300G - 400G Polythene Bags
Heavy Duty Clear Polythene Bags (Approx. 150 x 200mm / 6 x 8in) — Product Overview
These heavy duty clear polythene bags are designed for reliable, everyday packing where you want a strong film, a neat presentation and quick visual identification of contents. The clear material helps you check items at a glance, while the heavier gauge construction is suited to packing, protecting and organising a wide range of products in retail, warehouse, workshop and fulfilment environments.
This listing covers a heavy grade clear poly bag in the popular 6 x 8 inch class (metric nominal size shown as 150 x 200mm) with a thickness of 102 microns (102µ). This is commonly referred to as “400 gauge” in packaging thickness terminology. Please select the pack quantity that best suits your operation.
Key Features
Heavy duty 102µ film (approx. 400 gauge):
A thicker polythene film helps the bag resist tearing and punctures during handling, making it a dependable choice for packing items that are heavier, have corners/edges, or will be moved through multiple touchpoints (pick, pack, dispatch, storage).
Clear for fast identification:
The transparent finish supports quick stock checks and accurate order picking. It also presents products cleanly for retail back-of-house, kitting, and internal distribution.
Popular small-format size:
The 6 x 8 inch class is a versatile size for small parts, components, accessories, samples and general packing. The metric nominal size (150 x 200mm) is the nearest standard equivalent to 6 x 8 inches.
Simple, flexible packaging solution:
Poly bags are lightweight, space-efficient to store, and easy to use at the bench or packing station. They can be paired with labels, inserts and documentation for tidy presentation.
Suitable for many packing workflows:
Ideal for organising, protecting and grouping items for storage, shipping, assembly lines, returns processing and inventory control.

Heavy Clear Poly Bags — Full Product Guide Introduction
Choosing the right polythene bag is about balancing clarity, strength and practicality. A heavier gauge clear bag is often selected when standard light-duty bags feel too thin for the job, or when you want extra confidence during packing and transit. Below is a practical guide to help you decide if this heavy clear poly bag is the right fit for your workflow.
How It Works
These bags provide a simple protective sleeve around your product. Items are placed inside to keep them grouped together and shielded from dust, light scuffs and general handling. The clear film allows barcodes, labels and product details to remain visible, supporting faster picking and fewer packing errors.
In many operations, poly bags are used as an inner pack (inside a mailing bag or carton) to keep order lines separated and tidy. They can also be used as a standalone protective bag for storage and internal distribution.
Materials and Construction
This product is a clear polythene bag made from a heavier film thickness of 102 microns (102µ). Thickness is one of the most important indicators of durability: a thicker film generally offers improved resistance to tearing and puncturing compared with lighter grades.
Packaging thickness is sometimes described in “gauge”. While gauge terminology can vary by market, 102µ is commonly referred to as approximately 400 gauge. If you are comparing products across suppliers, checking the micron value is the most reliable way to match thickness.
Size Guidance (Nominal Size vs. Inches)
The size shown for this product is 150 x 200mm, which aligns with the common 6 x 8 inch class. Because 6 x 8 inches converts to approximately 152 x 203mm, many packaging suppliers use the nearest nominal metric size (150 x 200mm) for standardisation.
When selecting a bag size, consider not only the flat dimensions of the item but also its thickness/bulk. If your product is bulky, you may need to step up a size to allow comfortable insertion and to avoid stressing the film at the seams.
Strength and Protection (Why Heavy Gauge Matters)
Heavy gauge poly bags are often chosen for:
- Sharper edges or corners: thicker film can help reduce punctures during insertion and handling.
- Heavier contents: improved tear resistance supports more confident lifting and movement.
- Busy packing environments: where bags are opened, filled and moved quickly, a stronger film can reduce split bags and rework.
While no bag is indestructible, selecting a heavier micron rating is a straightforward way to increase robustness without changing your packing process.
Floor Type Compatibility
Poly bags are used across many environments—warehouse floors, packing benches, retail stockrooms and workshops. For best results, store bags in a clean, dry area and dispense them from a box or rack to keep them free from dust and to maintain a smooth packing flow.
Health and Safety
As with all plastic bags, keep away from babies and children due to suffocation risk. In workplace settings, ensure loose packaging is managed to reduce slip/trip hazards and keep packing areas tidy. If you are using labels or inserts, ensure they are applied securely so they do not detach during handling.
Ideal Applications and Use Cases
This heavy clear poly bag is a strong all-rounder for:
- Retail & e-commerce: grouping items, protecting products, and keeping paperwork with the order line.
- Manufacturing & assembly: kitting components and keeping sets complete.
- Engineering & maintenance: organising parts and consumables for jobs and call-outs.
- Office & facilities: storing small items, samples, and supplies.
If you need a bag that is easy to identify contents through, but you also want a more substantial feel than light-duty film, this thickness is a sensible choice.
Maintenance, Cleaning and Care
Poly bags are typically single-use or limited re-use depending on your application. To keep your packing process consistent:
- Store bags away from direct heat and sunlight.
- Keep cartons closed until needed to reduce dust contamination.
- Dispense from a clean surface or dedicated dispenser to avoid snagging.
- Do not overload—choose a larger size if insertion feels tight.
Case Study (Example Workflow)
Scenario: A small fulfilment team ships multi-line orders containing accessories and small components.
Challenge: Items can separate in the carton, and paperwork can be misplaced. Light-duty bags occasionally split when packed quickly.
Solution: Using a heavy gauge clear poly bag for each order line keeps items grouped, protects surfaces from scuffs, and allows quick visual checks. The thicker film reduces split bags during fast packing, helping maintain throughput and presentation.
Result: A tidier pack, fewer repacks, and faster picking verification thanks to clear visibility.
Who Is It For?
- Warehouses and fulfilment operations that want a stronger clear inner pack
- Retail stockrooms needing quick identification and neat presentation
- Workshops and engineers organising parts and consumables
- Small businesses looking for a dependable, versatile clear bag
Colours / Features Available
This product is supplied as a clear polythene bag to support visibility of contents. If you require tinted, printed, or specialist closure options, consider browsing alternative bag styles within the wider polythene bag range.
Sizes Available
This listing is for the 6 x 8 inch class bag (nominal 150 x 200mm) in a heavy 102µ thickness. Sapphire product pages may include multiple pack quantities as selectable variants—please choose the option that matches your required volume.
If you are unsure which size you need, a practical approach is to measure your item’s width and length, then allow extra room for the item’s thickness and for easy insertion. For bulky items, stepping up to the next size can improve packing speed and reduce stress on the film.
