These No11 Pro-Loc grip seal poly bags are a practical, everyday resealable packaging option for organising, protecting and presenting small to medium items.

No11 Pro-Loc Grip Seal Poly Bags — Full Product Guide
Grip seal bags are a staple packaging choice because they combine simplicity with repeat usability. This guide explains how these No11 Pro-Loc grip seal poly bags are typically used, what to consider when choosing a resealable bag, and how to get the best results in storage and packing workflows.
How It Works
The bag is opened by separating the two sides of the grip seal at the top. Once contents are inserted, you close the bag by pressing along the seal from one side to the other to ensure a consistent closure. This creates a simple, reusable seal that helps keep items contained and reduces the chance of parts being lost during handling.
For best results, avoid overfilling the bag near the closure area. Leaving a small amount of space at the top makes it easier to close the seal fully and helps maintain a neat, flat pack.
Materials and Construction
These bags are made from polythene (poly) film and are designed to be clear for visibility. Polythene is widely used in packaging because it is lightweight, flexible and suitable for everyday protection and organisation tasks.
Because grip seal bags are intended for repeated opening and closing, the closure area is designed to be easy to align and press shut. In busy environments such as packing benches or stores, this can be a time-saving alternative to single-use bags that require tape or additional sealing steps.
Size and Fit Guidance
This product is listed as No11 size and described as 6 x 9 (152 x 229mm), often referred to as “A5 size”. When selecting a grip seal bag, consider not only the flat dimensions but also the thickness and shape of the item you are packing. Bulky items may require additional space to allow the seal to close comfortably.
If you are packing paper items, consider whether you want a close fit for a tidy presentation or extra room for inserts, folded documents or multiple sheets.
Floor Type Compatibility
Not applicable — this is a packaging product rather than a flooring product.
Health and Safety
As with many plastic packaging items, keep bags away from babies and young children to avoid suffocation risk. In workplace settings, ensure loose packaging is stored tidily to reduce slip/trip hazards and to keep packing areas organised.
If you are using grip seal bags for parts or samples, consider adding a label or insert to help prevent mix-ups, especially where similar-looking components are stored together.
Ideal Applications and Use Cases
eCommerce and fulfilment
Use grip seal bags to group accessories, spare parts, small items or paperwork within a larger shipment. This helps keep orders organised and can improve the unboxing experience by presenting items neatly.
Workshops and maintenance
Ideal for sorting fixings, connectors and small components. The clear film makes it easy to identify contents without opening, which can reduce time spent searching for parts.
Office and administration
Useful for storing small stationery items, labels, spare keys, cables or paperwork inserts. The resealable closure supports repeated access without needing staples or tape.
Education and craft
A practical option for organising craft materials, small tools, beads, fasteners and project components, keeping sets together between sessions.
Maintenance, Cleaning and Care
Grip seal poly bags are typically used as disposable packaging, but they can also be reused for organisation where appropriate. If reusing, keep the closure area free from dust and debris so the seal can press together cleanly. Store unused bags in a clean, dry place to keep them ready for packing.
Case Study (Example Workflow)
A small parts distributor uses No11 grip seal bags to pre-pack common fastener kits. Each kit is counted, bagged and labelled, then stored in bins. When an order is picked, the packer can visually confirm the contents through the clear film, reducing errors and speeding up dispatch. The resealable closure also allows quick checks or adjustments without needing to replace the bag.
Who is it for?
