Grip-Seal Polythene Bags
Overview
No2 Pro-Loc grip seal poly bags are clear, resealable polythene bags designed for fast packing, tidy presentation and reliable closure. The integrated press-to-close seal makes them ideal for organising small parts, protecting items from dust and handling, and keeping components grouped together during storage, picking and dispatch. This listing covers the No2 size (approx. 2.25 x 3 in / 57 x 76 mm) in the Pro-Loc range.

No2 Pro-Loc Grip Seal Poly Bags — Full Product Guide
Grip seal bags are a staple packaging and organisation solution because they combine speed, convenience and a neat finish. The No2 Pro-Loc bags are designed for smaller items where you want a compact bag that still opens easily and closes securely. Below is a practical guide to help you choose the right option and get the best performance from your bags.
How it works
The grip seal (also called a press-to-close or zip-style seal) is formed as two interlocking tracks near the top of the bag. When you press along the seal, the tracks engage to create a closed line across the opening. To open, you pull the tracks apart. This simple mechanism makes the bags suitable for repeated access—useful when items are picked, counted, checked or returned to storage.
Because the closure is integrated into the bag, you don’t need separate fasteners. That can reduce packing time and helps keep work areas tidy, especially when you’re handling many small parts.
Materials and construction
These bags are made from clear LDPE (low-density polyethylene) polythene. LDPE is widely used for flexible packaging because it is lightweight, flexible and offers good clarity for viewing contents. The film thickness for this product is 40 micron (160 gauge), providing a practical balance between flexibility and everyday protection.
This Pro-Loc bag is produced with 30% recycled content. Using recycled content can help reduce reliance on virgin plastic while still delivering a functional, clear bag for routine packaging and organisation tasks.
Size and capacity guidance
This listing is the No2 size, approximately 2.25 x 3 inches (57 x 76 mm). This compact format is commonly chosen for small, lightweight items. If you are unsure which size you need, a simple approach is to measure the longest dimension of your item and allow extra space for easy insertion and for the seal area at the top.
- For flat items: allow a little extra width so the item slides in without catching.
- For multiple small parts: consider the combined bulk—if the bag becomes too full, sealing can be harder and the contents may stress the film.
- For sharp edges: consider whether a thicker bag or additional inner protection is needed.
Closure performance and everyday handling
Grip seal bags are designed for convenience. For best results, press firmly along the full length of the seal to ensure it is fully engaged. If you are packing in a busy environment, it can help to run a finger and thumb across the seal once more as a quick check.
Because the bags are clear, they support quick visual checks—useful for quality control, kitting, and ensuring the right parts are included before dispatch.
Floor type compatibility
Not applicable—this is a packaging product rather than a flooring product. If you are using these bags in industrial environments, consider how they will be stored and dispensed (for example, in bins, drawers, or on packing benches) to keep them clean and easy to access.
Health and safety
As with many plastic bags, keep away from babies and young children due to suffocation risk. In workplaces, ensure bags are used appropriately for the items being packed and that any sharp components are handled safely. If you are packing food or medical items, confirm suitability for your specific compliance requirements before use.
Ideal applications and use cases
The No2 Pro-Loc grip seal bag is particularly useful where small items need to be kept together and accessed repeatedly:
- Engineering and maintenance: organising fixings, seals, clips and small spares.
- Electrical and electronics: keeping connectors, terminals and small components separated.
- Retail and e-commerce: presenting small accessories neatly and protecting them in transit.
- Workshops and tool control: creating small kits for jobs or service calls.
- Craft and hobby: sorting beads, findings, model parts and other small pieces.
Maintenance, cleaning and care
Grip seal bags are typically used as consumables, but they can be reused for non-critical applications if they remain clean and undamaged. Store unused bags in a clean, dry area away from direct sunlight and excessive heat to help maintain film performance and clarity.
- Avoid overfilling, which can strain the seal and film.
- Keep the seal area free from dust or debris for best closure.
- If bags are used for parts with oils or residues, consider whether reuse is appropriate.
Case study (example workflow)
Scenario: A small assembly operation needs to kit fasteners and fittings for multiple product variants. Previously, parts were stored loose in bins, leading to picking errors and time spent recounting.
Approach: The team pre-kits each set of small components into No2 grip seal bags, labels the bag with the kit code, and stores kits in order of production schedule.
Result: Faster picking and fewer errors because each kit is visually identifiable and remains sealed until use. The resealable closure allows quick checks without needing to replace packaging each time.
