500G Polythene Bags
Clear Polythene Bags (Heavy Duty) — Product Overview
These clear polythene bags are designed for reliable protection, presentation and containment of goods where a tougher film is required. Made from clear polythene and supplied in convenient packs, they’re a practical choice for packing, storage, kitting and general handling across warehouses, workshops, retail back-of-house and light manufacturing environments.
The clear film helps with fast identification of contents without opening the bag, supporting efficient picking, packing and stock control. The heavier gauge construction is intended to provide improved puncture resistance and durability compared with lighter polythene bags, making them suitable for sharper-edged items, heavier components and products that need extra protection during handling.
Product on this page: Clear polythene bags in a heavy-duty gauge (500g / 127mu). This listing may represent multiple pack sizes and/or options.
Key Features
Clear film for easy identification
Transparent polythene allows contents to be checked at a glance, helping reduce handling time and improving accuracy in packing and dispatch.
Heavy-duty thickness (127 micron)
A thicker film is designed to offer greater strength and puncture resistance than standard light-duty bags, supporting more demanding packing tasks.
Versatile protection
Helps protect items from dust, light dirt and scuffs during storage and transit, and can be used as an inner liner or standalone bag depending on your process.
Simple, flexible packaging format
Polythene bags are easy to open, fill and handle, making them suitable for fast-paced packing benches and warehouse operations.
Neat presentation
Clear bags provide a clean, professional look for parts, components and products—useful for retail back-of-house, e-commerce fulfilment and kitting.

Clear Polythene Bags — Full Product Guide
Choosing the right polythene bag is about matching film thickness, bag dimensions and handling requirements to your application. This guide explains what the heavy-duty gauge means in practice, how to select the best option for your workflow, and how to get consistent results in packing and storage.
How It Works
Polythene bags provide a simple barrier around your product. Items are placed inside the bag to keep them together and protected from dust and light contamination. The clear film supports quick identification, which can reduce the need to open bags during picking, quality checks or stock counts.
In many operations, these bags are used as an inner protective layer inside cartons, mailing bags or outer packaging. They can also be used on their own for internal storage and organisation.
Materials and Construction
These bags are made from clear polythene film. Polythene is widely used for packaging because it is lightweight, flexible and resistant to tearing compared with many paper-based alternatives. The film thickness on this product is specified as 127 micron (also shown as 500g on the product title), indicating a heavier-duty grade intended for more demanding uses.
What does 127 micron mean?
Micron (µ) is a measure of film thickness. A higher micron value generally indicates a thicker, stronger film. A 127 micron bag is typically chosen when you want improved durability and puncture resistance compared with lighter bags.
Size and Fit (Choosing the Right Bag)
Bag size selection is important for both protection and packing speed. A bag that is too small can be difficult to load and may stress seams; a bag that is too large can waste material and reduce presentation quality.
- Measure your product: consider length, width and any protrusions or sharp corners.
- Allow clearance: add extra space for easy loading and to avoid stretching the film.
- Consider pack format: if you are bundling multiple items, size for the full kit.
- Think about closure: if you plan to tape, tie or heat seal (where applicable), allow enough excess film at the opening.
This Sapphire listing may cover multiple options; select the variant that best matches your required dimensions and pack quantity.
Strength, Protection and Handling
Heavy-duty polythene bags are commonly selected when:
- Items are heavier or have edges that could stress lighter film
- Products are handled frequently (picking, counting, repacking)
- You want a more robust inner pack for transit inside outer packaging
- Warehouse conditions require tougher packaging for day-to-day use
While polythene provides good general protection, it is not intended as a substitute for specialist barrier packaging where moisture vapour transmission, oxygen barrier or anti-static performance is required. If you need those properties, consider specifying a specialist film type.
Floor Type Compatibility
Not applicable for this product category. These are packaging bags intended for packing and storage applications rather than floor installation.
Health and Safety
- Keep away from children: plastic bags can present a suffocation hazard.
- Workplace handling: when packing sharp items, consider gloves and ensure the bag thickness is appropriate to reduce puncture risk.
- Storage: keep bags clean and dry to maintain presentation and reduce contamination risk.
Ideal Applications and Use Cases
Warehousing & fulfilment
Use as an inner protective bag for items going into cartons, or for organising pick faces and shelf stock. Clear film supports quick scanning and visual checks.
Workshops & maintenance stores
Ideal for keeping parts, fixings and components grouped and protected from dust and debris.
Retail back-of-house & e-commerce
A neat, clear presentation helps with product identification and packing accuracy, especially when multiple similar items are handled.
Kitting & assembly
Useful for bundling multi-part kits so all components stay together through assembly and dispatch.
Maintenance, Cleaning and Care
- Store in original packaging where possible to keep bags free from dust.
- Avoid prolonged exposure to heat sources that could distort the film.
- For best presentation, handle with clean hands or gloves in clean packing areas.
Case Study (Example Workflow)
A small fulfilment operation uses heavy-duty clear polythene bags to protect metal components before placing them into shipping cartons. The thicker film helps reduce punctures from edges during handling, while the clear material allows packers to confirm the correct part at a glance. This improves packing speed and reduces rework caused by mis-picks.
Who Is It For?
- Warehouses and stockrooms needing durable, clear inner packaging
- Workshops and maintenance teams organising parts and consumables
- Retail and e-commerce operations wanting quick identification and tidy presentation
- Businesses packing heavier items or products with edges that can stress lighter bags
