Miniature Corrugated: Deductive Perfection

Editor's note: In recent years, new miniature corrugated cardboard has emerged in the Chinese market, and it has increasingly attracted the attention of people in the industry. It has been predicted that micro-corrugated cardboard may replace most of the folded cardboard for packaging, and the end-user industry in China also pays full attention to the application of micro-corrugated packaging.

In the packaging market, micro-corrugated paper is very popular. With its unique structure, high-strength seismic performance, exquisite printing, and low cost, it has been highly praised by users of household appliances, food, mobile phones, chemicals, and electronic products.

Corrugated board according to the needs of the market, its strength, stiffness, cushioning, etc. can be divided into different specifications, the most common market is A, B, C, E and other types. Its excellent performance, very stiff, with high mechanical strength, pressure, good bending, resistance to deformation and the ability to maintain the original shape.

High compressive strength: In terms of the characteristics of the corrugated paper itself, the micro-corrugated board has a higher compressive strength than a normal solid box at the same grammage. Therefore, according to their characteristics, people can combine different types of enamels according to different uses, and process and manufacture different packaging products to package products of different weights, types, and grades. For users who have higher requirements on the compressive strength of packaging, using microwatt packaging is an ideal choice.

Good cushioning performance: the use of micro-corrugated cardboard as the inner lining to replace the traditional buffer material, both environmental protection and can increase the compressive strength, is an ideal buffer material. Now, many perfumes, cosmetics and other products are lined with fine corrugated cardboard, which not only improves the compressive strength of the package, but also improves the grade of the package. Many digital and small home appliances are lined with micro-corrugated cardboard to replace traditional EPE, EPS and other buffer materials. Due to the formation of fine corrugated sheets and the selection of high-strength corrugated base paper, the cost is lower and more environmentally friendly. In a sense, corrugated paper products are easily recycled and recycled and are an ideal "green packaging" material.

The printing effect is good: in the past, the traditional corrugated corrugated cardboard can only be printed on the intaglio plate. It is not possible to directly print high-definition pictures such as photos. The compression deformation will destroy the strength of the cardboard, greatly affecting the printing accuracy and stability. Sex, can easily cause cardboard deviation, uneven thickness, affecting the printing speed synchronization, resulting in blurred patterns, causing great unnecessary waste. The micro-corrugated cardboard can be directly printed on the offset printing, which can not only obtain fine patterns, but also can not deform the corrugated paper due to printing, and reduce or destroy the strength of the cardboard. Offset direct printing makes the fine corrugated packaging printing more exquisite, highly displayable and advertising, and greatly improves the packaging quality. Therefore, more and more industries have begun to use fine corrugated packaging as sales packaging. In addition to the traditional food, toys, and home appliances industries, industries such as handicrafts, medicines and health products that require external packaging and gifts have also begun to use micro-tiles. package.

High quality and light weight: light weight and cost saving are another major advantage of miniature corrugated packaging. It is understood that some manufacturing enterprises have replaced E-cardboards with B楞, C楞 and other single corrugated paperboards in the past, and their packaging not only meets the requirements for safe transportation of the original products, but also can reasonably reduce packaging materials and transportation costs each year. . The exquisite printing effect of mini-corrugated cardboard makes it a better choice for making display-type corrugated cardboard display racks and other display packaging. In foreign countries, due to the high precision of die-cutting of the mechanical equipment itself, in the production of poster-type corrugated cardboard display racks, a large number of fine paperboards such as C楞, N楞, and F楞 have been used in place of traditional PVC sheets to make the entire poster-type corrugated cardboard display stand. Lighter weight, lower cost, not only easy to transport, but also easy to recycle.

Based on the characteristics of miniature corrugated and market demand, we will focus on the packaging market and the application of miniature corrugated products by typical enterprises over the past few years. We will talk about the technological challenges of micro-technologies and talk about the application of micro-technologies in domestic and foreign markets. prospect.

