Believe everyone around to already had the personal experience of the environmental problem.Environmental protection has become an inevitable and imminent and urgent problem.And the environmental protection is the protection of human beings rely on to their homes, is to protect human oneself.
In the field of fabrication, along with the hairpin quantity increases gradually, abandoned CARDS is more and more.More worryingly, by far the most CARDS are using PVC material as card, the card discarded after will become a kind of "white pollution", cause serious harm to the environment.As a result, a card with environmental properties will be vividly portrayed. 
So what kind of card is environmental protection?This request in the model selection of the material should not only consider the strength of materials, features, factors such as cost and resources;To consider, in the process of manufacture and use recycled total burden on the earth's environment is the smallest, whether it is helpful to health.Therefore environmental protection material should have one or more of the following four characteristics: 1, long service life, reduce the frequency of updates, reduce the request of limited resources;2, can be recycled, avoid the disposable use, so as to extend the use of material cycle;After 3, material waste by artificial processing does not produce toxic or harmful substances;4, material waste after natural degradation into harmless substances in the short run.Besides materials, environmental protection, the manufacturing process of card must be environmental protection, such as product processing required less energy consumption, cause no discharge of poisonous and harmful material processing and so on. 
Fabrication materials currently on the market has two kinds: polyolefins (including PVC, ABS) and polyester (including PC, PET, PETG).Following a brief introduction to the characteristics of several kinds of materials.
PVC, PVC, its mechanical properties and electrical insulation good, transparent, flame retardant, resistance to chemical corrosion, low price, is good comprehensive properties of a kind of plastic.Defect is the difference in thermal stability, easy to decompose release hydrogen chloride, must add stabilizer to processing.Prone to brittle at low temperatures, and often join modifier to improve the toughness.Card with PVC also joined a certain amount of chlorine vinegar resins to reduce the vicat temperature, thus improving laminated eligibility.
ABS acrylonitrile - butadiene - styrene copolymer, has the characteristics of tenacity, qualitative hard, rigid, heat resistance, impact resistance, high surface hardness, size stability, low temperature - there are still quite the impact strength of 40 ℃.But the weather especially uv resistance is poorer, outdoor use easy ageing.Due to the softening temperature is higher, ABS is greater than 90 ℃, so the card with the ABS mixed with certain proportion of PVC in order to reduce its softening temperature so that the laminated.
PC, polycarbonate, high light transmittance, low water absorption, impact resistance, good toughness, creep, products have size stability.Good heat resistance and cold resistance.Glass transition temperature (149-150 ℃) and heat deformation temperature (135 ℃) are higher, laminated need high temperature to the calender.Due to the surface of the PC card is not easy to do personal, this greatly limits the application of PC material in terms of bank card.
PET, polyethylene terephthalate, with excellent mechanical properties, high rigidity, high hardness, small water imbibition, good dimensional stability, good toughness, impact resistance, friction resistance, creep resistance, good chemical resistance. 
PETG, polyethylene terephthalate glycol - 1, 4 - ring adipic methyl ester, a common understanding for a PET to add 1, 4 - ring adipic methanol to modification and PETG.PETG has high hardness, excellent toughness, good low temperature toughness, high transparency, easy to processing molding, coloring ability, ageing resistance and chemical resistance, belongs to a new generation of environmental protection material.Environmental performance of PETG is mainly generate only into water and carbon dioxide when burnt.As early as 1988, visa credit card organization will PETG CARDS base material as its credit card environmental protection material.PETG has passed the American FDA standards on food contact, can be used in food packaging, personal care products packaging, medicine and health care equipment, etc, can also be used for electronics packaging.In Europe, the United States, Japan, PETG materials are widely used in the electronic payment and identity documents.

How environmental characteristics of these fabrication materials, according to the characteristics of the environmental protection material to them to make the comparison of an environmental characteristics, the following table. Obviously, PETG is currently the most environmental protection card material. Jie DE wanda in line with the strong sense of responsibility, environmental protection to market a card with environmental characteristics.This card from the core layer substrate to PETG material should be used in thin film on the surface, the PETG material is also China's officially designated the second generation id card materials.From the Angle of environmental protection and the card body performance under pure PETG CARDS and a detailed comparison between pure PVC card.Table 2 pure PVC card compared with pure PETG CARDSAs shown in the table above, PETG CARDS from processing, use to recycling has the excellent properties of PVC card cannot match.By the fabrication material development, at present, the PETG materials included various fabrication materials are made from oil and other chemical raw materials, do not have fast natural degradation ability, it would take a long time of this kind of material waste can be degraded completely in the nature.Therefore, in order to plant material made of plastic has, first emerged in the market and corn-based polylactic acid (PLA) have attracted the most attention. PLA is made from corn oil or polyester acid extracted from corn.PLA from the look and feel, there is no difference with PVC material card, and have very similar life and printing features.This material when making CARDS can save 35% energy and 25% less greenhouse gas emissions, and it can be natural degradation, rapidly buried in about three months to be able to fully biodegradable, does not produce toxins incineration is destroyed.Unfortunately now will PLA for mass production of CARDS has certain difficulty, but look at the current science and technology development speed, believe that people will soon have a card made from corn. As a pioneer card manufacturing and service sectors huang shijie DE wanda gold card co., LTD., has been to environmental protection as a major corporate responsibility, constantly trying to explore on environment and product environmental protection, and adhere to provide customers with the most environmentally friendly products, to protect human survival environment clean and safe to make new contributions.
