Materials of the packaging cartons

Packaging cartons are important tools for transporting and storing items. The choice of materials has an important impact on product protection and transportation costs. The following are the common packaging cartons materials on the market:

Corrugated cardboard

Corrugated cardboard is a composite material made of one or more layers of corrugated core paper sandwiched between two layers of surface paper，which is produced by corrugated cardboard production line. It is currently the most widely used carton material. It has the following advantages:

1. Light weight: The density of corrugated cardboard is small and light, which can effectively reduce transportation costs.
2. High strength: The structure of corrugated cardboard is reasonable, with high resistance to compression, impact and puncture, and can withstand large external impact.
3. Good cushioning: The wavy structure of corrugated cardboard can effectively absorb and disperse impact force, protecting internal items from damage.
4. Easy to process and shape: Corrugated cardboard can be processed into cartons of various shapes and sizes as needed to meet different packaging needs.
5. Recyclable: Corrugated cardboard is a recyclable material that meets environmental protection requirements.

The disadvantages of corrugated cardboard are:

1. Strong water absorption: Corrugated cardboard is easy to soften and deform after contact with water, reducing its strength.
2. Not resistant to moisture: In a humid environment, corrugated cardboard is prone to moisture and mold, affecting its service life.

Kraft paperboard

Kraft paperboard is made of kraft paper or boxboard as the outer fabric and corrugated paper as the core paper. It has the following advantages:

1. High strength:Kraft paperboard is stronger than corrugated paperboard and can withstand greater external impact.
2. Breakage resistance:Kraft paperboard has high tear resistance and is not easy to break.
3. Puncture resistance:Kraft paperboard has high puncture resistance and is not easily pierced by sharp objects.
4. Wear resistance:Kraft paperboard has high wear resistance and the surface is not easy to wear.

The disadvantages of kraft paperboard are:

1. High cost:The raw material cost of kraft paperboard is high, so the price is also higher than that of corrugated paperboard.

Composite processed cardboard

Composite processed cardboard is made on the basis of corrugated cardboard through plastic coating, laminating, aluminum foil pasting, embossing and other processing. It has the following advantages:

1. Beautiful appearance:The surface of the composite processed cardboard has been processed and has a beautiful appearance, which can enhance the product image.
2. Moisture-proof:The composite processed cardboard treated with plastic coating or laminating has good moisture-proof performance and can protect the internal items from moisture.
3. Oil-proof:The composite processed cardboard treated with plastic coating or laminating has good oil-proof performance and can protect the internal items from oil pollution.
4. Anti-corrosion:The composite processed cardboard treated with aluminum foil has good anti-corrosion performance and can protect the internal items from corrosion.

The disadvantages of composite processed cardboard are:

1. High cost:The processing cost of composite processed cardboard is high, so the price is also higher than corrugated cardboard and kraft cardboard.
2. Not environmentally friendly:Some materials of composite processed cardboard, such as aluminum foil, are difficult to recycle, so it causes certain pollution to the environment.

Honeycomb cardboard

Honeycomb cardboard is made of one or more layers of honeycomb paper core sandwiched between two layers of paper. It has the following advantages:

1. Lightweight:Honeycomb cardboard has a low density and light weight, which can effectively reduce transportation costs.
2. High strength:Honeycomb cardboard has a reasonable structure, has high compression resistance, impact resistance and puncture resistance, and can withstand large external impact.
3. Sound absorption:The honeycomb structure of honeycomb cardboard has good sound absorption effect and can reduce noise.
4. Heat insulation:The honeycomb structure of honeycomb cardboard has good heat insulation effect and can maintain the temperature of internal items.
5. Good cushioning:The honeycomb structure of honeycomb cardboard can effectively absorb and disperse impact force and protect internal items from damage.

The disadvantages of honeycomb cardboard are:

1. High cost:The production process of honeycomb cardboard is complicated, so the price is also higher than corrugated cardboard, kraft cardboard and composite processed cardboard.

How to choose the right packaging cartons material？

When choosing the material of the packaging cartons, you need to consider it according to the specific situation of the product. Here are some suggestions:

1. If the product is light in weight, you can choose a corrugated cardboard box.
2. If the product has high strength requirements, you can choose a kraft cardboard box.
3. If the product needs to be moisture-proof, oil-proof, and anti-corrosion, you can choose a composite processed cardboard box.
4. If the product has high environmental requirements, you can choose a honeycomb cardboard box.

Here are some common types of corrugated cardboard:

1. A-type corrugated cardboard: A-type corrugated cardboard is made of a layer of corrugated core paper sandwiched between two layers of surface paper. It has good cushioning properties and is suitable for packaging fragile items.
2. B-type corrugated cardboard: B-type corrugated cardboard is made of two layers of corrugated core paper sandwiched between two layers of surface paper. It has high strength and rigidity and is suitable for packaging items with heavy weight.
3. C-type corrugated cardboard: C-type corrugated cardboard is made of three layers of corrugated core paper sandwiched between two layers of surface paper. It has the highest strength and rigidity and is suitable for packaging very heavy or irregularly shaped items.

When choosing corrugated paperboard, you also need to consider the following factors:

1. Corrugated paper thickness: The thicker the corrugated paper, the higher the strength and rigidity of the carton.
2. Corrugated paper height: The higher the corrugated paper height, the better the cushioning of the carton.
3. Corrugated paper direction: The direction of corrugated paper can be vertical or horizontal. Corrugated paper in the vertical direction has higher strength and rigidity, while corrugated paper in the horizontal direction has better cushioning.

Hope the above information about the materials of packaging cartons is helpful to you.
