Abstract
The utility model discloses a kind of modified antimicrobial preservative films, including preservative film base, preservative film base top is provided with top chitosan antibiotic layer, it is provided with metal ion antibiotic layer between the top chitosan antibiotic layer and preservative film base, preservative film base lower part is provided with lower part chitosan antibiotic layer, it is provided with antibacterial zeolite particles film layer between the lower part chitosan antibiotic layer and preservative film base, base's micropore through preservative film groundwork thickness direction is evenly distributed in the preservative film base, Nanometer Copper is distributed in preservative film base inner homogeneous, zinc polymer particles.This kind of modified antimicrobial preservative film have the advantages that antibiotic property is good, not available for the existing products such as safe and non-toxic.
Description
Technical field
The utility model is related to a kind of antistaling film, especially a kind of modified antimicrobial preservative film.
Background technology
In daily life, preservative film is a kind of common fresh-keeping article.
Since preservative film is in direct contact various food, and with after preservative film packaged food, preservative film is straight with food
It connects there is also the air gap, this portion gap can grow a large amount of bacteriums, influence food security.Therefore, the safety of preservative film and anti-
Bacterium function becomes a very important index of preservative film.
The preservative film of early stage does not have an antibacterial functions, and the antimicrobial form preservative film generally existing anti-microbial property in later stage it is insufficient,
Preservative film material not enough safely, be easy to cause the defects of secondary pollution, seriously threaten daily food security.
The many disadvantages seriously limit preservative film field and develop and promote and apply further along.
It is lacked in view of this, the purpose of this utility model is to provide a kind of new technical solutions with solving existing technology
It falls into.
Utility model content
For overcome the deficiencies in the prior art, the utility model provides a kind of modified antimicrobial preservative film, solves existing
Preservative film anti-microbial property is poor, there are the technological deficiencies such as security risk.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of modified antimicrobial preservative film, including preservative film base, it is poly- that preservative film base top is provided with upper case
Sugared antibiotic layer is provided with metal ion antibiotic layer, the preservative film between the top chitosan antibiotic layer and preservative film base
Base lower part is provided with lower part chitosan antibiotic layer, and antibacterial is provided between the lower part chitosan antibiotic layer and preservative film base
Zeolite membrane layer is evenly distributed with base's micropore through preservative film groundwork thickness direction, preservative film in the preservative film base
Nanometer Copper, zinc polymer particles are distributed in base's inner homogeneous.
As an improvement of the above technical solution, the preservative film base is polyvinylidene chloride film layer.
As a further improvement of the above technical scheme, the metal ion antibiotic layer is silver-ion antibiotic layer.
The utility model has the beneficial effects that：The utility model provides a kind of modified antimicrobial preservative film, this kind improves
Type antimicrobial preservative film is provided with top chitosan antibiotic layer, lower part chitosan antibiotic layer, metal ion antibiotic layer and antibacterial zeolite particles
Film layer can effectively promote the antibacterial ability of this kind of preservative film, safe and non-toxic, safe；In addition, the preservative film base
Nanometer Copper, zinc polymer particles are distributed in inner homogeneous, can further promote the anti-microbial property of preservative film.
In short, this kind of modified antimicrobial preservative film solves, existing preservative film anti-microbial property is poor, there are the skills such as security risk
Art defect.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The technique effect of the design of the utility model, concrete structure and generation is carried out below with reference to embodiment and attached drawing

It encloses.In addition, all connection/connection relations arrived involved in patent, not singly refer to component and directly connect, and referring to can be according to specific
Performance, by adding or reducing couple auxiliary, to form more preferably coupling structure.Each skill in the utility model creation
Art feature, can be with combination of interactions, referring to Fig.1 under the premise of not conflicting conflict.
A kind of modified antimicrobial preservative film, including preservative film base 3,3 top of preservative film base are provided with upper case
Glycan antibiotic layer 1 is provided with metal ion antibiotic layer 2 between the top chitosan antibiotic layer 1 and preservative film base 3, described
3 lower part of preservative film base is provided with lower part chitosan antibiotic layer 5, between the lower part chitosan antibiotic layer 5 and preservative film base 3
It is provided with antibacterial zeolite particles film layer 4, the base through 3 thickness direction of preservative film base is evenly distributed in the preservative film base 3
Nanometer Copper, zinc polymer particles are distributed in layer micropore, 3 inner homogeneous of preservative film base.
Preferably, the preservative film base 3 is polyvinylidene chloride film layer.
Preferably, the metal ion antibiotic layer 2 is silver-ion antibiotic layer.
When the utility model is embodied, this kind of modified antimicrobial preservative film be provided with top chitosan antibiotic layer 1, under
Portion's chitosan anti-bacteria layer 5, metal ion antibiotic layer 2 and antibacterial zeolite particles film layer 4 can effectively promote the antibacterial of this kind of preservative film
Ability, it is safe and non-toxic, it is safe；In addition, Nanometer Copper, zinc polymer particles, energy is distributed in 3 inner homogeneous of preservative film base
Enough anti-microbial properties for further promoting preservative film
It is to be illustrated to the preferable implementation of the utility model, but the utility model creation is not limited to institute above
Embodiment is stated, those skilled in the art can also make various be equal without departing from the spirit of the present invention
Deformation is replaced, these equivalent deformations or replacement are all contained in the application claim limited range.
