120G Polythene Bags
Clear Polythene Bags (120g / 30mu) — Protective, Transparent Packaging for Large Items
These clear polythene bags are designed to provide a simple, reliable way to protect products from dust, light handling marks and general contamination during storage, picking and distribution. Made from clear polythene film in a 120g / 30 micron (30mu) grade, they offer a practical balance of flexibility and protection while keeping contents visible for quick identification.
Because this is a configurable product listing, options may vary by pack quantity and size. The core benefit remains the same: a clear, protective outer bag that helps keep goods clean and presentable from warehouse to end user.
Key Features
Clear visibility:
Transparent film helps you identify contents quickly without opening the bag—useful for stock control, picking accuracy and presentation.
120g / 30mu film grade:
A commonly specified thickness for protective poly bagging where you want a sturdier feel than very light film, while still retaining flexibility for packing and handling.
Protects against dust and handling:
Helps shield items from dust, scuffs and light moisture exposure during storage and transit (not intended as a fully waterproof or airtight barrier unless sealed appropriately).
Paper wrapped supply:
Supplied paper wrapped, helping keep bags tidy and easier to handle in storage areas.
Versatile packaging format:
Suitable for a wide range of non-food and general packaging tasks where a clear outer bag is required.

Clear Polythene Bags (120g / 30mu) — Full Product Guide
Clear poly bags are one of the most widely used packaging formats because they are quick to use, cost-effective and adaptable. This guide explains what the 120g / 30mu specification means in practical terms, how these bags are typically used, and what to consider when choosing the right option for your operation.
How It Works
A polythene bag provides a protective outer layer around your product. The bag can be used as a simple dust cover, a protective sleeve for storage, or as part of a packing process where items are bagged before being placed into cartons, sacks or on pallets.
Because the film is clear, you can visually confirm the contents, labels or barcodes without opening the packaging. This can reduce handling time and help maintain product condition.
Materials and Construction
These bags are made from clear polythene film. Polythene is valued in packaging for its flexibility, toughness and resistance to tearing compared with many paper-based alternatives. The film thickness is specified as 30 microns (30mu), and the listing also references a 120g grade. Together, these specifications indicate a protective bag intended for general packaging and storage tasks where a more substantial film is preferred.
As with most poly bags, performance depends on how the bag is used—sharp edges, heavy point loads or abrasive products may require additional protection or a heavier gauge.
Film Thickness Explained (30mu)
Micron (µm) is a standard way to describe plastic film thickness. A 30 micron film is commonly used where you want a noticeable protective layer that still remains easy to handle and fold. Thicker films generally provide improved puncture resistance and durability, while thinner films can be more economical and easier to conform tightly around products.
If you are comparing options, keep in mind that thickness is only one factor—film formulation and manufacturing quality also influence strength and tear resistance.
Paper Wrapped Supply — What It Means in Practice
Paper wrapped packaging typically helps keep the bags clean and organised prior to use. In busy packing areas, this can make it easier to store and dispense bags without them becoming dusty or tangled. It can also help maintain a tidy presentation in storage locations.
Floor Type Compatibility
This product is packaging rather than a flooring product, so floor compatibility is not applicable. However, in warehouse environments, clear poly bags are commonly used alongside racking, shelving and pallet storage systems. For best results, store bags in a clean, dry area away from direct heat sources and sharp objects that could damage the film.
Health and Safety
As with all plastic bags, safe handling and storage are important:
- Keep plastic bags away from babies and young children due to suffocation risk.
- Use appropriate manual handling practices when bagging large or heavy items.
- If sealing bags (with tape, ties or heat sealing where applicable), ensure the method suits your process and does not create sharp edges or hazards.
- Dispose of packaging responsibly in line with local recycling and waste guidance.
Ideal Applications and Use Cases
Clear polythene bags in this grade are typically chosen when you need a dependable protective cover with good visibility. Common use cases include:
- Warehousing and distribution: protecting goods from dust during storage and transit.
- Manufacturing and assembly: bagging components, sub-assemblies or finished items to keep them clean between process steps.
- Retail and e-commerce: keeping products presentable and protected while allowing customers or staff to see the item.
- Facilities and maintenance: covering equipment parts or supplies to prevent contamination.
- Document and print protection: where a clear protective sleeve is useful (ensure suitability for your specific materials and storage conditions).
Maintenance, Cleaning and Care
Poly bags are typically single-use or limited re-use depending on your process. To get the best performance:
- Store flat and avoid crushing to reduce creasing and sticking.
- Keep away from excessive heat and direct sunlight for prolonged periods.
- Avoid contact with sharp edges; consider adding corner protectors for boxed items with sharp corners.
- If re-using, inspect for punctures or tears before re-packing.
Case Study (Typical Workflow Example)
Scenario: A warehouse dispatch team needs to keep large items clean and easy to identify while they wait for pallet consolidation.
Approach: Items are placed into clear poly bags immediately after picking. Because the film is transparent, staff can confirm the correct SKU and any internal labels without opening the packaging. Bagged items are then staged for dispatch, reducing the risk of dust contamination and helping maintain a clean presentation on arrival.
Outcome: Faster visual checks, fewer handling marks, and improved consistency in packing.
Who Is It For?
- Warehouses and fulfilment centres needing quick, visible protective packaging
