300G - 400G Polythene Bags
Clear Polythene Bags (Heavy Duty)
These clear polythene bags are designed for protecting, storing and presenting larger items where you want strong film, good clarity and a dependable seal option (tape, heat seal or tying, depending on your process). Made from clear polythene and supplied in bulk packs, they’re a practical choice for warehouses, eCommerce fulfilment, manufacturing, laundry/linen handling and general storage where contents need to stay clean, dry and visible.
Key Features
Clear, easy-to-identify contents
Transparent film helps you quickly confirm what’s inside without opening the bag—useful for picking, packing, stock checks and returns processing.
Heavy-duty thickness (76 micron)
A thicker polythene film provides improved puncture resistance and durability compared with lighter bags, helping reduce splits and tears during handling and transit.
Large format protection
The generous bag format is suited to bulky or long items, grouped components, textiles, and products that need full coverage to keep dust and moisture off.
Versatile closure options
Depending on your workflow, these bags can be closed using tape, ties, staples, or heat sealing (where appropriate). This flexibility makes them suitable for both temporary storage and dispatch.
Clean presentation for packing and storage
Clear poly gives a neat, professional look for internal distribution, customer orders, or organised storage—especially when paired with labels or barcodes.
Bulk supply for operational efficiency
Supplied in trade packs to support regular use in busy environments, helping you standardise packaging and reduce re-order frequency.

Clear Polythene Bags — Full Product Guide
Choosing the right polythene bag is about balancing clarity, strength, size and how you plan to close and handle the bag. This guide explains what a heavier clear poly bag is best for, how thickness affects performance, and how to get the most reliable results in day-to-day packing and storage.
How It Works
Polythene bags create a simple protective barrier around your product. The film helps shield contents from dust, light splashes and general handling. Because the bag is clear, you can identify items quickly—ideal for fast-moving operations where speed and accuracy matter.
In many workplaces, clear poly bags are used as an “outer protection layer” around boxed goods, textiles, or grouped components. They can also be used as a standalone pack for items that don’t require a rigid carton.
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 consistent protective wrap. The clarity of the film supports scanning labels and barcodes and makes it easier to spot the correct item during picking.
Thickness matters: at 76 micron, the film is in a heavier-duty range, offering improved resistance to tearing and puncturing compared with thinner alternatives. This can be especially helpful when packing items with corners, folds, or uneven shapes.
Strength, Thickness and Handling
Micron (µ) is a common way to describe film thickness. A higher micron value generally indicates a thicker, stronger film. In practical terms, heavier film can:
- Reduce the chance of splits when inserting products
- Hold up better during repeated handling (picking, moving, stacking)
- Offer more confidence for storage and internal distribution
That said, the best thickness depends on what you’re packing. If you’re packing lightweight, soft goods, you may not need heavy film. If you’re packing heavier items or anything with edges, a thicker bag can help reduce waste and rework.
Closure Options (and Choosing the Right One)
Clear poly bags are commonly closed in several ways. The best method depends on whether you need a temporary closure, a tamper-evident finish, or a sealed pack for storage:
- Tape: quick and convenient for short-term closure and dispatch preparation.
- Ties / bag neck sealing: useful for bulky contents where you want to gather the opening.
- Staples: sometimes used for internal packing (ensure staples won’t damage contents).
- Heat sealing: where suitable, provides a clean, secure seal for storage or distribution.
If you plan to heat seal, ensure your sealing equipment is compatible with the film and that your process settings are tested for consistent results.
Floor Type Compatibility
These bags are suitable for use across typical workplace environments including warehouses, packing benches, production areas and stockrooms. For best results, store bags in a clean, dry area and keep them away from sharp edges or hot surfaces that could damage the film.
Health and Safety
- Choking hazard: polythene bags can present a suffocation risk—keep away from babies and children.
- Manual handling: when packing large or heavy items, use safe lifting practices and avoid overfilling.
- Workplace safety: keep loose bags away from walkways to reduce slip/trip risks.
Ideal Applications and Use Cases
Warehousing & stock protection
Use clear poly bags to keep stock clean on shelves or pallets, especially for items that attract dust or need to remain presentable.
Textiles & laundry
A popular choice for protecting linens, uniforms, garments and soft furnishings during storage and distribution.
Manufacturing & kitting
Ideal for grouping parts, assemblies or kits so they stay together and can be identified at a glance.
eCommerce fulfilment
Useful as an inner protective layer inside cartons or mailing bags, helping keep products clean and organised.
Maintenance, Cleaning and Care
Polythene bags are typically single-use or limited re-use depending on your application. To maintain performance:
- Store flat in original packaging to prevent creasing and contamination.
- Keep away from direct heat sources and prolonged sunlight.
- Use clean hands or gloves when packing items that must remain pristine.
Case Study (Typical Workflow Example)
A warehouse team handling bulky textile items uses heavy-duty clear poly bags to protect goods after quality inspection. Items are placed into the bag, a label is applied to the outside for scanning, and the opening is closed with tape for short-term storage. When orders are picked, the team can confirm the correct item visually and by barcode without opening the bag, reducing handling time and helping keep products clean until dispatch.
Who is it for?
- Warehouses and distribution centres needing clear, durable protective bags
- Manufacturers and assembly operations that kit or bundle components
- Laundry, linen and textile services requiring clean presentation and protection
- Retail and eCommerce teams wanting visibility and tidy packing
