The principle of the body vacuum packaging machine is: the use of low viscosity composite film, the material is put on the traybox or film of the lower template, in vacuum state, the heat generated by the heating plate is sent to the vacuum chamber throughthe air outlet, to the low viscosity composite film instant whole body heating, composite together, to achieve the effect ofvacuum packaging. This kind of packaging is the film heating softening and then shrink packaging, so there is no packaging withsharp corners, hard prickly items will Pierce the phenomenon of the film. This kind of packing has no breakage rate.There are two modes of this kind of packaging: disposable box type, gold card (this kind of packaging, can increase the attractivebeauty, three-dimensional sense is particularly strong)