Typical application of miniature corrugated packaging

The advantages of fine corrugated boxes are getting more and more attention and are widely used in mobile phones, digital products, home appliances, food, medical equipment and other packaging:
★ Miniature corrugated has always been the first choice for mobile phone packaging. For example, Motorola's mobile phone products have always been used in carton packs of E or F.
★ Micro-tiles in digital products have also been favored. Such as Sony's CD-ROM drive;
★ Miniature corrugated or new darling of small appliances. Such as Kelon's 6-inch, 8-inch refrigerators and other small household electrical appliances;
★ The food industry is one of the largest users of corrugated paper products. Ruhe Snow (China) Co., Ltd. adopted F楞 carton;
★ Medical equipment is also a large user of micro-tiles. For example, the pacemakers of Medtronic (China) Co., Ltd. were applied to miniature corrugations.
★ In addition to mobile phones, digital products, food, medical devices and other fields, micro-watts are also used in the pharmaceutical, health care products market, as well as footwear, chemical products, electronic calculators and other small product packaging markets. In short, micro-corrugated cardboard or cardboard, instead of A, B, and C, is used as an outer packaging for small items, or is used in large items, and serves as a medium for lining, or for making advertising display stands and posters. The market is gradually expanding.

Miniature corrugated technology
Miniature corrugated cardboard has added new functions on the basis of inheriting the functions of the above ordinary corrugated board. Compared with the same type of traditional fiber cardboard, micro-corrugated cardboard has the following advantages: material saving, good elasticity, strong cushioning force, shock absorbing performance and so on. For example, G-type corrugated paperboard is 30-40% lighter than solid fiberboard paper, and its strength (compared with the same size cardboard) is increased by 30-40%, and its weight is only half that of the traditional solid cardboard folding box. The customer can directly pack the inner packaging product into the transport package, eliminating the middle package and part of the shockproof lining, because the miniature corrugated packaging structure is more rigid than the traditional folding cartons. Thus, the miniature corrugated cardboard box is safe and strong, and the weight is Light, cost savings. And micro-corrugated board printing effect is good, can be suitable for a variety of high-precision printing methods, especially for offset printing. In other words, in the past, the traditional corrugated corrugated board could only be printed on a gravure machine, and it could not be offset directly as a photo-like high-definition pattern (due to compression deformation will destroy the strength of the board, greatly affect the accuracy and stability of the printing Sex, easy to cause cardboard deviation, uneven thickness, synchronicity that affects the printing speed results in ambiguous patterns, resulting in great unnecessary waste, which is a consensus reached in the industry for many years of experiments), if you want to get a cardboard offset The effect can only be increased by adding one pre-printed face sheet to the surface of a sheet of dewy cardboard that lacks a sheet of paper (also known as four- or six-layer corrugated cardboard). To this end, the industry has also developed a corresponding additional stand-alone: ​​special related tile auxiliary equipment - veneer to achieve this function; and this new type of micro-corrugated board, printed directly on the offset press, due to its above characteristics, It will not reduce or destroy the strength of the cardboard due to the deformation of the dents. This is undoubtedly ideal for today's prevailing economy and increasing demand for print quality. At the same time, in the case of corrugated board itself, the same number of sheets and the same pressure, the higher the number of twists, the lower the roll height, the higher the compressive strength of the plane pressure and the parallel pressure of the cardboard. This kind of pressure is the main source of force for the transportation of small carton packs.

Miniature corrugated packaging "upsurge"

The trend of micro-corrugated cardboard has risen. The United States, Sweden, Germany, Spain and other countries have begun to expand the production scale of F楞 and C楞. China's corrugated paperboard industry should do its best; Shaanxi should change its relative backwardness in technology, equipment and management, and increase the development of micro-corrugated paper market.

In recent years, in order to meet the requirements of packaging industry reduction and environmental protection, the trend of micro-corrugated cardboard has risen. For example, the United States, Sweden, Germany, Spain and other countries have begun to expand the scale of production of F楞 and C楞, and began to more subtle Direction exploration. Some countries have begun to apply N楞 (楞高 0.
