500G Lay Flat Tubing (LFT)
Lay Flat Tubing (LFT) — flexible polythene packaging on a roll
Lay flat tubing is a continuous tube of polythene supplied wound on a roll. Because it is sealed along both edges and open at the ends, you can cut it to the length you need, insert your product, and then seal the open end to create a custom-length bag on demand. This makes LFT a practical choice when you pack items of varying lengths, when you want to reduce the number of bag sizes you keep in stock, or when you need a fast, repeatable way to protect goods from dust and handling during storage and transit.
This listing is for 500G (127µm) lay flat tubing. “500G” is commonly used in packaging to indicate a heavier-duty film, and 127 micron (µm) is the thickness value shown in the product title. Lay flat tubing is often selected where a stronger film is preferred for general industrial packing, parts protection, and bundling.
Key Features
Made to length (cut-and-seal convenience)
Create bags at the exact length you need. Cut the tubing from the roll, load the item, then seal to form a neat, enclosed pack. This approach is ideal when product lengths vary or when you want to minimise wasted material compared with using oversized pre-made bags.
Continuous tube format for efficient packing
Because the material is supplied as a continuous tube, you can run repeat packing operations quickly—especially when paired with a suitable heat sealer. It also helps streamline storage because one roll can cover many “bag lengths”.
500G / 127µm film for robust protection
The specified thickness (127µm) indicates a heavier film designed for more demanding packing tasks than lighter gauges. It is commonly chosen for protecting items from scuffs, dust, and general handling during internal movement, warehousing, and distribution.
Versatile for irregular and long items
Lay flat tubing is particularly useful for long, awkward, or irregularly shaped products that are difficult to fit into standard bag sizes. You can simply cut longer lengths as required.
Neat presentation and easy identification
A clean, sealed pack helps keep products tidy and contained. Depending on your packing process, you can also add labels to the outside of the finished bag for identification and traceability.
- Cut-to-length packaging from a single roll
- 127µm (500G) film thickness as stated in the product title
- Layflat width shown in the product title (width measured when the tube is laid flat)
- Suitable for heat sealing to create custom bags
- Good for long or variable-length items where standard bags are inefficient
Typical Uses
- Protecting components, parts, and assemblies from dust and handling marks
- Bundling multiple items together into one sealed pack
- Packaging long products where pre-made bags are impractical
- Creating custom-length inner packs for cartons, crates, or pallets
- General warehouse and despatch packing where flexibility is important
Lay Flat Tubing — Full Product Guide
Introduction
Lay flat tubing is designed to give you the flexibility of “made-to-measure” bags without needing bespoke manufacturing for every length. Instead of choosing from many fixed-size bags, you select the tubing width that suits your product and then cut the length as needed. This can simplify purchasing, reduce storage space for packaging, and help standardise packing processes across different product lines.
How It Works
1) Choose the correct layflat width
Layflat width is the measurement across the tube when it is flattened. When opened, the tube forms a circumference approximately double the layflat width. Selecting the right width helps ensure your product fits comfortably without excessive slack.
2) Cut to length
Measure and cut the tubing to the length required for your item, allowing extra length for sealing at one or both ends depending on your process.
3) Seal the end(s)
Use a suitable heat sealer to close one end (if not already sealed), insert the product, then seal the remaining open end. This creates a finished bag tailored to your product length.
4) Label and despatch
Apply labels as needed for identification, batch control, or shipping information. The finished pack can then be placed into outer cartons or shipped as required.
Materials and Construction
This product is supplied as polythene lay flat tubing (as indicated by the product type on the page). Polythene film is widely used in packaging because it is lightweight, flexible, and provides a practical barrier against dust and moisture in typical storage and handling environments. The tubing format means the film is sealed along both sides, forming a continuous tube on a roll.
Thickness (as listed): 127µm
Film thickness is a key factor in performance. A thicker film generally offers improved puncture resistance and durability for tougher packing tasks. This listing specifies 127 micron in the title, which is commonly associated with 500G in packaging terminology.
Understanding Layflat Width (Choosing the Right Fit)
Layflat width vs. product size
Because layflat tubing is measured flat, it can be confusing if you are used to thinking in terms of bag opening width or circumference. As a simple guide, the opened tube circumference is roughly twice the layflat width. For bulky or irregular items, allow extra room so the film is not overstressed and so sealing remains easy and consistent.
Allowances for sealing
When cutting lengths, remember to allow enough material for a strong seal. If you are sealing both ends, you will need additional length at each end. Your heat sealer type and settings can influence how much allowance is appropriate.

Health and Safety
- Heat sealing: Use appropriate care when operating heat sealers. Follow the equipment manufacturer’s instructions and allow sealing bars to cool before handling.
- Cutting: Use suitable cutting tools and safe cutting practices to avoid injury.
- Packaging safety: Keep plastic packaging away from children and follow your site’s safety procedures for film products.
Ideal Applications and Use Cases
Variable-length packing lines
If you pack products that vary in length (for example, different versions of a component, kits, or mixed orders), lay flat tubing can reduce the need to stock multiple bag sizes.
Long items and awkward shapes
Tubing is often chosen for items that are long, narrow, or irregular—where standard bags either do not fit or create excessive waste.
Protection during storage and transit
A sealed polythene pack helps keep items clean and contained, reducing the risk of dust contamination and minor scuffing during handling.
Maintenance, Cleaning and Care
- Storage: Keep rolls in a clean, dry area away from direct heat sources to help maintain film condition.
- Handling: Avoid dragging rolls across rough surfaces to prevent edge damage.
- Sealing quality: If seals are inconsistent, check sealer temperature, dwell time, and pressure, and ensure the film is free from dust or debris at the seal area.
Case Study (Example Workflow)
Scenario: A warehouse packs mixed-length items daily and previously stocked many different bag sizes.
Approach: They switch to lay flat tubing in a suitable width and cut lengths as required at the packing bench, sealing with a heat sealer.
Outcome: Packing becomes more consistent, the number of bag SKUs is reduced, and operators can quickly create a correctly sized pack for each order without searching for the “right” pre-made bag.
Who is it for?
