Essential Facts Highlighting Importance of Kraft Paper in Packaging Industry

What is Kraft Paper

Kraft paper is a material used in the packaging of various items. You can apply it in the manufacturing of encasing that can enclose light bakery goods or even industrial products. Businesses openly rely on Kraft material because of increased durability, efficiency and elasticity. The paper sheet is created from virgin and reused chemical pulp and has high flexibility and tear resistance features.

It comes in weights ranging from 30-300gsm and can be ordered in natural brown or bleached white, depending on the needs of the business or manufacturer. Both fully bleached (white) and brown kraft sheets are high-quality, strong, bright, and can tolerate any pressure.

Without printing, the product packaging is worthless, and the item enclosed inside can’t substantially impact the market. Additionally, printing on paper can elegantly enhance the display of your merchandise and make it more appealing for the audience. Getting the kraft material imprinted is easier because it can hold the printed text, labels or images.

Businesses can also use various colors on the kraft packaging to reinvigorate the look and make it charming for the end-users. Another key aspect distinctive from the others is its environment-friendly nature.

How Kraft Paper Is Made

Kraft paper is created using the Kraft process, which, like other papermaking techniques, entails chemically converting wood into wood pulp. Lignin and cellulose are the two main underlying components of wood. You must remove lignin from cellulose since it does not form excellent paper.

Wood chips are boiled in a “white liquor” of sodium sulphide and sodium hydroxide to achieve this state. The process separates the lignin and cellulose from the solid wood pulp, leaving a “black liquor” behind. The wood chips are now crushed into a pulp and filtered to eliminate bigger fragments. After being rinsed to eliminate any remaining cooking liquors, the pulp can be processed into various paper products.

For achieving the colour and appearance quality standards, the pulp must be bleached to the whiteness of 24 percent to 34 percent and the yellow and red values of the pulp must be kept reasonably steady, i.e., the bleached pulp’s hue must be stable.

Optimizing the pulping process is essential in improving the strength of fine kraft paper. In general, to improve the physical strength, uniformity, and flatness of the paper, the beating degree of the pulp must be increased while retaining its good air permeability and low tightness.

The press production method impacts the paper’s breathability, tightness, and smoothness. The pressing decreases the paper’s porosity, lowering the permeability and suction height while increasing the tightness.

During the drying process, the paper sheet eliminates humidity and undergoes changes in the properties of tightness, moisture absorption, airtightness, flatness, or dimension. The drying technique and procedure have a big role in these modifications. High temperature and drying with fast heating is thought to increase the paper’s softness, porosity, absorbency, and air permeability while lowering its tightness, transparency, and mechanical strength.


Types of Kraft Paper

Following are some of the main types of kraft paper available in the market:

Virgin Natural Kraft Paper

The clean and durable fibre composition of virgin natural kraft paper, as well as its inexpensive cost, makes it a great choice for heavy-duty applications requiring a high level of tear resistance.

Natural Recycled Kraft Paper

Natural recycled kraft paper is a more ecologically responsible alternative than virgin natural kraft paper. Yet, it still has the strength to do a good job with crates and liners for trays and containers and bottom cover for newspapers.

Colored Kraft Paper

Colored kraft paper comes in almost every hue of the rainbow. Its brilliant colours make it ideal for a variety of creative projects and fun backers for bulletin boards, school materials, scrapbooking, and other similar uses. You should use colored kraft paper if your target market comprises schools, daycares, or art academies.

Is Kraft Paper Recyclable

Yes, you can recycle the kraft paper. It is made from virgin wood pulp and is therefore organic. You have the luxury to recycle Kraft paper up to seven times. The recycling of kraft paper is fairly similar to recycling other types of paper. The kraft papers are gathered and sifted first to remove any impurities or toxins. After being sorted, the papers are sent to a mill, where the recycling process begins.

Unlike ordinary paper manufacturing and printing, kraft paper goes through a considerably simpler process that uses far fewer chemicals in production. Pulping, washing, screening, deinking, dispersion, kneading, bleaching, water treatment, and waste processing are all part of recycling. New paper goods are created after the recycling process.

The process of recycling kraft paper involves certain hurdles like the fear of contamination. Often, the individuals are unaware of the recycling process, as seen by how they utilize and dispose of objects.

Oil, filth, scrap steel, and food waste are contaminants in the recycling process. Chemical methods are required to remove the majority of pollutants. The biodegradable brown wrapping paper needs to be handled with great care so you can reuse it in the future.

Is Brown Kraft Paper Recyclable

Brown paper is made out of the same basic elements as all other types of paper: wood pulp fibre. The major distinction is in how the wood pulp is transformed into paper.

The fibres are broken down using sodium hydroxide and sodium sulphide in the Kraft process. It creates durable paper. Another significant distinction between brown and white paper is that brown paper is not bleached, making it a more environmentally conscious option.

Brown and white papers go through the same recycling process, with the fibres pulped, cleaned, and removed from any inks or other impurities. This pulp can then be dried and pressed to create paper goods in the same manner as virgin materials are.

Keep an eye out for synthetic materials like tape or inks and non-paper coverings like plastic. Brown paper often does not have this coating, although many sparkly or bright sheets have.

Lower Cost of Paper

The cost of wrapping is added to the final price of any product, which impacts how well it fares with the competition in the market. Plastic packaging is more costly than kraft paper packaging. It also has a lower weight than packaging with features like zip closures. The cost of transportation is determined by the weight of the packing, which impacts the ultimate consumer price in kraft paper packaging.

Kraft Paper Uses

There are many ways we can incorporate kraft material in the packaging to make the product safe and enhance its shelf life. Following are some of the ways through which we can use kraft paper:

  • Artwork

Apart from its usage in the product packaging, we can also use kraft paper as a canvas. The painters and artists can use it for drawing, painting and making some aesthetically appealing artworks. You can get the kraft paper in different colors and be more creative in the drawing. Kids can start to learn numbers and alphabets by drawing them on paper.

  • Protection of Snacks

Food businesses prefer to use kraft because it’s cheap, and they can convey the feel of environmental protection due to its impeccable features. The paper is great at holding the snacks like chips, burgers, wraps, sweets, and much more. You can ask the packaging provider to mold it in a specific shape or size. Furthermore, the business owners can ask the printing enterprise to apply the logo or stickers to create a personalized feel for the target audience.

  • Wrapping of Gifts

There are no constraints if we speak about the colors of kraft paper. It comes in a natural brown color, and you can also go for the option of colored kraft paper. You can send the items wrapped in kraft paper and adore them with the ribbons and aesthetic designs to make it more tempting for the audience. The gifts packed inside the kraft paper can make special occasions more memorable. Because it’s neutral, kraft paper is more favorable to creativity than colorful, textured paper because you can customize and enhance it whatever you like.

  • Covering the Floor

During the construction, the wooden floor of the house can be damaged easily. Therefore, the kraft paper is applied to the bottom to protect its surface. It’s common to use kraft paper on the floor because it acts as a shield and prevents fiberglass from damaging the floor and tiles.

  • Protection of Books

Keeping the books protected and secured from dust damage is a huge challenge. But, kraft paper offers direct assistance as it can be wrapped around the books and act as a cover to keep the dust and other impurities away. The pages of a book can remain safe as any damage effects don’t penetrate deep inside to affect the book’s condition.
