Summary of the invention

Main purpose of the present invention is to provide the preparation method of the compound form bag of a kind of paper, its production process continuity height, and the production efficiency height, and the window dimension of product is unrestricted, and cost of manufacture is low.

In order to reach above-mentioned purpose, solution of the present invention is:

The preparation method of the compound form bag of a kind of paper comprises the steps: that (1) goes out the form of preset width at the desired location longitudinally cutting of paper; (2) remove the zone of corresponding form at a side surface of plastic sheeting, the coating glue; (3) paper is relative laminated with the one side of plastic sheeting coating glue, form composite; (4) with the form bag of required specification of aforementioned composite material forming and shape.

In the above-mentioned steps (1), paper being placed on the cutting apparatus, is the preset width of form with the distance adjustment of two cutting knifes.

In the above-mentioned steps (2), by an anilox roll that is placed in the glue groove, this anilox roll is provided with no reticulate pattern district in the zone of corresponding form with plastic sheeting.

After adopting such scheme, the present invention has following improvement:

(1) adopts cutting apparatus that paper is processed, dissect out required form, so the size of form only need change the distance of two cutting knifes, volume influence to cutting apparatus is little, and need not the specification of corresponding more exchange device, but the size random variation of required form, and cost of manufacture do not had influence;

(2) through the paper of cutting apparatus, clout is cut long paper paper slip, and because size is bigger, therefore packaging bag or other purposes that also can be used for making little bag item as utilizing once more, can not cause waste;

(3) as long as guarantee the continuous transmission of paper, cutting apparatus can dissect continuously to paper, and working (machining) efficiency improves greatly;

(4) plastic sheeting is whole laminated with paper earlier, cuts then, moulding, saves the operation of in the existing procedure plastic sheeting being cut into slices, and need not to paste separately window, reduces manufacturing procedure, enhances productivity;

(5) in whole process of production, required all is conventional equipment, and price is relatively low, and paper can be realized continuous transmission in the production process, need not to wait for, and production process continuity height, thus enhance productivity greatly.
