Description

The wet high ventilated membrane of preserving fruit and vegetable utilizing low-resistance and its production method
Technical field
The present invention relates to a kind of wet high ventilated membrane of preserving fruit and vegetable utilizing low-resistance and its production methods.
Background technique
One of China is fruits and vegetables big producer, and kind and yield occupy first place in the world, be the pillar industries of the national economy.But For a long time, pay attention to managing in antenatal, production in China's agricultural production, ignore the antistaling storing in postpartum, cause greatly economic damage It loses.It is needed in the case where more complicated more long with the requirement to food high quality, food with the improvement of people ' s living standards Ground keeps fresh, and keeps its flavor and nutriment.It is domestic generally to use polyethylene production preservative film, but polyethylene film makes With being also easy to produce out vinyl monomer in the process, and the fruits and vegetables that accelerate the ripening, the holding time is caused short to be easy to rot.But general film is due to saturating Gas is poor, and fruits and vegetables are also easy to produce the gases such as steam and carbon dioxide during preservation, and unfavorable day is fresh-keeping, therefore need to develop one kind Product can substitute polyethylene preservative film, and breathable permeable.
Summary of the invention
In view of the defect of the above-mentioned prior art, it is an object of the present invention to: a kind of wet height of preserving fruit and vegetable utilizing low-resistance is provided Ventilated membrane.
To solve the above problems, the technical solution of the invention is as follows: the wet high ventilated membrane of preserving fruit and vegetable utilizing low-resistance, it is by interior table Layer, intermediate core layer and extexine composition, in which:
Endosexine is made of copolymer polypropylene, antitack agent, antifoggant, inorganic silicon；
Intermediate core layer is made of homopolypropylene, antistatic agent, calcium carbonate；
Extexine is made of homopolypropylene, antitack agent.
Further, the component of endosexine is in mass ratio are as follows: copolymer polypropylene 90%, antitack agent 4%, antifoggant 6%.
Further, the component of intermediate core layer is in mass ratio are as follows: homopolypropylene 80%, antistatic agent 2%, calcium carbonate 8%, antifoggant 10%.
Further, appearance layer component is in mass ratio are as follows: homopolypropylene 95%, inorganic silicon 5%.
The present invention also provides a kind of production methods of above-mentioned wet high ventilated membrane of preserving fruit and vegetable utilizing low-resistance, comprising the following steps:
(1) endosexine, intermediate core layer, extexine original are weighed respectively in endosexine, intermediate core layer, extexine each component ratio Material, endosexine, intermediate core layer, extexine raw material individually carry out mixture, and the raw material after mixture is dried；
(2) endosexine after drying, intermediate core layer, extexine raw material are respectively fed to respective extruder and carry out melting mixing modeling Change；
(3) molten state melt is sent into three layers of die head respectively, melt passes through flat die head mouth after converging in die head Form molten state sheet material；
(4) sheet material is attached on sharp cooling roll with air knife and is formed for forming slab by sheet material after water-bath cooling；
(5) sheet material is drawn into film again respectively by vertical machine drawing and transverse drawing mill by slab；
(6) film is sent into winder using dragger and after carrying out thickness measuring, is rolled into big film roll；
(7) big film roll cuts into finished product again after Wetted constructures.
Further, the wet high ventilated membrane of preserving fruit and vegetable utilizing low-resistance with a thickness of 0.15mm.
The beneficial effects of the present invention are: film only has 0.15mm, softer, endosexine is had centainly using multiple copolymer Tack；After antifoggant is added, the steam that fruits and vegetables generate can be uniformly covered on film surface, not influence the shape of content State, it is high-visible；After middle layer joined calcium carbonate, certain hole can be generated during stretching, be convenient for internal gas Discharge outward.
Specific embodiment
For it is relatively intuitive, be fully understood by technical solution of the present invention, it is as follows now to carry out unrestricted feature description:
Embodiment one:
The wet high ventilated membrane of preserving fruit and vegetable utilizing low-resistance, it is made of endosexine, intermediate core layer and extexine, in which:
