Laser technology serves as a kind of burgeoning technology, be applied extensively a few this years at metallic cut, solder, the product makes the numerous production field such as cut of stiletto of sculpture of mark, handicraft, circuit board, semiconductor. As industrial laser life is lengthened ceaselessly, cost is reduced stage by stage, laser technology can enter more treatment fields, become important process instrumentation. Technology of laser of the application in treatment of flexible package bag also has wide perspective.

Flexible package bag is opened for convenient client pack, use 2 kinds of means to make commonly rip a mouth easily. One kind is to wrapping bagging at the same time or both sides is strong dozen rip a mouth easily, client edge is ripped to the gap that drive pull open pack; Another kind is to be in those who wrap bagging at the same time or both sides uses side of tooth form of cut of tooth form knife, the client can be ripped by tooth form edge pull open pack. These two kinds rip a mouth easily to all be formed for mechanical punch or cut, have two inadequacy: Often should maintain above all change film is provided, cutting tool; The trend of the line is torn off after incontrollable client is torn apart next, often cannot along the avulsion of products plan the line is torn apart, a lot of people have when tearing apart flexible package will bag is whole rip bad, the unpleasantness of packing leak is experienced. Flexible package bag adds the packing form of slide fastener to have higher demand to ripping buccal avulsion easily to move toward, once tear off direction not to get control, rip bad slide fastener very easily, destroy function of slide fastener bag. Euramerican developed country begins nearly two years to use laser technology cut to rip a line easily, this ripped buccal treatment easily to provide new method for flexible package bag. This kind of means is rip a line easily to be in even cut to give with what laser light beam is designing deep only the filament of a certain number of micron, what this line destroyed compound film is outer pack, reservation lining is packed, both neither destroys the function that pack, the OK and regular edge when making tear off again rips a line easily to tear apart. Because this kind machined means to go to the lavatory greatly,the client is used, go up very quickly to apply extensively in the flexible package bag of Euramerican developed country.

Zhongshan is new limited company of industry of automation of grand course of study takes the lead in developing successful laser to rip line cut system easily in home, and oneself apply in manufacturer of several large flexible package. This system setup that they develop cuts machine or rewinding machine at cent, use cent to cut machine or rewinding machine to put roll, control of correct an error, tension. Close roll wait for a function, implementation is made coiling before bag had hit on film rip a line easily, achieve the goal with one multi-purpose machine.
