Future packaging design and industrial development trends (Part 2)

III. substitution and updating of packaging materials

the quality of packaging depends largely on the performance of packaging materials. Without good packaging materials, there can be no good packaging products. New packaging materials and new packaging technologies are the primary pursuit of packaging enterprises or research institutes. Now many new products and processes must be matched with new packaging materials to achieve good packaging effects

based on environmental protection requirements, packaging materials that pollute the environment and are not conducive to environmental protection need to be updated. New packaging materials are being developed, and some have achieved initial results, mainly including the following categories:

1. plastic packaging represented by EPS fast food boxes will be replaced by new paper packaging

due to the hazards of plastic packaging wastes in many places, plastic packaging, such as EPS fast food boxes, which are used in large quantities and difficult to recycle and dispose, has been restricted. The state has issued documents to list them as the packaging products that are mainly replaced under mild heating conditions (70oC). The new packaging made of pulp and plant fiber came into being and was listed as one of the key promotion projects by the state. EPS packaging products replaced also include EPPL packaging liners

2. plastic bag packaging materials are developing towards soluble and pollution-free materials

many cities have banned the use of ultra-thin plastic bags (packaging), so plastic packaging materials that do not pollute the environment need to be researched and developed. Such as composite plastic film in composite materials, various surface coatings, etc. The research on some new materials that can replace the existing plastic packaging materials has made progress, such as water-soluble plastic films and other degradable plastic films have been applied, especially some foreign enterprises are targeting the huge market in China. For example, some Japanese enterprises began to seek partners in China to establish joint ventures to produce soluble plastic films

3. wood packaging is looking for alternative packaging materials

because the United States and other western countries that supplement the chain of key supporting projects restrict the export of China's products on the pretext of finding "longicorn" in the wood packaging of China's export products, all products packaged in wood must be subject to complex special treatment or replaced with other materials. Due to the cost price and other problems, even using heavy corrugated boxes is not competent. Therefore, at present, China has been tackling key problems, and honeycomb cardboard boxes are recommended to replace them. However, the problem that some PE manufacturers in Asia and even those preparing to resell ethylene raw materials can withstand gravity and handling strength must be solved

4. other new auxiliary packaging materials also need to be studied

such as adhesives, surface treatment agents, inks, etc. Many cartons in our country have large paper consumption, high cost and low strength, because the quality and performance of these auxiliary packaging materials can not meet the requirements. In terms of packaging and printing inks, environmentally friendly inks (or green inks for short) have become popular internationally, and China is also making great efforts to develop them. For example, Zhuzhou Institute of technology has developed several multi-functional water-based inks in cooperation with Xianke group, which have been mass produced, and users have responded well after use

IV. integration of packaging and processing

many new packaging technologies are based on new packaging thinking. The new thinking of packaging is to go beyond the existing packaging technology and products and apply other relevant technology combinations to packaging to form a new packaging technology. There are several categories of technologies in this regard:

1. packaging curing technology - the renewal of curing and drying energy, from heat to light

2. packaging cutting and forming technology - new cutting and forming instruments

3. combination technology of packaging and processing - combination of packaging and processing

4. packaging function borrowing technology - packaging function exceeds packaging and has value-added effect

5. packaging function protection technology - add functional ingredients such as fresh-keeping, sterilization, moisture-proof, anti-static and anti odor into the packaging materials

in addition to the above five aspects, there should be other technologies, such as the packaging technology of live fresh goods (packaging of living packaging). In addition, with the emergence of new packaging materials, some technologies in the packaging process have also undergone new changes. For example, the appearance of self drying stretch wrapping film makes the wrapping, shrinking, binding and other processes integrated, and the operation is simplified and fast

the most promising technology mentioned above is the combination technology of packaging and processing. It solves many treatment processes, directly borrows the packaging mechanism, realizes the integration of packaging and processing, and makes the packaging more potential and effective

v. the packaging industry must rely on the industry.

the development of packaging industrialization is realized through the combination of technology and products to increase the market share in the market. The future packaging industry should have both characteristics and scale. Tetra Pak, for example, dominates the world by its characteristics and technology. With the emphasis on environmental protection, packaging recycling will become a new type of packaging industry, which will have faster development

the packaging industry must be supported by the industry, backed by equipment and technology, and take the road of collectivization. Many packaging enterprises established or jointly established by cigarette factories, cosmetics factories, pharmaceutical factories, distilleries, etc. have good product quality and economic benefits because they are supported by industries and have a stable market

specialization and technological innovation are the magic weapons for the packaging industry to remain invincible in the competition. The technology led technology-based packaging industry that injects the coating system into the mold cavity through a reactive injection molding (RIM) mixing head, such as professional can making factories, bottle making factories, capping factories, new packaging material factories, is a typical representative of this kind of packaging industry
