Abstract
The invention relates to the technical field of bag making process, and particularly relates to a membrane blowing technology and a membrane. Through the matching improvement of membranes and the improvement of the production technology, the safety of courier bags in the transportation process can be greatly enhanced.
Description
Technical field
The present invention relates to bag maker technology field, relate in particular to a kind of film-blowing process and a kind of coating materials.
Background technology
Courier bag refers to that express delivery industry transports the sack that the packagings such as file, document, data, goods are used.What use was more at present is the plastics courier bag made from polythene material, has cost low, easy to use, the feature that water resistance is good.
The coating materials quality that courier bag above existing market is used is uneven, does not also reach the desired requirement of client when client needs glue to have destructiveness to courier bag, causes the important item of courier bag the inside dress to have loss hidden danger.
Summary of the invention
The object of the invention is to provides a kind of film-blowing process and a kind of coating materials for the deficiencies in the prior art, greatly improves the security of courier bag in transportation.
For achieving the above object, the present invention adopts following technical scheme.
A film-blowing process, it comprises following processing step:
The first step, adds dry coating materials in hopper by inflation film manufacturing machine, leans on the weight of particle itself to enter screw rod from hopper, and after material contacts with screw thread slant edge, the slant edge of rotation, in the face of the vertical thrust of plastics, is passed particle forward;
Second step, in passing process, due to the friction between particle and screw rod, particle and machine barrel and interparticle collision friction, also because making particle, barrel external heat progressively melts simultaneously, the particle of melting after head filters decontamination from die head die orifice out, cooling through vane again, then inflation batches finished film is rolled into cylinder through steady bubble frame, collapser, carry-over pinch rolls;
The 3rd step, by Bag Making Machine by the finished film of having blown bag after rigging machine doubling, and gluing;
Above-mentioned coating materials is prepared by weight by following composition:
Linea low density PE raw material 0,042 75%
High pressure P E raw material 330E 23.5%
80179G opening agent 1.5%;
Above-mentioned opening agent is not containing slipping agent.
A coating materials, described coating materials is prepared by weight by following composition:
Linea low density PE raw material 0,042 75%
High pressure P E raw material 330E 23.5%
80179G opening agent 1.5%;
Above-mentioned opening agent is not containing slipping agent.
Beneficial effect of the present invention is: a kind of film-blowing process of the present invention and a kind of coating materials, improve the security of courier bag in transportation greatly.
The specific embodiment
Embodiment 1, a kind of film-blowing process, and it comprises following processing step:
The first step, adds dry coating materials in hopper by inflation film manufacturing machine, leans on the weight of particle itself to enter screw rod from hopper, and after material contacts with screw thread slant edge, the slant edge of rotation, in the face of the vertical thrust of plastics, is passed particle forward;
Second step, in passing process, due to the friction between particle and screw rod, particle and machine barrel and interparticle collision friction, also because making particle, barrel external heat progressively melts simultaneously, the particle of melting after head filters decontamination from die head die orifice out, cooling through vane again, then inflation batches finished film is rolled into cylinder through steady bubble frame, collapser, carry-over pinch rolls;
The 3rd step, by Bag Making Machine by the finished film of having blown bag after rigging machine doubling, and gluing;
Above-mentioned coating materials is prepared by weight by following composition:
Linea low density PE raw material 0,042 75%
High pressure P E raw material 330E 23.5%
80179G opening agent 1.5%;
Above-mentioned opening agent is not containing slipping agent.
Embodiment 2, a kind of coating materials, and described coating materials is prepared by weight by following composition:
Linea low density PE raw material 0,042 75%
High pressure P E raw material 330E 23.5%
80179G opening agent 1.5%;
Above-mentioned opening agent is not containing slipping agent.
A kind of film-blowing process described in embodiment 1 and embodiment 2 and a kind of coating materials, by the proportioning to coating materials, improve, and the improvement of production technology, solved the destructiveness of existing glue to coating materials, and glue and gum waybill will out, improve the security of the transportation article of courier bag to the destructive effect of coating materials in 10 seconds.
The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
