120G Polythene Bags
Clear Poly Bags (120g / 30 micron) — Practical Protection for Packing, Storage & Dispatch
These clear polythene bags are a dependable, everyday packaging choice when you need a clean presentation and a simple way to protect items from dust, light moisture and handling marks. Made in clear film for easy identification of contents, they’re widely used across retail, ecommerce fulfilment, warehousing, workshops and offices for organising, packing and safeguarding products.
The film thickness is commonly described as 120 gauge (also referred to as 30 micron), offering a useful balance between flexibility and strength for general-purpose packing tasks. Clear poly bags are ideal when you want customers or staff to see what’s inside at a glance, while keeping items grouped, tidy and protected.
Key Features
Clear presentation: Transparent film helps with fast picking, stock checks and a professional look when packing items for customers.
General-purpose strength (120g / 30mu): A popular thickness for day-to-day packaging where you want more substance than very light film, without moving into heavy-duty grades.
Helps protect from dust and handling: Useful for keeping products clean during storage, packing and transit preparation.
Flexible and easy to use: Lightweight, simple to open and load, and easy to fold or tape closed depending on your process.
Versatile across industries: Suitable for retail, parts storage, fulfilment, print, light manufacturing and general workplace organisation.

Clear Poly Bags — Full Product Guide
Clear polythene bags are one of the most widely used packaging formats because they’re simple, cost-effective and adaptable. This guide explains what the specification means, how to choose the right option, and how to get the best performance from your bags in real-world packing environments.
How It Works
A poly bag provides a lightweight protective barrier around your product. The clear film allows the contents to remain visible, which can speed up picking and reduce packing errors. Depending on your workflow, bags can be used as inner protection inside cartons or mailing bags, or as standalone storage and organisation bags.
For many operations, clear poly bags are used to:
- Keep items grouped together (reducing lost parts and mixed stock)
- Protect surfaces from dust and light moisture exposure
- Improve presentation for customer orders and internal kits
Understanding Thickness: 120 Gauge vs 30 Micron
Polythene bag thickness is often described in either gauge or microns (µm). For this product, the thickness is listed as 120 gauge, which is also shown as 30 micron. These are two ways of describing the same film thickness.
What does that mean in practice?
- Everyday durability: 30 micron film is commonly chosen for general packing where you want a bag that feels substantial and resists minor snags better than very thin film.
- Good flexibility: The bag remains easy to open, load and fold, making it suitable for fast-paced packing benches.
- Balanced cost and performance: A popular choice when you need reliable protection without paying for heavy-duty thickness.
Materials and Construction
Clear poly bags are made from polythene film designed to be flexible and protective. The clear finish supports quick visual checks and helps maintain a clean, professional appearance in storage and dispatch areas.
Because these bags are supplied in a clear film, they’re especially useful where:
- Staff need to identify contents quickly without opening the bag
- Customers benefit from seeing the product through the packaging
- Stock control relies on fast visual confirmation
Choosing the Right Bag Size (Without Guesswork)
When selecting a poly bag, allow enough room for the product to slide in easily without stretching the film. As a general rule, choose a bag width that comfortably exceeds the product’s widest point, and a length that allows space for closure (fold-over, tape, label, or other sealing method).
If you’re packing items with sharp corners or edges, consider:
- Allowing extra clearance so the film isn’t under tension
- Using protective inner wrap for corners
- Stepping up to a heavier thickness if snag resistance is critical
Closure Options and Packing Methods
Clear poly bags can be closed in several practical ways depending on your process:
- Fold-over and tape: A quick method for temporary closure or internal protection.
- Labels: Useful for identification, barcoding and batch control.
- Heat sealing: If your operation uses heat sealers, poly bags can often be sealed for a tamper-evident finish (where applicable to your workflow and equipment).
For ecommerce dispatch, many businesses use a clear poly bag as an inner protective layer inside a mailing bag or carton to help keep products clean and presentable.
Ideal Applications and Use Cases
Because they’re clear, lightweight and easy to handle, these bags suit a wide range of environments:
- Retail and ecommerce: Packing items neatly, protecting products before they go into outer packaging.
- Warehousing: Organising stock, separating SKUs, and simplifying picking.
- Workshops and maintenance: Storing parts, fixings and components to reduce loss and contamination.
- Print and office: Keeping documents, brochures and printed materials clean during handling and storage.
- Light manufacturing: Kitting components and protecting finished items before boxing.
Health and Safety Considerations
As with all plastic bags, keep poly bags away from babies and young children due to suffocation risk. In workplace settings, ensure bags are stored neatly to reduce slip/trip hazards and keep packing areas organised.
If you are packaging food, medical items, or products with specific compliance requirements, confirm suitability for your application and any relevant regulations before use.
Maintenance, Cleaning and Care
Poly bags are designed for convenience and are typically used as a consumable packaging item. To keep your packing process efficient:
- Store bags in a clean, dry area away from direct heat sources
- Keep cartons or packs closed until needed to reduce dust contamination
- Use clean hands or gloves when packing items that must remain pristine
Case Study: Improving Pick Accuracy in a Busy Stock Room
A common challenge in busy stock rooms is mixed items and unclear identification during picking. Switching to clear poly bags for grouping components and labelling kits can help teams reduce picking errors and speed up order assembly. Because the contents remain visible, staff can verify items quickly without opening each pack, supporting smoother workflows during peak periods.

- Warehouses and stores teams looking to improve organisation and visibility
- Ecommerce fulfilment operations that want a clean presentation and quick identification
