Nowadays, Pack aging have become necessary and familiar with us, packaging presents in our work, our life and its essential increases by the time. What is packaging? With the attractive shape and different sizes, packaging are used to contain and protect the products from the time they are made to the time they are used by the consumers.
  Like this, when buying a product, consumers not only spend more money for their products but also for their packaging. In some cases, these spending up to 30% or more than 30% of total purchasing. However, the consumers still willing to spend. Why?
  The answer consists on the following functions of packaging:
  Firstly, packaging are used to contain the products to keep them not to be leaked out, lost, unchanged and deformed.
  Secondly, packaging are used to protect products to keep them not to be broken in the disadvantage of environment such as degree, air, humidity and light.
  Thirdly, packaging can also be used to present, describe, advertise for the products. There are guides to use, expire day, describe the structure of products and the special instructions. These elements have been presented attractively.
  From the three functions of packaging such as containing, protection, presentation and advertisement, the packaging producers have to think more about their production.
  To supply the containing function of packaging, they are divided into three types:
  First type of packaging: packaging directly contact with products such as can, glass bottle, carton boxes, plastic packing.
  Second type: packaging are used to contain products which are packed by the first type of packaging, for example carton boxes.
  Third type: the containers which contain the products which are packed by second type of packaging.
  Base on the classification of packaging, the packaging producers will chose and determine which kind of technology and equipment they will apply for their production. Notice that, this starter is very important.
  To supply the protection function of the packaging and to protect the products inside to have the original quality as like as it have just been produced, products will be lasted longer. Depending on each specific case, we should pay attention in following properties:
    * Stable mechanics
    * Steady contain
    * Transparent
    * Steam separation ability
    * Stable on water
    * Smell keeping
    * Oxygen separation
    * Degree ability
    * Light ability
    * Safety for children and elder
  The equipment, technology and raw materials effected to these above properties.
  For this reason, advertising of packaging products need to be designed to made it more attractive, to stand out the products inside and it can be distinguished easily between a product of this producer to the other one . Packing must be attractive and good quality. Colors, shapes must be designed to supply the requirement of producers. Colors are not fade by time, light and it is similar in different printing times. When design packaging have to present all the information of the products inside to supply the requirement of producers and consumers such as date of production, expire day, ingredients, guides to use… In some cases, these requirements are very important for instance packaging of pharmaceutical products.
 In short, packaging producers have to consider carefully to decide how to make there are packaging suitable with the products inside and increasing the value of the products. Moreover, packaging have to economic, this means that with a minimun of raw materials, we can produce the maximum of products. Packing have to fix, finishing goods process is easy, spend less time, decrease the colors but get the effect of presentation….
 We should remember one thing that packaging is not fixed, often change, raw materials require for the new production methods and for this reason we need to have new equipments. The more we change the new equipments the more we produce good quality products.
 However, in the future packaging Industry have to deal with the difficulty challenge in technology is that packaging trend to be produced thinner, lighter, safer for environment, faster packing productivity, better qualities printing while the raw materials used to produce packaging become rare, customers’s requirement become difficulty and at present it is difficult to fulfill the customers requirements and at the same time regulation of Government is strict.
  Answered the question about the trend of Global packaging, Mr Herry Debney - President of Australia Packaging Board said: “Reduce the cost; shorten production process; handy packing; service life is lasted; advanced distribution system and manage effectively the distribution channel; packaging is considered to be as a tool to advertise; interesting in the environment; Electronic Business and Globalization” 
  Reducing production cost is the most important problem that the packaging producers have to aware of it. Nowadays, we cannot keep the business going up without continuing to improve the effective of business and services, needs to find out the best way to supply to the customers and bring them the most benefit.
  Considering packaging is a tool to marketing is also an important trend that we should pay attention. Changing the habit to buy goods at the supper market instead of buying them at small store is also influence so much to the designing of packaging. In average, there are about 30.000 products which arranged at the supper market and 2/3 of these products are decided to bought at the counter by customers. Every customer plan to buy 10 products when shopping in the supper market but then they buy 19 products, every customer get 9 seconds to decide to buy goods. For this reason, outstanding of packaging, trade mark of products play an important role in decide for the customers to buy goods. The trade mark mangers realize more important of international trade mark and national mark. Therefore, the packaging producers have to apply for international standard in production and distribution of packaging. The customers expect from the packaging producers to expend their market not only on nationwide but also on the worldwide. 
  The market and scope are extended, diversified goods. As a result, it is important to need the combination of human in harmony and flexible. Moreover, the relation between packaging producers and consumers become more important.
