessary weight. The result is packaging that protects contents while helping businesses manage shipping costs.
A permanent self-seal adhesive strip enables fast and secure packing without the need for additional tape or sealing materials. Once closed, the seal cannot be reopened without visible damage, providing a tamper-evident finish that supports secure delivery and customer confidence.
The opaque grey finish helps protect privacy by preventing visibility of contents during transit. This makes the bags particularly suitable for shipping clothing, accessories, textiles, and other soft goods where discretion and presentation matter.
These bags are widely used as shipping bags, parcel bags, and mailer bags across online retail, fulfilment centres, subscription services, and returns processing. Their lightweight construction supports efficient logistics while maintaining the durability expected for postal dispatch.
Produced using recycled materials, these bags support responsible packaging practices while continuing to meet commercial performance requirements. Businesses using packaging materials should ensure compliance with UK packaging waste regulations and maintain appropriate disposal and recycling processes.
Suitable for daily dispatch volumes or occasional shipping needs, these bags provide a practical packaging solution that aligns with the demands of modern ecommerce and postal distribution.

Packing guidance: ensure the item is dry and free from sharp edges, then place centrally so the seal area remains clean. Fold or compress soft goods to remove excess air and create a flat parcel profile. Peel the release liner and apply firm pressure along the full width of the closure for the strongest bond. For heavier contents, apply extra pressure at both corners and along the edges where handling stress is highest. These bags are ideal for dispatch workflows where speed matters, helping staff pack consistently without additional tape in most situations.
Storage and handling: keep unused stock in a cool, dry area away from direct sunlight and heaters to preserve adhesive performance. If you operate a returns process, these are a practical choice for replacement packaging, customer re-shipments, and repeat dispatch. Businesses commonly use this format for clothing orders, soft accessories, textiles, and non-fragile goods, where waterproof protection and discreet presentation are required. If you need a more rigid document solution, consider pairing with an internal board-backed insert for papers to maintain shape in transit.
