The usage of corrugated paper

Type A corrugated and type B corrugated boxes are generally used for transporting outer packaging boxes, and beer boxes are generally made of B. E is used as a one-piece box with certain aesthetic requirements and appropriate weight contents. F-shaped corrugated and G-shaped corrugated wags are called mini corrugated paper, which is a very thin corrugated, used as food for hamburgers, cream fillings, etc. Disposable packaging containers, or used as micro-electric products such as digital cameras, portable stereos, and packaging for refrigerated goods.

Corrugated paperboard began in the late 18th century. At the beginning of the 19th century, due to its light weight and low price, it was widely used, easy to manufacture, and can be recycled or even reused, which led to a significant increase in its application.

By the beginning of the 20th century, it has been widely popularized, promoted and applied for packaging and packaging of various commodities. Since packaging containers made of color corrugated cardboard have unique properties and advantages for beautifying and protecting the interior goods, they have achieved great success in competition with various packaging materials.

How to print on corrugated paper

In the case of corrugated printing, there is no special printing method, and embossing, gravure and offset printing are the main printing methods.

Beer box In the embossing process, before the corrugated paper is processed in the corrugated shape, it is first sent to the flexo printing machine for printing, and then bonded to the corrugated core and another backing paper to form a corrugated packaging material.

Corrugated paper is made of a resin material, whether it is a rotary printing or a single printing. Flexographic printing using water-based inks is an extremely effective printing method, regardless of the smoothness of the liner used to produce printed corrugated paper, which can be printed accurately and at high speed. In addition, the flexo ink has good opacity and can be printed in brilliant colors on the kraft base paper used for the production of cross-cut paper.

In the plate making process of the resin relief used in the past, the cleaning process using an organic solvent is indispensable, and then some media considering environmental compatibility, such as a plate which can be used only by washing, is used from the plate making process; A plate that can be used for development; a plate that uses a liquid photographic material for UV curing (recycling of unsensitized liquid), etc., all of which incorporate environmentally compatible printing methods.
