Consider the details
Maximum burst and tear resistance for demanding industrial packing
When standard 70gsm paper isn't strong enough to resist sharp metal edges, heavy engineered components, or stacked pallet friction, our heavyweight kraft sheets deliver heavy-duty durability. Sourced from high-tensile virgin wood pulp fibres, they provide a rigid, puncture-resistant barrier.
- Heavyweight 120gsm, 150gsm, and 180gsm thick kraft paper stock
- High puncture resistance prevents sharp corners from piercing through
- Ideal for pallet layer interleaving pads, stabilizing freight shipments
- Available in pre-cut standard pallet sizes: 800x1200mm (Euro) & 1000x1200mm (Standard UK)

B2B Technical Specification & Engineering
Heavyweight Kraft Packing Sheets: High Burst Strength & Pallet Layer Protection
In industrial engineering, automotive manufacturing, architectural metalwork, and bulk pallet logistics, standard wrapping papers lack the tensile stiffness and puncture resistance required to protect heavy cargo. Heavyweight kraft packing sheets (ranging from 120gsm virgin kraft up to 300gsm solid kraft linerboard) deliver extreme physical protection against abrasive friction, sharp metal burrs, heavy mechanical impact, and pallet tier compression. Engineered from long-fibre virgin Scandinavian softwood pulp, these industrial sheets withstand grueling transit rigours across road, rail, and sea freight. Below, our industrial packaging engineers outline the structural metrics of heavyweight kraft sheets.
01
Superior Mullen Burst & Puncture Resistance
Why heavyweight virgin kraft outperforms recycled boards under heavy impact:
- Long Softwood Virgin Fibres: Unbleached pine cellulose fibres interlock to create an ultra-dense structure with extreme tear propagation resistance.
- High Burst Pressure Rating: 140gsm kraft withstands over 550 kPa of burst pressure, preventing sharp machine parts, tools, and metal corners from puncturing through.
- High Tensile Energy Absorption (TEA): Flexes under courier drop impact without brittle fracturing or seam bursting.
- Abrasive Barrier: Protects painted automotive panels, anodised aluminium extrusions, and polished stainless steel from transit friction rub.
02
Pallet Layer Pads & Stacking Stability
Preventing pallet collapse, crushing, and load shifting during lorry transport:
- Interlocking Friction Coefficient: Placed between tiers of boxes or sacks, heavyweight sheets create a high-friction plane that locks stacked cartons together.
- Load Weight Equalisation: Distributes top-down pallet weight evenly across lower carton tiers, preventing lower boxes from bowing or crushing.
- Base Pallet Lining: Shields bottom carton layers from wooden pallet splinters, nails, dampness, and road grime.
- Top Dust & Security Covers: Placed under pallet stretch wrap to shield top cartons from warehouse dust, sunlight UV fading, and pilferage.
03
GSM Range & Caliper Specifications
Matching heavy paper weights to specific industrial applications:
- 120gsm Heavy Kraft Paper: Pliable enough for manual wrapping of heavy tools, metal rods, and furniture while delivering high puncture resistance.
- 140gsm Extra-Heavy Kraft: The industrial benchmark for parcel wrapping heavy commercial consignments up to 25kg.
- 200–300gsm Rigid Kraft Linerboard: Rigid flat boards used exclusively as pallet tier divider pads and heavy interleaving sheets.
- Custom Millimetre Sizing: Standard pallet sizes (1200 x 800mm Euro, 1200 x 1000mm UK) or custom guillotined to exact crate dimensions.
04
100% Circularity & Environmental Auditing
Replacing plastic pallet sheeting with sustainable heavy paper:
- 100% Recyclable in Paper Mills: Highly sought after by paper recycling mills due to the valuable long virgin fibres it contributes to the recycling stream.
- FSC® Certified Sourcing: Harvested exclusively from audited Scandinavian working forests with full Chain-of-Custody compliance.
- Total Plastic Elimination: Replaces plastic corriboard and polythene sheets between pallet tiers, cutting plastic waste.
- Exempt from UK Plastic Tax: Pure paperboard composition ensures zero tax liability under the UK Plastic Packaging Tax.

Frequently Asked Questions
Clear answers on sizing, minimum order runs, artwork proofs, board calipers, and free tracked UK delivery.
What weight of kraft paper is needed to wrap heavy industrial metal parts?
For heavy engineered metal components, tools, automotive spares, and extruded profiles, 120gsm to 140gsm heavyweight virgin kraft is recommended. It delivers the essential burst and puncture resistance required to prevent sharp corners and metal edges from bursting through during courier transport.
How do kraft pallet layer pads improve warehouse transport safety?
Kraft pallet layer pads (typically 140gsm to 300gsm) are placed between horizontal layers of cartons on a pallet. They create a high-friction interlocking surface that prevents individual cartons from sliding or shifting during lorry braking and transit cornering. They also distribute top-down weight evenly to prevent lower boxes from collapsing.
What are the standard sizes for pallet layer sheets in the UK?
Our standard pallet sheet dimensions are 1200 x 1000mm (standard UK industrial pallet footprint) and 1200 x 800mm (Euro pallet footprint). We can also guillotine custom sheet dimensions to fit bespoke shipping crates, wire stillages, or shipping cages.
Is heavyweight kraft paper moisture resistant?
While uncoated heavyweight kraft is naturally porous, virgin long-fibre kraft resists ambient warehouse moisture and humidity significantly better than recycled cardboard. For extreme moisture or marine export requirements, we can also supply water-resistant barrier treated kraft.
Can heavyweight kraft sheets be printed with handling instructions or logos?
Yes! We can custom flexo-print heavyweight kraft sheets with single-colour or multi-colour company logos, safety handling pictograms (e.g., 'Fragile', 'Heavy Lift', 'This Way Up'), and custom barcodes.
Is heavyweight kraft paper recyclable and compostable?
Yes, 100%. Heavyweight virgin kraft is one of the most recyclable paper substrates in existence because its long, durable fibres add tremendous strength when re-pulped at paper mills. It is also 100% biodegradable and home compostable.
Have a specific requirement or custom dieline?
Our UK packaging specialists can verify bottle clearances, create tailored structural CAD dielines, and supply physical plain samples.
