Description
Technical field
The present invention relates to packing film field, particularly a kind of food grade film and production method thereof.
Background technology
Current food packaging industry says that the packaging base material film quantity needed is large, kind is many, adopts the film of single raw material production to be difficult to adapt to the packing instructions of Special food.Trace it to its cause, although producer's production technique of mainly respectively producing plastic raw materials is each has something to recommend him, often kind of raw material has its weak point, so the film produced is difficult to the demand meeting various situation.Although also there are the way adopting different material used in combination in some companies, owing to lacking necessary testing installation and the testing program of test set and system, its effect is unsatisfactory.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
In order to overcome prior art Problems existing, the object of the present invention is to provide the food grade film of a kind of high barrier, high-air-tightness, high strength.
For achieving the above object, the invention provides a kind of food grade film, meter comprises following component by weight: the adjacent stupid dioctyl phthalate dioctyl ester 10 ~ 20 parts of high density polyethylene(HDPE) 70 ~ 80 parts, metallocene linear-low density polyethylene 5 ~ 10 parts, polyethylene resin 10 ~ 20 parts, epoxy tetrahydrochysene, at a high speed heat-sealing copolymerized type propene polymer 5 ~ 20 parts, multi-component copolymer polypropylene 1 ~ 10 part, titanium dioxide 0.1 ~ 1 part, filler 1 ~ 5 part.
Preferably, in technique scheme, described food grade film, meter comprises following component by weight: the adjacent stupid dioctyl phthalate dioctyl ester 17 parts of high density polyethylene(HDPE) 75 parts, metallocene linear-low density polyethylene 7 parts, polyethylene resin 15 parts, epoxy tetrahydrochysene, at a high speed heat-sealing copolymerized type propene polymer 13 parts, multi-component copolymer polypropylene 5 parts, titanium dioxide 0.5 part, filler 4 parts.
Preferably, in technique scheme, described filler is fabric fibre.
A preparation method for food grade film, comprises the following steps:
(1) raw material needed for production is taken on demand;
(2) raw material is mixed, adopt back the mode of heating up in a steamer, control temperature 150 ~ 200 DEG C, stir material with the speed that rotating speed is 80 ~ 100r/min, material is thoroughly dissolved, obtains mixed solution;
(3) mixed solution is left standstill 1 ~ 2 hour at 100 ~ 130 DEG C, pour the advection mould being preheated to 90 ~ 100 DEG C into, curtain coating, on the mirror steel plate of room temperature, makes the rapid gel of mixed solution chilling, and it is peeled off obtained high-temp liquid plastics film from steel plate.
Compared with prior art, the present invention has following beneficial effect: food grade film of the present invention, barrier and resistance to air loss good, there is good resistance to crocking, and intensity is high.Preparation method is simple, and easy handling, cost of investment is low, is beneficial to scale operation.
