Product packaging is the most direct and vivid reflection of corporate image. Packaging image includes corporate logos, trademarks, standard fonts, standard colors and other corporate image elements.
Modern enterprises pay more and more attention to the packaging image of products, because the establishment and recognition of famous brands first go through the establishment and recognition of product packaging image.
After packaging products are displayed and consumed in large quantities and repeatedly, their commodity image directly and effectively imprinted in the minds of consumers.
Any scientific and reasonable packaging can summarize, vividly, concentrate, and profoundly reflect the quality connotation of the product and show the quality image of the enterprise. This point of view is widely recognized by the business community.
Therefore, packaging has become the most basic and important means for enterprises to establish their image and create famous brands.
Packaging Resources and the Environment
The consumption of resources and the protection of the environment are two hot issues in the global ecology.
Packaging is closely related to it and has become one of the focuses of these two issues.
The materials used in packaging manufacturing consume a large number of natural resources; in the process of packaging production, the toxic and three wastes that cannot be decomposed cause pollution to the environment.
A huge amount of packaging waste has become an important source of environmental pollution; these factors are contributing to the vicious ecological cycle of nature.
Countries around the world have invested heavily in this, and the problem has been brought under control, but it is still serious.
Packaging and Resources
The earth’s natural resources are not inexhaustible, and the formation of each substance takes a long time.
The massive logging of forests has seriously damaged the earth’s climate and ecological balance, and the world’s forest area is less than 32% of the total land area.
More than 70% of packaging industrial products are disposable and become waste after use.
The product life cycle is shorter than other industrial products, so it consumes a lot of resources.
For example, the paper and cardboard used for packaging in the United States account for 90% of the total paper products, which fully shows that packaging consumes a considerable number of natural resources.
From the perspective of material saving and energy saving, the packaging should be streamlined and reasonable to prevent excessive packaging and exaggerated packaging.
Fully consider the lightweight of packaging materials, and adopt measures such as improving the comprehensive packaging performance of materials to explore thin-walled containers and seek new substitute materials.
Under the premise of packaging requirements, paper and plastic materials are used instead of metal and glass packaging materials.
At present, milk and fruit juice beverage products are basically packaged with paper-plastic composite packaging materials, and are packaged with aseptic packaging technology.
On the one hand, they save a lot of packaging energy and costs, and at the same time, they also better maintain the original flavor and quality of food.
In addition, by improving the packaging structure, realizing packaging mechanization and automation, and strengthening packaging standardization and quality management, the purpose of saving materials and energy can also be achieved.
Packaging and Environment Protection
When human beings carry out product packaging, they can only pay attention to the protection of the ecological environment from simply solving the most basic functional needs of human beings to all aspects of human living environment conditions.
The packaging industry should strive for low consumption and high efficiency, so that products can be reasonably packaged, and at the same time, solve the problem of recycling and proper disposal of waste packaging.
As far as food packaging is concerned, it is necessary to first solve the problem of reasonable positioning of products and packaging, resist excessive packaging, give priority to the use of high-tech packaging technology and high-performance packaging materials.
And minimize packaging materials and increase duplication under the premise of ensuring the value of the product.
Utilization rate, reduce the cost of comprehensive packaging; secondly, we should vigorously develop green packaging and ecological packaging, and study the recycling and disposal of packaging waste.
Green Packaging
So far, although there is no clear definition of green packaging, the generally accepted “green packaging” refers to recycling or degradation, saving resources and energy, and packaging products in the whole process from materials, product processing to waste disposal.
Appropriate packaging that does not cause pollution to human health and the environment.
Therefore, green packaging means saving resources and energy, avoiding the generation of waste, easy to recycle, recyclable and degradable, etc., which can meet the requirements of ecological environment protection.
Developed countries have required packaging to meet the “3R” and “1D” principles, namely Reduce (reduction), Reuse (reuse), Recycle (recycling), and Degradable (degradable).
With the continuous extension of the green concept, consumers put forward “4R1D” requirements for new packaging, adding Recover (energy regeneration) to the “3R1D” principle.
The so-called green packaging materials refer to packaging materials that can be recycled, recycled or degraded, do not cause waste of resources and do not cause pollution to the human body and the environment during the entire life cycle of the material.
Green packaging materials essentially cover both the meaning of environmental protection and resource regeneration, thus forming a closed ecological cycle.
As far as the packaging materials currently used in food are concerned, such as paper, plastic or paper-plastic composite materials, whether it is a green packaging is comprehensively judged from two aspects of resources and the environment.
A comprehensive comparison is made from resource utilization, manufacturing to post-use treatment.
Therefore, the technical system of green packaging should solve the problem of damage to the ecological environment during the whole process of packaging before and after use, research and find ideal green packaging technology, or develop and research corresponding green packaging products and methods according to different requirements of commodities.
The practical significance of advocating green packaging is to promote the establishment and improvement of the recycling and regeneration system of packaging resources.
So, packaging waste can be fully utilized, greatly reducing the pollution and damage to the ecological environment and at the same time greatly reducing the consumption of natural resources.
Introduction of Food Packaging
Food is the material basis for human survival and social development, the source of energy for people to engage in labor production and all activities and the eternal theme of national stability and social development.
With the progress and development of society, especially in the 21st century, people’s food and clothing problems are basically solved, and packaging is no longer a dispensable link for food itself, but an indispensable part.
Reasonable packaging of food can not only guarantee the quality of food to a certain extent, facilitate production, storage and transportation, but also promote product sales and increase commodity value.
It is an important link that cannot be ignored in any food production process.
As a comprehensive applied science, food packaging science involves basic sciences such as chemistry, biology, physics, packaging science, and marketing.
Food packaging engineering is a system engineering, which includes food engineering, mechanical mechanics engineering, chemical engineering, packaging materials engineering and social and humanistic engineering.
Therefore, we must first master the subject and technical knowledge related to food packaging as well as the ability and methods of comprehensively using relevant knowledge and technology for packaging operations.
Secondly, we should establish a standard system for evaluating the quality of food packaging.
How Can We Become Good At Making Food Packaging?
To know better about food packaging, one should first understand the main components and characteristics of food and the internal reactions that may occur during processing, including abiotic internal biochemical reactions and biological spoilage reaction mechanisms.
The main ingredients, especially the sensitive factors of nutrients such as fat, protein, and vitamins, including light, oxygen, temperature, microorganisms and physical and mechanical factors.
Only by mastering the biological, chemical and physical characteristics and sensitive factors of the packaged food and determining the protection conditions required by it can the packaging materials and packaging technology be correctly selected for packaging operations to achieve the protection function and properly prolong the shelf life of food.
There are many kinds of packaging materials with different performances.
Therefore, only by understanding the packaging performance of various packaging materials and containers can we choose according to the protection requirements of packaged food.
Reasonable cost packing material.
For example, foods that require high-temperature sterilization should be packaged with high-temperature resistant packaging materials, while low-temperature refrigerated foods should be packaged with low-temperature resistant materials.
For a given food, after selecting the appropriate packaging materials and containers, the most appropriate packaging technology should also be adopted.
The selection of packaging technology is closely related to packaging materials, as well as factors such as the market positioning of packaged food.
The same food can often use different packaging techniques to achieve the same or similar packaging requirements and effects, but the packaging costs are different.
For example, easily oxidized food can be packed in vacuum or air, or packed with a deoxidizer, but the latter has a higher packaging cost; sometimes in order to achieve the set packaging requirements and effects, specific packaging technologies must be used.
We can see different kinds of packaging around us in our daily lives. If you want more information about food packaging, please contact [email protected]
