What are corrugated boxes
Corrugated cardboard box is the most widely used type of packaging, it is a multi-layer adhesive body, which consists of at least one layer of wavy core paper sandwich and a layer of cardboard.
Such the structure has high mechanical strength, good compressive strength and shockproof performance, but also can withstand the handling process of collision, impact and fall. Thus gradually replaced the wooden box transportation. In addition to protecting goods, easy storage, transportation, but also play a beautifying and promotional role.
The pros and cons of corrugated boxes
Corrugated cardboard boxes have become the mainstream packaging materials with the advantages of lightweight, low cost, good cushioning performance and environmental protection, but in the moisture-proof, waterproof performance is poor.
Advantages:
- Good shock absorption and shock absorbing ability, this can effectively protect the goods from damage.
- Space saving. It can be folded into a flatbed, reducing the size of the shipment and thus reducing shipping costs.
- Good printing effect. Excellent ink absorption on the surface, easy to print and publicize.
Disadvantages:
- Poor moisture resistance. Easily softened by moisture, the carton hardness and strength will be reduced over time.
- Poor waterproof and moldproof performance. It is sensitive to moisture and prone to mold and deterioration.
Corrugated storage boxes warning symbol set
Warning labels refer to the various warning labels affixed to corrugated carton packages, which usually include the right 5 categories:
- Choking Warning: If it contains a plastic bag larger than 5 inches, it must be labeled with a choking warning to alert children and prevent danger.
- Handling symbols: such as “up”, “use care”, “protect from moisture”, “no stacking”, “do not stack”, “do not stack”, “do not stack”, “do not stack”, “do not stack”, etc., guide proper handling and storage. ” to guide proper handling and storage.
- Labeling of chemical substances: If the package contains hazardous chemical stuffs, they need to be clearly indicated to inform consumers.
- Packaging material marking: recycling symbol, plastic type code, etc.
- Barcode labels: used for code scanning to facilitate logistics tracking and inventory management.
Joints are the key part of the corrugated carton box parts connection, common joints are mainly the following 3 kinds. Learn more details from here.
- Glued joint: The most used type of joint is to apply adhesive. The glued width is based on the layer numbers of corrugated board. The width of the single board joint is 25~45mm, while the multi-corrugated board joint is slightly wider, thus ensuring the strength and sealing of the box.
- Sewing Seam: Through the sewing machine, the joints of the carton are sewn with threads to enhance the strength and durability of the carton, which is commonly used for heavy-duty corrugated cartons.
- Short board joints: Shorter boards are spliced into corrugated boxes, but with more joints for larger packages. The joints of shortboard cartons also rely on gluing or stitching, which ultimately ensures overall stability.

The difference between corrugated and cardboard boxes is mainly in structure, strength and use:
- Structure: The cardboard box refers to a single layer of thick cardboard, a flat sheet of pulpboard with no internal structure. The corrugated box consists of 3 layers: 2 layers of flat cardboard and a corrugated core paper in the middle.
- Durability: Corrugated cardboard boxes are much stronger than ordinary cardboard boxes due to their multi-layer structure and corrugated core paper composition. The former is commonly used for fragile or heavier items, while the latter is used for lightweight packaging or display.
- Usage: Cardboard boxes are mostly used for lightweight packaging and product display. Corrugated cardboard boxes, on the other hand, are the most commonly used boxes in transportation, warehousing and logistics, and can effectively protect the safety of goods.
What is the difference between corrugated and cardboard box?
What are corrugated packaging box benefits?
- Good cushioning performance. Corrugated cardboard box consists of wavy corrugated in the middle, thus forming a hollow structure of about 60%, which can effectively prevent goods from avoiding shaking and impact during transportation.
- Light weight. For the same size, corrugated boxes weigh only 1.5 times as much as wooden boxes, making them easy to handle and store.
- Low cost. Corrugated cardboard is mostly processed from grass pulp, wood pulp or recycled waste cartons, and the raw materials are abundant and easily available. It is half the price of a wooden box of the same volume.
- Wide range of applications. Whether you use it for shipping, wine, gift or storage, XiangGe is the best maker for your customized corrugated boxes.
- Environmentally friendly and recyclable. Corrugated cardboard boxes can be reused and recycled many times, in line with environmental standards, and will not cause pollution to the environment.
At XiangGe, we know your product needs a strong box. That’s why we check every detail before it leaves our factory. Here’s how we make sure our corrugated boxes are strong, clean, and ready for shipping.
1. We Start with Good Paper
We choose high-quality kraft paper for every box. If the paper is too soft or thin, we don’t use it.
We match the right paper to your needs—strong for shipping, smooth for printing.
2. We Check the Flute
Flute is the wavy part inside the box. It gives the box its strength. We check the size and shape of the flute to make sure it fits your order. If the flute is crushed or not shaped well, we reject it.
3. We Look at the Box Surface
We check every box including: smooth surface, no bubbles, no wrinkles, clean printing, no smudge. If it doesn’t look good, it doesn’t pass.
4. We Do a Pressure Test
We press the box from the sides and top. If it dents too easily, it’s not strong enough. We also use machines to test the edge crush strength and burst strength. That’s how we know the box can handle stacking, shipping, and long trips.
5. We Test the Glue. We check if the box holds tight where it’s glued or stitched. If the corners open or the seam is loose, we fix it or toss it. Our team checks this by hand and with machines.
6. We Check for Moisture Protection (If needed)
Some customers need water-resistant boxes. We test by dropping water on the surface.
How does XiangGe Package produce corrugated boxes
We at XiangGe Package have fully automated or semi-automated production lines for different packaging orders and printing requirements. Below is the main process flow of our corrugated box production:
- Raw paper preparation: Procurement of face paper, core paper and spacer paper, etc. They are the main materials for production.
- Corrugated cardboard production: The core paper is processed into wavy corrugated paper and bonded to the face paper by adhesive to form single-sided corrugated paper. Subsequently, it is further bonded with the center divider paper to make multi-layer corrugated board.
- Cutting and drying: The corrugated cardboard is cut and the paper dust is blown away by a fan to ensure that the surface is clean. Then it is heated and dried to maintain a moisture content of 9% to 12%.
- Creasing and slotting: After being creased by the longitudinal and transverse creasing machine, it then enters the printing machine for slotting, thus being able to prevent the cardboard from tearing and ensure the quality.
- Printing and Coating: Printing the designed pattern in the printing machine, then coated with wear-resistant oil, and further drying to make the ink and coating dry, to ensure that the printed content is clearly visible and wear-resistant.
- Forming and gluing: Enter the carton forming machine for sidewall gluing, or nailer for sidewall nailing to form the basic structure of the carton.
- Packaging and Quality Inspection: After molding, the corrugated cartons go through the packaging machine to complete the final packaging. Throughout the production process, our QC department will strictly check each process and conduct grammage, edge pressure and breakage resistance tests to ensure that the products meet customer requirements.
