120G Lay Flat Tubing (LFT)
15" Lay Flat Tubing (381mm) — 120G (30µ) Polythene Tubing
Lay flat tubing is a versatile polythene tube supplied flattened on a roll, designed to let you create protective sleeves and bags to suit the length of your product. This listing is for lay flat tubing with a lay-flat width of 15" (381mm) and a film thickness of 30 microns (30µ), commonly referenced on this product range as 120G. It’s a practical choice when you need flexible, lightweight protection for parts, components, and goods in storage or transit, and when pre-made bag lengths aren’t ideal.
Because lay flat tubing is supplied as continuous tubing, you can cut it to the length you need and seal the ends to create a custom-sized bag or sleeve. This helps reduce waste and can simplify packing workflows where product lengths vary.
Key Features
Made-to-length packaging: Cut the tubing to your required length to create sleeves or bags for different product sizes without stocking multiple bag lengths.
15" (381mm) lay-flat width: The lay-flat measurement is taken across the tubing when flattened, helping you match the tubing to the width of your item.
30µ (micron) film thickness: A light-to-medium gauge film that provides everyday protection against dust and scuffs while keeping packaging weight low.
Continuous roll format: Ideal for bench packing, production lines, and dispatch areas—use with a dispenser and cut/seal as needed.
Polythene protection: Helps keep items clean and separated during handling, storage, and distribution.

- Format: lay flat tubing on a roll
- Use: cut and seal to suit your application
Typical Uses
- Protecting long or irregular items where standard bag lengths are inconvenient
- Creating sleeves for parts, components, and assemblies
- Keeping products clean in storage (dust and handling protection)
- Separating items in cartons to reduce scuffing
- General packing and dispatch operations
15" Lay Flat Tubing (381mm) — Full Product Guide
Lay flat tubing is widely used across packing, warehousing, and manufacturing because it offers a simple way to create packaging that fits. Instead of choosing from many pre-made bag lengths, you select the tubing width and film thickness that suit your product, then make the length you need on demand.
How It Works
Lay flat tubing arrives as a continuous tube of polythene that has been flattened and wound onto a roll. To use it:
- Pull out the required length of tubing.
- Cut the tubing to size.
- Seal one end (if you’re making a bag), insert the product, then seal the other end.
Depending on your process, sealing can be done with a heat sealer. For sleeve-style protection, you may only need to seal one end or leave ends open where appropriate.
Materials and Construction
This product is polythene lay flat tubing. Polythene film is commonly chosen for protective packaging because it is lightweight, flexible, and easy to handle. The thickness on this listing is 30µ, which is often used for general-purpose protection where you want a balance between flexibility and durability.
The product title also references 120G for this range. Where “G” is used as a gauge reference, it is typically used as a quick way to identify film thickness within a product family.
Understanding Lay-Flat Width
The stated width (15" / 381mm) is the lay-flat width, measured across the tubing while it is flattened. When the tube is opened, the circumference is approximately double the lay-flat width. In practice, you should allow clearance for the shape of your product and any sharp corners or protrusions.
If you are packaging boxed items or products with edges, consider allowing extra width so the film is not overstressed during insertion.
Floor Type Compatibility
Lay flat tubing is used in a wide range of environments—from packing benches to warehouse dispatch areas. It can be used with:
- Bench-top packing stations
- Roll dispensers and cutters
- Heat sealing equipment (where sealed bags are required)
Because it is supplied on a roll, it’s easy to integrate into existing packing workflows without needing specialist machinery.
Health and Safety
- Cutting: Use appropriate cutting tools and safe handling practices when trimming film from the roll.
- Heat sealing: If using a heat sealer, follow the equipment manufacturer’s guidance and allow sealing bars to cool before contact.
- Slip/trip: Keep offcuts tidy—thin film can be slippery underfoot.
- Storage: Store rolls in a clean, dry area away from excessive heat and direct sunlight.
Ideal Applications and Use Cases
This 15" (381mm) lay flat tubing is commonly selected when you need a mid-width sleeve/bag format for products that vary in length. Typical use cases include:
- Manufacturing and assembly lines packing parts at the end of a process
- Warehousing operations creating protective sleeves for stock items
- Dispatch teams packing mixed orders where lengths vary
- Protective wrapping for items that need to stay clean and separated
Maintenance, Cleaning and Care
- Keep the roll clean: Dust and debris can transfer to packed goods—store rolls in their packaging until use.
- Use a dispenser: A roll dispenser helps prevent the film from dragging on the floor and reduces handling damage.
- Check sealing settings: If you seal the tubing, adjust temperature/time to suit the film thickness for consistent seals.
Case Study (Typical Workflow Example)
A small dispatch area handling mixed-length components can keep one roll of lay flat tubing at a packing bench. Staff pull out the required length, cut, seal one end, insert the item, then seal the other end. This approach reduces the need to stock multiple bag lengths and helps standardise packing for varied products.
Who is it for?
- Warehouses and fulfilment teams needing flexible, on-demand bag lengths
- Manufacturers packing parts and assemblies with variable dimensions
- Workshops and maintenance teams protecting items during storage
- Businesses looking to reduce the number of different bag SKUs they hold
Colours / Features Available
