No16 Pro-Loc Grip Seal Poly Bags — Full Product Guide
Grip seal bags are a staple across warehousing, manufacturing and fulfilment because they combine speed, simplicity and reusability. The No16 Pro-Loc grip seal poly bag is designed to provide a consistent, easy-to-handle bag format that supports efficient packing and organisation. Below is a practical guide to help you choose, use and get the best performance from this style of resealable polythene bag.
How It Works
The grip seal closure is formed as two interlocking tracks near the bag opening. When you press along the seal, the tracks engage to create a closed seam. To open, you pull the tracks apart. This simple mechanism makes grip seal bags ideal for workflows where items are added, removed or checked repeatedly—without needing tape, staples or additional closures.
For best results, close the bag by pressing firmly along the full width of the seal. If the bag is filled close to the seal line, leave a small amount of headspace so the tracks can align and close cleanly.
Materials and Construction
These Pro-Loc bags are produced from clear LDPE (low-density polyethylene). LDPE is widely used for flexible packaging because it offers a good balance of clarity, flexibility and toughness. The film thickness for this product is specified as 45 micron (180 gauge), making it suitable for general-purpose packaging and storage where you want a dependable bag without excessive stiffness.
The bags include 30% recycled content and are described as 100% recyclable (subject to local recycling capabilities for LDPE films). If you are working toward packaging sustainability targets, this combination can help support reduced virgin plastic use while maintaining practical performance.
Visibility and Stock Control Benefits
Clear grip seal bags are particularly useful for stock control and operational efficiency. Because contents are visible, teams can verify items quickly during picking, goods-in checks, quality inspection and returns processing. This can reduce mis-picks and minimise the need to open bags just to confirm what’s inside.
In environments where multiple similar components are handled (for example, fasteners, fittings, electrical connectors or small spares), clear bags help keep lines organised and reduce cross-contamination between parts.
Floor Type Compatibility
Grip seal bags are used across a wide range of settings—from clean packing benches to busy warehouse floors. In dusty or high-traffic areas, keeping the seal tracks free from debris helps maintain a reliable closure. If bags are used near powders, fine dust or loose fibres, consider closing the bag away from the immediate source of contamination and avoid overfilling.
For cold stores or unheated warehouses, LDPE remains flexible in typical working conditions, but as with most plastics, it can feel stiffer at lower temperatures. Allowing bags to acclimatise to the packing area can improve handling comfort.
Health and Safety
As with all plastic bags, keep away from babies and small children to avoid suffocation risk. In workplace settings, ensure bags are stored neatly to prevent slip hazards from loose packaging on floors. If you are packing sharp or pointed items, consider whether additional internal protection is needed to prevent punctures and to protect handlers.
When using grip seal bags for parts storage, it’s good practice to label bags clearly (for example, part number, batch, date, or order reference). This supports traceability and reduces handling time.
Ideal Applications and Use Cases
Warehousing and fulfilment:
Use grip seal bags to group items per order line, protect accessories, or keep small components together inside a larger carton. They are also useful for returns processing—keeping returned items separated and identifiable.
Manufacturing and assembly:
Ideal for kitting components for production runs, line-side replenishment, and storing spare parts. The resealable closure supports repeated access during assembly or inspection.
Retail and e-commerce:
A clean, clear bag helps present items neatly and protects them from dust and handling. They can also be used to keep multi-part products together (for example, accessories, fixings, or instruction leaflets).
Office, education and facilities:
Useful for organising stationery, small tools, cables, and consumables. Clear visibility makes it easy to find what you need quickly.
Maintenance, Cleaning and Care
Grip seal bags are designed for convenience rather than long-term maintenance, but a few simple habits can extend usability when bags are reused:
- Keep the seal tracks clean and free from dust or debris for consistent closure.
- Avoid overfilling—leave space so the seal can close flat and evenly.
- For heavier items, support the bag from underneath when carrying to reduce stress on the seal area.
- Store unused bags in a clean, dry place away from direct heat sources.
Case Study (Typical Workflow Example)
Scenario: A small engineering distributor ships mixed orders containing fasteners, fittings and small spares. Previously, items were taped into bundles or placed loose in cartons, leading to picking errors and time spent searching for parts.
Approach: The team introduced clear grip seal bags for each order line. Pickers place each line into a separate bag, add a small label with the part number and quantity, then place the sealed bags into the shipping carton.
Outcome: Contents are visible for quick verification, parts stay separated, and customers can reseal bags for storage after delivery. The packing bench stays tidier and the team reduces rework caused by mixed components.

Sizes Available
This listing relates to the No16 Pro-Loc grip seal bag format. If you are selecting a grip seal bag size, consider the internal space you need for the product plus a little extra headroom to close the seal comfortably. If you are unsure which size is best for your application, choose based on the maximum item dimensions and whether you need room for labels, paperwork or multiple components.
Need help choosing?
If you’re comparing grip seal bags for parts, samples or fulfilment, consider the item’s shape (flat vs bulky), whether it has sharp edges, and how often the bag will be opened and resealed. A slightly larger bag can improve ease of closure and reduce stress on the seal.
