5x7 Clear Poly Bags (100g / 25 micron) — Full Product Guide
Clear poly bags are one of the most widely used packaging formats because they solve a simple problem extremely well: keeping items together and protected while remaining visible. This guide explains what these bags are best suited for, how to choose the right option, and how to get the best results in day-to-day packing.
How It Works
A poly bag is a flat, flexible plastic bag made from polythene film. You place the item inside, then close the opening using your preferred method (for example, folding, taping, or using a separate label/seal depending on your process). The clear film allows the contents to be seen without opening the bag, which can speed up picking, checking and presentation.
Because the bag is lightweight and supplied flat, it’s quick to handle at a packing bench. Many businesses keep multiple sizes on hand so packers can choose the closest fit for each product, reducing wasted space and improving the finished look.
Materials and Construction
These bags are made from clear polythene film in a lightweight grade (listed as 100g / 25 micron). Polythene is valued in packaging because it is flexible, resistant to tearing in normal handling, and provides a simple barrier against dust and light surface moisture. The film is transparent, helping maintain product visibility for retail presentation and internal stock control.
Lightweight poly bags are typically chosen for items that don’t have sharp edges and don’t require heavy-duty puncture resistance. If you are packing heavier items, sharp components, or products that will be handled repeatedly in transit, you may prefer a thicker grade—however, for everyday packing and organisation, lightweight film is often the most economical and efficient choice.
Size and Fit (Choosing the Right Option)
This listing represents a 5x7 format (approx. 127 x 178mm). When selecting a bag size, aim for a fit that allows the product to slide in easily without forcing, while avoiding excessive empty space. A closer fit generally looks more professional and can reduce movement inside the bag.
If your product includes multiple parts (for example, an item plus instructions or accessories), consider the combined thickness and whether you need extra room for easy packing. For flat items such as printed materials, a snug fit helps keep corners neat and reduces creasing.
Floor Type Compatibility
Not applicable—this is a packaging consumable rather than a flooring product. If you are using these bags in a warehouse or production environment, they are well suited to packing benches, shelving, and standard fulfilment workflows.
Health and Safety
As with all plastic bags, keep away from babies and young children due to suffocation risk. In a workplace setting, ensure loose packaging materials are stored tidily to reduce slip/trip hazards and to keep packing areas organised. If you are packing food or medical items, confirm suitability for your specific compliance requirements and intended use before purchase.
Ideal Applications and Use Cases
Retail presentation:
Use clear bags to keep products clean and presentable on shelves, hooks, or in bins while still allowing customers to see the item.
E-commerce fulfilment:
Ideal for separating items within an order, protecting accessories, or keeping paperwork with the product. Clear visibility can reduce packing errors.
Workshops and engineering stores:
Useful for sorting small parts, fixings, and components—especially when paired with labels for quick identification.
Office and education:
Great for organising stationery, handouts, and small supplies. Transparent film makes it easy to find what you need.
Maintenance, Cleaning and Care
Poly bags are designed for convenience and are typically used as a single-use or short-term protective layer, depending on your application. Store unused bags in a clean, dry area away from direct heat and sunlight to help maintain film clarity and performance. If reusing bags for internal organisation, inspect for tears or punctures and replace as needed.
Case Study (Example Workflow)
Small parts packing for dispatch:
A parts supplier uses clear 5x7 poly bags to separate different fasteners and fittings within each customer order. Each bag is labelled with the SKU and quantity, then grouped into an outer shipping carton. The clear film allows a quick visual check during packing and reduces mis-picks, while the lightweight material keeps packaging costs controlled.
