The printing of packaging materials plays a very important role in the industry, and green packaging printing has become the goal of major manufacturers.Application Analysis And Research of Food Green Packaging
The printing of packaging materials is another important subject involved in green packaging. In particular, ink is composed of pigment, binder, solvent and auxiliary materials.
If the pigment contains heavy metals such as lead, chromium, pickaxe and mercury insoluble in water, this ink cannot be used for the printing of food packaging and children’s appliance packaging. Solvents containing acetone, toluene, methanol and some aromatic compounds and highly corrosive solvents should not be used.Application Analysis And Research of Food Green Packaging
As early as the 1960s, Guangdong Province has developed water-soluble liquid photosensitive resin, which can be used to manufacture water-based UV varnish and water-based UV ink, which can be cured and dried by UV irradiation. Application Analysis And Research of Food Green Packaging
During the drying process, the ultraviolet light source can be installed on the printing press, but it shall be covered and sealed to prevent burning human eyes. Application Analysis And Research of Food Green Packaging
At that time, we studied using black light tubes (i.e. 3-5 agricultural sterilization lamps) for liquid resin plate as light source, which can reduce the harm of ultraviolet light to human body, with low cost and simple process.Application Analysis And Research of Food Green Packaging
How to realize green packaging in food packaging enterprises
According to ISO14000 series standards, food packaging manufacturers must do the following work in order to realize green packaging.Application Analysis And Research of Food Green Packaging
The establishment of “environmental management system” (EMS) is the first step for food packaging enterprises to move towards green packaging, just as ISO9000 requires the establishment of “quality system” Same.Application Analysis And Research of Food Green Packaging
Its task is to formulate and implement environmental policies, plan environmental activities, implement environmental management, supervise and inspect. Application Analysis And Research of Food Green Packaging
The core elements of the management system include the company’s environmental policy, environmental planning, implementation and operation, inspection and correction and management review. The management system will ensure that enterprises achieve the goal of green packaging.
The environmental policies, objectives and activity plans formulated by the enterprise shall adapt to its own attributes, scale, production (activities).Application Analysis And Research of Food Green Packaging
Products and services’ impact on the environment, and have commitments to save resources, prevent pollution and comply with relevant laws and regulations.Application Analysis And Research of Food Green Packaging
According to ISO14000 requirements, Packaging enterprises must pass the “environmental certification” (EA) to ensure that they meet the requirements of iso14010-14019 standards. Quality certification focuses on the “self quality” of products, while environmental certification focuses on the “environmental quality” of products. Application Analysis And Research of Food Green Packaging
For food packaging manufacturers, it is only “saving resources, reducing pollution and recycling” It is far from enough.Application Analysis And Research of Food Green Packaging
Enterprises must establish EMS and pass the certification of national authorities. Some food packaging manufacturers in China have taken the lead in passing environmental certification.
Environmental label (EL) is commonly referred to as “green label”. In the future, three environmental labels launched by ISO will be implemented worldwide: type I, type II and type III environmental labels.Application Analysis And Research of Food Green Packaging
The type I mark specified in ISO14000 is called “ecological mark”, which depends on the ecological situation of each country, so there will be great differences between developed and underdeveloped countries. Application Analysis And Research of Food Green Packaging
Type II sign is the “information sign” of the enterprise’s “self declaration”. The enterprise discloses its environmental policies, environmental data and information to the society in the form of labels and accepts social supervision. Application Analysis And Research of Food Green Packaging
Type III mark is the environmental “quality mark” of products, which is marked with specific digital indicators and line segments at the same time, which is more intuitive and convenient.Application Analysis And Research of Food Green Packaging
Government agencies of various countries will recommend products and packages with environmental labels to users or consumers.Application Analysis And Research of Food Green Packaging
The evaluation results will help packaging enterprises save resources, prevent pollution, make use of new technologies and new management systems, so as to take them to a new level.Application Analysis And Research of Food Green Packaging
The so-called life cycle refers to the whole process of “material mining → processing and manufacturing → circulation and use → recycling → waste disposal” and “coming from the earth and returning to the earth”. Application Analysis And Research of Food Green Packaging
It is also translated as “ecological cycle” or “ecosystem”. To manufacture any kind of product, we must first “input” materials, energy, manpower, etc., and then “output” Products. The “products” of this industry must include needed products, waste, excreta, etc. Application Analysis And Research of Food Green Packaging
Therefore, ISO14000 requires packaging enterprises to carry out the above “whole process” life cycle assessment (LCA) of packaging products, so as to control the “whole process”, adopt “zero pollution” or “clean process”, produce “green products” and meet the standard of green packaging.Application Analysis And Research of Food Green Packaging
At present, the world generally attaches importance to environmental protection. Therefore, there are many new specific provisions on food packaging materials in the world. Application Analysis And Research of Food Green Packaging
Moreover, our main goal of packaging food is to preserve quality and freshness.Application Analysis And Research of Food Green Packaging
Avoid environmental pollution and have a certain beauty. Therefore, the development and application of green packaging will be the theme of food packaging now and in the future.Application Analysis And Research of Food Green Packaging
