1500mm - 120gsm Kraft Union - 100metre roll
Kraft Union
Overview
Kraft Union is a heavy-duty protective paper designed for demanding packing and lining tasks where extra resistance to moisture and contamination is helpful. This grade is commonly supplied as a wide roll for fast coverage of large surfaces, making it a practical choice for warehouse, manufacturing and export packing operations. Kraft Union is widely described by packaging suppliers as a bitumen/bituminised kraft paper that offers moisture resistance and is used for case lining, pallet lining and wrapping items that may be affected by damp or oily residues.
Because this product page may represent multiple roll options, the guidance below focuses on how Kraft Union is typically used and selected rather than on a single fixed roll length.
Key Features
Moisture-resistant barrier
Kraft Union is commonly described as bituminised/bitumen-laminated kraft paper, giving it improved resistance to moisture compared with standard kraft paper. This makes it useful as a liner or wrap where damp conditions, condensation or humidity could be a concern.
Protects against staining and contamination
Packaging suppliers commonly position Kraft Union for wrapping or separating components that may be oily or prone to marking. Used as an interleaving sheet or wrap, it can help reduce transfer of residues between items and packaging.
Strong kraft outer layer
“Kraft” papers are valued for strength and toughness in packaging applications. In day-to-day use this helps the sheet resist tearing during handling, wrapping and case lining.
Fast coverage for large items and surfaces
Wide rolls are ideal for lining cases, covering pallets, and wrapping bulky products. A roll format also supports efficient dispensing and consistent application.
Versatile protective paper for packing workflows
Kraft Union is commonly used across general packing, export preparation, storage protection and manufacturing environments where a paper-based protective layer is preferred.
Key Features (Bullet Summary)
- Moisture-resistant, bituminised kraft union paper (as commonly described by packaging suppliers)
- Suitable for case lining and pallet lining
- Useful for wrapping items that may be affected by damp or oily residues
- Strong kraft paper feel for robust handling
- Roll format supports quick coverage and efficient packing
Typical Uses
- Case lining: line cartons/wooden cases to add a protective barrier layer.
- Pallet lining and top-sheeting: place under or over goods to help protect from moisture and dirt during storage and transit.
- Wrapping components: wrap parts and assemblies to reduce exposure to damp conditions and help prevent marking.
- Interleaving/separation: separate stacked items to reduce scuffing and transfer of residues.
- Export packing: add an extra protective layer inside export cartons and cases where humidity changes may occur.
Kraft Union — Full Product Guide
Introduction
When you need more than standard kraft paper, Kraft Union is a widely used protective paper option. It is commonly referenced by packaging suppliers as a bitumen-treated kraft paper that provides a moisture-resistant barrier, making it suitable for lining, wrapping and separating goods in storage and transit. This guide explains how it works, how to choose it, and how to use it effectively in real packing workflows.
How It Works
Kraft Union is typically described as a kraft paper combined with a bitumen/bituminised layer. In practical terms, this construction is used to improve resistance to moisture and help reduce the risk of damp ingress reaching the packed item. In packing operations, it is often used as:
- a liner inside cases or cartons,
- a wrap around products or bundles, and
- a separator between items or layers.
Because it is supplied on a roll, it can be cut to length as needed, supporting repeatable packing processes and reducing time spent handling multiple sheets.
Materials and Construction
Across supplier descriptions, Kraft Union is commonly referred to as bituminised (bitumen-laminated) kraft paper. The kraft component provides strength and tear resistance for handling, while the bitumen treatment is used to enhance moisture resistance. If you are matching an existing specification, confirm the exact grade and construction required for your application (for example, whether you need a particular barrier performance or compatibility with your packing method).
Floor Type Compatibility (Warehouse & Packing Areas)
Although Kraft Union is primarily a packaging material rather than a floor covering, it is often used in warehouse environments where goods are staged on pallets or in cases. For best results:
- Use on clean, dry staging surfaces to avoid trapping debris that could mark products.
- When lining pallets, ensure the paper is flat and well-fitted to reduce snagging during forklift handling.
- If used as a top sheet, consider adding edge protection or stretch wrap to keep the sheet in place during transit.
Health and Safety
As with most roll materials used in packing, safe handling is mainly about manual handling and cutting practices:
- Cutting: use appropriate safety knives and cutting surfaces; keep hands clear of the cutting path.
- Manual handling: wide rolls can be awkward—use two-person lifts or a roll dispenser/stand where appropriate.
- Housekeeping: keep offcuts tidy to reduce slip/trip risks in packing areas.
If your site requires formal risk assessments or COSHH-style documentation for packaging materials, confirm requirements internally and with your supplier.
Ideal Applications and Use Cases
Kraft Union is commonly chosen when standard kraft paper is not enough and you want a paper-based protective layer with improved moisture resistance. Typical use cases described by suppliers include:
- Moisture-prone storage: lining cases for goods stored in variable humidity conditions.
- Transit protection: pallet lining/top-sheeting to help protect from damp and dirt.
- Industrial components: wrapping parts that may have light oily residues or that need separation to reduce marking.
- Export packing: adding a barrier layer inside export cartons and cases.
Maintenance, Cleaning and Care
Kraft Union is a consumable packaging material, so “maintenance” is mainly about storage and handling:
- Store rolls dry and protected from direct moisture to preserve performance.
- Keep rolls wrapped until use to reduce dust contamination.
- Use a dispenser where possible to prevent edge damage and improve cutting accuracy.
- Rotate stock (first-in, first-out) to keep materials in best condition.
Case Study (Typical Packing Workflow)
Scenario: A warehouse ships mixed industrial components on pallets and in cartons. Some items are sensitive to damp conditions during storage and transport, and some may carry light residues from manufacturing.
Approach:
- Line cartons/cases with Kraft Union before loading.
- Use cut lengths as interleaving sheets between layers of components.
- Add a top sheet over palletised goods before stretch wrapping.
Outcome: A consistent protective barrier layer is added to the packing process, helping reduce the risk of moisture-related issues and limiting marking/transfer between items during transit.
Who Is It For?
- Warehouses and fulfilment teams needing a robust liner/wrap for pallets and cases.
- Manufacturers packing components that benefit from separation and barrier protection.
- Export packers looking for a paper-based moisture-resistant lining material.
- Maintenance and engineering stores protecting parts in storage.
Colours / Features Available
Kraft Union is typically supplied as a kraft-style protective paper. Product appearance and finish can vary by grade and supplier. If you need a specific finish or performance characteristic, confirm the exact specification before ordering.
Sizes Available
This listing may include multiple roll options. When selecting a roll, consider:
- Roll width: choose a width that covers your pallet/case dimensions efficiently with minimal waste.
- Roll length: select based on throughput and how often you want to change rolls.
- Basis weight (GSM): higher GSM generally indicates a heavier, more robust sheet; match to the level of protection needed.
If you are unsure which option best fits your packing process, share your typical case/pallet sizes and usage rate and we can help you choose the most efficient roll format.
