What is Kraft Packaging?

Why are They Called Kraft Bags?

The name “kraft” comes from the German word for strength, “Kraft,” reflecting the remarkable durability and resilience of kraft paper. The kraft process is a chemical pulping process that creates strong and robust paper by breaking down wood chips with a chemical solution. This process results in a paper that retains its natural toughness, which makes it an ideal material for making bags that are capable of holding heavier goods without tearing.

Kraft bags are popularly used in both retail and industrial sectors because of their strength, which allows them to carry various products, ranging from clothing to food. These bags are particularly common in grocery stores and packaging applications for shipping goods.

Common Uses of Kraft Packaging

Kraft packaging is widely used across different industries due to its affordability, strength, and eco-friendliness. Here are some of the most common uses:

1. Retail Packaging:
   Kraft paper bags and boxes are extensively used in retail stores. The natural look of kraft paper gives products a premium and eco-conscious feel. Retailers often use kraft paper bags for shopping bags, gift bags, and even for packaging products in bulk.
2. Food Packaging:
   In the food industry, kraft paper is used for packaging dry foods such as cereals, snacks, and baked goods. Its breathable nature allows food products to stay fresh without becoming soggy, making it an ideal choice for packaging consumables. Additionally, kraft paper is non-toxic, ensuring the safety of food items.
3. Shipping and Industrial Packaging:
   Kraft paper is also used extensively in shipping bags, as it offers durability and strength to protect goods during transit. It’s commonly used for making shipping bags, boxes, and wraps. Its tear resistance ensures that the contents remain secure, reducing the risk of damage.
4. Gift Wrapping and Crafting:
   Many people use kraft paper for DIY projects and gift bags wrapping. Its rustic appearance makes it a popular choice for crafting, and it can easily be customized with prints or labels to suit different occasions.

Types of Kraft Paper

Kraft paper comes in various types, each with its specific features and applications. Below are the most common types of kraft paper used in packaging:

Coated Unbleached Kraft (CUK)

Coated Unbleached Kraft (CUK) paper is a type of kraft paper that has been treated with a coating to improve its printability and surface quality. However, it remains unbleached, which means it retains its natural brown color. CUK is widely used in packaging products that require a premium finish, such as branded bags, boxes, and labels.

• Applications: CUK is often used for high-end product packaging, including luxury items, food packaging, and gift packaging.
• Advantages: It offers a smooth printing surface while maintaining the natural strength and durability of kraft paper.

Solid Bleached Kraft Paper (SBS)

Solid Bleached Kraft (SBS) paper is a bleached version of kraft paper, which results in a white or off-white appearance. This type of paper has a smooth surface that allows for excellent print quality, making it suitable for applications where aesthetics and visual appeal are important. SBS is widely used for premium packaging applications.

• Applications: SBS is commonly used for food containers, cosmetic packaging, and high-quality retail packaging.
• Advantages: It offers excellent printability and a clean, crisp appearance, making it ideal for packaging products that need to stand out.

Coated Recycled Board (CRB)

Coated Recycled Board (CRB) is made from recycled kraft paper that has been coated to improve its strength and printability. It provides an eco-friendly alternative to traditional kraft paper while still maintaining its durability and functionality. CRB is increasingly being used by businesses that want to reduce their environmental footprint while still benefiting from kraft paper’s strength.

Advantages: It offers the same strength and durability as virgin kraft paper while being more sustainable and environmentally friendly.

Applications: CRB is used in packaging products such as food containers, product boxes, and mailing envelopes.

The Benefits of Kraft Paper

What is the Advantage of Kraft Paper Packaging?

Kraft paper offers several key benefits that make it an attractive choice for packaging:

1. Strength and Durability: Kraft paper is known for its strength and resilience. This makes it suitable for packaging heavy-duty products and shipping fragile items.
2. Eco-Friendly: Kraft paper is recyclable and biodegradable, making it a sustainable choice for businesses that want to reduce their environmental impact. Additionally, the kraft process uses fewer chemicals, making the paper production process more eco-friendly compared to other types of paper.
3. Versatility: Kraft paper can be used for a wide variety of packaging applications, from bags and boxes to wraps and pouches. Its natural color and texture give it a rustic and authentic appeal, making it popular in retail packaging.
4. Cost-Effective: Kraft paper is generally more affordable than other types of paper packaging materials, making it an attractive option for businesses looking to cut costs while still maintaining high-quality packaging.

What is the Disadvantage of Kraft Paper Packaging?

While kraft paper has many advantages, it also has some limitations:

1. Not Waterproof: Kraft paper is not naturally water-resistant, which means it can absorb moisture and become weakened when exposed to wet conditions. To mitigate this, it may need to be coated or lined for specific applications, such as food packaging.
2. Limited Printability: The rough texture of kraft paper can make it more difficult to print with vivid colors and fine details compared to other types of paper. While it can still be printed on, the results may not be as sharp or vibrant as other materials.
3. Limited Use in Certain Industries: While kraft paper is perfect for dry products, it may not be suitable for all types of products, especially those requiring high resistance to moisture or those that need a polished, glossy appearance.

Kraft vs. Regular Paper

When comparing kraft paper to regular paper, the key differences lie in their production process, strength, and appearance:

• Production Process: Regular paper is typically made from bleached wood pulp, while kraft paper is made through the kraft process using a stronger chemical solution. The kraft process produces paper with longer, stronger fibers, making it more durable.
• Strength and Durability: Kraft paper is much stronger than regular paper due to the longer fibers. This makes it better for packaging heavy items or those that need extra protection.
• Appearance: Regular paper is often smoother and lighter in color, while kraft paper has a rustic, natural look due to its unbleached fibers.

How to Make Kraft Paper

Step 1: Pulping

The process begins by breaking down wood chips into wood pulp using a chemical solution (sodium hydroxide and sodium sulfide). This process separates the cellulose fibers from the lignin, creating a slurry of fibers.

Step 2: Washing and Bleaching

The pulp is washed to remove any remaining impurities. In some cases, it is bleached to create lighter-colored paper, although kraft paper is often left unbleached to retain its natural brown color.

Step 3: Pressing and Drying

The pulp is then pressed to remove excess water and form paper sheets. The sheets are dried using large rollers to create smooth, strong sheets of kraft paper.

How to Print Kraft Paper

Printing on kraft paper requires special consideration due to its rough surface. Here’s how to do it:

Step 1: Prepare Your Design

Ensure that the design is suitable for kraft paper. Due to its texture, fine details may not show up as clearly. Choose simpler, bolder designs that will work well with the natural texture of the paper.

Step 2: Choose the Right Ink

Opt for eco-friendly inks that will adhere well to the surface of kraft paper. These inks typically use water-based or vegetable-based formulas that are both effective and sustainable.

Step 3: Printing Methods

Flexographic printing or offset printing are common methods used for printing on kraft paper. These techniques allow for high-quality print applications while maintaining the strength of the paper.
