500G Polythene Bags
Clear Bottom-Weld Polythene Bags (Paper Wrapped)
These clear, heavy-duty bottom-weld polythene bags are designed for reliable protection, tidy presentation, and efficient packing. The bottom-weld (bottom seal) construction helps the bag hold its shape and supports the contents from the base, while the clear film makes it easy to identify items at a glance. Supplied paper wrapped for convenient handling and storage, these bags are a practical choice for busy packing benches, warehouses, workshops, and retail back-of-house environments.
Whether you’re organising components, protecting products from dust and moisture, or preparing items for dispatch, these bags provide a straightforward, professional packaging solution. They’re commonly used anywhere a strong, transparent bag is needed—without the complexity of specialist closures or printed branding.
Key Features
Bottom-weld seal for dependable strength
Bottom-weld bags are sealed across the base, creating a strong foundation that helps support the contents and reduces the risk of splitting at the bottom during normal packing and handling.
Clear film for fast identification
The transparent material allows quick visual checks of contents—useful for picking, packing, stock control, and reducing errors when multiple similar items are being handled.
Heavy-duty gauge for added protection
A thicker polythene film provides improved puncture resistance and durability compared with lighter bags, helping protect items from scuffs, dust, and light moisture during storage and transit.
Paper wrapped supply for neat dispensing
Paper-wrapped packs help keep bags clean and organised, making them easier to store on shelves and simpler to issue to packing stations without loose bags spreading around the work area.
Versatile general-purpose packaging
Suitable for a wide range of non-food applications including parts, textiles, printed materials, and general goods where a strong, clear protective bag is required.

Clear Bottom-Weld Polythene Bags — Full Product Guide
Choosing the right polythene bag is about balancing protection, practicality, and efficiency. Bottom-weld bags are a popular option for general packaging because they’re simple to use, strong at the base, and easy to store. The clear film supports quick identification, while the heavier gauge helps the bag stand up to everyday handling in busy environments.
How It Works
These bags are formed from polythene film and sealed across the bottom edge (the “bottom weld”). This creates a closed base that supports the contents. Items are inserted through the open top, making the bags quick to load and suitable for high-throughput packing tasks. Because the bag is clear, packers can confirm the contents without opening the bag—helpful for quality checks and order accuracy.
Materials and Construction
Polythene film
Polythene (polyethylene) is widely used for protective packaging because it is lightweight, flexible, and resistant to moisture. It provides a practical barrier against dust and light splashes, helping keep products clean during storage and handling.
Bottom-weld seal
The bottom weld is a heat-sealed seam across the base of the bag. This construction is commonly chosen for general-purpose packaging where a dependable base seal is important. The seal helps distribute load across the bottom edge and supports the contents from underneath.
Heavy-duty thickness
A heavier gauge film is typically selected when extra durability is needed—such as when packing items with corners, edges, or a bit more weight. It can also be beneficial when bags are handled repeatedly during internal movements (e.g., from goods-in to storage to packing).
Floor Type Compatibility
These bags are designed for use at packing benches, shelving areas, and dispatch stations rather than as a floor covering. For best results in warehouse environments, store packs in a clean, dry location and dispense bags at workstations to reduce the chance of contamination from floor dust or debris.
Health and Safety
General handling
Use appropriate manual handling practices when packing heavier items. Avoid overfilling the bag beyond what the film and seal can comfortably support.
Choking hazard
Polythene bags can present a suffocation risk. Keep away from babies, children, and vulnerable persons, and store responsibly.
Workplace safety
In busy packing areas, keep unused bags and packaging materials tidy to reduce slip/trip hazards and maintain efficient workflows.
Ideal Applications and Use Cases
Protective inner packaging
Use as an inner bag inside cartons or mailing bags to protect products from dust and light moisture, and to keep multi-part items together.
Organisation and kitting
Ideal for grouping components into kits, separating parts by job number, or organising items by batch. Clear film makes it easy to confirm the correct kit contents.
Presentation and stock control
Clear bags help present items neatly and allow quick stock checks without opening packaging. This can reduce handling time and help maintain product condition.
Maintenance, Cleaning and Care
These bags are intended as a packaging consumable and do not require maintenance. To keep them in best condition before use:
- Store in a dry area away from direct sunlight and heat sources.
- Keep packs sealed or paper wrapped until needed to reduce dust contamination.
- Avoid placing heavy objects on top of packs to prevent creasing or deformation.
Case Study (Typical Workflow Example)
Scenario: A small fulfilment operation ships mixed orders containing hardware, accessories, and printed instructions.
Approach: Items are grouped into clear bottom-weld bags at the picking stage. The clear film allows a quick visual check that the correct parts are included. Bagged items are then placed into cartons with void fill as needed.
Outcome: Faster packing, fewer picking errors, and improved presentation—while keeping small parts contained and protected during transit.
