No12 Pro-Loc Grip Seal Poly Bags — Full Product Guide
Grip seal bags are a staple for businesses that need a quick, tidy, and professional way to pack items that may be accessed more than once. This No12 Pro-Loc bag size is widely used across trade counters, fulfilment operations, and production environments because it balances capacity with easy handling. The clear LDPE film supports fast picking and checking, while the resealable closure helps keep contents together from packing through to storage or dispatch.
How It Works
The Pro-Loc closure is designed to be simple: align the top edges and press along the seal to close. To reopen, pull the top edges apart. This open/close cycle can be repeated as needed, making these bags ideal for items that are checked, counted, or partially used over time. For best results, press firmly along the full width of the seal to ensure consistent closure.
Materials and Construction
These bags are produced from clear LDPE (low-density polyethylene) polythene, a flexible plastic film commonly used for packaging due to its clarity and toughness. The film specification is listed as 45 micron / 180 gauge, providing a dependable everyday thickness for general packing and protection. The material includes 30% recycled content, supporting reduced virgin plastic use while maintaining practical performance for routine applications.
Visibility and Presentation
Because the film is clear, contents can be identified quickly without opening the bag. This helps reduce handling time in busy environments such as picking/packing benches, stores, and workshops. Clear bags also support neat presentation for retail accessories, kits, and spares, and can help reduce errors when multiple similar items are stored together.
Protection and Organisation
Grip seal bags are commonly used to keep items grouped and protected from dust, light splashes, and general handling. They are particularly useful for preventing small components from being misplaced and for keeping sets complete (for example, a product plus its fittings, instructions, or spare parts). While they provide practical day-to-day protection, they are not intended as a specialist barrier pack for high-risk moisture-sensitive goods unless additional protective measures are used.
Floor Type Compatibility
These bags are suitable for use across typical working environments including warehouses, packing stations, offices, and retail backrooms. They can be used at benches, on shelving, and in storage bins. If used in production areas, consider standard site practices for cleanliness and contamination control.
Health and Safety
As with all plastic bags, keep away from babies and children to avoid suffocation risk. In workplace settings, ensure bags are stored neatly to prevent slips or snagging hazards. If you are packing sharp or pointed items, consider whether additional protection (such as wrapping the item first) is required to reduce puncture risk.
Ideal Applications and Use Cases
Warehousing & fulfilment: Use for picking small items, consolidating accessories, and keeping order lines separated.
Manufacturing & assembly: Ideal for kitting components, storing sub-assemblies, and keeping parts clean between process steps.
Trade counters & workshops: Handy for screws, bolts, washers, electrical connectors, and general fixings.
Office & admin: Useful for organising documents, labels, and small stationery items that need to stay together.
Retail: Suitable for packaging small products, spares, and accessories where visibility matters.
Maintenance, Cleaning and Care
Grip seal bags are designed for convenience and repeat use during normal handling. To keep them performing well, avoid overfilling and keep the seal area free from dust or debris so it can close properly. If the bag becomes heavily creased, contaminated, or damaged, replace it to maintain a tidy and secure pack.
Case Study (Typical Workflow Example)
A small parts distributor uses No12 grip seal bags to create ready-to-ship kits: each kit includes the main component plus fittings and an instruction sheet. The clear bag allows staff to verify contents at a glance, while the resealable closure makes it easy to add last-minute items or paperwork without re-packing. This reduces packing time and helps prevent missing parts, improving consistency across orders.
