Description
Technical field
The present invention relates to heat-shrinkable film technology fields, and in particular to a kind of biodegradable POF heat shrink films and its system
Preparation Method.
Background technology
POF heat shrink films are the abbreviations of bidirection stretching polyolefine shrink film, it is that one kind is current uses most extensively in the world,
The novel environment friendly shrink film quickly grown.The product is using three layers of special process for melting co-extrusion of advanced biaxial tension.Production
Provide that the high grade of transparency, high shrinkage, high tenacity, high heat sealability, antistatic, cold resistance is excellent, safe and reliable soft receipts
Contracting film.It is widely used in food, cosmetics, gift, drug, stationery, toy, audio-visual product, electronics, woodwork, plastic cement five
Gold, the outer packing of the every profession and trades product such as daily necessities and collective type packaging.
POF heat shrink films are that preservation and strap also produce more serious problem while to facilitate, the most prominent
" white pollution " surely belonged to caused by POF heat shrink films, due to the characteristic of POF heat shrink films itself, by after discarded its
Decades even upper century-old all without putrefactions can be retained.
Invention content
To solve the above problems, the present invention proposes a kind of biodegradable POF heat shrink films and preparation method thereof, to protect
The discarded POF heat shrink films of card can fast degraded biologically, avoid it from polluting destruction to ecological environment.
Technical solution of the present invention：
A kind of biodegradable POF heat shrink films, it includes heat shrink films ontology, and the heat shrink films ontology includes successively
The trilamellar membrane of fitting is laminated；Described first, third tunic is made of the raw material of following weight：Ternary polymerized polypropylene 88-
95%, opening agent 2-5%, degradable masterbatch 2-5%；Second tunic is made of the raw material of following weight：It is linear low
Density polyethylene 88-95%, slipping agent 2-5%, degradable masterbatch 2-5%.
Since the percentage of the degradable masterbatch in trilamellar membrane material is 2-5%, degradable masterbatch is in this kind of content model
It when enclosing interior, is easy, in induced chemical reaction under light illumination, to generate free radicals chain reaction, by the first tunic inward portion solution, divide
Solution is thoroughly and speed is fast, and short the time required to decomposing, which achieves the rapidly and thoroughly degradations of POF heat shrink films.According to experiment
As a result, the biodegradable POF heat shrink films provided in the present invention, can drop or so the latter moon completely in discarded
Solution.
Above-mentioned technical proposal is improved further and is refined, the heat shrink films ontology is by three-layer co-extruded inflation film manufacturing machine
Disposable three-layer co-extruded molding is easy to process quick.
Above-mentioned technical proposal is improved further and is refined, the thickness of the first tunic accounts for heat shrink films body thickness
10-20%, the thickness of the second tunic account for the 60-80% of heat shrink films body thickness, and the thickness of third tunic accounts for heat shrink films sheet
The 10-20% of body thickness.
Above-mentioned technical proposal is improved further and is refined, the mixing of the opening agent silica and polyethylene
Body.
Above-mentioned technical proposal is improved further and is refined, the lubricant be fluoropolymer additive with
The mixture of polyethylene.
A kind of preparation method of biodegradable POF heat shrink films, includes the following steps：
（1）Raw material is weighed according to above-mentioned parts by weight.
（2）Ternary polymerized polypropylene, the 2- of 88-95% are separately added into corresponding two hoppers of three-layer co-extruded inflation film manufacturing machine
5% opening agent, the degradable masterbatch of 2-5%, the interior linear low density polyethylene that 88-95% is added of a corresponding hopper,
The slipping agent of 2-5%, the degradable masterbatch of 2-5%.
（3）Start the disposably three-layer co-extruded molding of three-layer co-extruded inflation film manufacturing machine, heat shrink films ontology is made.
（4）Membrane body is shunk through measuring thickness, winding, cutting and rewinding, is packaged into finished product heat shrink films.
The method have the advantages that reasonable design, simple in structure, due to dividing in the trilamellar membrane material for constituting POF heat shrink films
The degradable masterbatch of other 2-5% can realize the rapidly and thoroughly degradation of POF heat shrink films, it is avoided to make ecological environment
It is destroyed at pollution.
Description of the drawings
Fig. 1 is the structural schematic diagram of biodegradable POF heat shrink films.
First 01 second tunic of tunic, 02 third tunic 03 in figure.
Specific implementation mode
As shown, a kind of biodegradable POF heat shrink films, it includes heat shrink films ontology, the thermal contraction
