In the eco-friendly market of today, kraft paper has become a top material for green packaging solutions. Whether you’re operating an e-commerce store, operating retail stores, or seeking green alternatives for your products, learning about kraft paper and its uses can go a long way in optimizing your packaging strategy.
What Is Kraft Paper?
Kraft paper is a strong packaging material produced through the kraft process, whereby wood is turned into wood pulp with a mixture of sodium sulfide and sodium hydroxide. This is a chemical process that maintains the wood fibers’ strength, leaving it much stronger than other paper types.
The term “kraft” is derived from the German word for “strength,” which aptly sums up this material’s chief property. Kraft paper can be identified by its characteristic brown color, although it also comes in white and other colors.
The Manufacturing Process
The kraft process is as follows:
Wood preparation: Pine trees are stripped of bark and chipped
Pulping: Wood chips are processed with chemicals that dissolve lignin and untangle fibers
Washing and bleaching: Pulp is washed and may be bleached if white kraft is needed
Sheet formation: Pulp is spread out thinly and dried
Finishing: Paper is pressed, dried, and rolled to be distributed
This chemical pulping gives paper that has exceptional tensile strength without being too heavy—excellent for application in packaging.
Types of Kraft Paper
Kraft paper is available in a number of different varieties, each for particular uses:
Natural Kraft Paper
This is the traditional brown kraft paper that most are familiar with. Its natural colour is due to the unbleached wood pulp, which leaves it with maximum strength and ideal for bespoke packaging solutions.
Bleached Kraft Paper
When the pulp is bleached, it produces white kraft paper. This type provides comparable strength characteristics but offers a clean background for printing and branding.
Virgin Kraft Paper
Produced from wood pulp in direct form without any use of recycled material, virgin kraft gives maximum strength along with cleanliness and can be used for food packaging purposes.
Recycled Kraft Paper
Produced on the basis of post-consumer waste, recycled kraft paper offers an environmentally friendly solution with comparable strength characteristics.
Specialized Kraft Papers
The market also provides specialized variants such as:
Machine glazed kraft: Has a shiny surface on one side
Sack kraft: Further reinforced for heavy-duty usage
Ribbed kraft: Has visible lines for extra strength and visual attraction
Kraft Paper Packaging Environmental Advantages
In this day and age, when consumers are looking for sustainability, kraft paper provides several environmentally friendly benefits: It breaks down naturally over a few weeks to months.
Recyclable: Simple to recycle using conventional recycling methods
Made from trees, which, when properly harvested, are a renewable resource.
Lowered carbon emissions: particularly with recycled kraft.
Less chemical use: More natural kraft processing uses less chemicals.
Practical Gains
Apart from environmental concerns, kraft paper has many practical benefits:
Greater strength: handles and ships under pressure. Appropriate for load-bearing packaging, filling, and wrapping. Simple to decorate, stamp, or print Usually cheaper than packaging materials created by people. Permeability: Let some items breathe properly.
Popular Kraft Paper Packaging Applications
Retail Packaging: In Custom retail settings, kraft packaging boxes are being used more and more for:
Product boxes and containers
Shopping bags
Gift wrapping
Tissue paper
Hang tags and labels
The natural, earthy appearance of kraft paper helps brands convey their environmentally friendliness while providing functional packaging.
Food Industry Applications
The food industry has found uses for kraft paper across the following applications:
Coffee bags
Bakery packaging
Take-out containers
Sandwich wraps
Food trays
Food-grade kraft paper delivers the ideal balance of protection, presentation, and sustainability for consumable foods.
E-commerce Packaging
Online stores make extensive use of kraft paper for:
Shipping boxes
Mailer envelopes
Void fill and cushioning
Tape and sealing materials
Wrapping products
The strength of kraft paper makes it perfect for enduring the rigors of shipping and handling in the e-commerce supply chain.
Kraft Paper vs. Alternative Packaging Materials
Kraft Paper vs. Plastic
In comparison to plastic packaging materials, kraft paper has:
Improved environmental profile
Natural beauty
Biodegradability
Often cheaper
Less petroleum usage
Yet plastic can give improved moisture barrier and clarity.
Kraft Paper vs. Corrugated Cardboard
Both corrugated cardboard and kraft paper each have their own place in packaging: Corrugated is stronger for heavier loads
Kraft paper is more flexible and appropriate for wrapping
Corrugated provides more cushioning
Kraft paper is usually cheaper for small applications
Most packaging solutions ultimately employ both materials combined for optimal performance.
Customizing Kraft Paper Packaging
Printing on Kraft Paper
Kraft paper accepts various printing methods:
Flexographic printing: Ideal for large runs and simple designs
Digital printing: Perfect for shorter runs and detailed designs
Screen printing: Provides vibrant colors and special effects
Letterpress: Creates an elegant, premium look
The natural texture and color of kraft paper create a distinctive canvas for branding that stands out in today’s marketplace.
