Kraft paper has become a go-to solution for brands aiming to balance durability, sustainability, and cost-effectiveness in their packaging. Known for its distinctive brown hue and rugged texture, kraft paper is produced via a specialized pulping process that yields exceptionally strong, tear-resistant fibers. In today’s market—where consumer preferences increasingly lean towards eco-friendly materials—kraft paper offers both a rustic aesthetic and robust functionality. Recent industry reports project the global kraft paper market to grow from $17.06 billion in 2023 to $21.29 billion by 2028, reflecting rising demand across various sectors including food, e-commerce, and retail.
In this comprehensive guide, we’ll explore how kraft paper is produced, examine the different types of kraft paper available, discuss its key properties and benefits, and look at how businesses can leverage it in diverse packaging formats. We’ll also delve into sustainability considerations, cost factors, emerging trends, and practical tips for choosing the right kraft paper solution. By the end, you’ll have a thorough understanding of why kraft paper is a mainstay in modern custom packaging.
The Production Process of Kraft Paper
The word “kraft” comes from the German term for “strength,” which accurately reflects the resilient nature of kraft paper. Its production process is known for enhancing the durability and thickness of the final material, making it ideal for a range of packaging applications.
Kraft paper’s notable strength begins with a unique method of pulping wood chips (often pine or spruce). These chips are treated with a chemical solution that loosens and separates the wood fibers. Once the fibers are sufficiently broken down, they are rinsed to remove residual chemicals. Depending on the desired finish—like a lighter, bleached appearance—some batches may undergo an extra whitening step. Finally, the pulp is pressed into thin sheets and dried. Manufacturers can then add coatings or laminates if extra moisture or grease resistance is needed.
This streamlined process helps explain why kraft paper stands out in durability, as it retains a higher portion of the wood’s original fiber strength compared to many other papermaking methods.
Types of Kraft Paper
Kraft paper comes in a variety of forms, each suited to specific needs and branding goals. Understanding these distinctions will help you select the optimal material for your custom packaging project.
1. Natural (Unbleached) Kraft
- Appearance: Retains the classic brown color that many associate with kraft packaging.
- Fiber Strength: High tear resistance; excels in durability.
- Typical Uses: E-commerce mailers, grocery bags, shipping envelopes, and wrapping paper.
2. Bleached Kraft
- Appearance: Light or white shade, providing a cleaner, more refined look.
- Fiber Strength: Slightly lower than unbleached due to the bleaching process, but still robust.
- Typical Uses: When branding requires a lighter color palette, such as upscale product wraps or premium shopping bags.
3. Specialty Coated or Laminated Kraft
- Properties: Treated with coatings to improve moisture resistance or grease-repellency.
- Applications: Ideal for food items, deli wraps, or packaging that must withstand humid conditions.
- Customization: Can include additional printing or lamination layers for brand identity and high-impact visuals.
4. Recycled Kraft
- Eco-Focus: Produced partly or entirely from post-consumer waste, reinforcing a brand’s sustainability profile.
- Appearance: Similar to natural kraft but sometimes with subtle variations in texture or color.
- Best For: Companies aiming for a “green” image, e.g., organic products, artisanal crafts.
5. Colored Kraft Paper
- Range of Colors: Extends beyond brown or white; black kraft paper is especially popular for modern, minimalist packaging. Other colors include red, blue, and even pastels.
- Branding Potential: Offers a unique way to stand out on the shelf or online, while retaining kraft’s hallmark durability.
- Applications: High-end gift boxes, promotional event packaging, and fashion industry mailers where an on-brand color theme is essential.

Applications of Kraft Paper in Custom Packaging
Kraft paper’s inherent strength, eco-friendly reputation, and versatile appearance have contributed to its adoption in a wide range of packaging applications. Below is an overview of common uses that highlight how businesses can incorporate kraft paper into their custom packaging strategies.
Food & Beverage
Kraft paper’s durability and availability in coated or laminated versions make it ideal for food packaging. Dry goods such as flour or grains can be packaged in uncoated kraft. Bakery wraps, deli papers, and coffee bags often use coated kraft for grease and moisture resistance. This ensures products remain fresh and secure while reinforcing a natural, wholesome brand image.
Cosmetics & Beauty
In the cosmetics and beauty sector, the simple yet elegant look of kraft paper aligns well with brands that prioritize eco-friendliness and authenticity. Kraft paper can be used for wrapping soaps, lotions, or bath bombs, and bleached kraft with color printing is an option for higher-end skincare or makeup lines aiming for a minimal but polished visual presentation.
Electronics
Although it might seem counterintuitive, kraft paper is a popular filler and sleeve material in electronics packaging. Its tear resistance and cushioning qualities help protect gadgets during transit. Additionally, electronics companies benefit from the eco-conscious appeal of kraft when offsetting concerns about plastic packaging waste.
E-commerce & Retail
Online retailers often rely on kraft paper for shipping envelopes, tissue wraps, and brand-focused shopping bags. Given the growing competition in e-commerce, businesses look for packaging materials that are cost-effective, protective, and reflective of sustainability values. Kraft paper excels in all these areas, offering an unboxing experience that can be as visually appealing as it is practical.
Environmental Impact and Sustainability of Kraft Paper
Many brands choose kraft paper for its strong environmental credentials:
1. Renewable, Biodegradable, and Recyclable
– Forest Stewardship: When sourced responsibly, wood pulp feeds into a cycle of tree planting and minimal ecological disruption.
– Low Residue: Kraft paper disintegrates relatively quickly in compost or landfill conditions.
2. Lower Pollution in Production
– Chemical Recovery: The kraft process recycles much of the pulping chemicals, reducing waste.
– Reduced Bleaching: Unbleached kraft saves water and energy, further minimizing pollution.
3. Consumer Demand for Green Packaging
A majority of today’s consumers—particularly millennials and Gen Z—actively seek out products packaged in eco-friendly materials. Using kraft paper sends a clear signal that your brand values sustainability.
Cost Analysis: Kraft Paper in Packaging Solutions
Cost considerations can make or break a packaging strategy. While kraft paper generally offers an economical solution, specific nuances may influence your expenses.
