What is Kraft Packaging?

About 32% of all plastic used in the packaging industry won’t end up in the trash. The problem with that is plastic takes hundreds of years to decompose. In other words, aside from the ones that have ended up in the incinerator, every piece of plastic ever manufactured still exists to this day.

Kraft is an eco-friendly alternative to plastic packaging and might be the world’s answer to the ever-growing plastic pollution. It is a common material used for packaging products in industrial and commercial operations. Kraft packaging is made from a renewable resource, which is biodegradable and recyclable. However, unlike regular paper, kraft paper can be made from any type of wood species.

During the kraft process, the natural wood is ground into a pulp and then treated with white liquor, which is a mixture of sodium hydroxide and sodium sulfide. It separates the lignin and the cellulose. Due to its reduced lignin and high sulfur content, kraft paper is very sturdy.

The kraft process is better for the environment, as it requires fewer chemicals, which can be recovered and reused without affecting the quality of the output.

Kraft has a natural brown color because of the wood pulp. Although it can be bleached, this process can weaken the fibers that make the material strong. The extra bleaching step can also drive up the manufacturing costs of the kraft packaging.

Kraft papers are arguably more sustainable and eco-friendly than regular paper materials. The kraft process is a self-sustaining method used to produce kraft papers and boards. Any type of wood can be used in this method, including pine and bamboo, which aren’t options for traditional paper making.

Since the kraft process results in lower lignin and higher sulfur content, kraft paper is sturdier than regular paper. It holds up well against heat, moisture, grease, and rough handling during shipping, making it a superior choice when it comes to packaging. It can be used to store food and beverage, cosmetics, appliances, and various other products.

Compared to general packaging materials such as plastic, kraft paper is more affordable. Despite its strength and thickness, it won’t add much weight to your package, allowing you to save on shipping costs.

The growing demand for kraft paper and eco-friendly packaging might further reduce their costs in the years to come.

Benefits of Kraft Paper Packaging

Why are so many businesses willing to switch to kraft paper boxes packaging? Aside from the rise in demand for sustainable packaging, using kraft has a range of advantages.

1. They Are Versatile

From envelopes and food-grade boxes to tuck-top kraft boxes and folding cartons, kraft paper can be turned into all kinds of packaging materials. No matter what type of product you sell, you’d have the option to use some form of kraft paper packaging.

If what you need isn’t available on the market, you can have custom packaging to fit your products.

2. They Are Durable

Kraft paper boxes packaging is very strong and robust. It can withstand rough handling and shuffling in transit, which enables brands to protect delicate products from damage.

Natural kraft paper lasts longer than its recycled alternatives because it mostly contains pure wood pulp. The raw materials are harvested from tree trunks and contain high concentrations of fiber. Recycled kraft paper will usually contain bark and other materials, which reduces its strength.

Although it’s durable, kraft tends to lose its strength when exposed to water. Thus, it’s usually treated with special resins when used to wrap wet products.

3. They Are Eco-Friendly

Kraft packaging reduces your carbon footprint because it is 100% eco-friendly. Even if it isn’t segregated in the trash, the kraft material will decompose in the landfill in a matter of weeks, leaving no negative impact on the environment.

Take note that kraft paper must be free from any plastic films and special resins if you want it to be 100% compostable. Let’s say you use kraft cut-out windows for your product packaging. Adding a non-compostable material, like a gloss lamination, over that cut-out space won’t make your packaging 100% eco-friendly.

Instead, you can leave that cut-out space open. Your customers can have a closer look at your products, while you stay true to your promise to deliver their goods in eco-friendly packaging only.

It’s also a recyclable material. You can recycle old kraft boxes and turn them into new packaging.

4. They Are Cost-Effective

Natural kraft paper is more affordable than plastic packaging. Even though they are sturdier than regular paper, their strength and durability don’t add to their weight. The kraft material won’t cost a lot of money in terms of shipping.

Buying kraft boxes wholesale can deliver a great deal of relief to a small or medium-sized business. The prices are significantly lower if you buy in bulk.

