300G - 400G Polythene Bags
Heavy Clear Poly Bags (Approx. 18 x 24 in / 457 x 610 mm) — Product Overview
These heavy-duty clear polythene bags are designed for reliable protection, presentation, and handling of a wide range of items. Made from strong clear film, they help keep products clean and contained while still allowing quick visual identification—ideal for busy packing benches, warehouses, workshops, and retail back-of-house environments.
This listing covers a heavy grade in the 300g–400g polythene bag range, with a stated thickness of 102 micron (102µ) (often referred to as a heavy gauge). The clear finish supports neat presentation for storage, distribution, and general packaging tasks where durability matters.
Key Features
Heavy-duty film (102µ)
A thicker polythene construction helps resist tearing and punctures during packing, handling, and storage—particularly useful for heavier or more angular items.
Clear for fast identification
The transparent material makes it easy to see contents at a glance, supporting quicker picking, checking, and dispatch.
Versatile bag format
A practical general-purpose bag style suited to many industries and workflows—from warehousing and fulfilment to manufacturing and retail operations.
Helps protect against dust and light moisture
Polythene bags are commonly used to keep items cleaner in storage and transit, reducing surface dust and minor contamination.
Convenient pack quantities
Supplied in trade-friendly packs to support regular use in packing stations and stockrooms.

Heavy Clear Poly Bags — Full Product Guide
Choosing the right polythene bag is about balancing protection, practicality, and presentation. A heavier micron rating is typically selected when you need extra confidence against tearing, when items have corners/edges, or when bags will be handled repeatedly through picking, packing, and distribution.
How It Works
Polythene bags provide a simple barrier around your product. Once items are placed inside, the bag helps keep them contained and protected from everyday handling risks such as scuffs, dust, and minor moisture exposure. The clear film also supports quick checks without opening the bag—useful for quality control, stock counts, and order verification.
Materials and Construction
These bags are made from clear polythene film in a heavy grade. The stated thickness is 102µ, which is commonly used where a stronger bag is required. Heavier film can improve performance in:
• packing lines where bags are opened and filled quickly
• storage where items may shift or press against the film
• distribution where parcels are handled multiple times
Because this is a clear bag, it also supports a clean, professional look for internal packaging and storage.
Understanding Thickness (Microns / “Gauge”)
Thickness is one of the most important indicators of bag strength. This product is listed at 102 micron. In many packaging contexts, micron thickness is used to compare durability across bag types. A higher micron value generally indicates a thicker, stronger film.
This listing also references the 300g–400g range for polythene bags. If you are matching an existing bag you already use, checking both the micron rating and the “heavy” classification can help ensure you select a comparable grade.
Size and Fit Guidance
The bag size is shown as 18 x 24 in (also stated as 457 x 610 mm). When selecting a bag size, consider:
- Product width and height (including any protrusions, handles, or irregular shapes)
- Extra room for easy loading if you are packing quickly or using gloves
- Whether you need space for labels, paperwork, or inserts inside the bag
- How tightly you want the bag to fit—a looser fit can reduce stress on seams and corners
If you are unsure, it’s often better to allow a little extra clearance so items slide in without forcing, especially with heavier or angular products.
Floor Type Compatibility
These bags are suitable for use across typical commercial environments including warehouses, packing benches, retail stockrooms, and light industrial settings. They work well with common packing workflows such as manual bagging, kitting, and order consolidation.
Health and Safety
As with all plastic bags, keep away from babies and children to avoid suffocation risk. In workplace settings, ensure bags are stored neatly to reduce slip/trip hazards and to keep packing areas tidy. If you are packing sharp-edged items, consider additional internal protection (such as wrapping or edge guards) to reduce puncture risk.
Ideal Applications and Use Cases
Warehousing & fulfilment
Use as an internal protective layer for items being picked and packed, or to keep multi-line orders grouped together.
Manufacturing & engineering
Useful for bagging parts, assemblies, and components to keep them clean between production stages.
Retail & wholesale
A practical option for back-of-house storage and for protecting stock from dust while keeping it visible.
Print, signage & promotional goods
Clear bags can help protect flat items and keep sets together while still allowing quick identification.
Maintenance, Cleaning and Care
Polythene bags are typically used as a consumable packaging item. Store packs in a clean, dry area away from direct heat sources and prolonged sunlight. Keeping bags in their original outer packaging until needed can help maintain cleanliness at the packing bench.
Case Study (Example Workflow)
A small fulfilment team dispatching mixed orders uses heavy clear poly bags to protect items before placing them into outer cartons or mailing bags. The clear film allows staff to confirm the correct item quickly, while the heavier thickness helps reduce split bags when orders include boxed goods or items with corners. This can reduce rework at the packing bench and help maintain a tidy presentation on arrival.
Who Is It For?
- Warehouses and stockrooms needing a strong, clear general-purpose bag
- Workshops and manufacturers bagging parts and components
- Retailers wanting visible protection for stored stock
- Operations that prefer a heavier film for more demanding handling
