Leading Corrugated Box Manufacturers and Suppliers
Corrugated boxes are a type of container used in shipping and storage that are ubiquitous across thousands of industries. Although people often refer to them erroneously as cardboard boxes, they are made of corrugated materials. Most typically the corrugated–meaning fluted, rippled or ridged—material from which they are made is corrugated fiberboard. This consists of two flat sheets sandwiched above and below a corrugated sheet in layers. Read More…
Corrugated Box ManufacturersCorrugated boxes are storage and shipping containers that are constructed of corrugated materials. The term corrugated material refers to material (usually a type of paperboard) that is rippled, fluted or ridged. Corrugated containers are usually composed of a corrugated fiberboard, a common form of material that consists of a corrugated sheet sandwiched between layers of flat sheets. Despite the inaccuracy of the term, “cardboard box” is widely used to refer to this type of container.

Because of their long life, strength and durability, corrugated boxes are the preferred container in shipping and storage applications. They are also used to organize materials in the short term, as in offices, homes and mail delivery. The corrugation process strengthens these fiberboard containers while maintaining very low weight.
Because of their affordability, low weight and strength, people come across corrugated boxes in many applications every day. They are used to store and ship many consumer products, and as packaging for products from toothpaste and cereal to computer paper and soap. Oftentimes with consumer products like these, the corrugated containers have a shiny, wax-like finish applied, with company logos, brand names and graphics added to the packaging. Retail clothing store boxes, jewelry boxes, gift boxes, pizza boxes and containers for baked goods and cakes are all made of corrugated paper materials.
Some of the countless industries that rely on corrugated containers every day include auto parts, hardware, tools, food processing, health care, construction, toys, publishing and restaurants, to name just a few.
History of Corrugated Boxes
Corrugated paper materials have been used as packaging for over 150 years. Before that time, paper products were simply too expensive due to the laborious processes by which they were made, most often by hand. With the advent of industrial processing techniques of wood pulp, paper packaging materials became more and more affordable and widely used. This occurred in the mid 19th century during the Industrial Revolution.
In the mid-1850s, a patent was issued in the United Kingdom for the first corrugated paper; this was used to line hats. Over a decade later an American, Albert Jones, received a patent for the first corrugated board. This board, developed in the early 1870s, had just a single face, unlike the ubiquitous three-layer corrugated fiberboard in use today. It was the first such material used for shipping. Building upon Jones’ design, the inventor Oliver Long developed, in 1874, corrugated fiberboard with two flat faces around a central layer of corrugated fiberboard. In the same year G. Smyth invented the very first industrial corrugator machine that could mass-produce these materials.
The type of corrugated shipping boxes used today, and the materials from which they are made, were not fully developed until the late 1800s and early 1900s. Swedish chemist and inventor Carl Dahl used, in 1884, pulverized wood chips to create a strong product known as kraft paper, which was also resistant to tearing. By the early 20th century manufacturers were producing kraft paper on a regular basis. But still, corrugated shipping boxes as we now know them were not developed until a New York printer named Robert Gair, in 1890, accidentally stumbled upon a way to make them. Gair discovered the process when a tool meant to crease paper seed bags malfunctioned and cut the bags instead.
At first corrugated boxes were mainly used to package fragile items such as ceramics, glass products and the like. But in time, more and more products, such as produce from farms, came to be shipped in corrugated fiberboard containers. By the 1990s, in the U.S. alone, manufacturers produced 25 million tons of corrugated fiberboard. Paper, once an expensive and hardly used material, had become widespread because of its affordability, strength and durability.
How Corrugated Boxes Are Made
Today, corrugated boxes are typically made from kraft paper, a high quality paperboard derived from wood. When an even stronger container is required they can be made from corrugated plastic.
Paper mills and corrugating plants, respectively, produce kraft paper and corrugated boxes, separately. This allows for maximum efficiency. To make kraft paper, mills use recycled paper, sawdust and wood chips, which are bound together to produce heavy-duty paper using an adhesive, pressure and heat.
Pine trees are the raw materials used to manufacture kraft paper and corrugated boxes. Therefore, many large manufacturers own not only paper mills, but also vast tracts of pine forest consisting of hundreds or thousands of acres.
