Description
Technical field
The present invention relates to a kind of composition of manufacture method and a kind of paper wood film of paper wood film.
Background technology
Paper food container is for avoiding liquid infiltration paper wood, conventionally in surfaces externally and internally coated with a plastics film processing, to reach waterproof effect, and known film is used polyethylene (PE) for main component conventionally, polyethylene mobility is good, easily be coated in fifty-fifty on paper wood, but, polyethylene heat resisting temperature only terminates in approximately 60 ℃, only can be applicable to cold drink, if splendid attire hot drink, film may decompose and disengage toxicant, cause content contaminated, in addition, for avoiding high energy to cause film to decompose, the paper container of the film take polyethylene as main component cannot be with heating using microwave.
On the other hand, for overcoming above-mentioned shortcoming, there is the paper container film of minority to adopt polypropylene (PP) as raw material, polypropylene heat resisting temperature can reach 135 ℃ of left and right, enough splendid attire hot drinks, also can carry out heating using microwave, but, polypropylene mobility is very poor, in the time of film operation, polypropylene meets air and the shaping of hardening in the process of coating that flows, therefore, cannot successfully pp material be covered with equably to paper wood surface and be shaped, or need more substantial raw material to carry out film, and the too film streaking of rapid hardening, easily produce the block of multiple density unevenness, reduce yield, if reinforcement quality and carry out repeatedly film, not only gain in weight, also improved cost.
Summary of the invention
Main purpose of the present invention is the composition of manufacture method and a kind of paper wood film that a kind of paper wood film is provided, so that preferably heat-resisting effect to be provided, and has preferably yield and product quality.
For reaching above-mentioned purpose, the invention provides a kind of manufacture method of paper wood film, comprise following steps:
(a) a first raw material is given to heating and melting and stirring in mixing mode, and first raw material is granulated and become one second raw material, wherein the composition of this first raw material comprises polypropylene (PP) and polyethylene (PE);
(b) one first raw material is mixed to also heating and melting and stirring with this second raw material, wherein this first raw material is polypropylene (PP);
(c) raw material (b) step having been stirred is granulated again;
(d) the heating raw materials melting through granulating again by (c) step;
(e) (d) step is formed to film through the raw material of heating and melting through extruder extrusion;
(f) this film is coated in to a paper wood surface;
Wherein, (a) in step, this first raw material comprises 80～90% polypropylene (PP) and 10～20% polyethylene (PE), and (b) the first raw material of step and the ratio of the second raw material are 80～92: 8～20.
The present invention more provides a kind of composition of paper wood film, comprise the film that a paper wood and is coated in this paper wood surface, wherein one just raw material through mixing with granulate again after become one second raw material, this second raw material mixes with one first raw material after also heating and melting stirring again, through granulating again, heating and melting forms this film through extruder extrusion again, wherein this first raw material is polypropylene (PP), and the composition of this first raw material comprises polypropylene (PP) and polyethylene (PE);
Wherein, this first raw material comprises 80～90% polypropylene (PP) and 10～20% polyethylene (PE), and the ratio of the first raw material and the second raw material is 80～92: 8～20.
The invention has the advantages that:
Paper wood film provided by the invention can be born higher temperature, therefore can splendid attire hot drink, and more flowability, can be distributed in more equably paper wood surface, and then improve quality and improve yield.
Accompanying drawing explanation
Fig. 1 is manufacturing flow chart of the present invention.
Reference numeral
The 1 first raw material 2 second raw material P1 just mixing P3 of raw material P2 S1 the mixings S2 heating and melting S3 that granulates again stir S4 and granulate S5 heating and melting S6 extruder extrusion S7 formation film S8 coating film in paper wood again
The specific embodiment
Below only with embodiment, the enforcement aspect that the present invention is possible is described, so not in order to limit the category of institute of the present invention wish protection, close first chat bright.
Please refer to Fig. 1, the invention provides a kind of manufacture method of paper wood film, comprise following steps:
(a) by one just raw material P1 give heating and melting and stirring in mixing P2 mode, and the first raw material P3 that granulates is again become to one second raw material 2, wherein the composition of this first raw material P1 comprises polypropylene (PP) and polyethylene (PE);
(b) one first raw material 1 mixed to S1 heating and melting S2 with one second raw material 2 and stir S3, wherein this first raw material 1 is polypropylene (PP);
(c) raw material (b) step the having been stirred S4 that granulates again;
(d) the heating raw materials melting S5 through granulating again by (c) step;
(e) (d) step is formed to film S7 through the raw material of heating and melting through extruder extrusion S6;
(f) coating film is in paper wood S8: this film is coated in to a paper wood surface.
Wherein, (a) in step, this first raw material comprises 80～90% polypropylene (PP) and 10～20% polyethylene (PE), and (b) the first raw material of step and the ratio of the second raw material are 80～92: 8～20.
Therefore, the present invention also provides a kind of composition of paper wood film, comprise the film that a paper wood and is coated in this paper wood surface, wherein one just raw material through mixing with granulate again after become one second raw material, this second raw material mixes with one first raw material after also heating and melting stirring again, through granulating again, heating and melting forms this film through extruder extrusion again, wherein this first raw material is polypropylene (PP), and the composition of this first raw material comprises polypropylene (PP) and polyethylene (PE).Wherein, this first raw material comprises 80～90% polypropylene (PP) and 10～20% polyethylene (PE), and the ratio of the first raw material and the second raw material is 80～92: 8～20.
By for the first time mixing with again granulate process, first raw material evenly can be formed to the second raw material, again through for the second time mixing with again granulate process, this first raw material can fully mix and form uniform single-grained structure with this second raw material, and because making mobility, the interpolation of the second raw material promotes, MI value (Melt flow index) increases, while carrying out film operation, single-grained structure can be scattered on paper wood fast and fifty-fifty, each single-grained structure composition is even, while forming film structure, quality is evenly difficult for producing defective products, the most important thing is, this film heat resisting temperature is high compared with located by prior art, energy splendid attire hot drink, hot soup and can not disengage toxin because of decomposes, health risk.
In addition, because polyethylene cannot directly mix with polypropylene, therefore the present invention utilizes the mixing of twice specific blend ratio, make polyethylene can fully mix with polypropylene and be evenly distributed, therefore, made film has good mobility and yield, and polyethylene after calculating to account for overall ratio considerably low, significantly lower the risk of disengaging toxin after heating.
In sum, the composition of the manufacture method of paper wood film provided by the invention and paper wood film, energy is high temperature resistant and explain toxin compared with being difficult for because splendid attire hot drink divides, and it is good mobility (MI value) that film material has compared with located by prior art, therefore can be covered with more equably paper wood, and slowing down firm time, finished product has lighter weight and preferably yield and quality, real in having progressive effect.
