300G - 400G Polythene Bags
Heavy Clear Poly Bags — Product Overview
These heavy-duty clear polythene bags are designed for protecting, storing and handling larger items where a stronger film is preferred. The clear material helps with quick identification of contents, while the heavier grade provides added resistance for day-to-day packing, warehousing and distribution tasks.

Heavy Clear Poly Bags — Full Product Guide
Heavy clear poly bags are a practical choice when you need a simple protective outer layer with improved strength compared with lighter polythene bags. They are commonly used to keep items clean, grouped and easier to manage throughout storage and distribution. Because the film is clear, teams can identify contents quickly without opening the bag—helpful for busy packing benches and warehouse aisles.
This listing is for heavy clear polythene bags in a large format. The product title includes both imperial and metric dimensions, along with the film thickness in microns, so you can match the bag to your internal specifications and packing process.
How It Works
These bags provide a protective barrier around the item(s) placed inside. In typical workflows, the bag is used to:
- Keep products clean and protected from dust during storage
- Group multiple components together to reduce picking errors
- Provide a simple outer layer for handling and internal movement
Because the film is transparent, the bag can support faster identification and checking—particularly useful where items are similar but not identical.
Materials and Construction
The bags are made from clear polythene film and supplied as a heavy grade. The specification on this product indicates a thickness of 102 microns (102µ), which is commonly used to describe a heavy-duty film suitable for more demanding packaging tasks.
Polythene is widely used in packaging because it is lightweight, flexible and provides a practical protective layer for many non-food and general-purpose applications.
Understanding Thickness (Microns)
Film thickness is often stated in microns (µ). A higher micron value generally indicates a thicker, stronger film. This product is listed at 102µ, placing it in a heavier category intended for improved durability during handling.
If you are comparing products across suppliers, always compare the stated thickness (microns) and the bag dimensions to ensure you are matching like-for-like.
Size and Fit Guidance
To choose the right bag size, consider:
- Product width and height: allow enough room for easy insertion without forcing the item into the bag.
- Bulk and shape: bulky or irregular items may require extra allowance beyond the flat dimensions.
- Grouped packs: if bundling multiple items, account for the combined thickness and edges.
This listing includes the bag dimensions in both inches and millimetres in the title to help you confirm compatibility with your packing requirements.
Ideal Applications and Use Cases
Heavy clear poly bags are commonly used in:
- Warehousing and distribution: for protecting items on shelves, in totes, or during internal transfers.
- Manufacturing and assembly: for keeping parts and sub-assemblies grouped and clean.
- Retail and e-commerce operations: for back-of-house storage, returns processing, and general packing tasks.
- Facilities and maintenance stores: for organising supplies and protecting items from dust.
Health and Safety
As with many packaging bags, take care to keep polythene bags away from babies and small children due to suffocation risk. In workplace settings, ensure bags are stored neatly to reduce slip/trip hazards and to keep packing areas organised.
If you are using bags in regulated environments (for example, where specific material compliance is required), confirm suitability against your internal standards before use.
Maintenance, Cleaning and Care
These bags are typically used as a consumable packaging item. To keep them in good condition prior to use:
- Store in a clean, dry area away from excessive heat
- Keep cartons closed until needed to reduce dust contamination
- Avoid placing heavy loads on top of stored bags to prevent deformation
Case Study (Typical Workflow Example)
Scenario: A warehouse team needs to protect large items and grouped components during storage and picking.
- Items are bagged after goods-in checks to keep them clean on racking.
- Clear film allows pickers to confirm the correct item quickly without opening packaging.
- The heavier film helps reduce damage from routine handling and movement between locations.
This type of workflow can help improve stock presentation and reduce time spent checking contents.
Who Is It For?
- Warehouses and fulfilment centres needing clear, robust protective bags
- Manufacturers and assemblers organising parts and components
- Retail stockrooms and e-commerce operations handling varied product lines
- Any business that needs a heavier-grade clear polythene bag for general packaging