In the mills, pine trunks that have had their branches cut off are stripped of bark and cut into small wood chips, then undergo a chemical process known as the kraft process or sulfate process. At this stage the chips are turned into fibrous pulp by “cooking” in an alkaline solution made primarily of sodium hydroxide. Next the pulp is dehydrated in Fourdrinier machines, turning it into paper. Finally, the paper mills output reels of kraft paper, which are shipped to corrugating plants and stored as inventory.
Manufacturers use huge machines called corrugators, which can be 300 feet long, to corrugate the kraft paper. First, these machines soften the kraft paper in preheating rollers at high pressure and humidity, making it easier to form the flutes or ripples. Then corrugated molds are pressed into the cardboard to form the fluted board. Two glue stations next join this newly corrugated material to the outer flat layers using a corn starch-based adhesive, making a complete piece of corrugated fiberboard. After drying this material over hot, steamy pates, the surface may be sanded smooth and in some cases coated with a waterproof, glossy finish. Finally, the massive corrugator machine divides the continuous fiberboard into box blanks, large sheets ready to be cut into different sizes. Many of the corrugator machines manufacturers use can produce 500 feet per minute of corrugated fiberboard.
The sides of corrugated boxes are composed of layers of materials: an inner layer, a middle layer, and an outer layer. The middle layer is fluted with wave-shaped arches that act as support and cushioning for the materials inside the box.
Box making machines then produce actual containers or boxes from this corrugated fiberboard, which are sold typically in bulk bundles of 20-50 or more. To save space during shipping the bundled boxes are sold flat rather than assembled into box form.
These durable fiberboard boxes are used by many industries.
Types of Boxes and Corrugated Fiberboard
Though technical differences exist between them, people often use the terms corrugated material, cardboard and paperboard interchangeably. People in the packaging and shipping industries tend to avoid using the word cardboard, a generic term that can refer to any heavy material made from paper pulp, because it is imprecise.
Along the same lines, paperboard technically means heavy wood- or paper-based material that is generally thicker than regular sheet paper. Another term, chipboard, is a bit moreprecise. It refers to recycled paper that has been pressed to a certain thickness; many light items such as cereal and board games are packaged in boxes made from chipboard.
Corrugated fiberboard refers to the three-layered kraft paper most commonly used to produce corrugated boxes. By definition corrugatedhere means containing pleats or ripples, known in the industry as flutes. Like pleats, these ripples contain air, which makes these boxes more durable and provides a cushion for anything stored or shipped within them.
Both the types of corrugated fiberboard and the types of boxes made can be customized depending on the end use of the container or box. Flute size, materials used to make the box and binding adhesives all vary. With smaller flutes or pleats, there is better structural integrity and more room for marketing text. Larger flute sizes, on the other hand, offer more cushioning for the contents of the box. The number of flutes and their sizes affect variables like board thickness, cushioning strength and compression strength. Within a single container or box flute sizes and spacing can vary as well.
The size, shape, lids, finishes and ways of closing containers all vary too. Box shapes include square, rectangular and cylindrical, though boxes can be custom manufactured to fit virtually any object. Die cutting machines use either a sharp metal blade or laser to cut boxes into unusual shapes. They may have a detachable lid or be made of a single piece of fiberboard with flaps that fold. End users assemble each box by folding the flat board when ready for a specific use. Some containers are held together by tape or other fasteners, while folding boxes require no tape—folded flaps hold the assembled box in place.
Custom-made boxes used for shipping, storage and organization may have dividers, text and images printed on them, be waxed, or come in a variety of finishes. For commercial products such as soap, cereal and toothpaste, manufacturers make corrugated boxes with a glossy, laminated finish printed with brand names, logos and information. Bleaching or mottling the exterior of the corrugated fiberboard produces white cardboard boxes by removing the dark brown pigment. These and natural brown boxes are the most commonly used.
Corrugated Box Benefits
There are many advantages to using corrugated boxes and containers. They: can be recycled; are inexpensive and lightweight; are durable and versatile; are a reliable way to ship goods and protect them in transit; and they provide an ideal surface on which to print text and graphics.
There are, however, downsides to corrugated boxes. These containers cannot be used to ship heavier items, and in some industries where sanitary concerns are paramount, such as medical supplies and hospital food storage, fear of contamination from insect infestation and liquid absorption preclude the use of corrugated fiberboard containers.
