After dismantling the iPhone box, Japanese experts lament that Chinese kraft chocolate box packaging is difficult to surpass

1. Kraft chocolate box packaging companies need to challenge the most difficult box-making process:

For many kraft chocolate box packaging manufacturers, tens of millions of iPhone packaging boxes a year not only means huge profits, but also means that kraft chocolate box packaging companies need to challenge the most difficult box-making process.

After the dismantling of the iPhone series packaging box, Makoto Murakami, the president of the Murakami Paper Ware Industry Co., Ltd., which is engaged in the manufacture of micro-corrugated veneer paper boxes in Osaka, expressed his thoughts. "I've made a lot of kraft chocolate boxes in my life, but this is the first time I've seen a box with this structure. And it's hard to believe it right away with the production of tens of millions of them a year."

2. The difference between ordinary kraft chocolate box and IPhone packaging:

Murakami Paper Co., Ltd. is a factory that specializes in customizing kraft chocolate boxes according to customer requirements. From pastry boxes to kraft chocolate box packaging for high-end audio, the company has developed kraft chocolate boxes in different shapes and uses according to the special requirements of customers.

So, what is the kraft chocolate box that made the well-informed President Murakami exclaim "the first time"? "Nikkei Design" invited President Murakami and technicians engaged in the production of kraft chocolate boxes to disassemble and analyze the iPhone's packaging box with the help of many parties.

3. There are several limitations and features in the manufacture of kraft chocolate box:

The type of box used for the iPhone is a "veneer carton". It is a kraft chocolate box that uses corrugated paper and other cardboard as a base to make a frame, and pastes a thin layer of decorative paper on the surface.

Compared with the "plug-in carton" that can be folded with only a sheet of thick paper and corrugated paper, this kind of carton is more rigid and has higher precision. Moreover, by changing the decorative paper pasted on the surface, the texture and the impression of the box can be adjusted freely, and kraft chocolate boxes are mostly used in the packaging of domestic and foreign high-end brands such as pastries and jewelry for gifts.

However, due to the limitations of mechanical automation production, the cost of kraft chocolate box is high. Furthermore, there are several limitations and features in the manufacture of kraft chocolate boxes for structural reasons.

One is the "corner" of the kraft chocolate box. When making a frame with cardboard, the general kraft chocolate box goes through the following procedures (the following figure "structure of a general kraft chocolate box"). First make an indent on the heavy cardboard, then with the indent facing out, fold along the line and glue the decorative paper around the perimeter.

At this point, there are gaps between the folded corners as shown in the image below. As a result, no sharp corners are formed when the decorative paper is pasted on the periphery, giving the entire kraft chocolate box a rounded impression. The appearance is calm and solemn, like a wooden box whose corners have been polished with age.

4. The thicker the paper used in the kraft chocolate box, the less angular the corners will be:

That is to say, in order to express the rigidity of the kraft chocolate box, the thicker the paper used in the kraft chocolate box, the less angular the corners will be. But Apple won't allow that to happen. In Apple's view, packaging, as a carrier for the iPhone that thoroughly pursues a sharp impression and showing the characteristics of the product to customers, not only needs a strong sense of rigidity, but also must be as sharp as possible.

5. Bulgari chocolate kraft chocolate box:

To this end, Apple used a "V-cut" method of carving a 90-degree groove on the cardboard and folding it inward to form a right angle. V-shaped cutting is not only troublesome, but also requires high precision for processing, so it is very costly. As far as the reporter knows, among the kraft chocolate box packaging that adopts this processing method, the closest to daily life is a kraft chocolate box of Bulgari chocolate with a price of 1,500 yen (about RMB 97).

Based on the V-shaped cutting technique, Apple has undergone multiple improvements to make a simple and tough packaging