5. They Are Customizable

Paper kraft packaging can be manufactured in a variety of colors, dimensions, and shapes. Also, natural kraft paper is print-friendly. Using modern printing machinery, you can personalize your packaging in a variety of ways. You can print logos, attractive designs, and other product details directly on the material.

Custom kraft boxes with personalized prints usually cost extra money. If you want to personalize your boxes without spending too much, you can decorate them with stickers, ribbons, and stamps instead.

6. They Are Print-Friendly

As mentioned, kraft paper boxes packaging supports varying printing techniques, including digital printing and lithography. You may also use embossing and foil stamping techniques to enhance the look of your brown paper kraft boxes.

Whether you want to use soy-based or water-based ink, your prints will come out clearly on the kraft material. You can grab the attention of consumers and increase the promotions of your product.

Color Classifications of Kraft Paper Boxes

Kraft paper boxes have a natural brown hue. However, this natural hue can be turned into white and other colors through bleaching and other chemical processes.

1. Brown Kraft Paper

Natural kraft paper is dark brown with visible impurities on the surface. If you bleach kraft, you can reduce those impurities and brighten the color. However, you’ll reduce its strength in the process. Hence, for shipping boxes and outer layer packaging, which protect your products from dust and moisture, natural brown kraft paper is more ideal.

2. Black Kraft Paper

Black kraft paper has a smooth surface with a slight glossy sheen. It is used mostly as backdrop for picture frames because of its sleek and professional appearance. Sometimes, it’s used for bulletin boards, banners, and wrapping.

3. Bleached Kraft Paper

Naturally brown kraft paper can be bleached to produce a lighter color. This type of kraft paper is often used in the restaurant industry as a cost-friendly alternative to linen tablecloths. It can also be used as wrapping paper for packages.

Although the bleaching process may weaken the fibers that make kraft paper durable, there are other ways to lighten the material without affecting its strength.

4. Single-Sided Smooth Kraft Paper

This type of kraft paper has a smooth and bright side, which has minimal impurities. The other side has that brown hue that kraft paper is known for. It also has the impurities of natural kraft paper.

Types of Kraft Paper Packaging

There are different types of kraft paper packaging on the market. In general, these packaging materials are very sturdy. However, their strength and application may depend on the source of the wood as well as the manufacturing processes used.

1. Virgin Kraft Paper

Virgin kraft packing is made from raw wood pulp. This natural wood is harvested straight from the tree before it is manufactured into brown paper.

Even though virgin kraft paper isn’t very thick or heavy, it has high tear resistance and stiffness. It is an ideal packaging material for heavy-duty applications and is used to make packaging tapes, corrugated mailer boxes, and more.

The naturally brown hue of the kraft paper adds to its uniqueness, making it look rustic and homemade. Plus, unlike whiter packaging alternatives, the rough handling process isn’t as obvious on kraft paper boxes.

2. Recycled Kraft Paper

Coated recycled board is made of recycled content, such as cardboard boxes, books, and kraft materials. They are reduced into pulps before they are turned into recycled paper.

Once kraft paper is recycled, it won’t be as sturdy and tear-resistant as virgin kraft paper. It is great for products that don’t require high tear resistance like cereal boxes, paper bags, and paper cans.

3. Mixed Kraft Paper

Mixed kraft papers are used for postage boxes and cardboard envelopes. As its name suggests, mixed kraft paper is a blend of sorts. It contains recycled and virgin pulp, which makes it as sturdy as natural pulp. It’s cheaper and more eco-friendly because it contains recycled materials.

Kraft Paper Packaging Designs

What is kraft paper used for in packaging? Kraft paper boxes packaging is incredibly diverse. From bags to boxes, here are some unique packaging and gift box ideas that you can use with kraft materials.

1. Countertop Display

Businesses with brick-and-mortar shop locations use countertop displays to entice customers to buy more. At supermarkets, makeup stores, and confectionery shops, these are the little containers you’ll see at the counter. These kraft display boxes don’t take up a lot of space. They can hold several small-sized products, which are often very enticing.

With their eye-catching designs and styles, countertop boxes are meant to grab the attention of consumers while they’re checking out. They can also feature product-related information that may influence the purchasing decision of prospects.

