Grip-Seal Polythene Bags
No14 Pro-Loc Grip Seal Poly Bags — Resealable Protection for Storage, Packing & Dispatch
No14 Pro-Loc grip seal poly bags are clear, resealable polythene bags designed to make packing, organising and protecting items quick and repeatable. Each bag features an integrated press-to-close grip seal that allows you to open and reseal the bag multiple times without additional tape or ties. This makes them a practical choice for workplaces that need fast picking and packing, as well as for storage where contents may need to be accessed regularly.
These bags are commonly used anywhere you want a clean, lightweight barrier against dust and handling marks, while still keeping contents visible for easy identification. They are supplied as grip-seal polythene bags and are part of Sapphire’s resealable (grip seal) bag range.

No14 Pro-Loc Grip Seal Poly Bags — Full Product Guide
Grip seal bags are a staple packaging format because they combine speed, visibility and reusability in one simple product. The No14 Pro-Loc grip seal poly bag format is designed for users who want a dependable reseal and a clear presentation for stored or shipped items. 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 is formed as an integrated closure near the opening of the bag. To close, align the seal tracks and press along the top to engage the seal. To open, pull the tracks apart. This closure method is designed for repeated use, making it ideal for workflows where items are accessed multiple times (for example, picking, inspection, or staged assembly).
For best results, close the seal by pressing from one side to the other to ensure the full length is engaged. If the bag is used in dusty environments, keeping the seal area clean helps maintain consistent closure performance.
Materials and Construction
These are polythene (poly) grip seal bags. Polythene film is widely used in packaging because it is lightweight, flexible and provides a practical barrier against dust and handling. The clear film supports quick identification of contents and helps reduce packing errors.
Grip seal bags are typically manufactured with a welded seam construction and an integrated seal profile. This combination supports everyday packing and storage tasks where a neat, professional presentation is required.
Choosing the Right Bag Size (Practical Fit Guidance)
When selecting a grip seal bag, consider not only the length and width of the item, but also its thickness and how you want it to sit inside the bag. As a rule of thumb:
- Allow extra width for bulky or irregular items so the bag can close without strain.
- Allow extra length so the seal can close comfortably above the contents.
- If you are packing multiple items together (kitting), consider the combined thickness and whether items need to lie flat.
If you are standardising packaging across a team, it can be helpful to trial a small quantity first to confirm fit and closure comfort for your specific products.
Compatibility With Labels, Inserts and Documentation
Clear grip seal bags are commonly used with labels and inserts because the contents remain visible and the bag can be reopened without damage. Typical approaches include:
- Placing paperwork (instructions, delivery notes, certificates) inside the bag with the product.
- Applying labels to the outside for barcoding, batch identification or routing.
- Using the bag as an inner pack inside cartons, mailers or larger polybags.
Where barcode scanning is required, keeping the label flat and free from creases improves scan reliability.
Health and Safety
As with all plastic bags, keep away from babies and children to avoid suffocation risk. In workplace settings, store bags in a clean, dry area and keep them away from heat sources. If you are packing sharp-edged items, consider whether additional protection is needed to prevent punctures.
Ideal Applications and Use Cases
These resealable poly bags are widely used across many sectors because they are quick to use and easy to standardise. Common use cases include:
- Warehousing & fulfilment: separating SKUs, packing accessories with main products, and organising returns.
- Manufacturing & assembly: kitting components, protecting parts between process steps, and storing spares.
- Retail & eCommerce: presenting items neatly, protecting products in transit, and keeping sets together.
- Offices & facilities: organising stationery, cables, fixings and small maintenance items.
Maintenance, Cleaning and Care
Grip seal poly bags are typically used as a consumable packaging item. However, for internal storage applications they may be reused where appropriate. To support reuse:
- Keep the seal area free from dust and debris.
- Avoid overfilling, which can stress seams and the seal profile.
- Store unused bags flat in their original packaging to reduce creasing.
Case Study (Typical Workflow Example)
Scenario: A small assembly operation needs to kit multiple components per order and reduce picking errors.
Approach: Each order is picked into a resealable grip seal bag along with a printed checklist. The clear film allows supervisors to verify contents at a glance without opening the bag. If a component needs to be swapped during QC, the bag can be reopened and resealed quickly.
Outcome: Faster packing, clearer presentation, and fewer instances of mixed parts—without adding extra tape or secondary closures.
Who Is It For?
- Businesses that need a fast, repeatable packing method
- Teams that want to keep items visible while protected
- Operations that require resealable packaging for inspection, kitting or returns
