core tip: data shows that the amount of plastic used for food packaging accounts for 1/4 of the total plastic output. It can be said that as soon as plastic used for food packaging appears, garbage will be generated. In supermarkets and shopping malls, many food packages are made of plastic. The plastic inflatable packaging of puffed food can prevent moisture, oxidation, fragrance, sunlight and extrusion, but such a large packaging is a great waste of resources; There is also the packaging of instant noodles. Plastic packaging is far more than the packaging of paper bowls (or barrels). The sales price of bowls or barrels of instant noodles in the market is generally higher than 1/3 of the sales price of packaged instant noodles of the same quality. However, because this packaging method is convenient to eat, especially when traveling, it can be eaten directly by boiling bubbles after opening the cover, and there is no need to bring other containers, so it is very popular with consumers

[China Packaging News] according to data, the amount of plastic used for food packaging accounts for 1/4 of the total plastic output. It can be said that as soon as plastic used for food packaging appears, garbage will be generated. In supermarkets and shopping malls, many food packages are made of plastic. The plastic inflatable packaging of puffed food can prevent moisture, oxidation, fragrance, sunlight and extrusion, but such a large packaging is a great waste of resources; There is also the packaging of instant noodles. Plastic packaging is far more than the packaging of paper bowls (or barrels). The sales price of bowls or barrels of instant noodles in the market is generally higher than 1/3 of the sales price of packaged instant noodles of the same quality. However, because this packaging method is convenient to eat, especially when traveling, it can be eaten directly by boiling bubbles after opening the cover, and there is no need to bring other containers, so it is very popular with consumers

with the improvement of environmental protection requirements, it is necessary for consumers to eliminate backward packaging. The improvement of plastic materials is also a top priority. The food in the market segment can be packaged in paper, so as to reduce the waste of plastic and environmental pollution, which is also beneficial to future generations

the return path of paper packaging

the rapid development of China's food industry has provided a broad space for the development of paper packaging. It is expected that in the future, circular economy will become the main mode of the development of the packaging industry, the recycling of packaging waste resources will be industrialized, green packaging materials will be vigorously developed and developed, and the development of basic packaging industry will also be accelerated

the future packaging world is made of paper. The world calls for green packaging and cherish our home. Paper technology will be widely used in the packaging industry, and green packaging will become the main development trend of the bakery packaging industry in the future. However, replacing wood with paper, plastic with paper, glass with paper, and metal with paper has become the consensus of sustainable development. Paper materials have more renewable natural raw materials and more environmentally friendly recycling, which fully demonstrates the development potential of paper materials

under the homogenization trend of various commodities nowadays, packaging has become the third important factor to determine sales and establish brand image after commodity quality and after-sales service. From the original function of commodity protection and convenient use, packaging has developed to increase commodity value, shape brand and promote sales. Packaging design has become an important part of commodity marketing plan. As the first of the four major packaging, paper packaging, with the continuous development of paper materials and processing technology, has increasingly diversified shapes and more creative liquidity

five technologies worthy of attention in the field of paper packaging printing

1. Offset online cold pressing technology

traditional hot stamping requires a special metal cup to take the hot stamping plate, and the required hot stamping materials are transferred to the surface of the substrate material by heating and pressing. The speed of paper conveying is relatively slow, so it is difficult to be online hot stamping with offset printing. Offset online cold pressing technology is to paste the pictures and texts that need to be hot stamped in view of the huge utilization prospect of new materials to the surface of the substrate through adhesives at room temperature. The realization method is to directly use the two units of the original offset press, one group of printing adhesive layer and the other group of transferring metal hot stamping foil

advantages: fast hot stamping speed and high efficiency; Printing and metal foil transfer digital printing are completed by one-time paper feeding, with high registration accuracy; The resolution of cold hot plate can reach the resolution of offset printing plate, and fine pictures and texts can be hot stamped; It is carried out at room temperature without heating, and can be hot stamped on the surface of temperature sensitive materials; Save energy

2. Web bronzing technology

web bronzing machine has taken the lead in mature application in China's cigarette bag market, and will achieve greater development with the increase of market demand for high-efficiency and high-quality hot stamping live parts. At present, enterprises with relatively mature applications include Changde Jinpeng Printing Co., Ltd., Yunnan Qiaotong Packaging Printing Co., Ltd., Yunnan Yuxi Printing Co., Ltd., Chongqing Hongsheng Printing Co., Ltd., Yunnan Jiujiu Color Printing Co., Ltd. and Dongguan Zhiyuan Color Printing Co., Ltd. Enterprises that often encounter live parts with large quantities, high requirements for bronzing process and short customer delivery time can pay special attention to web bronzing technology

Laser holographic laser transfer paper is a new type of packaging material that is more and more widely used in the packaging and printing industry at home and abroad, but a major problem is that it is easy to produce laser plate sewing rip when printing on the rotary gravure press, resulting in great waste. At present, there are mainly two fixed length stretching solutions: online and offline, and the room should have enough space for printing to avoid laser plate sewing technology solutions

packaging and printing enterprises can make reasonable choices according to their own funds and actual production conditions. If the enterprise has rotary gravure printing equipment, it can adopt the offline solution to press concave convex, and purchase laser aluminized transfer paper that can avoid plate sewing from the composite paper manufacturer. It only needs to transform the paper feeding mechanism of the original rotary printing equipment, so that the investment risk and technical risk of the enterprise are small

4. Laser pattern imprint transfer technology

laser pattern imprint transfer technology is a high-tech integrating decoration, anti-counterfeiting and environmental protection. Its outstanding advantages are: it meets the requirements of environmental protection, has good anti-counterfeiting effect, and reduces production costs

5. Combined printing technology

in a sense, combined printing machine is no longer simply a printing equipment, but a flow-through production line integrating a variety of printing and post press processing processes

combination printing is a combination of various printing processes and technologies, that is, integrating various printing methods (such as flexo printing, offset printing, gravure printing, ink-jet printing, and even digital printing) and post press processing processes (such as glazing, lamination, die cutting, indentation, hot stamping, embossing, etc.) on the same production line, combining the advantages of various printing and post press processing methods to complement each other, So as to obtain the best printing effect through the most in-depth investigation and Research on the production line 1 of the enterprise