Corrugated Boxes: Packaging Solutions for Startups
Lockdowns and social-distancing norms set off a surge in online shopping. Many startups who wish to take advantage of this trend turn to boxes and paper bags to deliver their products. This packaging not only serves as protection but also as branding, establishing trust between consumer and producer. Proper packaging design helps build an identity for a product.
Aside from branding, startups also need to consider the cost of their packaging. Design, materials, and the structure of your packages play a key role in their affordability. Business owners also need to consider the availability of their packages; ordering in bulk allows owners to reduce the cost of their packaging needs. Choosing the right supplier with a reasonable and affordable minimum order requirement can go a long way in helping your startup business grow.
Food Industry – Corrugated boxes are made from natural materials. The glue used to connect their parts is made from starch and water. These boxes also protect contents from bacteria, keeping foods fresher longer.
E-commerce – Rising global demands for convenient and lightweight packaging solutions have made corrugated boxes an irreplaceable asset in the e-commerce industry. They offer security and safety for the many products that pass through far-off trade routes and supply chains.
Electronics – Electronics and electronic components need to be handled with care. Corrugated boxes can be supplemented with protective packaging materials to keep these types of items from damage, thanks to the cushioning provided by their fluted layers.
Textile – The textile industry is very reliant on branding to ensure that customers will return to purchase their products. Corrugated boxes allow manufacturers to design and personalize their packaging to attract and retain customers.
Consumers care now more than ever for sustainability and brand values in their products. The importance of thoroughly planning the packaging of your products cannot be underemphasized. Choosing the right kind of packaging will significantly help the presentation and identity of your products.
Care, Safety and Compliance Standards of Corrugated Boxes
Keeping corrugated containers dry is essential to maintain their strength and durability, as moisture undermines these fundamental properties. Also, like wood that is easier to split along the grain, corrugated boxes made of fiberboard are directionally dependent or anisotropic. They will not function properly if handled in a manner inconsistent with their intended anisotropy or directionality.
U.S.-based ASTM International sets the technical standards governing the corrugated packaging industry. These standards assess properties of corrugated fiberboard and the products made from it, such as tear resistance, weight limits and breaking strength, as well as setting industry standard practices for fiberboard and box construction and for closing and sealing shipping and storage boxes safely.
Things to Consider/Choosing the Right Corrugated Box Manufacturer
In the United States alone, there are more than 1,000 manufacturers of corrugated boxes and similar containers. It is therefore key to find the right one for your specific needs. Discuss with potential suppliers: whether they have been certified; their compliance with the aforementioned ASTM International standards; manufacturing timelines; how they will ship your boxes to you; the end use for which you need the products; and if they are able to develop the custom solutions you need, such as printing text and graphics on the containers, any unusual shapes or sizes you may need, dividers and custom finishes such as waxed corrugated boxes.
Additional things to consider include whether the packaging will enhance your company’s brand; whether you should measure the container internally (for shipping products to customers) or externally (for in-house uses); container strength (which is based on the grade of kraft paper used to manufacture the container); and the level of product security you require.
Corrugated Box Terms
Box Plants – A factory that produces corrugated and/or cardboard boxes.
Cardboard – Any heavy paper-pulp based board. Cardboard is not necessarily corrugated. To be “corrugated”, board must have fluted paper with air pockets in the middle of its outer layers.
Cardboard Bins – Cardboard containers that are usually trapezoidal or rectangular and do not include a lid.
Cardboard Storage Boxes – Cardboard containers that are used for storage purposes.
Converting Machines – Convert flat corrugated boards into boxes. Machine types may include flexfolder gluers and die cutters.
Corragated Boxes – A misspelling of “corrugated boxes,” containers made of a corrugated material.
Corrugated Cartons – Corrugated containers, many of which are specially designed to fit a specific product.
Corrugated Paperboard – Two sheets of stiff paper joined by a middle sheet of pleated paper.
Corrugated Trays – Often used for display purposes or used with a shrink-wrap covering.
Corrugating Medium – The wavy “fluted” paper inside the corrugated paperboard.
Corrugating Rolls – Gear-like cylinders that shape paper into a series of waves or “flutes”.
Die-cut Machines – These are machines that cut the corrugated board into a pattern that will later be folded into a box shape.
Five Panel Folder Boxes – Shipped flat without any folding joints. The box has five long panels, one of which fully overlaps. The ends also fully overlap.
