Corrugated paper: Packaging industry's most widely used packaging materials

Corrugated paper is the most widely used packaging material in the packaging industry. It can be applied in many fields such as packaging industry products and various kinds of civilian goods. With the international market restrictions on the quarantine of goods and wood packaging, wooden boxes and metal boxes have been replaced in many cases. The following will analyze some of the characteristics of packaging corrugated paper:

1, good compression performance. Regarding the characteristics of the corrugated paper itself, the micro-corrugated board has more compressive performance than a normal solid paper 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 for packaging compressive strength to speak, using microwatts packaging is an ideal choice.

Ice cream is a food that needs to be frozen. It is easily affected by the external environment and causes shape deformation during transportation. Due to the small size of the fine corrugated packaging. The large number of corrugated strips per unit area increases the compressive capacity of the package and provides better protection for the product, making it ideal for ice cream packaging. Moreover, in addition to the advantages of high compressive strength, good cushioning properties, and the like, the micro-corrugated packaging also has superior properties such as low temperature resistance and moisture resistance.

2, strong buffer. 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. It is an ideal cushioning material.

Now, many perfumes, cosmetics, etc. are lined with micro-corrugated cardboard, which not only improves the compressive strength of the package, but also enhances the packaging quality. Many digital and small home appliances are lined with micro-corrugated cardboard to replace traditional buffer materials such as EPE and EPS. Due to the selection of a piece of fine corrugated paper and the selection of high-strength corrugated base paper, the cost is more economical and more environmentally friendly. In a sense, corrugated paper products are easily recycled and recycled and are ideal "green packaging" materials.

3, the printing effect is good. In the past, the traditional corrugated corrugated board could only be printed on the concave board. It could not directly offset the exquisite photo-like high-definition pattern. The deformation due to compression would destroy the strength of the board, greatly affecting the accuracy and stability of the printing. The synchronism caused by paperboard deviation, uneven thickness, and influencing the printing speed may cause blurring of the pattern, resulting in great unnecessary waste. Miniature corrugated cardboard can be directly printed on offset printing, which can not only obtain beautiful patterns, but also can not reduce or destroy the strength of cardboard by deforming the corrugated fiber due to printing. The direct printing of offset printing makes the fine corrugated packaging printing more exquisite and highly displayable. In foreign countries, micro-corrugated packaging has begun to use more direct offset printing methods, the printing effect is more beautiful, greatly improving the packaging grade. Therefore, more and more industries begin to use fine corrugated packaging as sales packaging. Except for traditional food, toys, household appliances and other industries that are used in large quantities, industries like crafts, gifts, etc. that require external packaging gifts begin to use micro-tiles. package.

The exquisite printing effect is the reason why many cold drink users insist on using fine corrugated packaging. Products such as Nestle's Moonlight Box and Lu Xue's Melaleuca Snow Ice Cream are all in micro-corrugated packaging. On the one hand, as a sales package, it requires beautiful and beautiful printing. On the other hand, as an inner package, it is required to be able to withstand low temperatures. Most of the fine corrugated packaging are printed by direct offset printing. The printing effect is good, the printing color is brilliant, and the color expression ability is very strong. After coating with UV varnish, it not only achieves the effect of preventing the level, but also makes the compressive strength of the package improve.

At the same time, the fine corrugated cardboard has better physical properties and better printing adaptability. The packaging box of the ice cream layer is printed in color. The pattern is exquisite and the color is gorgeous. It embodies a strong realistic visual effect. In the heart of consumers' desires, it gives us a beautiful enjoyment.

4, save costs. With the gradual and standardized development of the logistics industry, for the advantages of high hardness, high strength, light weight, low cost, and ease of printing of micro-corrugated board, E楞 miniature corrugated cardboard has been used instead of the single corrugated papers used in the past, such as B楞, C楞, etc. package.

The improved packaging can not only meet the requirements for safe transportation of the original product, but also can reasonably reduce the packaging materials and transportation costs each year.

Fine corrugated cardboard is used to make poster-type corrugated paper display racks, which facilitates transportation and saves costs. As the fine corrugated type is smaller, the printability is better and the printing is more exquisite. This is a better choice for display packaging such as poster type corrugated cardboard display racks. 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 frames, not only corrugated cardboard is used at the bracket, but a large number of micro-corrugated cardboards such as G楞, N楞, and F楞 are used in place of traditional ones. The PVC sheet makes the entire poster-type corrugated cardboard display rack lighter, not only convenient for transportation, but also easy to recycle, and the price is lower.