2. Food-Grade Boxes

Kraft paper food packaging comes in a wide array of designs to fit a variety of food products. Salad containers, for instance, have at least one big clear window and side buckles to prevent your greens from spilling out.

Takeaway containers, like gable boxes and food bags, may have protective films like oil-proof lamination and heat-retaining coatings to keep the food fresh inside and prevent the grease from seeping into the paper. They may come with flaps that can be ripped out.

By using food-grade kraft boxes, restaurants and fast-food chains can reduce their plastic waste. They can reduce costs as well.

3. Paper Bags

A kraft paper gift bag may have greaseproof and waterproof finishes to accommodate homemade products such as greasy food and baked goods. Apart from the natural brown color, a paper bag of this type is available in a wide array of colors.

4. Magnetic Boxes

Built with magnetic flap closures, these kraft paper boxes look very sleek and luxurious. You can add custom foam or silk inserts to protect fragile products like porcelain figurines, silverware, and more. This extra step you take to include add-ons can elevate the appeal of your product and improve the brand experience.

5. Jewelry Packaging

For businesses selling handmade jewelry and accessories, kraft jewelry boxes are an affordable and creative way to ship your goods to customers. Adding a foam insert to your kraft box can help protect the delicate trinket inside.

You can have the traditional styles of jewelry boxes, which come with a solid lid that covers part of the base. If you’re willing to spend extra, you can have custom kraft boxes with clear lids. You can also use black kraft boxes. They have a sleek and simple natural look that seems timeless and premium.

6. Pop-Up Tubes

Unique product packaging can give you a distinct advantage in the market. It can get people talking. Pop-up tubes usually have two thermoformed lids that go on each side. Apart from giving the tube structure, the lids also help preserve the flavors of your candies, cookies, spices, and other treats.

7. Tube Packaging

Rigid kraft cardboard can be turned into tube packaging, which can be used to store t-shirts, jeans, and accessories. Its sturdy walls are great for protecting glass bottles like essential oils, cosmetics, and other products. For fragile goods, you can opt to add a foam insert to ensure that your glass bottles stay secure at all times.

Unlike your average folding box carton packaging, this rigid kraft cardboard tube will retain its shape no matter how rough it’s handled during shipment. They are long-lasting and reusable.

8. Cut-Out Window Boxes

Clear plastic windows won’t make your packaging 100% eco-friendly. Instead of adding a see-through plastic over your cut-out packaging, leave the window open. It gives your customers a glimpse of the product inside. It can be used to wrap lightweight products such as hair clips, phone accessories, and other tiny trinkets. It can also be used to secure more delicate products like scented candles, mugs, and wine glasses.

9. Resealable Pouches

Resealable pouches can be made with kraft paper, too. They are great for storing lightweight goods like loose teas, herbs, spices, and dried fruit. Like the food-grade boxes, they may have an optional clear window. Some may have aluminum foil included, which prevents moisture from seeping into the package.

10. Gift Boxes

Kraft gift boxes come in many shapes, sizes, and designs, such as kraft pillow boxes. These little containers form a curved pillow shape once you stash small gifts inside. A two-piece kraft gift box, on the other hand, has a lid that goes over and fits the tray tightly.

Bigger kraft gift boxes may contain inserts to divide and secure the products inside. Like other kraft packaging options, you’re free to customize them using creative prints to enhance the unboxing experience for customers.

11. Sliding Boxes

Sliding boxes can be used to hold a variety of products, including silverware, clothes, and accessories.

Retailers use kraft sliding boxes to give the customer a unique unboxing experience. If your box is designed to slide open from one side, you can attach a ribbon or a rope pull to the drawer so it’s easier for customers to open the box. An alternative would be a finger notch cut. You can add this to the side of the drawer that opens to ensure a fun and hassle-free unboxing experience.

12. Corrugated Shipping Boards

Kraft corrugated boxes are made of multiple layers of kraft paper. A corrugated board has two thicker outer layers called liner boards. Sandwiched between them is a thinner fluted corrugated sheet, which makes the board highly impact-resistant.
