1200mm - 120gsm Kraft Union - 100metre roll
Kraft Union
Overview
Kraft Union paper (sometimes referred to as bitumen kraft union) is a heavy-duty protective paper designed for demanding packing and surface-protection tasks. It combines a strong kraft paper face with a laminated barrier layer to help resist moisture and contamination, making it a practical choice when you need more protection than standard kraft paper alone. This Kraft Union roll format is ideal for fast coverage of large areas and for wrapping bulky or irregular items during storage, handling and transport.
Commonly used across manufacturing, warehousing, removals, construction and engineering environments, Kraft Union is valued for its balance of strength, flexibility and barrier performance. It can be used as an interleaving layer, a wrap, or a temporary protective cover to help reduce scuffs, dust, light splashes and general handling marks. Because it is supplied on a roll, you can cut to length as required, helping to minimise waste and tailor protection to the job.
Key Features
Barrier-backed protection
Kraft Union is made with a kraft paper layer combined with a bitumen/laminated barrier. This construction is widely described as helping provide resistance to water, oil and grease, making it suitable where ordinary paper could quickly become compromised.
Tear and puncture resistance
The union construction is commonly specified for improved durability, helping the paper resist tearing and puncturing during wrapping, palletising and general handling.
Flexible roll format
Supplied as a roll for easy dispensing and quick coverage. Cut to the length you need for wrapping, lining, interleaving or surface protection.
Multi-purpose protective paper
Used for wrapping products, protecting surfaces, separating layers, and lining crates or cartons—particularly where a moisture-resistant paper is preferred.
Helps reduce scuffs and contamination
Acts as a sacrificial layer between products and external contact, helping reduce dust, dirt and handling marks during storage and transit.
- Barrier-backed kraft union construction for added protection compared with standard kraft paper
- Designed for durability with improved tear/puncture resistance
- Cut-to-length convenience from a roll for efficient use
- Suitable for wrapping, interleaving and lining across many industries
- Helps protect against moisture and contaminants in typical handling environments
Typical Uses
- Wrapping and protecting metalwork, components and fabricated parts
- Interleaving between stacked items to reduce rubbing and scuffing
- Lining crates, cartons and pallets for added barrier protection
- Temporary surface protection during storage, refurbishment or fit-out work
- General industrial packing where moisture resistance is beneficial
Kraft Union Paper Roll — Full Product Guide
Kraft Union paper is chosen when you need a tougher, more protective paper wrap—especially in environments where moisture, oils or grease may be present. Below is a practical guide to help you decide if Kraft Union is the right protective paper for your application and how to get the best performance from it.
How It Works
The key idea behind Kraft Union is the combination of two functional layers:
- Kraft paper face provides strength, stiffness and a protective outer surface that is easy to handle and wrap.
- Barrier layer (bitumen/laminate) helps reduce penetration from moisture and oily contaminants, supporting cleaner, drier protection in transit and storage.
In practice, this means you can use Kraft Union as a wrap or liner that is more resilient than standard kraft paper, particularly when conditions are less than ideal (e.g., mixed loads, damp warehouses, or items that may carry light residues).
Materials and Construction
Supplier specifications commonly describe Kraft Union as kraft paper laminated with a bitumen layer. This laminated construction is widely referenced as providing resistance to water, oil and grease, while also improving tear and puncture resistance compared with plain paper. The result is a protective paper that remains flexible enough to wrap around corners and contours, yet robust enough for industrial handling.
Floor Type Compatibility
If you are using Kraft Union as a temporary floor or surface protector, it is best suited to short-term protection where you want a paper-based cover with added barrier performance. As with any protective covering, compatibility depends on the surface finish and site conditions:
- Hard floors (sealed concrete, tiles, vinyl): can be used as a protective layer to reduce dust and light splashes; ensure the surface is clean and dry before laying.
- Timber/laminate floors: use caution and test in an inconspicuous area; avoid trapping moisture underneath any covering.
- Carpet: generally used more for wrapping/lining than for carpet protection; if used, ensure it is secured and does not create trip hazards.
Always secure edges appropriately and avoid creating slip or trip risks in walkways.
Health and Safety
- Manual handling: rolls can be heavy; use safe lifting techniques and team lift or mechanical assistance where appropriate.
- Cutting: use a suitable safety knife and cutting surface; keep hands clear and store blades safely.
- Trip hazards: if used as a surface covering, tape down edges and overlaps and keep walkways clear.
- Storage: store rolls upright or on racking to prevent damage and reduce the risk of rolling.
Ideal Applications and Use Cases
Kraft Union is commonly selected for:
- Engineering and metal fabrication: wrapping parts and assemblies to help protect from moisture and workshop contaminants.
- Warehousing and distribution: lining pallets or cartons and separating layers in mixed shipments.
- Removals and storage: wrapping furniture panels, worktops and bulky items where a tougher paper is preferred.
- Construction and fit-out: temporary protection of surfaces and materials during on-site works.
If your priority is cushioning rather than barrier protection, consider pairing Kraft Union with a cushioning material (e.g., corrugated wrap or bubble wrap) and using Kraft Union as the outer protective layer.
Maintenance, Cleaning and Care
Kraft Union is a consumable protective material, so “maintenance” is mainly about correct storage and handling:
- Keep rolls dry and away from direct water exposure to preserve performance.
- Avoid crushing the roll edges, which can make dispensing and cutting more difficult.
- Cut cleanly to reduce ragged edges that can snag during wrapping.
- Replace when contaminated: if the paper becomes heavily soiled or saturated, remove and replace to maintain protection.
Case Study (Typical Example)
Scenario: A small engineering workshop ships fabricated metal components to customers. Items are stored briefly in a warehouse area where humidity can vary, and components may have light oily residues from machining.
Approach: Components are interleaved and wrapped with Kraft Union paper before being placed into cartons or onto pallets. The barrier-backed construction helps reduce the risk of moisture ingress and helps prevent oil/grease transfer to outer packaging.
Outcome: Improved presentation on arrival and fewer handling marks compared with plain kraft paper alone, with the added benefit of quick cut-to-length wrapping from a roll.
