The new trend of the future corrugated paperboard market - introduction of ultra-thin G-boards

First, the definition of ultra-thin corrugated board is generally referred to as E楞, F楞 and G楞 as the general name for ultra-thin concrete.
In today's development, we use E楞 to improve the quality of printing, but we also need to use beauty makeup or preprinted base paper to produce.
The ultra-thin corrugated board has been regarded as the mainstream of the future corrugated board packaging market, because it has the dual effects of better physical properties and printing quality of corrugated board and cardboard.
Ultra-thin corrugated board has become a revolutionary product in the corrugated board industry and board industry. It will be widely used in two industries.
The following table shows the most important indices for ultra-thin ticks:

Second, the current market situation in Europe and the United States According to a major paper trader data, ultra-thin corrugated board market will grow at an alarming rate of 20% each year.
At present, ultra-thin corrugated plates in Europe and the United States include E楞, F楞, and G楞, and the total production value accounts for approximately 8% of corrugated plates. Within five years, it will continue to grow. In particular, G楞 will replace 10% of the cardboard market within five years. In other words, G楞 will be the trend to guide the future market.
Years ago, recycling laws and actions have been implemented in Germany, the United Kingdom and France. As a result, the demand for ultra-thin plutonium has been greatly increased, especially G楞. Because it can be directly printed on the screen printing machine, the user's demand for the manufacturer is even more urgent.
We are convinced that in the future ultra-thin corrugated board will replace cardboard, such as parcel boxes, detergent boxes, face paper boxes, sanitary product boxes, frozen food boxes and heavy industrial boxes for toys. In particular, cartons exceeding 400 g/m2 will be replaced by ultra-thin cartridges.
In Europe and America, the growth of the corrugated board industry has been proven for many years. In 1998, 30 sets of G roll corrugated rollers were installed in the European market and 25 sets were installed in the US market. Another 50 sets were also installed one after another in 1999.
III. Potential in Japan From April 2000 on, the law on recycled paper will affect the demand for cartons. Therefore, the replacement of cardboard by the demand of the G board will increase.
However, there are still three issues that need further discussion:
1. Is the accuracy of G board printing the same as cardboard?
2. How is the manufacturing cost?
3. How about the supply of raw paper for the G board?
These actual problems not only occur in the corrugated paperboard industry, but also the paper industry and the carton industry.
In Europe and the United States, many companies are also producing G-Boards to meet customer needs. In fact, more companies also hope to invest in the production of G-Boards in the future.
At present, it is a trend to replace the use of color-printed E papers with G cards, and a large number of consumers use cardboard boxes such as detergent manufacturers, plastic wraps, hygiene products, frozen foods, and instant foods. In particular, large companies have begun to use G-boards for packing.
Fourth, the advantages and disadvantages of G board and cardboard

V. Factors for the production of corrugated board machines for G-boards According to the BHS company R&D staff, the use of conventional wire harnesses for the production of ultra-thin boards must be adjusted taking into account the following factors.
1, 楞 type species.
2. Steam heat control: (1) single tile machine; (2) belt type pressure roller; (3) double tile machine.
3, Roller: Roller wall heating system should be considered to use the roll (having high-efficiency heat transfer effect).
This type of roll ensures that the roll can be warmed by the cold speed and evenly heated to the average paper web including both ends.
4, the original paper force control (1) stable and high speed of the paper-contacting machine;
(2) Dual original paper force control system.
5, paste car and paste (1) paste to be suitable for high-speed car ultra-thin corrugated board light base heavy plate width of the use of paper;
(2) The gap between the roller and the upper roller must be controlled to 0.01mm.
6. Tension control of the overpass (1) It is better to use the flyover guide of German E&L company and the tension control system of BHS.
(2) Low basis weight raw paper is suitable for producing ultra-thin plates.
7, paste car: pressure shoe paste gap adjustment system should be considered 8, double tile machine: thermal control - BHS Bartrol double tile machine (1) hot plate area: most of the cardboard bending is due to the high temperature, and the gravity roller needs to Paper width material and roll speed automatic adjustment;
(2) cold plate area: pressure plate type.
9, cross-cutting knife (1) has a short cut capacity: 245m/min (500mm long);
(2) The accuracy of vertical cutting must be suitable for screen printers.
Six, ultra-thin corrugated board task In order to achieve the goal of producing ultra-thin corrugated board, the following factors are important production indicators and tasks that need to be challenged in the future:
1. How to improve the efficiency of tile lines 2. It is necessary to develop a base paper suitable for ultra-thin corrugated plates. This is the task of the base paper mill.
(1) Lightweight heavy paper: front paper = 135g-80g/m2;
(2) Average water control and raw paper thickness control.
3, paper dust measurement (1) tile factory: paper dust dust environmental protection system;
(2) Base paper manufacturer: dust-free base paper.
4, how to prevent cardboard bending (1) tension;
(2) heating control;
(3) Paste control.
5, how to improve the productivity of small order production box and use the back mill to put into production. (Chen Congyong, General Manager, BHS Taiwan Branch, Germany)
