[China Packaging Network News] The industry pointed out that paper packaging is currently the people's green packaging, which has many advantages in energy conservation and resource conservation. As far as the international market is concerned, the era of food paper packaging has come.
Analysis of Development Trend of Foreign Paper Packaging Industry
At present, the development of foreign paper packaging and printing technology has the following new features: single-layer material development to multi-layer materials; offset, gravure, flexo, screen printing and other printing methods coexist and flexographic printing will grow fastest; The development of sheet-fed web and single-machine-to-line production; comprehensive application of various new technologies (such as computer design, digital technology, laser processing technology and new materials, etc.) continues to optimize the entire production system.
The development trend of foreign paper packaging containers is: once formed molded paper containers will gradually replace the current die-cutting combination paper containers; deep plastic coating technology will gradually replace the past wax coating; composite technology has become an important technology for the development of paper containers; CAD and CAM The system will greatly shorten the design and manufacturing cycle of paper packaging containers. In addition, paper product packaging focuses on the development of low-weight, high-strength, lightweight, high-grade paper packaging that meets the goals of standardization, serialization, multi-species, multi-substrate, and multi-purpose.
Japan launches new glass wrapper
The rapid development of the packaging industry in recent years has ushered in a vast market as an indispensable package material. At the same time, the constant diversification of people's needs also puts higher demands on the packaging market. Recently, a Japanese company launched a new type of glass wrapping paper that can extend the shelf life of fresh food.
A Japanese company launched a new type of glass wrapper for packaging raw foods such as fruits and vegetables, which can be matured to extend the shelf life by a factor of 2. The surface of the cellophane is coated with a special chemical called decyl alcohol, which can promote the activity of mature ethylene producing enzymes in fruits and vegetables, thereby prolonging its preservation period. The use of such wrappers not only facilitates long-distance transportation of such foods, causes the loss of college students, but also reduces the use of preservatives and reduces costs.
Analysis of Development Trend of Foreign Glass Packaging Industry
Glass packaging industry In order to compete with new packaging materials and containers such as paper products containers and plastic bottles, glass bottle manufacturers in developed countries have been devoting themselves to making product quality more reliable, aesthetically pleasing, cheaper and cheaper.
In order to achieve these goals, the development trend of foreign glass packaging industry is mainly manifested in the following aspects:
Using advanced energy-saving technologies
Another way to save energy, improve melting quality, and extend the furnace to save energy is to increase the amount of broken glass. The amount of broken glass imported abroad reaches 60%-70%. The ideal is to use 100% broken glass to achieve the goal of "ecological" glass production.
Bottles lightweight
In developed countries such as Europe, America and Japan, lightweight bottles are the leading products for glass bottles and cans.
Obedand company's glass bottles and bottles, 80% are lightweight disposable bottles. Precise control of raw material composition, precision control of the entire process of melting, NNPB, cold and hot end spraying of bottles and cans, on-line detection and other advanced technologies are the basis for realizing lightweighting of bottles and cans. Some countries are developing new surface enhancement technology for bottle cans in an attempt to further reduce bottle weight.
Improve labor productivity
The key to improving the productivity of glass manufacturing is how to increase the molding speed of glass bottles. At present, the commonly adopted method in developed countries is the use of multi-group, multi-drop molding machines. Large-scale kilns that match high-speed molding machines must have a large capacity to stably supply high-quality glass liquids. The temperature and viscosity of the gobs must meet the requirements of the best molding conditions.
For this reason, the raw material composition must be very stable, and the refined standard raw materials used by glass bottle manufacturing companies in developed countries are mostly provided by specialized raw material production enterprises. Melting quality of the furnace thermal parameters to use digital control systems to achieve the best control of the entire process.
Increase production concentration
In order to adapt to the severe competition situation caused by the challenge of other new packaging products in the glass packaging industry, a large number of glass packaging manufacturers have begun mergers and reorganizations to increase the concentration of the glass container industry in order to optimize resource allocation, increase economies of scale, and reduce unordered competition. Enhancing development capabilities has become the current trend of the world glass packaging industry.
It is expected that the circular economy will become the main mode for the development of the packaging industry in the future, recycling of packaging waste resources will be realized in industrialization, green packaging materials will be greatly developed and developed, and the basic packaging industry will also accelerate development.
