Development of Packaging Bag
It is obvious that packaging bags experienced four phases: original bags stage, the stage of large bags, sachets stage, and it gradually enters a new stage of the environmental (green) bags. With the development of the commodity economy, the marketability of the packaging itself is also growing significantly, it has become no longer a special product attached to the commodity production, and it is a kind of widely used products which cannot be separated from all goods. State scientists have developed environmentally friendly plastic bags which are made of electrolyte, this environmentally friendly plastic bag cannot only be decomposed harmlessly, and it can dissolve in water. According to the scientists' explanations, the products made of polymer plastic materials in common life have to be completely decomposed for hundreds of years, so it will exist on earth for centuries. According to the actual figures, 80% of the used plastic bags are finally transported to the heap with the ordinary garbage, while only seven percent of plastics can be recycled and used. This new environmentally friendly plastic bags will not only release harmful substances in the decomposition process, but even broken down into natural substances which is insect's favorite, and it does great help to protect the natural environment.
The Principle of the Vacuum Packaging Bag
The principle of vacuum packaging is very simple. The main reason of food's mold and rot deterioration is caused by microbial activity and survival of micro-organisms (such as mold and yeast) needs oxygen, vacuum packaging takes use of this principle which deprives the oxygen in the bag to make food intracellular microbial lose "living environment". At the same time, it also prevents the food tasting differently and deterioration due to the oxidation of food, in order to achieve the results of a longer period time of storage and preservation of food.
Common Features of Vacuum Bags

Vacuum packaging is mostly made of film material, and of course, bottle and can are also used. The film material used in food vacuum packaging can ensure that the aspects of various food packaging, aesthetic, economic can achieve the best state. Meanwhile, food vacuum packaging has higher requirements on light-blocking and stability of material.
