Discontinued Stationary
Short description
These grey opaque poly mailers are designed for fast, secure dispatch of non-fragile items. The opaque film helps keep contents private in transit, while the tough polythene construction is made to cope with everyday handling through pick, pack and courier networks.
Key Features
Opaque grey film for privacy
The grey, non-see-through material helps conceal the contents of each parcel, supporting discreet delivery for retail, fulfilment and returns.
Durable polythene construction
Made from strong polythene film (70 micron), these mailers are intended to resist tearing and punctures during normal warehouse handling and distribution.
Large-format capacity
The generous face size and flap provide room for bulky soft goods and larger boxed items, helping reduce the need for secondary outer packaging in many dispatch workflows.
Simple, fast packing workflow
Poly mailers are a popular choice for high-throughput packing benches because they are lightweight, quick to fill, and easy to label.
Lightweight to help control shipping costs
Compared with rigid cartons, polythene mailers add minimal dead weight, which can help keep postage and courier charges under control (depending on carrier pricing).
Professional presentation
A clean, uniform grey finish gives parcels a consistent look across shipments—useful for brands, marketplaces and multi-site operations.

No8 24x36+2 - 280g Grey Opaque Poly Mailers — Full Product Guide Introduction
Grey opaque poly mailers (also commonly called courier bags or mailing bags) are a practical packaging choice when you need a tough, lightweight outer that protects goods and keeps them out of sight. This listing covers a configurable product that may be supplied in different pack quantities; the core specification remains the same: a large-format grey opaque polythene mailer made from 70 micron film.
How It Works
Poly mailers are designed to act as an outer shipping layer. You place the item inside the bag, remove excess air where possible, and seal the flap (where applicable). A shipping label is then applied to the outside. The opaque film helps prevent the contents being visible, while the polythene provides a barrier against light moisture and scuffs encountered during handling.
Materials and Construction
Material: Polythene (poly) film.
Colour: Grey, opaque.
Thickness: 70 micron film.
Polythene mailers are widely used because the material is flexible, lightweight and resilient. The 70 micron thickness is commonly selected for dispatch environments where parcels may be handled multiple times from warehouse to final delivery.
Protection and Performance (What to Expect)
These mailers are intended to provide:
- Privacy: Opaque film helps conceal contents.
- Surface protection: Helps protect items from scuffs and light dirt.
- Moisture resistance: Polythene provides a basic barrier against rain splashes and damp handling (not a substitute for fully waterproof inner protection for sensitive goods).
- Handling durability: Designed to resist tearing under normal packing and courier conditions.
For fragile products, consider adding internal protection (e.g., bubble wrap, paper cushioning, or an inner carton) before placing the item into the mailer.
Floor Type Compatibility
Not applicable—this is a packaging product rather than a flooring product. In warehouse terms, these mailers are compatible with typical packing environments including bench packing stations, conveyor-fed fulfilment lines, and manual pick/pack operations.
Health and Safety
- Packaging safety: Keep polythene bags away from babies and small children to avoid suffocation risk.
- Workplace handling: Use safe cutting tools if opening cartons or trimming labels; keep packing areas clear to reduce slips and trips.
- Storage: Store in a clean, dry area away from direct heat sources to maintain film performance.
Ideal Applications and Use Cases
These large-format grey opaque mailers are best suited to items that benefit from a lightweight outer and do not require rigid protection. Common use cases include:
- Fashion & apparel: Coats, hoodies, multiple garments per order, and bagged clothing.
- Home textiles: Bedding, towels, curtains and soft furnishings (when appropriately packed).
- Marketplace fulfilment: High-volume dispatch where speed and consistency matter.
- Returns: Providing customers with a simple outer for sending goods back.
Maintenance, Cleaning and Care
Poly mailers are single-use shipping consumables and do not require maintenance. For best results:
- Keep packs sealed until needed to prevent dust contamination.
- Avoid prolonged exposure to direct sunlight or high heat during storage.
- Use clean hands/gloves at the packing bench to keep parcels presentable.
Case Study (Example Workflow)
Scenario: An e-commerce fulfilment team dispatches apparel orders daily and wants a consistent, discreet parcel presentation while keeping packing time low.
- Pick items and place into an inner protective bag if required.
- Insert into the grey opaque poly mailer and remove excess air.
- Seal the flap (where applicable) and apply the shipping label.
- Sort parcels by carrier route for collection.
Outcome: Faster packing compared with boxing many soft goods, improved privacy for customers, and reduced packaging weight.
Who is it for?
- Online retailers shipping soft goods and non-fragile items
