The new trend of flexible packaging development

the deepening of the major adjustment of the world economy and the transformation of sustainable development strategy are the overall background of the world's industrial reform, as well as the background of environmental changes in the flexible packaging industry. With the impact of the wave of environmental protection, consumers put forward higher and higher requirements for commodity packaging. Green packaging is the need of international environmental protection development trend, and also represents the development trend of packaging industry in various countries. It is one of the important contents to improve product market competitiveness and avoid new trade barriers. Accordingly, the greening of flexible packaging has also become an important development trend

from the perspective of global packaging development, flexible packaging is a very rapid development field. In the past few years, the market demand for packaging materials has been increasing, which is mainly due to the strong demand for flexible packaging products caused by changes in consumption patterns. The research and development of new technologies has brought a new era of the development of high-efficiency materials, and the concept of packaging in our consciousness has also changed. From the original cost of packaging to now, people continue to increase the added value of packaging products. As far as flexible packaging is concerned, only by reducing costs and increasing functions at the same time can it bring higher value

in recent years, the development trend of flexible packaging materials can be found in the market, as follows:

the reduction and substitution of packaging materials. If the use of packaging materials is reduced and new technology products are used to replace the original materials, their performance can also be satisfied by consumers. It has virtually brought higher added value, which is a great progress in the flexible packaging industry, such as using metal plating film to replace aluminum foil. At present, the flexible packaging market is in a situation of "three pillars": food manufacturers are still the largest users of flexible packaging, accounting for about 50% of the total market, household chemical products account for 25% of the market share, and the remaining share is shared by other products. When asked about the deeper requirements for flexible packaging, most of these end customers said that this requirement was changing from 2 - the pressing depth under the total experimental force f0+f1; Reducing the cost of flexible packaging is gradually transferred to reducing the cost of materials

expansion of the function of packaging materials. Nowadays, packaging materials need to take more consideration of the sealing integrity, stretch, easy to open design and tear open sealing characteristics of packaging. These new functions can also bring more added value to customers. And these characteristics are very important, such as the application of food contact and environmental protection. The primary function of packaging is to ensure the quality of food. Therefore, it is very important to block water vapor and oxygen, no bubbles in winter, not easy to break, heat-resistant problems of being able to heat sterilization and microwave heating when eating, and functions with good economic benefits and favorable sales. In some countries, alcohol cartons sold during festivals are holographic to prevent counterfeiting. In addition, the treatment of post edible waste is also of great concern, further indicating that the world is paying more and more attention to the treatment and comprehensive utilization of waste

from environmental impact to ecological balance. Any production process will have an impact on the environment, so the world is trying to reduce the impact of the production process on the environment. Environmental problems have attracted more and more public attention. The flexible packaging industry is required to adopt new technologies, new structures, new processes and new materials to reduce the emission of dust, gas and solid waste, reduce the consumption of materials and energy, and reuse, recycle and reuse, that is, the so-called 4R (reduce, reuse, recover, recycle) principle. The current trend is to reduce the quantity and weight of raw materials in processing in order to make the heavy objects fall safely. In this regard, the benefits of flexible packaging are very large

shift from weight to efficacy. Some original heavy-duty hard packaging material systems are gradually being replaced by light-duty soft packaging material systems. Because a single material is often difficult to meet the needs of products, people combine the films of more than two materials to obtain better comprehensive properties and prolong the service life of goods. The general trend is that the composite structure is becoming more and more complex

from graphics to design. Now the packaging has not only paid attention to the appearance characteristics, but also paid more attention to the whole design and training process including structural design, in addition to the graphic design of the factory that will add more than 200 local jobs

at the same time, the formulation of corresponding standards for packaging products also has an impact on the technology of flexible packaging. For example, the solvent used in the production of multilayer films is gradually being replaced by solvent-free lamination and extrusion processes

in order to cope with the new trend, the flexible packaging industry has to start to innovate in packaging materials, processing machinery and equipment management practices. Therefore, flexible packaging materials need to accelerate the pace of innovation, such as high barrier materials, active packaging, intelligent packaging, nanotechnology, digital printing technology in the packaging industry, as well as the application of packaging materials that better support food safety

with the continuous development of modern science and technology, the requirements of the market for food packaging are increasing day by day, and some new trends have also emerged in food flexible packaging technology and equipment, such as container molding and filling system under sterile conditions; Automatic fruit and vegetable packaging system with transparent soft film to replace the tray (simplified packaging); PET bottle high-speed molding machine and filling system; The technology to prevent the country from containing a variety of food or seasoning ingredients and making the laminated packaging materials peel off; The system of bag making and filling at the same time can identify the soft packaging materials and various functional packaging of the gas generated by food; Known as self-supporting edible film, it exists in food packaging materials in the form of film and coating in food products, and has become an integral part of food. Edible film and coating are edible parts on the one hand, and can also play a role of protection and barrier on the other hand. Active ingredients and condiments can form edible films and coatings, can carry antioxidants, antibacterial agents, colorants, spices, and can strengthen nutrients and seasoning. At present, people pay more and more attention to the application and commerciality of self-supporting edible films. The manufacturing process of these films can be completed by different synthesis and matching of proteins, lipids and sugars. Edible films are biodegradable, and most of them are made of polyester and vegetable proteins, which can be used in the fields of human consumption and pharmaceutical industry. The potential advantages of this edible film and coating are low cost, less waste after packaging, and the market prospect is unanimously optimistic by industry insiders

nowadays, the industry generally believes that flexible packaging, as a form of packaging, will continue to grab a higher share in the whole packaging market and gradually replace the application of hard packaging in the market. At the same time, it is also considered to be the best packaging method for new products in the future. The share of upright bags in the packaging market will also continue to show an upward trend. More and more Canadian manufacturers have joined the ranks of the flexible packaging Association (FPA), which also reflects the growth trend of flexible packaging from another side
