150G Polythene Bags
3x6 Clear Block Bottom Poly Bags (150 Gauge / 38 Micron) — Product Overview
These clear block bottom polythene bags are designed for neat, practical packing where you want a compact bag that can stand more easily than a flat bag when filled. The block bottom construction helps the bag form a stable base, making it a popular choice for packing small items for storage, presentation, and dispatch. Manufactured in clear polythene, they allow quick visual identification of contents without opening the bag—useful for busy packing benches, stock rooms, and order fulfilment.
This listing covers a block bottom poly bag style supplied in a 150 gauge film (approximately 38 micron). That thickness is commonly chosen when you need a balance of flexibility and everyday durability for light-to-medium duty packing tasks. The clear finish supports tidy presentation and efficient picking, while the block bottom shape helps maximise usable internal space for certain product shapes.
Key Features
- Block bottom design: Creates a more stable base when filled, helping the bag sit more upright for easier loading and presentation.
- Clear polythene film: Contents remain visible for fast identification, stock control, and quality checks.
- 150 gauge / ~38 micron thickness: A practical everyday thickness that balances strength and flexibility for general packing.
- Space-efficient storage: Supplied as loose bags that store compactly and dispense quickly at the packing station.
- Clean, professional appearance: Suitable for retail-style presentation as well as warehouse and despatch use.
Typical Uses
- Small parts and components (e.g., fixings, fittings, craft parts, samples)
- Retail and e-commerce packing where visibility helps picking accuracy
- Organising items in workshops, storerooms, and stock rooms
- Protecting products from dust and handling marks during storage
- General-purpose bagging for light-to-medium duty applications
Clear Block Bottom Poly Bags — Full Product Guide
Choosing the right polythene bag is about more than just length and width. Bag style, film thickness, and how the bag will be filled all affect performance in real-world use. This guide explains what a block bottom bag is, why 150 gauge (around 38 micron) is a common choice, and how to select and use this style effectively across packing, storage, and fulfilment workflows.
How It Works
A block bottom bag is formed so that the base opens into a flat “block” shape when the bag is filled. Compared with a standard flat bag, this construction can:
- Help the bag stand more easily on a bench or shelf once filled
- Make loading simpler because the mouth can open more naturally
- Provide a more box-like internal volume for certain product shapes
In day-to-day packing, this can translate into faster bagging and a tidier finished pack—especially when you are packing multiple small items and want them to sit neatly rather than bunching at the bottom.
Materials and Construction
These bags are made from clear polythene film. Polythene is widely used in packaging because it is lightweight, flexible, and provides a practical barrier against dust and light moisture. The clear finish supports visibility and presentation, while the block bottom construction is designed to improve stability and usable space.
Film thickness: This product is specified as 150 gauge, which is approximately 38 micron. Gauge and micron are two ways of describing film thickness; micron is a metric measurement, while gauge is a commonly used packaging term. In practical terms, 150 gauge / ~38 micron is often selected for general-purpose packing where you want a dependable bag without moving into heavy-duty film.
Floor Type Compatibility
While “floor type compatibility” is more commonly discussed for mats and flooring products, the equivalent consideration for block bottom bags is surface and workflow compatibility—how the bag behaves on benches, packing tables, conveyors, and shelving.
- Packing benches and tables: The block bottom helps the bag sit more stably during filling, reducing the need to hold the bag open continuously.
- Shelving and storage bins: Clear film supports quick identification; the block bottom shape can help filled bags stack more neatly depending on contents.
- Pick-and-pack environments: Visibility and easy loading can improve speed and reduce picking errors.
Health and Safety
As with all plastic packaging, safe handling and appropriate use are important:
- Suffocation hazard: Keep plastic bags away from babies, young children, and vulnerable individuals.
- Workplace safety: Keep loose bags away from heat sources and moving machinery; ensure packing areas are tidy to reduce slip/trip risks from discarded film.
- Product suitability: If you are packing food, medical items, or products with specific compliance requirements, confirm the correct grade/specification for your application before use.
Ideal Applications and Use Cases
Block bottom poly bags are particularly useful when you want a small bag that loads easily and presents well. Common scenarios include:
- Retail presentation: Clear bags show the product clearly, while the block bottom can help the pack look more structured.
- Samples and kits: Useful for assembling small kits where multiple components need to be kept together and visible.
- Parts organisation: Ideal for workshops and maintenance teams who need to separate and label small parts.
- Order fulfilment: Helps keep small items grouped and protected inside a larger parcel.
If your items have sharper edges or higher weight, consider whether a thicker film is required for your specific use. For everyday light-to-medium packing, 150 gauge / ~38 micron is a widely used option.
Maintenance, Cleaning and Care
These bags are designed for packaging use and are typically single-use or limited re-use depending on the application. To keep them performing well:
- Store in a clean, dry area: Keep away from dust, direct sunlight, and excessive heat to maintain film quality.
- Avoid overfilling: Leave enough headspace to close or seal the bag as required.
- Prevent punctures: For items with corners or edges, consider additional internal protection or a heavier gauge bag.
Case Study (Typical Packing Workflow)
Scenario: A small e-commerce business ships mixed small items (e.g., accessories, spare parts, or craft components). The team needs a bag that keeps items together, looks tidy, and allows quick checking during picking.
Approach: Items are grouped into clear block bottom bags at the pick bench. Because the bag can sit more stably when filled, the packer can load items quickly. The clear film allows a second person to verify contents at a glance before the order is placed into an outer mailer or carton.
Outcome: Faster packing, fewer picking errors, and a more consistent presentation—without adding unnecessary bulk to the parcel.
Who Is It For?

Colours / Features Available
This product is supplied in clear polythene for visibility and presentation. If you require tinted, printed, or specialist films (e.g., anti-static), those are typically separate product lines—choose based on your handling and compliance needs.
Sizes Available
This product page represents a specific size option within a broader range of polythene bags. If you need a different width/length or a different film thickness, check the related bag categories or contact us for guidance on the closest equivalent. For applications where exact fit matters (e.g., kitting, retail presentation, or automated packing), selecting the right size and thickness can improve both appearance and efficiency.
