Abstract
The process of producing degradable green preserving plastic bag consists of three steps, including drawing, compounding and bag making. The drawing step and the bag making step are the same as that of traditional process, and the compounding step is completed in a paper-plastic compounding machine. The production process includes setting plastic wire reels on the holders, combing, extruding hot plastic film with an extruder, adhering with paper from the paper roll of compounding machine, and extruding in a compounding roll to adhere to form the degradable green preserving plastic bag. The technological process is simple, high in efficiency and low in production cost.
Description
(1) technical field
The present invention relates to fresh-keeping degradative plastic bag of a kind of environment-friendly and green and production method thereof.
(2) background technology
Existing polyethylene freshness protection package, with the spontaneous controlled-atmosphere is that theoretical basis is developed, it only is by selecting the thickness of PE bag, the air-tightness that is the PE bag reaches certain fresh-keeping effect, and fail to solve because fruit matter that factors such as illumination, germ, enzyme, moisture cause and fruit look become bad problem, in addition, in this common PE preservation process, the often long-pending full globule of its inwall, make fruit near the inwall browning that very easily decolours, even rot, so the fresh-keeping effect of existing common PE freshness protection package is very limited.
(3) summary of the invention
The object of the present invention is to provide a kind of environmental protection green packaging fresh-keeping degradation plastic bag and production method thereof.
The technical scheme that adopts is:
Environmental protection green packaging fresh-keeping degradation plastic bag of the present invention, it is staggered bonding to it is characterized in that the packaging bag skin is moulded silk one-tenth prismatic.
The production method of environmental protection green packaging fresh-keeping degradation plastic bag of the present invention is made up of wire drawing, compound and bag three process.Its wire drawing, bag operation are identical with wire drawing, the bag operation of conventional production methods, its compound working procedure carries out compound with the compound unit of paper, it is characterized in that: will mould a reel extension earlier and ride on the silk tube frame, about mould silk through left and right sides wire feed frame to about comb combine the back and become prismatic to interlock to pass to mould a locating plate, again by moulding the tooled joint of a pressure roller and compound drive roll, the hot sticky film of extruding through the thermoplastic film extruder is bonding with the paper of sending here from the paper web roller of compound main frame rear end with it again, and, promptly make the fresh-keeping degradative plastic bag of environment-friendly and green through composite roll extruding applying.
Production method of the present invention has following benefit: 1, owing to directly compound with paper with moulding silk, omitted time-consuming knitting process, technology is greatly simplified, also improved work efficiency simultaneously, the highest recombination velocity of this machine per minute reaches 60 meters; 2, because this method device therefor has been save braider fully, so a manufacturing line can be saved ten thousand yuan of investment 60-100, the manpower ratio is 1: 10 simultaneously, and the electric energy ratio is 1: 100, and the plant area ratio is 1: 80, can greatly reduce production costs.
(4) specific embodiment
A kind of environmental protection green packaging fresh-keeping degradation plastic bag of the present invention, the shape and structure of its shape and structure and traditional paper plastic combined package bag is roughly the same, and it is staggered bonding to it is characterized in that its skin is moulded silk one-tenth prismatic.
The production method of a kind of environmental protection green packaging fresh-keeping degradation plastic bag of the present invention is described as follows: wire drawing on the production method, compound and bag three process composition.Wherein wire drawing, bag operation are identical with wire drawing, the bag operation of traditional method for producing paper plastic combined package bag, organize the wire drawing unit that adopts Pingyang, Zhejiang tools factory to produce mutually as wire drawing in wire-drawing process, it pulls into plastic film with plastic raw materials (as polypropylene 2410) earlier, again film is cut into flat filament, at last with the flat filament reel.
Claims (2)
