120G Polythene Bags
Overview
These clear polythene bags are a simple, reliable way to protect and present flat items. Supplied paper-wrapped for convenient handling and storage, they’re designed for everyday packing tasks where you want a clean, transparent finish and a consistent film thickness.
The bag is made from clear polythene film in a 120g / 30 micron (30mu) grade, giving a practical balance of clarity and durability for general-purpose use. The transparent material helps with quick identification of contents, while the smooth film helps items slide in easily during packing.
Key Features
Clear presentation
Transparent polythene helps you display or identify contents at a glance—useful for picking, packing, and retail presentation.
General-purpose 30mu film
A 30 micron (30mu) thickness is a popular choice for routine protection against dust, light scuffs, and handling marks.
Paper-wrapped supply format
Paper-wrapped packs help keep bags tidy in storage and make it easier to issue stock to packing benches.
Neat fit for flat items
The proportions suit a wide range of flat products such as prints, stationery, leaflets, and small components—without needing to oversize the bag.

4x8 - 120g Clear Poly Bags — Full Product Guide
Clear polythene bags are one of the most widely used packaging formats because they’re quick to use, cost-effective, and adaptable across many industries. This listing covers a clear bag in a 120g / 30mu grade, supplied paper-wrapped, intended for general-purpose protection and presentation of flat items.
How It Works
These bags act as a protective outer layer around your product. You place the item inside the bag to create a barrier against dust and everyday handling. Because the film is clear, you can still see labels, barcodes, and product details without opening the pack—helpful for stock control and order accuracy.
In many packing workflows, clear poly bags are used as:
- An inner bag to keep products clean before they go into a carton or mailing bag
- A presentation sleeve for retail-ready items where visibility matters
- A parts bag to keep small items grouped together and easy to count
Materials and Construction
The bag is made from clear polythene film. Polythene is valued in packaging for its flexibility, moisture resistance, and ease of use. The 120g / 30mu specification indicates a commonly chosen grade for everyday packing tasks where you want a dependable film without moving into heavy-duty thicknesses.
Because the film is smooth and flexible, it typically:
- Allows quick loading during packing
- Conforms neatly around flat items
- Provides a clean, professional appearance
Choosing the Right Thickness (30mu)
Film thickness is one of the most important factors when selecting a poly bag. A 30 micron (30mu) bag is often chosen for general-purpose protection—thick enough to feel substantial in hand, while still remaining easy to handle and economical for higher-volume packing.
If you’re comparing options, consider:
- Product weight and edges: sharper corners or heavier items may benefit from thicker film
- Handling intensity: frequent picking/packing can justify a more robust grade
- Presentation needs: clarity and a smooth finish can improve perceived quality
Paper-Wrapped Packs: Why It Matters
Paper-wrapped packaging is a practical format for busy packing environments. It helps keep bags aligned and protected in storage, reduces the chance of loose bags becoming creased or contaminated, and makes it easier to issue consistent quantities to workstations.
Paper-wrapped packs can be especially useful when:
- You store multiple bag sizes and want quick identification
- You want to keep packing benches tidy
- You need to control stock usage by issuing set pack quantities
Floor Type Compatibility
Not applicable—this is a packaging consumable rather than a flooring product. However, for warehouse and packing areas, these bags are well suited to bench packing, shelving, and standard dispatch operations.
Health and Safety
As with all plastic bags, keep away from babies and children to avoid suffocation risk. In a workplace setting, store bags in their paper-wrapped packs until needed to reduce loose film on floors and benches. If you use these bags in conjunction with sealing equipment or cutting tools, follow your site’s standard safe working procedures.
Ideal Applications and Use Cases
These clear poly bags are a strong fit for organisations that need a clean, consistent bag for flat items and light-to-medium duty protection. Common use cases include:
- Retail and e-commerce: keeping products clean and presentable while maintaining visibility
- Print and stationery: protecting leaflets, cards, and documents from dust and handling
- Manufacturing and assembly: bagging parts, kits, and components for organisation
- Warehousing: grouping items for picking and reducing mix-ups
Maintenance, Cleaning and Care
These bags are designed as a consumable packaging item and do not require maintenance. For best results:
- Store in a clean, dry area away from direct heat sources
- Keep packs paper-wrapped until use to reduce dust and creasing
- Use the oldest stock first (simple FIFO rotation) to keep packaging consistent
Case Study (Example Workflow)
Scenario: A small e-commerce operation dispatches printed stationery and small flat accessories. Items need to stay clean and look professional on arrival.
Approach: Each item is placed into a clear poly bag to protect against dust and handling marks during picking and packing. The bagged item is then placed into an outer mailing pack or carton depending on the order.
Result: Faster packing (easy loading and visibility), fewer presentation issues, and improved consistency across shipments.
