Grip-Seal Polythene Bags
No10 Pro-Loc Grip Seal Poly Bags (Approx. 191 x 191mm / 7.5 x 7.5in) — Clear Resealable Polythene Bags
Pro-Loc grip seal poly bags are a practical, everyday packaging solution for organising, protecting and presenting items. The No10 size (often referenced as approximately 7.5 x 7.5 inches / 191 x 191mm) offers a generous square format that suits a wide range of products, parts and materials. Each bag features an easy-to-use press-to-close grip seal that allows the contents to be accessed and resealed repeatedly, helping to keep items clean, contained and easy to identify.
These resealable polythene bags are commonly used across retail, eCommerce fulfilment, workshops, warehouses, offices, schools and at home. They are especially useful when you need a lightweight, space-efficient way to separate items, reduce mix-ups, and provide a simple barrier against dust and handling.

No10 Pro-Loc Grip Seal Poly Bags — Full Product Guide
Grip seal bags (also called resealable or zip-style polythene bags) are designed to make packing and storage simpler. The Pro-Loc style closure provides a straightforward press-to-seal action that is quick to use and easy to check. This guide explains how these bags work, where they fit best, and how to get the most from them in real-world packing and storage situations.
How It Works
The grip seal is formed by two interlocking tracks near the opening of the bag. When you press along the top edge, the tracks engage to create a closed seal. To open, you pull the tracks apart. This design supports repeated access to the contents while keeping items contained between uses.
For best results, close the seal by pressing firmly along the full width of the opening. In busy packing environments, a quick visual and fingertip check along the seal line helps confirm it is fully engaged.
Materials and Construction
These bags are made from polythene (polyethylene) film, a widely used packaging material valued for its flexibility, low weight and practical protective qualities. The film is clear to support easy identification of contents and to help reduce handling time when sorting or picking.
The bag construction is designed for general-purpose packaging and storage. While grip seal bags provide a convenient closure, they are typically used for containment and organisation rather than as a tamper-evident or high-security seal.
Storage and Handling Benefits
Grip seal poly bags are a simple way to improve organisation and reduce product damage or loss. By keeping items grouped and enclosed, they can help prevent small components from scattering, reduce surface scuffs from handling, and keep dust away from sensitive items.
Because the bags are lightweight and flexible, they store efficiently and can be kept close to the packing bench or workstation. This makes them a popular choice for operations that need quick access to packaging without taking up much space.
Choosing the Right Size (Why No10 Works Well)
The No10 size is commonly listed as approximately 191 x 191mm (7.5 x 7.5 inches). This square format is useful when you want a balanced shape that can accommodate a variety of items without forcing them into a narrow profile. It can be particularly handy for sets of components, accessories, or items that are wider than they are long.
If you are unsure which size you need, consider the maximum width and height of your item and allow extra room for easy loading and comfortable sealing at the top. If you are packing multiple items together, allow additional space so the seal can close without strain.
Ideal Applications and Use Cases
Retail and eCommerce fulfilment
Use grip seal bags to bundle accessories, protect items inside shipping cartons, or keep multi-part products together. They can also help keep paperwork, labels or small add-ons with the correct order.
Workshops, trade counters and maintenance teams
Great for organising fixings, fittings and spare parts. They help reduce time spent searching for components and can support job-based organisation (for example, keeping all parts for a specific task together).
Warehousing and stock control
Clear bags make it easier to identify contents quickly. They can be used to separate stock by type, batch or location, and to keep small items contained during picking and replenishment.
Offices, schools and studios
Useful for stationery, craft materials, samples and general organisation. The resealable closure makes them convenient for items that are accessed repeatedly.
Health and Safety
As with many plastic packaging products, keep bags away from babies and young children to avoid suffocation risk. In workplace settings, ensure packaging is used appropriately for the task and that any items with sharp edges are packed in a way that reduces puncture risk.
If you are using bags for food contact, medical use, or regulated applications, confirm suitability for your specific requirements before use.
Maintenance, Cleaning and Care
Grip seal poly bags are typically intended for single-use packaging or short-term reuse depending on the application. If reusing, ensure the bag is clean and dry, and check that the seal tracks are free from dust or debris so the closure engages properly.
Store unused bags in a clean, dry area away from direct sunlight and excessive heat to help maintain film performance and clarity.
Case Study (Example Workflow)
Scenario: A small eCommerce seller ships products that include multiple accessories and printed instructions.
Challenge: Accessories can become separated in the carton, and paperwork can crease or get misplaced.
Approach: The seller places accessories and instructions into a grip seal bag before packing into the shipping box.
Result: Faster packing, fewer missing-item queries, and a cleaner unboxing experience because all components arrive together and protected.
