Corrugated carton process technology development new trends

As a traditional green packaging material, corrugated paper has been widely used in the packaging and transport packaging of various products because of its advantages of light weight, high strength, easy processing and forming, easy storage and handling. In recent years, although the market for corrugated boxes has been affected by the emergence of recyclable plastic containers, a recent survey by the European Federation of Corrugated Board Manufacturers and the French Corrugated Cardboard Packaging Association shows that although recyclable plastic boxes are in Europe, The market share in fresh product packaging reached 31%, but corrugated cardboard packaging still holds the first place with 48.2% market share in Europe and will continue to maintain this leading position in the next few years. According to relevant experts, with the development of modern science and technology, many countries have made some new achievements in the research of corrugated box technology.

Development of fine corrugated cardboard

The “C” crucible is 40% lighter than solid fiberboard, but the board strength is increased by 40%, which means that less packaging material can be used to achieve the same retention performance. Customers can directly pack the inner packaging product. Into the transport packaging, eliminating the intermediate packaging, saving packaging costs. At present, companies in the United States, Sweden, Germany, Spain, etc. have begun to expand the production scale of F and G. They have even started to apply more fine-grained corrugated papers such as N楞 (0.46mm in height) and 0楞 (0.30mm). material.

Wax cartons recycling new process

Recently, there has been a patented processing technology named XTrax. It has been proven that this technique can successfully separate the pulp fibers of the waxed carton from the wax and reduce the wax content of the paperboard to a reasonable level.

In particular, this technology does not require complicated equipment, harsh operating conditions, or changes in beeswax itself. The emergence of this new technology completely solves the problem of recirculation and recycling of waxed corrugated cartons, and it also makes many wax-coated corrugated cartons free from the threat of closure.

Corrugated box molding system

The new technology CE+P system uses the cam as the main driving force to transfer energy to the sliding crank assembly. The carton blank is transferred from a large-capacity supply hopper to a carton forming position by a plurality of adjustable collection rollers through a continuously operating vacuum supply device. Each roller is equipped with a sensor device. Once the carton blank arrives at the designated position, it is step-folded and the handles on both sides of the conveyor belt ensure that each molded carton is square. The box making speed of CE+P system reaches 25 per minute.

Carton Container Management System

Since the agricultural products come from different growers and markets, the fruits and vegetables generally shipped to retailers are mixed and loaded with cartons of different sizes and styles, which can easily cause product damage. To solve this problem, Easy Stak uses international standards to regulate two key indicators of corrugated boxes: stacking ability and mixed assembly load performance. It is not only suitable for fruit and vegetable packaging, but also can be widely used for packaging of fresh products such as yogurt, in addition, can also be used for dessert and frozen food packaging.

Corrugated board pallet size standardization

In view of the different sizes of corrugated cardboard packaging produced by different manufacturers, in order to better display the advantages of corrugated cardboard packaging and to adapt to the actual conditions of the European countries' fruits and vegetables circulation market, it is convenient for the transfer of fresh products between European countries and the group goods. European corrugated cardboard The Federation of Manufacturers, with the assistance of relevant companies, has introduced the size standards for corrugated packaging trays of fresh products such as vegetables and fruits. The main purpose of the standardization of the size of the corrugated cardboard tray is to unify the external dimensions of the tray and optimize the stacking of the paper tray on the wooden tray.
