500G Polythene Bags
Clear Polythene Bags (5 x 7 / 127 x 178mm) — 500g (127 micron) Overview
These clear polythene bags are a practical, everyday packaging choice when you need a clean presentation, quick packing, and reliable protection from dust and light handling. Made in a heavier 500g grade (commonly referenced as 127 micron / 127mu), they’re designed for packing, storing, and organising a wide range of small items while keeping contents visible for fast identification.
Because these bags are transparent, they’re ideal for stockrooms, fulfilment benches, workshops, and retail back-of-house environments where speed matters. The open-top format keeps packing simple: insert the product, remove excess air if needed, and close using your preferred method (for example, tape, labels, or heat sealing where appropriate for your process).
Key Features
Clear, easy-to-identify packaging
The transparent film helps you quickly confirm contents without opening the bag—useful for picking, packing, and inventory control.
500g / 127 micron (127mu) polythene
This listing is in the 500g range, shown as 127mu (127 micron). The thicker film is suited to general handling and helps reduce the risk of tearing compared with lighter grades.
Convenient small-item size
The 5 x 7 inch format (approx. 127 x 178mm) is a versatile size for many small products, components, and accessories.
Simple open-top design
An open-top bag keeps packing fast and flexible—ideal when you want to choose your own closure method depending on the job.
Neat presentation for retail and dispatch
Clear poly bags can improve presentation for items that benefit from being seen (and kept clean) during storage, display prep, or shipping.

5x7 - 500g Clear Poly Bags (127x178mm - 127mu) — Full Product Guide
Choosing the right polythene bag is usually about balancing three things: the internal size you need, the thickness that suits your handling requirements, and the packing workflow you want on the bench. This guide explains what the 5 x 7 inch clear poly bag in a 500g / 127mu grade is best suited for, and how to get the most from it in day-to-day use.
How It Works
These are flat, open-top polythene bags. You place the item inside, then close the opening using the method that best fits your process. Many businesses use labels or tape for quick closure, while others may use heat sealing equipment where a sealed finish is required for presentation or to reduce the chance of items escaping during transit.
Materials and Construction
This product is listed as a clear polythene bag in the 500g range, shown as 127 micron (127mu). Polythene film is widely used in packaging because it is lightweight, flexible, and provides a simple barrier against dust and light scuffing during handling. The clear finish supports fast identification and helps reduce packing errors.
Thickness Guide (What “500g / 127mu” Means)
On Sapphire Packaging, this item is categorised as 500G (127mu). Micron (mu) is a common way to describe film thickness. A higher micron figure generally indicates a thicker, more robust bag. If you’re comparing options across suppliers, note that some sellers describe thickness in different units (for example, mil). Always compare the stated thickness value and intended use rather than relying on naming alone.
Size and Fit (5 x 7 inch / 127 x 178mm)
The listed size is 5 x 7 inches, shown as 127 x 178mm. When selecting a bag size, allow room for the product’s width and height, plus any extra space needed for easy insertion and closure. If your items have sharp corners or bulky shapes, consider allowing additional clearance or selecting a larger size to reduce stress on the seams.
Floor Type Compatibility
Not applicable—this is a packaging consumable rather than a flooring product.
Health and Safety
As with many plastic packaging products, keep bags away from babies and young children due to suffocation risk. In workplace settings, store packaging neatly to reduce slip/trip hazards and keep packing areas clear. If you use heat sealing equipment, follow your equipment’s operating guidance and site safety procedures.
Ideal Applications and Use Cases
Stockrooms and warehouses: Use clear bags to keep SKUs separated and visible, helping speed up picking and cycle counts.
Workshops and engineering stores: Useful for organising small components and keeping them clean between jobs.
Retail and e-commerce fulfilment: A tidy way to present and protect items before they go into an outer mailer or carton.
Office and facilities: Handy for organising small supplies and keeping sets together.
Maintenance, Cleaning and Care
These bags are designed for packaging use and are typically treated as consumables. Store them in a clean, dry area away from excessive heat and direct sunlight to help maintain film performance. Keep cartons closed when not in use to reduce dust contamination in packing environments.
Case Study (Example Workflow)
A small parts distributor uses clear 5 x 7 inch bags at the picking bench to separate multi-line orders. Each line item is bagged and labelled, allowing the packer to visually confirm contents before placing them into the final shipping carton. The clear film reduces mis-picks, while the heavier 500g / 127mu grade helps the bags hold up during handling and internal transfers.
Who Is It For?
- Businesses that need fast, visible packaging for small items
- Warehouses and stockrooms that benefit from clear identification
- Workshops that want a simple way to organise and protect components
- Retail and e-commerce operations looking for clean presentation before outer packing
