ABSTRACT

The packing machinery is one of national economy important industrial,undertakes the lives of the people, is prospering the city andcountryside market, expanded exportation bringing in foreign exchangeincome, for the national construction accumulated capital importanttask, to promotes the national economy coordinated development andrealizes the overall strategic target relations which the nationaleconomy and the society develops to be extremely close. Since thereform and open policy, our country packing profession has obtainedthe considerable development, the appearance has had the huge change,already forms has the suitable scale and the certainly economicallevel, the class is complete, can basically satisfy the domesticdemand also to have the certainly international competition abilitythe production system. May say like this has not packed the machinerythe development not to have the diverse product which today prospers. Take electronic technology, computer technology and so on asrepresentative's high-tech swift and violent development, not onlyurged national's living standard to enhance day by day, as well as theproduct turned to a new generation cyclical reducing, moreover causedthe mechanical product the performance unceasing enhancement and theconsummation. This especially in the packing mechanical aspect, thecommodity life enhancement already could not meet people's needs, whatnow are more was advocates the spiritual civilization the wealth. Thepeople have not liked 80's such only to strive for to fill the belly,how do we now pay great attention to pursuing each kind of food thehygiene condition? Whether facilitates quickly? Also some point alsois most important - food outside wrapping. Ancient cloud: "Beautifulenough to eat". Said with the present popular speech that, "Saw thefood attractive outside wrapping can cause person's mood to be happy,thus causes the appetite also to be able to increase." This oursubject pulled closer is away from. Now the market uses most packingtype is trilateral seals the bag which seals with the center.
