Kraft paper is paper made from pulp produced by the kraft chemical pulping process. This process separates wood fibres from much of the lignin that binds them together, producing pulp suitable for strong, flexible papers. The familiar brown version is unbleached, while bleaching produces white kraft grades. Its common packaging uses include bags, wrapping and liners for corrugated board.
For a brand choosing packaging, kraft offers a combination of physical usefulness and visual character. A warm brown surface can make a simple printed mark feel considered; a suitable paper grade can withstand the folds and pulling forces of a shopping bag. Its value comes from matching those qualities to the product, the package and the experience you want to create.
What varies between kraft papers?
Kraft packaging papers come in different weights, fibre compositions and surface finishes. Bag paper may prioritise strength and flexibility, while a paper used to wrap a rigid box may be chosen for its appearance, folding behaviour and ability to bond neatly to the board. Packaging sold under the kraft description can also contain virgin fibre, recovered fibre or a blend. Confirming the actual grade and fibre content gives you a useful basis for comparing samples and quotations.
Our guide to how kraft paper is made explains the pulping and manufacturing process in more detail.
The benefits of kraft paper for packaging
Useful strength with flexibility
Suitable kraft grades can resist pulling and tearing while remaining flexible enough to fold, wrap and form into bags. That combination matters when packaging changes shape during use: a bag opens around its contents, a gusset expands, and a wrapped item puts pressure on corners. The finished construction still carries much of the responsibility. For a bag holding a glass candle, the handle attachment, bottom construction and paper choice all affect reliable carrying. When we develop that kind of packaging, we consider these elements together.
A surface that contributes to the design
Brown kraft brings its own colour and texture to a package. Depending on the grade, the surface may feel smooth and restrained or show more visible fibre variation. That gives designers something to work with before adding ink or finishing. A jewellery box wrapped in carefully chosen kraft, with generous space around a small wordmark, can feel quiet and deliberate. The quality comes through proportion, clean edges, fit and the opening experience. Kraft can support that presentation without needing a busy printed surface.
Where kraft paper works well
Kraft can connect several parts of a packaging range visually, while taking a different physical role in each. A product sleeve, shopping bag and delivery box may share a brown paper appearance, but each needs a material and construction suited to its job.
| Packaging application | What kraft contributes | What makes the pack work |
|---|---|---|
| Shopping and gift bags | A printable surface with useful strength and flexibility. | A suitable paper grade, handle attachment, base and size for the intended contents. |
| Product wrapping and parcel fill | Flexible sheets that can wrap, separate or fill spaces around products. | The amount, shape and placement of the paper, matched to the protection needed. |
| Folding cartons and sleeves | A kraft paperboard or suitable kraft-faced construction with a distinctive appearance. | Appropriate stiffness, crease quality, fit and closure design. |
| Corrugated mailers | Kraft paper can form a liner around the fluted core. | The combined liner and fluting specification, box design and suitability for the delivery journey. |
| Rigid gift boxes | A kraft wrap that provides the visible surface and tactile character. | The underlying rigid board, wrapping quality and internal product support. |
A kraft-wrapped rigid box illustrates the distinction especially well. The kraft provides the surface you see and touch; the board underneath gives the box its shape and rigidity. An insert may hold the product in position, and separate transit packaging may protect it during shipping. Understanding these roles allows us to preserve the appearance a customer likes while developing the protection their product needs.
Designing colour and detail for the actual paper
The paper colour becomes part of the printed result. Many printing inks are partly transparent, so brown kraft can make a colour appear warmer, darker or less vivid than it does on white stock. A pale yellow logo that reads clearly on white may lose definition against brown. Dark lettering, stronger contrast or a light-coloured label can give the same brand a clearer expression on kraft.
Where a design depends on bright colour, white areas or close colour matching, the paper and printing route deserve early attention. Depending on the process, white ink or a white underprint may be possible; coverage and opacity affect the result. White kraft provides another starting point. Foil or an impressed detail may also suit a design, with the chosen stock and finish evaluated together. Each option changes the appearance, production work and cost.
A printed sample on the proposed paper helps resolve these choices. It lets you judge the relationship between the stock, ink, small text and finishing in your hand. At CMIC, we can develop suitable material and print options around the design, so you can compare their effect before committing to the final specification.
Making the environmental benefit specific
Kraft can support a simpler paper-based construction when its natural surface achieves the desired look with fewer added layers. For example, a printed kraft sleeve may provide enough presentation for a product without an additional decorative film. That is a useful design opportunity to examine alongside product protection and material quantity. The appropriate solution depends on what the complete pack has to do.
Recyclability depends on the finished packaging and the systems available where it is discarded. Plastic lamination, coatings, adhesives and attached components can affect how a paper package is collected and processed. Recycled content and fibre sourcing also need their own material documentation. If environmental performance is part of your reason for choosing kraft, carry that intention through the construction and support any public claims with information about the actual pack.
Choosing a kraft pack that works for your product
Start with the package’s job: carrying, wrapping, presenting, holding its shape or protecting during delivery. This helps narrow the useful paper and construction options. Gsm, or grams per square metre, measures the paper’s mass per unit area. It is helpful when comparing similar grades, while fibre composition, thickness and construction also affect performance. Two papers with the same gsm can feel and behave differently when folded into a finished pack.
Moisture is another design variable. Water can soften ordinary uncoated kraft and reduce its stiffness and strength; grease can leave visible marks. Treatments and coatings can change that behaviour, along with the feel, print surface and recycling considerations. Packaging expected to spend time on a damp bathroom shelf therefore needs a different evaluation from a dry retail gift wrap. The product’s likely surroundings help determine which version of kraft is suitable.
A filled prototype brings these decisions together. With the actual product inside, you can assess how the pack closes, where weight is carried, whether corners become stressed and how comfortably it opens. Shipping protection may also need appropriate testing for the intended distribution route. We can develop the structure, compare relevant paper options and coordinate specialist work where needed, turning a broad preference for kraft into a specification that serves the product.
Kraft is particularly appealing when its visible character and physical role reinforce each other: a flexible bag that feels dependable, a restrained sleeve that frames the product, or a neatly wrapped box that rewards a closer look. If you have a product in mind, talk with us about its packaging. Product dimensions, weight, the appearance you like and how it will reach the customer give us a useful starting point for exploring a suitable kraft solution.
