Technical Field

Background

The packaging industry is an important supporting force for national economy and social development as a service manufacturing industry. Nowadays, China has become the second major country of world packaging product production and consumption, the whole annual income of the packaging industry is about 20000 million Yuan, the annual income of a 'paper and paperboard container' plate which is one of the major business of the industry is about 4000 million Yuan, the proportion reaches 20 percent of the total value, and is far higher than that of other subdivision businesses. Over the years of development, the good packaging effect of paperboard containers has gained widespread acceptance and acceptance by the market and users, and the scope of the related business fields is becoming increasingly broad, detailed and deep. The more and more orders for cardboard container manufacturers are accompanied by increasingly higher quality and accuracy requirements in terms of quality, dimensions, specifications, etc. of the container making bindings.

This is both an opportunity and a challenge. The reason is that most cardboard container manufacturers produce and use the cardboard containers by purchasing and introducing existing processing equipment on the market, and do not have the capability of designing, developing and technically modifying equipment, and the original precision of the already-produced processing equipment determines and limits the precision of the processed products. This means that alternative and effective ways to further improve the quality of the produced cardboard containers are often to purchase new equipment from equipment manufacturers or to make large scale changes to older machinery. However, the price of a single automatic cardboard container binding line on the market is about 100 thousands, the selling price of the international famous brand is more 200 thousands, and the selection of the way will undoubtedly increase the operation cost and burden of enterprises, which most of small and medium cardboard container manufacturers can not bear.
