120G Polythene Bags
Clear Polythene Bags (Approx. 40 x 30 in / 1016 x 762mm) — Product Overview
These clear polythene bags are a large-format, lightweight packaging option designed for protecting, grouping and presenting items while keeping contents visible. The listing indicates a bag size of approximately 40 x 30 inches (1016 x 762mm) and a film thickness of 30 micron (often referenced in the trade as 120 gauge). Clear polythene is widely used across warehousing, fulfilment, retail back-of-house and manufacturing environments because it provides a practical barrier against dust and light handling marks while remaining quick to pack and easy to identify at a glance.
Because this is a configurable product page, pack quantities and pricing may vary by option. The core specification remains focused on a clear bag in a large size with a 30 micron film, suitable for general-purpose protection and presentation where a heavy-duty film is not required.
Key Features
Clear visibility:
Transparent film helps you identify contents quickly without opening the bag—useful for picking, packing, stock checks and returns processing.
Large-format coverage:
The approximate 1016 x 762mm footprint provides generous internal space for bulky, flat or grouped items that won’t fit standard small poly bags.
30 micron film (trade equivalent often described as 120 gauge):
A lightweight thickness intended for everyday protection, keeping packaging material use efficient while still offering a practical barrier for storage and transit handling.
General-purpose protection:
Helps shield products from dust, light scuffs and incidental contact during storage, internal movement and distribution.
Simple, versatile packaging:
Clear polythene bags are easy to integrate into most packing workflows and can be used as an outer protective bag, an inner liner, or a grouping bag depending on your process.

Clear Polythene Bags (Approx. 40 x 30 in / 1016 x 762mm, 30 micron) — Full Product Guide
Choosing the right polythene bag is mostly about matching size, film thickness and how you intend to use it. This guide explains what the specification on this listing means in practical terms, how a 30 micron clear bag typically performs, and what to consider when selecting options on a configurable product page.
How It Works
A clear polythene bag provides a simple protective enclosure around your product. Once the item is placed inside, the bag acts as a barrier between the contents and the surrounding environment. In day-to-day operations this can help reduce dust settling on products, minimise light surface marking from contact, and keep grouped items together so they move through your process as a single unit.
Clear film also supports faster handling: packers and warehouse staff can confirm contents visually, which can reduce the need to open packaging during checks, picking, or returns processing.
Materials and Construction
This product is described as a polythene bag with a clear finish. Polythene film is commonly used for flexible packaging because it is lightweight, cost-effective and easy to handle. The listing specifies a thickness of 30 micron. Thickness is one of the most important indicators of how a bag will feel and perform in use.
Understanding thickness terms:
Some suppliers describe thickness in microns (µm), while others use gauge. The web references for similar products commonly note that 30 micron is approximately 120 gauge. If you are comparing suppliers, always check whether they quote in microns or gauge and confirm you are comparing like-for-like.
What 30 micron typically implies:
A 30 micron bag is generally considered a lightweight film suitable for everyday protective packaging. It is often chosen when you want a practical barrier without the extra material cost and stiffness of heavier films. If your application involves sharp edges, heavy items, or high abrasion, you may need a thicker film—however, for many general packing and protective uses, 30 micron is a common choice.
Size and Fit (Why Orientation Matters)
The listing indicates 40 x 30 inches and provides the metric equivalent 1016 x 762mm. Bag sizes are often presented as width x length, but different sellers may swap the order depending on how they describe orientation (for example, some may list the same bag as 30" x 40"). When selecting a size, focus on the two dimensions and how they relate to your product’s footprint and thickness.
Practical sizing tips:
- Measure your product at its widest and longest points, including any protrusions.
- Allow clearance for easy insertion—especially if you are packing quickly or packing multiple items together.
- If the contents have depth (thickness), consider whether you need extra room for the bag to wrap around the item comfortably.
Floor Type Compatibility (Warehouse & Packing Environments)
While polythene bags are not floor products, they are often used in environments where handling conditions vary. In warehouses and packing areas, bags may be placed on benches, racking, trolleys or conveyors. Clear polythene helps maintain visibility even when items are staged for dispatch. For best results, keep bags away from sharp surfaces and avoid dragging filled bags across rough floors to reduce the chance of scuffing or puncture.
Health and Safety
As with all flexible plastic packaging, safe handling is important:
- Suffocation hazard: Keep plastic bags away from babies, children and vulnerable individuals.
- Workplace handling: If packing at speed, ensure staff have adequate space and avoid overfilling bags which can increase the risk of tearing.
- Storage: Store bags in a clean, dry area to keep them free from dust and contamination prior to use.
If you have a regulated application (for example, food contact or medical use), confirm the required compliance and certification for the exact variant you intend to purchase.
Ideal Applications and Use Cases
Large clear polythene bags are commonly used wherever you need a quick protective cover with easy identification. Typical use cases include:
- Warehousing and distribution: Protecting items on shelves or pallets from dust and light handling marks.
- E-commerce fulfilment: Grouping multiple items or components into one visible pack for accuracy.
- Manufacturing and assembly: Keeping kits, parts or sub-assemblies together between process steps.
- Retail back-of-house: Protecting stock in storage while keeping labels and contents visible.
- General storage: Covering items that benefit from a clean, transparent outer layer.
Maintenance, Cleaning and Care
Polythene bags are typically supplied ready to use and do not require cleaning. To maintain performance and presentation:
- Keep bags sealed in their outer packaging until needed to reduce dust build-up.
- Avoid heat sources and prolonged direct sunlight during storage, which can affect plastics over time.
- Do not overload beyond what the film thickness can comfortably handle; if you see stretching or stress whitening, consider a thicker option.
Case Study (Example Workflow)
Scenario: A warehouse team needs to protect wide, flat items during internal movement and short-term storage while keeping them easy to identify.
Approach: Items are placed into clear large-format polythene bags at goods-in. The clear film allows staff to confirm the correct item without opening the packaging. Bags are then staged on racking for picking. During dispatch preparation, the bag provides a clean protective layer until the final outer packaging step.
Outcome: Reduced handling marks and fewer identification errors, with minimal additional packing time.
Who Is It For?
- Businesses that want simple, clear protective packaging for storage and handling
- Operations that benefit from fast visual identification of contents
- Warehouses, manufacturers and retailers needing a large bag format
