What are the advantages and disadvantages of folding carton: in the process of packaging structure design, designers often choose different types of carton according to different needs. The common ones are tubular folding carton and disc folding carton. For the tubular folding carton, it is represented by the bottom lock buckle cover carton. The advantages of this kind of carton are as follows

1. The tool die is simple. Compared with the disc folding carton, the tubular folding carton does not have a large area of two surfaces overlapping, so there is no need to consider the allowance near the folding opening and indentation line. It should be noted that when the bottom is designed, it should ensure that there is enough extension allowance after the bottom is locked to ensure that the products in the box can be supported. At the same time, it takes less time to fold.   

2. Less consumables. Compared with the disc folding carton, the tubular folding carton has smaller surface area under the same volume, so there are relatively few consumables.  

3. The difference between internal and external dimensions is small. Because the front, rear, left and right sides of the tubular folding carton are mainly connected by latex paste, and there is no need to fold and fix the paper, the difference between its external size and internal size is small, which is generally 1.5 times the thickness of the paper sheet

The above are the advantages of the tubular folding carton. Its disadvantage is that the bottom is stacked with paper to support the product, so the product is easy to break when it is impacted up and down inside. At the same time, this packaging structure is more suitable for the box with little difference in length and width. In addition, the compression capacity of tubular folding carton is poor, and it can not be stacked in multiple layers. The advantages and disadvantages of disc folding carton and tube folding carton are just the opposite, and they are complementary. The representative type of disc folding carton is aircraft carton (because it is similar to aircraft pattern after unfolding), which has the disadvantages of complex knife mold, troublesome folding, relatively many consumables and large difference in internal and external dimensions; The advantage is that its bottom support force is large, and the product is not easy to break when moving up and down inside, which also determines that it has good transportation performance, so many express products use the packaging box with this structure; At the same time, the locking structure on both sides also ensures that the box has good compressive capacity and is suitable for multi-layer stacking

Whether it is a tube folding carton or a disc folding carton, designers should consider its advantages and disadvantages in the process of packaging structure design; At the same time, it is better to determine the proofing and carry out packaging test and verification for many times. At present, there are CNC cutting machines that can provide convenience for designers. No matter how complex the knife mold is, as long as the correct knife mold is drawn, the CNC cutting machine can quickly and accurately produce the template, which shortens the time of packaging design test and verification
