500G Polythene Bags
3x4 Clear Poly Bags (Approx. 76 x 102mm) — Heavy-Duty Protection for Small Items
These clear polythene bags are designed for neat, reliable packaging of small products, components and samples where you want the contents visible at a glance. The compact 3x4 format (approximately 76 x 102mm) is ideal when you need a tidy presentation and a practical barrier against dust, light handling marks and general contamination during storage, picking and dispatch.
Made from clear polythene, these bags provide a simple, cost-effective way to organise and protect items in warehouses, workshops, retail back rooms, studios and home workspaces. The heavier film option in this range is commonly chosen when you want a more robust feel than lightweight poly bags, helping reduce splitting and punctures in everyday use.
Key Features
Clear visibility:
Transparent film helps you identify contents quickly without opening the bag—useful for stock control, order picking and reducing handling time.
Compact 3x4 size (approx. 76 x 102mm):
A practical small-bag format for parts, samples and small retail items. This size is commonly used where larger bags would look untidy or waste space.
Heavy-duty film option (listed as 500G / 127mu):
Chosen for added durability compared with thinner polythene bags, helping the bag hold its shape better and resist tearing during normal packing and handling.
Neat presentation for packing and storage:
Creates a clean, professional look for internal organisation or customer-facing packaging where appropriate.
Versatile general-purpose polythene:
Suitable for a wide range of non-hazardous items and everyday packaging tasks across many industries.

3x4 Clear Poly Bags — Full Product Guide
Choosing the right polythene bag is about balancing presentation, protection and practicality. This guide explains what to consider when selecting a compact clear poly bag in a heavier film option, and how to get the best results in day-to-day packing.
How It Works
Polythene bags provide a simple physical barrier around your item. Once the contents are placed inside, the bag helps reduce exposure to dust and light surface contamination during storage and handling. Because the film is clear, you can visually confirm the contents quickly—helpful for fast-moving environments where accuracy and speed matter.
For many businesses, small clear bags are also a key part of kitting (grouping multiple components into one pack) and order consolidation (keeping small items together so they don’t get lost in a carton or mailer).
Materials and Construction
These bags are made from clear polythene. Polythene is widely used in packaging because it is lightweight, flexible and economical. It also offers good everyday resistance to moisture and handling compared with paper-based wraps.
The listing identifies this option as 500G / 127mu. In packaging, thickness is often referenced in microns (mu). A heavier film is typically selected when you want a sturdier bag that feels more substantial and is less prone to tearing in normal use.
Clarity and finish:
Clear film supports quick identification and a tidy presentation. This can reduce the need for opening packs during checks, which helps maintain cleanliness and reduces rework.
Size and Fit Guidance (3x4 / approx. 76 x 102mm)
Bag sizing is usually stated as width x length. The 3x4 format is compact and best suited to small items. For best results:
- Allow clearance: choose a bag that gives a little extra room around the item so it slides in easily.
- Consider thickness and shape: bulky or sharp-edged items may need more space and/or a heavier film to reduce puncture risk.
- Think about labels: if you plan to apply labels, ensure there is a flat area available without covering key visibility.
If you are packing multiple pieces together (for example, a small kit of fixings), consider the combined volume and whether the bag needs extra length for folding or sealing.
Protection and Performance
Clear poly bags are commonly used to:
- Keep items together and prevent loss of small components
- Reduce dust and light surface contamination during storage
- Provide a clean, consistent presentation for internal or customer-facing packing
While polythene offers practical everyday protection, it is not a substitute for specialist barrier packaging where you need controlled moisture transmission, anti-static performance, or certified food-contact compliance. If your application requires a specific certification or performance property, choose a product explicitly stated for that purpose.
Floor Type Compatibility
This product is a packaging consumable and does not have floor type compatibility requirements.
Health and Safety
As with all plastic bags, keep away from babies and small children due to suffocation risk. In workplace settings, ensure bags are stored neatly to avoid slip hazards and to keep packing areas organised.
If you are packing items with sharp edges, consider additional protection (such as wrapping the item first) to reduce puncture risk and to protect handlers.
Ideal Applications and Use Cases
Warehousing & fulfilment:
Use small clear bags to separate SKUs, protect accessories, and keep multi-part orders organised. Clear visibility helps reduce picking errors and speeds up checks.
Engineering, maintenance and trade counters:
Ideal for organising fixings, connectors and small spares. Bags can be labelled for quick identification and stored in bins or drawers.
Craft, hobby and studio work:
Useful for beads, findings, small cut pieces, and keeping sets together. Clear film makes it easy to see colours and shapes without opening.
Retail back rooms:
Helps keep small items clean and presentable, especially when items are handled frequently during stock counts or merchandising.
Maintenance, Cleaning and Care
These bags are intended as a packaging consumable. Store them in a clean, dry area away from direct heat sources and sharp objects. Keeping bags in their outer carton or protective wrap until use helps maintain cleanliness and reduces the chance of dust settling inside.
For best packing results:
- Use clean, dry hands or gloves when packing items that must remain pristine
- Avoid overfilling—leave enough space to close, fold or seal as required
- Keep sharp items from rubbing against the film during transit by adding a small wrap or backing card
Case Study (Example Workflow)
Scenario: A small e-commerce business ships replacement parts and accessory kits.
Challenge: Small components were getting mixed up in cartons, and pickers had to open packs to confirm contents.
Approach: Each kit was grouped into a clear 3x4 poly bag, labelled with the SKU and quantity, then placed into the shipping carton.
Result: Faster picking and checking, fewer missing-part claims, and a cleaner presentation on arrival—without adding significant weight or cost.
This is a typical way compact clear bags are used to improve organisation and reduce errors in fulfilment.
