1.Some parameters of 5-layer AB corrugated carton
- Name: AB corrugated 5-layer carton
- Color: brown, yellow-brown
- Quantity:~300LBS/m2
- Volume: Depends on material
- Size: According to customer request
- Paper Level:Custom
- Style: Regular cardboard
2. Structure
- In general, 5-layer cartons are made of two main types of paper. These are flat paper and corrugated paper stacked alternately to form a 5-layer carton paper product.
- The thickness of the AB corrugated layer is 8-9mm, very thick and sturdy. Ensures durability and contains both properties of wave A and wave B.
2.1 Flat layers of paper
2.1.1 Flat outer layer of paper
- This is the best quality paper of all. The material is Kraft paper with pure silkworm pulp containing a lot of lignin, making the paper more durable and difficult to tear.
- The quantity of this outer layer of paper is also very high, about 220 – 285LBS ensures paper standardity as well as paper surface uniformity.
- The paper on the outside of the carton is imported from Korea, Thailand or Taiwan, with a full factory certificate. Ensuring the reputation of carton products.
2.1.2 Middle layer of paper and inner layer of paper
- The middle layer of paper and the lining paper are usually of slightly poorer quality and are often not as smooth as the outer layer of paper to reduce production costs.
- However, if you want, you can still use a good layer of paper as the outside for specific products.
- The weight of the liner and middle layer of paper is usually around 135-185LBS. Still ensuring the necessary toughness for the inside of the carton.
2.2 Corrugated paper layer
2.2.1 Corrugated paper layer A
- Wave A has a height of mm with the ability to disperse force on the paper surface while helping to support the products packaged inside.
- Next is a layer of high corrugated paper that allows packages to be stacked on top of each other in large quantities. This means that the ability to withstand the compressive force of wave A is extremely good.
- A wave structure of AB 5-layer corrugated carton
2.2.2 Corrugated paper layer B
- Wave B is the opposite of wave A in that it has a lower wave height of about 2.5-3.2mm. The number of wavelengths above 30cm is 47 and the difference is 3 wavelengths.
- The toughness of corrugated paper layer B is very high, making it difficult to tear. This is the advantage of this layer of corrugated paper.
- B wave has a very high resistance to penetrating forces, so that forces from the outside will not penetrate inside.
2.2.3 Notes
- There is a very special feature that few people notice: these two wave layers are arranged according to rules. Corrugated paper layer A will be arranged on the inside and corrugated layer B on the outside.
- The reason for such arrangement also comes from the properties of these two types of waves. The external B wave can resist external forces and the A wave can help disperse the force from the product impacting onto the box wall.
3. Advantages of 5-layer AB carton
5-layer carton products have many outstanding advantages to help people use cartons with peace of mind and trust.
3.1 Thick, sturdy and very light
- The combination of two corrugated layers A and B helps increase the thickness of the carton, giving the carton boxes high rigidity, able to contain large products.
- The weight of 5-layer cardboard is also very light, they are only a little heavier than 3-layer products. So it's very easy to transport.
3.2 Able to protect objects most safely
- The combination of two corrugated layers A and B provides maximum penetration resistance while also helping to disperse impact forces on the barrel surface at the highest level. Therefore, the product that needs to be packaged will be absolutely safe.
- There is also the ability to stack multiple packages on top of each other for easy storage as well as easy transportation or export of goods.
3.3 Easy to reuse, recycle and safe for the surrounding environment
- In general, this is a common property that all cartons have, not just 5-layer AB corrugated cartons.
- A carton can be used many times and when it can no longer be reused, it will be brought to the factory and recycled.
- In case it is not recycled or accidentally left somewhere. Carton also easily decomposes when exposed to water or left in the environment for a long time.
3.4 Low cost
The cost of carton is generally much cheaper than other types of packaging. Investing in this product, customers will see that its price does not include all the features it brings.
