Innovate the concept of recyclable paperboard

ten years ago, recyclable paperboard could not compete with the original paperboard because of its poor printability, insufficient strength, and non-uniformity. With the improvement of coating technology, cleaning technology, printing technology and papermaking technology, the previous shortcomings have become insignificant. But even so, people still have deep-rooted misunderstandings and prejudices about recyclable cardboard more or less

some traditional concepts that need to be eliminated:

rob is the Deputy Marketing Director of a manufacturer that produces and processes recyclable paperboard in the United States. When he first entered the industry in 1974, recyclable paperboard had many shortcomings compared with solid non bleached/solid bleached kraft paper (Sus/SBS). Although this printing material now has a good cost performance in the market, it used to have the following shortcomings: poor printing surface performance, unclean surface, high mechanical pressure directivity of strength, and is considered not suitable for food packaging The minimum thickness used should be greater than 0.02 "Poor side uniformity. After all, these things were before 2003, and now all these have changed.

concept 1: recyclable cardboard should not be used for food packaging.

when consumers still doubt that recyclable cardboard is used for food packaging, many people do not realize that it has been used for food packaging for many years. Since a product called Quaker Oats entered the market 50 years ago, recyclable cardboard has been widely used It is applicable to cereal packaging cartons and snack food packaging, etc. Due to the improvement of coating technology, the paperboard also occupies a place in the field of frozen food. However, in the packaging industry, there are still some people who still oppose its application in food packaging. An insider said, "people are worried that they don't want to put food directly on recyclable cardboard. But what they don't know is that 100% of recyclable cardboard complies with the regulations and standards of FDA on direct contact with food." Another person said that "recyclable cardboard used for food packaging is somewhat different from that used for outer packaging. Changes have taken place in the past few years, and more and more people begin to use it as food packaging. "

concept 2: the surface printing performance of recyclable paperboard is poor, which is not suitable for high-end activities. Years of research and development have made the appearance of recyclable paperboard brighter, whiter and stronger. More and more companies have also begun to examine this kind of printing material with a new perspective. The R & D and supporting capabilities of new coatings such as oil-resistant and aluminum resistant processing enterprises are constantly improving, and grease coatings are suitable for cold storage linings; Together with the improvement of chemical cleaners and printing technology, it is possible for recyclable paperboard to replace original fiber paper. Users are also increasingly finding that it has the advantages of low cost and attractive packaging. Industry experts said: "in the past, many companies believed that SBS uniquely represented hygiene and aesthetics. This is because in the past, SBS had good printing surface performance. Now, people began to realize that recyclable paperboard not only has good cost performance, but also saw the advantages of good printing adaptability and more stable packaging."

concept 3: the strength of packaging with recyclable paperboard is not enough

the efforts of the product technology research and development department and the ever-changing industrial technology have quickly solved the other two problems of recyclable paperboard, that is, the problem of strength and thickness. Relevant experts in the United States pointed out that recyclable paperboard and original paperboard can obtain the same strength under the same thickness. Packers do not need to increase the thickness of recyclable paperboard to improve the strength of the paperboard. In 1992, the paperboard with a thickness of 0.010 "~0.018" produced by the manufacturer was inferior to SBS or sus in performance. Today, due to technological improvements, the paper is competitive in structural strength, and its printing performance has reached or exceeded that of the original paperboard

concept 4: the uniformity of recyclable paperboard is poor

the improvement of production machinery has prompted the paper producers to use photoelectric switches to detect the number of twists and turns. The automation of experiment sequence has improved the accuracy of paper monitoring, and finally a stable printing surface has been obtained. Due to the improvement of various technologies in the paperboard production process, if it is not used for a long time and the improvement of the ability of computer monitoring paperboard, now the factory can successfully produce paper with good uniformity, and the uniformity of the paperboard is no longer a problem

the improvement of cleaning equipment, coupled with the improvement of bonding coating technology, has also greatly helped recyclable cardboard manufacturers. "More advanced cleaning equipment has improved the quality of recyclable paperboard so that it can keep up with the new printing machine technology - speed and quality requirements," said the vice president of a paperboard manufacturer in the United States. The improvement of clean technology has greatly reduced the pollutants in the production process (this pollutant is easy to reduce the efficiency of the printing machine), which makes the products have the performance of keeping away from metal particles. In addition, the modified adhesive coating also meets the requirements of higher printing speed and print performance

environmental considerations

as mentioned above, recyclable paperboard has its own advantages in cost performance and quality. Another outstanding advantage of its performance is environmental protection. According to the environmental protection manager of FedEx company in the United States, the company's annual savings in environmental protection expenses due to the use of recyclable cardboard are as follows:

1. 30% of the energy is saved, which is equivalent to lighting 30000 60 watt bulbs

2. 140 million gallons of water were saved, which is equivalent to the water consumption of 1500 households for a year

3. More than 3900 tons of solid waste are saved, which is equivalent to the amount of waste produced by 5000 people a year

4. About 4000 tons of wood are saved, which is equivalent to 1.6 million reams of copy paper

however, although the production of recyclable paperboard can obtain substantial environmental benefits, it is not easy for most companies. Consideration must be given to the harsh marine environment that the paper packaging may have to withstand; Objective factors such as expensive and heavy computer equipment are needed
