No13 Pro-Loc Grip Seal Poly Bags — Full Product Guide
Grip seal bags (also known as resealable polythene bags) are a staple packaging solution because they combine speed, simplicity and reusability. The No13 size provides a generous square format that works well for larger flat items, grouped components, or products that benefit from a neat, protective outer bag. Use this guide to choose the right option and get the best performance from your bags.
How It Works
The grip seal closure is formed as an interlocking track near the opening of the bag. By pressing along the seal, the tracks engage to close the bag. To open, simply pull the tracks apart. This makes the bag suitable for tasks where contents need to be accessed multiple times—without the need for tape, staples or heat sealing.
For best results, close the seal by pressing firmly from one side to the other to ensure the track is fully engaged along the full width.
Materials and Construction
These bags are made from polythene (poly) film and supplied in a clear finish to support quick identification of contents. Polythene is widely used in packaging because it is lightweight, flexible and resistant to tearing under normal handling. The grip seal track is integrated into the bag opening to provide a consistent reseal.
Because this is a configurable product page, specifications such as pack quantity are selected via the variant options shown on the page.
Size and Fit Guidance
This listing is for the No13 size, shown as approximately 12.75" x 12.75" (324 x 324mm). When choosing a grip seal bag size, allow extra space for the thickness/bulk of the contents and for comfortable sealing at the top. If you are packing multiple items together, consider how they will sit in the bag (stacked vs. laid flat) and whether you need room for a label or paperwork.
Floor Type Compatibility

Health and Safety
- Keep polythene bags away from babies and small children due to suffocation risk.
- Use appropriate handling procedures in workplaces where small parts are packed (e.g., avoid loose items creating slip hazards).
- If using for industrial components, ensure any sharp edges are suitably protected to reduce puncture risk.
Ideal Applications and Use Cases
Warehousing & fulfilment:
Use grip seal bags to separate order lines, protect accessories, and keep small items from getting lost in cartons.
Manufacturing & assembly:
Ideal for kitting parts per build, batching fixings, or staging components between workstations.
Retail & e-commerce:
Useful for bundling products, protecting items from handling, and presenting accessories neatly.
Offices & facilities:
Store stationery, cables, keys, badges, and documents that need to stay clean and together.
Maintenance, Cleaning and Care
- Store bags in a clean, dry area away from direct heat sources.
- Keep the grip seal track free from dust and debris for best resealing performance.
- For reuse, empty the bag fully and wipe lightly if needed; replace bags that become torn or heavily creased at the seal.
Case Study (Typical Workflow Example)
A small assembly operation uses No13 grip seal bags to kit components for each job. Each bag is labelled with the job number and contains all required fixings and accessories. The clear film allows quick visual checks before the kit moves to the next workstation. Because the bags reseal, operators can open them to remove parts and reseal the remainder, reducing mix-ups and keeping benches tidy.
