Description
Technical field
The invention belongs to PE technical field of membrane, and in particular to a kind of grease proofing PE preservative films.
Background technology
PE, complete entitled Polyethylene, is the simplest macromolecular organic compound of structure, the world today is most widely used
General high polymer material.PE diaphragms are divided into high density using Special polyethylene plastic sheeting as base material, according to the difference of density and gathered
Ethene diaphragm, medium density polyethylene diaphragm and low density polyethylene (LDPE) diaphragm.PE diaphragm biggest advantages are to be protected
Product producing and processing, transport, not contaminated, burn into scratches during storage and use, and protection is original bright and clean glossy
Surface, so as to improve the quality of product and the market competitiveness.
But there is following defect in traditional PE diaphragms：
(1), grease proofing poor permeability, traditional PE diaphragms are due to the linear state of its strand, when it is as food fresh keeping
When protecting fatty foods, oil molecule is easily arrived to film outer surface by the internal layer of film, middle level and outer layer, makes food for film use
Thing mutually pollutes；
(2), protected when PE diaphragms do product packaging film in use, when being particularly the packaging of some plastic products in PE
After film is taken apart, it can emit bad smell, have a strong impact on Consumer's Experience.
The content of the invention
Based on this, in view of the above-mentioned problems, the present invention proposes a kind of grease proofing PE preservative films, its by polypropylene to membrane modifying,
And make film that there is more preferable heat sealability by metallocene linear-low density polyethylene, make modified PE membrane moleculars chain into
Space multistory configuration, increase molecular density, can not when avoiding as fresh-keeping use so as to have the function that to prevent oil molecule from permeating
The situation for effectively separating grease and then triggering food mutually to pollute；Meanwhile aromatic substance laurene is added, make film that there is aroma
Taste, and laurene can coordinate with low density polyethylene (LDPE), LLDPE, heat seal strength that will not be to PE films and fracture
Tensile strength impacts.
The technical scheme is that：A kind of grease proofing PE preservative films, including be cascading internal layer, middle level and outer
Layer；The ratio between thickness of the internal layer, middle level and outer layer is followed successively by 1 ± 0.4：1±0.4：1±0.4：
It is 5 ± 0.4 that the raw material of the internal layer, which includes weight ratio,：2±0.3：1±0.2：1±0.2：1 ± 0.2 low-density
Polyethylene, high density polyethylene (HDPE), LLDPE, polypropylene and metallocene linear-low density polyethylene；
It is 10 ± 0.2 that the raw material in the middle level, which includes weight ratio,：10±0.2：10±0.2：2±0.1：2 ± 0.1 it is low close
Spend polyethylene, medium density polyethylene, high density polyethylene (HDPE), polypropylene and metallocene linear-low density polyethylene；
It is 5 ± 0.4 that the raw material of the outer layer, which includes weight ratio,：2±0.3：1 ± 0.2 low density polyethylene (LDPE), high density are gathered
Ethene and LLDPE；
The weight ratio of low density polyethylene (LDPE) in the internal layer, middle level and outer layer is 2:1:2.
There are polypropylene and metallocene linear-low density polyethylene in the internal layer of film and middle level, by polypropylene in film
Layer and middle level are modified, and film is had more preferable heat sealability by metallocene linear-low density polyethylene, are made modified
PE membrane moleculars chain increases molecular density, so as to have the function that to prevent oil molecule from permeating, avoids conduct into space multistory configuration
The situation that grease can not effectively be separated during fresh-keeping use and then trigger food mutually to pollute.

The main component of Water fixing agent in the present invention in middle level 20 is polyacrylamide, can quickly absorb water and slowly discharge,
When the film food more as water content such as preservative film protection veterinary antibiotics, the steam of food release can be quickly absorbed, is avoided
Condensation is formed in film, internal layer 10 is further absorbed after absorbing steam by middle level 20, increases water absorption, and the steam of internal layer 10 is first after water suction
Slowly release, the steam of middle level 20 slowly discharges again afterwards, makes to be in moist environment, the water that appropriate supplement loses in film all the time
Point, fresh-keeping effect is very good.
In another embodiment, the raw material of the outer layer 30 also includes Masterbatch, and the Masterbatch is low with outer layer 30
The mass percent of density polyethylene is 8%, or 10% or 12%.
Masterbatch is that film outer layer 30 is showed signs of anger as colouring agent, and Masterbatch and the low density polyethylene (LDPE) in outer layer 30, highly dense
Degree polyethylene and LLDPE have good intermiscibility, do not interfere with the heat seal strength and fracture tensile strength of film
Etc. performance.
In another embodiment, the raw material of the outer layer 30 also includes slipping agent, and the slipping agent is low with outer layer 30
The mass percent of density polyethylene is 0.8%, or 1.2% or 1.6%.
Embodiment described above only expresses the embodiment of the present invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.
