120G Polythene Bags
Clear Poly Bags (Approx. 4" x 6" / 102 x 152mm) — 120 Gauge (30µ) Packaging Bags
These clear polythene (poly) bags are a practical, everyday packaging choice when you need a clean presentation and a simple way to protect items from dust, handling marks and light moisture during storage, picking and packing. Made from clear polyethylene film, they allow the contents to be identified quickly without opening the bag—ideal for busy stock rooms, eCommerce fulfilment benches and retail back-of-house environments.
This listing covers clear poly bags in the 4" x 6" size range (approx. 102 x 152mm) manufactured in 120 gauge film, which is commonly referenced as 30 microns (30µ). That thickness is a popular “all-rounder” for light-to-medium duty bagging where you want a balance of clarity, flexibility and tear resistance.
Key Features
Clear presentation:
Transparent film helps you showcase or identify products at a glance—useful for order accuracy, stock control and retail display preparation.
120 gauge / 30µ thickness:
A widely used thickness for general packaging. “120 gauge” is commonly used interchangeably with “30 micron (30µ)” for polythene film, helping you match existing packaging specs and re-order with confidence.
Fast, simple packing:
Lightweight bags that are easy to open, fill and handle—ideal for high-throughput packing stations.
Protects against dust and handling:
Helps keep items clean and reduces scuffs or marks during storage and internal transit.

Clear Poly Bags — Full Product Guide
Choosing the right poly bag is mostly about matching the bag size and film thickness to your product and process. Below is a practical guide to help you decide if 120 gauge (30µ) clear poly bags are the right fit for your application.
How It Works
Poly bags provide a simple protective barrier around your product. The clear film keeps the contents visible while helping to reduce contamination from dust and debris. In day-to-day operations, they’re commonly used to group items, keep order lines together, and protect products while they move through storage, picking, packing and dispatch.
Materials and Construction
These bags are made from clear polyethylene film (polythene). Polyethylene is widely used in packaging because it is lightweight, flexible and offers good clarity. The film thickness for this product is specified as 120 gauge, which is commonly referenced as 30 microns (30µ).
Understanding thickness terms:
Packaging suppliers often describe polythene thickness using either “gauge” or “microns.” For this product type, 120 gauge is commonly used interchangeably with 30µ (30 micron). If you are matching an existing spec sheet or reordering a previously used bag, checking both terms can help ensure you get the same feel and performance.
Size and Fit Guidance
The listed size is in the 4" x 6" range (approx. 102 x 152mm). When selecting a bag size, allow enough room for the product to slide in easily without forcing, especially if the item has corners, edges, or is packed in multiples. If you are bagging several items together, consider the combined thickness and shape of the bundle.
Tip:
If your product is close to the bag’s internal dimensions, moving up to the next size can speed up packing and reduce the risk of tearing during insertion.
Film Thickness: What 120 Gauge / 30µ Means in Practice
Film thickness influences how the bag feels and performs:
- Thinner films can be more economical and are often used for very light items or short-term protection.
- Mid-range films like 120 gauge / 30µ are commonly chosen for general-purpose packaging where you want a dependable bag without excessive bulk.
- Thicker films may be preferred for heavier items, sharper edges, or where extra puncture resistance is needed.
For many businesses, 120 gauge / 30µ is a “go-to” thickness because it balances flexibility with everyday durability.
Ideal Applications and Use Cases
Clear poly bags in this size and thickness are often used for:
- Small parts and components: keeping items grouped and easy to identify.
- Order consolidation: keeping multi-line orders together during picking.
- Retail preparation: protecting items before they go onto shelves or into customer packaging.
- Work-in-progress protection: covering items between production steps.
Health and Safety
As with all plastic bags, keep away from babies and children to avoid suffocation risk. In warehouse and packing environments, ensure bags are stored neatly to prevent slips or trips and to keep packing stations organised.
Maintenance, Cleaning and Care
Poly bags are typically used as a single-use packaging component. 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 can help maintain cleanliness and reduce static-related dust attraction.
Case Study (Example Workflow)
Scenario: A small eCommerce operation ships multiple small items per order (e.g., accessories, spares, or craft components).
Approach: Items are picked into clear poly bags so the packer can verify contents visually. The bagged items are then placed into the final mailing packaging.
Result: Faster packing checks, fewer picking errors, and improved presentation when customers open the parcel.
