No20 Pro‑Loc Grip Seal Poly Bags — Full Product Guide
Grip seal bags are a staple packaging format because they combine speed, convenience and reusability. This guide explains what these heavy duty No20 Pro‑Loc bags are best used for, how the closure works, and what to consider when choosing a grip‑seal bag for your application.
How It Works
The grip seal is formed by two interlocking tracks near the bag opening. When you press along the top of the bag, the tracks engage to create a closed seal. To open, you pull the tracks apart at the top edge. This simple mechanism makes grip‑seal bags especially useful where contents may need to be accessed more than once (for example, picking, inspection, sampling, or staged packing).
For best results, close the seal by pressing firmly from one side to the other to ensure the tracks are fully engaged along the full width of the bag opening.
Materials and Construction
These are polythene (poly) grip‑seal bags. The product is described as heavy duty, which indicates a thicker, more robust film intended to better withstand handling and reduce the likelihood of tearing in everyday use.
Where stated by supplier listings for this item, the film is specified as 75 micron / 300 gauge and may include 30% recycled content. Always refer to the specifications shown on this page for the exact variant you are purchasing.
Size and Fit Guidance
This product is commonly referenced as (5 x 8) and listed as 127 x 203mm. When selecting a grip‑seal bag, allow enough room for the contents to sit comfortably below the seal line so the closure can be fully engaged without strain. If you are packing items with sharp corners or edges, consider additional clearance or protective wrapping to reduce puncture risk.
Because configurable product pages can cover multiple options, avoid choosing solely by the name. Check the dimensions shown in the variant details and confirm they match your requirement.
Floor Type Compatibility
Not applicable — this is a packaging product rather than a flooring material.
Health and Safety
As with all plastic bags, keep away from babies and children to avoid suffocation risk. If used in workplaces, ensure staff follow site safety procedures for handling and disposal. If packing food or medical items, confirm suitability for your specific compliance requirements before use.
Ideal Applications and Use Cases
Warehousing and fulfilment:
Use grip‑seal bags to separate SKUs, protect small items, and keep multi‑line orders organised. Clear film supports quick scanning and visual checks.
Engineering, maintenance and workshops:
Ideal for storing fixings, electrical connectors, small tools, and spare parts. Resealability helps when parts are issued and returned or used over time.
Retail and e‑commerce:
A neat, clear presentation for small products and accessories. The resealable closure can be helpful for customers who want to re‑pack items after opening.
Office and admin:
Useful for keeping small stationery items together or protecting documents and labels from dust and handling marks.
Maintenance, Cleaning and Care
Grip‑seal poly bags are typically used as consumables. Store unused bags in a clean, dry area away from direct heat and sunlight to help maintain film performance. If reusing bags, inspect the seal tracks and film for damage or contamination that could prevent a reliable closure.
Case Study (Example Workflow)
A small parts distributor uses heavy duty grip‑seal bags to kit fasteners and fittings into complete sets. Pickers place the required components into the bag, add a printed label and instruction sheet, then press‑seal the closure. Because the bags are clear, a supervisor can quickly verify contents without opening. If a customer requests a change, the bag can be opened, adjusted and resealed without needing new packaging.
