300G - 400G Polythene Bags
Overview
These clear polythene (poly) bags are a heavy-duty option for protecting and presenting large items during storage, handling and transit. Made from clear polyethylene film, they provide a practical barrier against dust and general contamination while keeping contents visible for quick identification. This listing covers a range of pack quantities for the same style of bag, so you can choose the most suitable option for your operation without changing the product specification.
Often referred to as 300 gauge bags, the film thickness is also commonly expressed as 76 micron (76µm). This heavier grade is typically chosen when you need more puncture resistance and durability than standard light-duty poly bags, especially for bulky or awkward-shaped products.
Key Features
- Clear polyethylene film: Helps you identify contents quickly without opening the bag, supporting faster picking, packing and stock checks.
- Heavy-duty thickness (300 gauge / 76µm): A robust film grade designed for tougher handling and improved resistance to tearing compared with thinner bags.
- Large-format protection: Suitable for covering and enclosing larger items that won’t fit standard small poly bags.
- Simple, versatile packaging: A straightforward solution for storage, internal distribution, and dispatch preparation.
- Multiple pack options: Choose the pack quantity that best matches your throughput and storage space.
Typical Uses
- Protecting large products from dust and dirt during storage
- Bagging bulky items prior to dispatch or palletisation
- Keeping components grouped together for kitting and assembly
- Covering items in warehouses, workshops, and back-of-house areas
- General-purpose industrial and commercial packaging where visibility is helpful
Clear Poly Bags (300 Gauge / 76µm) — Full Product Guide
Clear poly bags are one of the most widely used packaging formats because they are cost-effective, quick to use, and adaptable across many industries. This heavier grade is aimed at applications where a stronger film is beneficial—particularly when items are large, have corners/edges, or will be handled multiple times before reaching the end user.
How It Works
The bag forms a protective enclosure around your product. Once the item is placed inside, the open end can be left open for temporary protection or sealed using a suitable closure method depending on your process. Because the film is clear, you can visually confirm the contents, condition, and any internal labels without opening the packaging—helpful for reducing handling time and avoiding mix-ups.
Materials and Construction
These bags are made from polyethylene (polythene) film. Polyethylene is commonly used for packaging due to its flexibility, moisture resistance, and ability to form a reliable barrier against dust and general contamination. The film is supplied in a clear finish to support product visibility.
Thickness terminology
You may see thickness described in different ways depending on industry preference:
- 300 gauge (often written as 300g in shorthand)
- 76 micron / 76µm
Both refer to the same heavy-duty film grade for this product.
Strength, Protection and Performance
Choosing a heavier film can improve day-to-day performance in busy packing environments. A thicker bag can help reduce the risk of tearing during loading, moving, or stacking—particularly when products are bulky or have edges that might stress the film. It also provides a more substantial feel, which can be useful when packaging is handled by multiple teams (goods-in, warehouse, packing, dispatch) before leaving site.
Visibility and Stock Control
Clear packaging supports efficient workflows. Teams can identify items quickly, confirm quantities, and check for damage without opening the bag. This can be especially useful for:
- Warehouse picking and put-away
- Returns processing and inspection
- Internal transfers between departments
- Batch control where visual checks are part of the process
Floor Type Compatibility
These bags are designed for packaging and storage rather than floor installation, so floor type compatibility is not applicable. However, they are commonly used in a wide range of environments including warehouses, workshops, retail stockrooms, and production areas.
Health and Safety
As with all plastic bags, safe handling and storage practices are important:
- Suffocation hazard: Keep plastic bags away from babies, children, and vulnerable individuals.
- Slip hazard: Loose plastic film can be slippery underfoot—keep work areas tidy and dispose of offcuts promptly.
- Manual handling: Large bags may be used with bulky items; follow your site’s manual handling guidance when lifting or moving packaged goods.
- Heat and ignition sources: Store away from excessive heat and open flames.
Ideal Applications and Use Cases
This heavy-duty clear poly bag format is typically selected for:
- Large items that need full coverage rather than partial wrapping
- Bulky products where a stronger film helps during insertion and removal
- Industrial and trade environments where packaging is handled frequently
- Storage protection for items that may sit on racking or pallets for extended periods
Maintenance, Cleaning and Care
Poly bags are typically single-use packaging, but good storage and handling can help maintain performance:
- Store bags in a clean, dry area to prevent contamination before use.
- Keep cartons closed until needed to reduce dust settling on the film.
- Avoid dragging bags across rough surfaces which can scuff or weaken the film.
- If using sealing equipment, ensure settings are appropriate for the film thickness to achieve a consistent seal.
Case Study (Example Workflow)
Warehouse dispatch protection for bulky stock
A warehouse team needs a quick way to protect large items prior to palletisation. By placing each item into a heavy-duty clear poly bag, the team reduces dust contamination during storage and staging. The clear film allows supervisors to verify the correct product is packed without opening the bag, helping reduce picking errors and rework. The heavier film grade supports repeated handling as items move from picking to packing to dispatch.

- Warehouses and distribution centres needing fast, visible protection for large items
- Manufacturers packaging products or assemblies prior to shipment or storage
- Retail and e-commerce operations that need clear bagging for stock control and dispatch prep
- Workshops and trade counters looking for a durable general-purpose bag

Need help choosing?
If you’re unsure whether this heavy-duty thickness is right for your application, consider the weight and shape of your product, how many handling steps it will go through, and whether you need extra puncture resistance compared with lighter poly bags.
