Grip-Seal Polythene Bags
No3 Pro-Loc Grip Seal Poly Bags — Clear Resealable Polythene Bags for Small Parts
No3 Pro-Loc grip seal poly bags are clear, resealable polythene bags designed for fast, tidy and repeatable packing of small items. The integrated press-to-close grip seal makes it easy to open and close the bag multiple times without additional tape, staples or heat sealing. This makes them a practical choice for stockrooms, workshops, retail counters, fulfilment benches and production lines where speed and consistency matter.
These bags are commonly used to organise and protect small components, samples and accessories. The clear film helps with quick identification of contents, while the secure closure helps reduce spills and mix-ups during handling, storage and transit.
Key Features
Pro-Loc press-to-close seal:
Simple, reliable closure that can be opened and resealed repeatedly—ideal for items that need to be accessed, checked, counted or returned to the bag during picking and packing.
Clear LDPE polythene film:
Transparent material supports fast visual checks and barcode/label scanning without needing to open the bag.
40 micron / 160 gauge thickness:
A practical everyday thickness for general-purpose protection and handling of small parts and light items.

No3 Pro-Loc Grip Seal Poly Bags — Full Product Guide
Grip seal bags are a staple packaging format because they combine protection, visibility and convenience in one simple pack. The No3 Pro-Loc grip seal poly bag is designed for smaller items where you want a compact bag that closes securely and can be reopened without damaging the packaging. This guide explains how they work, what they’re made from, and how to choose and use them effectively in day-to-day operations.
How It Works
The grip seal is formed as two interlocking profiles near the opening of the bag. When pressed together along the top, the profiles lock to create a closed seal. To open, you pull the profiles apart. Because the closure is mechanical rather than adhesive, the bag can be opened and resealed repeatedly—useful for inspection, counting, partial use, or staged packing.
For best results, press firmly along the full width of the seal to ensure complete closure. In busy packing environments, a quick “pinch and slide” motion from one side to the other helps confirm the seal is fully engaged.
Materials and Construction
These bags are made from clear LDPE (low-density polyethylene) polythene. LDPE is widely used for flexible packaging because it offers a good balance of clarity, flexibility and toughness. The film thickness is specified as 40 micron (160 gauge), which is a common general-purpose grade for small parts and light items.
The bags are produced with 30% recycled content. This can help reduce reliance on virgin material while still providing a clean, clear bag suitable for everyday packing and storage tasks.
Choosing the Right Bag Size
When selecting a grip seal bag, consider both the dimensions of the item and how you want it to sit inside the bag. As a rule of thumb:
- Allow extra width so the contents don’t strain the seal area and the bag closes easily.
- Allow extra length so the item sits below the seal and you can close the bag without forcing it.
- Consider bulk and shape—irregular items may need more space than flat items of the same nominal size.
If you are packing multiple pieces (for example, a small kit of fixings), allow additional room so the bag can be shaken flat and sealed without trapping items in the closure.
Floor Type Compatibility
Grip seal poly bags are commonly used across a wide range of environments, including:
- Warehouses and fulfilment centres
- Workshops and engineering stores
- Retail stockrooms and counter areas
- Offices and mailrooms
Because they are lightweight and compact, they store efficiently on shelving, in drawers, or in pick bins. For high-throughput packing benches, keeping bags in a dispenser or open-top bin can improve speed and reduce handling time.
Health and Safety
As with all plastic bags, keep away from babies and small children due to suffocation risk. In workplace settings, ensure loose bags are stored neatly to reduce slip/trip hazards and prevent them from being drawn into machinery or ventilation intakes.
If you are packing sharp-edged components, consider whether the item could puncture the film during handling. For particularly sharp or heavy parts, a thicker gauge or alternative protective packaging may be more suitable.
Ideal Applications and Use Cases
Stock control and organisation:
Use grip seal bags to separate and label small components, reducing picking errors and keeping bins tidy. Clear film makes it easy to confirm contents at a glance.
Kitting and assembly:
Ideal for preparing small kits of parts for production lines or service teams. The resealable closure supports staged workflows—items can be checked and resealed without replacing the bag.
Retail presentation:
Suitable for small accessories and spares where a clean, clear bag improves presentation and protects items from dust and handling.
Returns and repairs:
Useful for re-bagging returned items, keeping components together, and preventing loss of small parts during inspection.
Maintenance, Cleaning and Care
Grip seal poly bags are designed for convenience and general-purpose protection. To keep packing operations efficient:
- Store bags in a clean, dry area away from direct heat sources.
- Avoid overfilling—this helps the seal close properly and reduces stress on the film.
- When applying labels, place them on a flat area of the bag to maintain readability and adhesion.
For environments where contamination control is critical, ensure your internal procedures specify whether bags are single-use or can be reused for the same item type.
Case Study (Typical Workflow Example)
A maintenance department keeps a wide range of small electrical connectors and fixings. Previously, parts were stored loose in shared bins, leading to mixed stock and time-consuming recounts. By switching to labelled grip seal bags, each connector type is separated and clearly identified. Technicians can take a bag to a job, open and reseal it as needed, and return unused parts without mixing stock. The result is faster picking, fewer errors, and improved stock accuracy.
Who Is It For?
