Consider the details
The gold standard of eco-friendly, plastic-free packaging
Brown kraft paper represents authenticity, sustainability, and industrial strength. Produced from unbleached virgin wood pulp or 100% post-consumer recycled paper, its long wood fibres provide exceptional burst strength and puncture resistance. Ideal for postal wrapping, gift wrapping with rustic twine, and protecting products in transit.

Heavy-Duty Kraft Paper Sheets: Structural Integrity, Burst Strength & Pallet Logistics
Derived from the German word for ‘strength’, kraft paper has long been the backbone of heavy industrial packaging and reliable parcel protection. Manufactured through the sulphate chemical pulping process, virgin kraft retains long, unbleached softwood fibres that confer superior tensile strength, burst resistance, and puncture durability compared to all other paper substrates. For 40 years, QPack has supplied British distribution networks, engineering works, and artisan retailers with high-performance ribbed, smooth, and heavyweight kraft sheets engineered to survive the rigours of domestic courier handling and international freight.
1. The Physics of High Burst Strength
Why virgin softwood kraft outperforms recycled paper under courier impact:
- Long-Fibre Softwood Matrix: Virgin Scandinavian pine fibres measure up to 3.5mm in length, forming tightly interwoven chemical bonds that resist tearing under sharp corners.
- Mullen Burst Strength Rating: 90gsm virgin kraft withstands over 350 kPa of hydrostatic pressure, preventing sharp box edges and metal parts from puncturing out.
- Tear Factor & Tensile Energy Absorption (TEA): Exceptional elasticity allows the paper to stretch slightly under courier impact without catastrophic splitting.
- Ribbed Machine Glazed (MG) Kraft: Distinctive linear mechanical ribs provide directional stiffness, structural backbone, and classic heritage aesthetics.
2. GSM Calipers: From Lightweight Wrap to Heavy Pad
Selecting the exact grammage for your specific shipping weight threshold:
- 70gsm Light Kraft Wrap: Pliable, easy to fold and tape; the ideal parcel wrap for apparel, books, craft goods, and lightweight domestic retail parcels.
- 88–90gsm Standard Parcel Kraft: The UK commercial shipping workhorse. Meets Royal Mail and courier parcel specifications for robust parcel exterior wrapping.
- 120–140gsm Heavyweight Kraft: Heavy-duty industrial barrier sheets for wrapping metal extrusions, automotive spares, heavy machinery parts, and furniture.
- 200–300gsm Pallet Layer Pads: Rigid kraft board pads placed between pallet tiers to distribute weight, stabilise stacks, and prevent carton crushing during transit.
3. Printing & Custom Branding on Brown Kraft
Mastering ink absorption and colour reproduction on natural unbleached fibres:
- High-Pigment Water-Based Inks: Formulated with elevated pigment solids to overcome the dark background tone of unbleached kraft without dulling.
- Black & Earth-Tone Optimisation: Deep carbon black, rich forest green, burgundy, and warm terracotta create striking organic, eco-luxury aesthetics.
- Opaque White Underprinting: Applying an opaque white ink base allows bright corporate colours to pop cleanly on brown kraft surfaces.
- Flexographic Rotary Precision: Continuous repeat patterns, handling instruction icons (e.g., fragile, handle with care), and barcode clarity verified to ISO standards.
4. 100% Circularity & Plastic-Free Mandates
Reinforcing your brand’s circular economy and plastic-reduction commitments:
- 100% Biodegradable & Recyclable: Kraft paper degrades naturally in soil within weeks and is eagerly reclaimed by UK pulp mills for corrugated board production.
- FSC® Certified Forestry: Pulp sourced strictly from responsibly managed Scandinavian forests with replanting guarantees and biodiversity monitoring.
- Tape Adhesion Excellence: The natural fibrous porosity of kraft creates an unbeatable chemical bond with water-activated gummed paper tape and hot-melt adhesives.
- Zero Plastic Footprint: Completely eliminates non-recyclable polythene shrink films and plastic pallet covers from your warehouse outbound docks.
Production & Workflow

Frequently Asked Questions

What makes kraft paper stronger than standard wrapping paper?
Kraft paper is produced using the 'Kraft process' (invented by Carl F. Dahl), which uses chemical sulphate pulping rather than mechanical grinding. This process preserves the long cellulose fibres of virgin softwood trees and dissolves lignin (the natural wood glue that makes standard paper brittle). The result is an extraordinarily tough, pliable sheet with dramatically higher tear, tensile, and burst resistance under courier transit stress.
What is the difference between ribbed kraft and smooth kraft paper?
Ribbed kraft features prominent linear ridges pressed into the paper during the paper machine glazed (MG) drying cylinder process; these ribs provide structural rigidity, directional tear resistance, and a distinctive traditional aesthetic. Smooth kraft is calendered between polished rollers to create a flat, uniform surface that is better suited for fine detail logo printing and tape adhesion.
Can brown kraft paper be custom printed with our full company logo?
Yes. We operate specialised wide-web flexographic printing presses designed specifically for porous kraft papers. Using high-density water-based inks, we can print single-colour, two-colour, or full-coverage patterns including logos, eco certification badges, QR codes, and custom handling instructions.
What weight of kraft paper is recommended for wrapping heavy retail parcels?
For general retail and e-commerce parcels weighing up to 5kg, 70gsm to 90gsm virgin kraft provides ample burst resistance. For heavier parcels, industrial metal fittings, or products with sharp rigid corners up to 15kg+, we recommend our 120gsm or 140gsm heavyweight kraft sheets.
How do kraft pallet layer pads protect goods during transit?
Pallet layer pads (ranging from 140gsm heavyweight kraft up to 300gsm solid kraft liner) are placed between tiers of cardboard boxes or sacks stacked on a wooden pallet. They distribute top-down weight evenly across lower layers, prevent carton sagging, and introduce high-friction interlocking that stops boxes from shifting during lorry transport.
Is your brown kraft wrapping paper recyclable and compostable?
Yes, 100%. Our unprinted and water-based printed kraft papers contain no plastic coatings or toxic chemicals. They are 100% recyclable in domestic UK council paper collections and are home compostable, breaking down completely into natural organic matter within 6 to 12 weeks.
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.
