120G Polythene Bags
Clear Polythene Bags (Paper Wrapped) — Product Overview
These clear polythene bags are designed for straightforward, reliable protection and presentation of goods in storage, packing and distribution environments. Made from clear polythene film, they provide a practical barrier against dust and light handling marks while keeping contents visible for quick identification. The bags are supplied paper wrapped, helping keep packs tidy and easier to handle in busy packing areas.
This listing sits within the 120G (30 micron / 30mu) category, a commonly specified film grade for general-purpose packaging where clarity and everyday durability are required. Clear bags like these are widely used across retail, warehousing, e-commerce fulfilment, manufacturing and facilities teams that need a simple “bag-and-go” solution for protecting products, parts or paperwork.
Key Features
Clear film for fast identification
The transparent polythene makes it easy to see what’s inside without opening the bag, supporting quicker picking, checking and dispatch.
120G / 30mu film grade
This product is specified as 120G (30 micron), a popular thickness for general packaging tasks where you want a balance of flexibility and everyday strength.
Paper wrapped packs
Paper wrapping helps keep packs neat and protected during storage, and can make it easier to split packs or keep workstations organised.
General-purpose protection
Helps protect items from dust, light scuffs and handling marks during storage and transit, while maintaining a clean presentation.

Clear Poly Bags (Paper Wrapped) — Full Product Guide
Clear polythene bags are one of the most widely used packaging consumables because they are simple, cost-effective and adaptable. This guide explains what the specification means, how to choose the right option, and how to get the best performance from clear poly bags in day-to-day operations.
How It Works
Polythene bags provide a lightweight protective layer around products. The film acts as a barrier that helps reduce exposure to dust and minor surface contact. Because the film is clear, teams can visually confirm contents quickly—useful for picking, quality checks, returns processing and dispatch.
In many packing workflows, clear bags are used either as the primary pack (the item is bagged and labelled) or as an internal protective layer inside an outer carton, tote, or mailing bag.
Understanding the Specification (120G / 30mu)
This product is listed as 120G (30mu). In packaging, film thickness is commonly referenced in microns (mu). A 30 micron film is a popular general-purpose grade that offers a practical balance between flexibility and durability for everyday packing tasks.
Different suppliers may describe similar grades using either micron thickness or a “gauge / G” reference. The key point is that this listing is clearly positioned in the 120G / 30mu category, making it easier to match to existing specifications or reorder against a known grade.
Materials and Construction
These bags are made from clear polythene film. Polythene is widely used in packaging because it is lightweight, flexible and provides good clarity. The film is designed to be easy to handle and to conform around products without adding unnecessary bulk.
The bags are supplied paper wrapped, which helps keep packs clean and controlled during storage and handling. Paper wrapping can also help reduce loose film exposure on shelves and makes it easier to keep partial packs tidy.
Visibility and Presentation
Clear bags are often chosen when presentation matters or when you need to identify contents quickly. They can support:
• Faster picking: contents can be checked at a glance.
• Cleaner presentation: items look protected and organised.
• Reduced handling: fewer openings and re-bagging steps during checks.
If you label bags for stock control, the clear film also helps ensure labels and barcodes are easy to position and scan.
Choosing the Right Bag Size
Because Sapphire product pages can represent multiple variants, it’s best to choose a bag size that comfortably fits your product with a little allowance for easy loading. Consider:
- Product dimensions: measure the widest and longest points, including any protrusions.
- Loading method: hand packing may need more allowance than automated or jig-based packing.
- Air displacement: bulky items may trap air; leaving extra space can make sealing or closing easier.
- Label placement: allow a flat area for labels if required.
If you are replacing an existing bag, match both the nominal size and the film grade (here, 120G / 30mu) to maintain consistent performance.
Floor Type Compatibility (Where These Bags Fit in Your Operation)
These clear poly bags are compatible with a wide range of operational environments, including:
- Warehouse packing benches where speed and visibility are important
- Retail stockrooms for keeping items clean and grouped
- Manufacturing stores for parts protection and kitting
- Office and print rooms for document packs and printed sets
They are a simple consumable that can be integrated into existing packing processes without special equipment.
Health and Safety
As with all plastic bags and packaging film, use sensible handling and storage practices:
- Keep packaging away from heat sources and open flames.
- Store packs in a clean, dry area to maintain presentation and usability.
- Dispose of packaging responsibly in line with local waste and recycling guidance.
- Keep plastic bags away from children and vulnerable persons due to suffocation risk.
If you use these bags in a workplace setting, ensure staff follow site-specific safety procedures for packing stations and cutting tools (if used).
Ideal Applications and Use Cases
Clear polythene bags in a 30 micron grade are commonly used for:
- Product protection inside cartons: reduce dust and scuffing during transit.
- Grouping and kitting: keep sets of components together for assembly or dispatch.
- Returns processing: re-bagging items to keep them clean and identifiable.
- Retail presentation: protect items while keeping them visible.
- Document packs: keep paperwork clean and together with the product.
If your items have sharp edges or heavy weight, consider whether a thicker film grade is required for your application.
Maintenance, Cleaning and Care
These bags are a single-use packaging consumable and do not require maintenance. To keep them in best condition before use:
- Store in the original paper wrapping until needed.
- Avoid compressing packs under heavy loads to prevent creasing.
- Keep away from dusty areas if presentation is important.
For packing stations, keeping a clean bench surface helps maintain the clarity and appearance of the bagged product.
Case Study (Typical Workflow Example)
Scenario: A warehouse team dispatches mixed product lines daily and needs a quick way to protect items and reduce picking errors.
Approach: Items are placed into clear poly bags at the packing bench, allowing the packer and checker to confirm contents visually. A label is applied to the outside of the bag, and the bagged item is then placed into an outer carton with void fill as required.
Outcome: The team benefits from faster visual checks, cleaner presentation on arrival, and reduced rework caused by dust or handling marks.

Sizes Available
Sapphire product pages may include multiple size options within the same product family. Select the size variant that best suits your item and packing method. If you are matching an existing specification, confirm both the nominal bag size and the film grade (120G / 30mu) before ordering.
Need help choosing?
If you’re unsure which size or film grade is best for your application, consider testing a small quantity first to confirm fit, loading speed and protection level in your real packing workflow.
