The heaven and earth cover box is an important classification in paper packaging . Although it has only a simple independent canopy and floor structure, the structural advantages of the lid separation greatly meet the packaging and transportation needs. Moreover, the Tiandi cover box has the advantages of high production efficiency, low cost and automatic mass production, and is currently favored by many high-end brands.
But the seemingly simple world of the box, but there is "professionalism." On the one hand, it is material selection. Most of the packaging materials used by our company are corrugated paper. This material has good compressive strength and shock resistance. It can withstand certain pressure, impact and vibration. It is not only low cost, but also environmentally friendly, suitable for printing production. In the view of the head office Stora Enso, wood fiber-based renewable materials can replace petroleum and become the packaging solution for the future world. On the other hand, it is also very important to focus on the design and production of the high-quality packaging box. Compared with our peers, our company focuses on the design and production of Tiandi cover boxes in areas with high product technology and high quality requirements, such as electronic products. These products mainly use miniature corrugated cardboard gift boxes and gray cardboard gift boxes. The perfect design of the heaven and earth cover box makes it look like a handicraft, that is, it needs to be meticulously carved and perfect, and also consider the different usage habits of different consumers. If the box cover is too rough and loose, it will not bring good protection to the goods, and even cause damage to the goods; if it is not guaranteed to open the package in a short time (for example, some mobile phone brands require the mobile phone package to slide open within 3 to 5 seconds) ), for the user, it means a bad open box experience. More importantly, the production of the Tiandi cover box should also consider how to combine different surface treatment processes on different materials to present more complex and exquisite craftsmanship (such as light, film, relief, hollow, hot stamping, refraction). , ice, frosting, wrinkles, foaming, etc.).
Over the years, our company has cooperated with many well-known brands. They have designed the appearance and details of the packaging box very seriously. The requirements for packaging materials and adhesives are also very high, and it is required to ensure a smooth and beautiful overall. The effect, which puts high demands on the precision, efficiency and manual operation level of our company's production equipment. Under the advancement of market demand, combined with the continuous improvement of practice, we have developed the "excellent martial arts" on the packaging box of our company. The three well-known brand mobile phone cover boxes described by the author below are sufficient.
Hammer mobile phone ingenuity throughout
Speaking of the application case, the company is most proud of helping the Smartisan T1 smartphone of Beijing Hammer Digital Technology Co., Ltd. (hereinafter referred to as "Hammer Technology") to win the iF Design Gold Award. This is the first time that the first smartphone in mainland China has been awarded the international design award known as “Oscar in the product design industryâ€. The jury of the Grand Prix commented: “This smartphone contains many thoughtful design details. There are subtle new features, all of which are contained in a complete and consistent product concept, which fascinates us. From packaging to the product itself, the ingenuity is always in the whole. Overall, the most convincing thing about this phone is its Ease of use and high quality design and completion."
The cover of the Smartisan T1 mobile phone case (shown in Figure 1) is made of recyclable black cardboard, which saves printing costs. The low-key, restrained, and distinguished black packaging cartons and mobile phones pursue perfection and contrast, focusing consumers' attention on the details of the box. The production of this heaven and earth cover box is the biggest test for the production plant. In addition to the technology, it is more from the management of details. Our company has perfected these details with professional technology and rich experience. The corners of the box are designed to be impeccable, and there are no quality problems such as dust, paper wrinkles, and wiping. "Hands carefully touch the box, psychologically have a subtle feeling, let you have unlimited expectations of the phone inside."

Nut mobile phone is so beautiful that even the packaging wants to collect
The nut phone with a lot of fans (a smartphone from Hammer Technology) has a total of 7 different color versions. No matter which color version of the back cover, the color is almost the same as the color of the back cover printed on the box. The details were drawn from the packaging team behind it – Stora Enso Zhengyuan Packaging Co., Ltd.
In addition to the exquisite and simple visual effect, the nut mobile phone's heaven and earth cover box (shown in Figure 2) also provides consumers with a great experience, that is, the nut phone world cover box successfully achieved "3 ~ 5 seconds slip The miracle of opening is a serious challenge for packaging manufacturers because of the high requirements for packaging materials and production processes. The nut mobile phone cover box is made of high-grade double-copper paper (double copper paper from Stora Enso Suzhou Zixing factory, environmentally-friendly renewable material certified by FSC forest) and high-gloss gray board paper. One detail that has to be mentioned is that the team of Luo Yonghao (the founder of Hammer Technology) who insists on “feelings†does not allow the traces of hand-made tape to appear after the box is slid open. This is also a requirement that other mobile phone brands have never proposed. After several trials, when it was almost abandoned, a turning point appeared. Our technical team developed a unique setting technology to avoid scratches when the box slipped out, and used semi-automatic instead of hand-made. , the production efficiency is higher and the quality is more stable.

Packaging is the coat of the brand, and the Luo Yonghao team, which attaches great importance to the reputation of the product, is cautious about the screening of packaging suppliers. Our company finally realized the high-quality delivery of the nut mobile phone “even the packaging is worth collectingâ€.
