Abstract
The utility model relates to a plastic film for antibacterial food packaging. The plastic film is of a layered structure and is divided into three layers, namely an inner antibacterial layer, an outer antibacterial layer and a middle layer attached between the inner antibacterial layer and the outer antibacterial layer. The plastic film has good antibacterial and bacteriostasis functions, biodegradability, mechanical property, high and low temperature resistance and oxygen isolation performance, and the layered structure is clear and simple. Polypropylene serves as matrix resin of the inner antibacterial layer and the outer antibacterial layer so that the plastic film has good material mechanical property and high and low temperature resistance. In addition, the plastic film has good biodegradability due to degradable plastic master batches.
Description
Technical field
The utility model belongs to field of plastic products, relates to the packing plastics film, especially a kind of antibacterial food plastic film for wrapping.
Background technology
The food antimicrobial packaging is the field, Chaoyang in the food active packing, and it is the most useful wherein selecting the antibacterial film packing, and it can suppress microbial growth, guarantees the safety of food, prolongs the shelf life of food.At present, the used for packing foods plastic sheeting is various in style, mainly contains catalytic type inorganic antibacterial agent film, natural and high-molecular anti-bacteria agent film, compoundization antiseptic film, inorganic antiseptic is thin and organic anti-bacterial agent film etc.From preparation food antimicrobial packaging film process, mainly contain two big classes.One class is that antiseptic is made antibacterial matrices, by antiseptic or antibacterial matrices with the resin individual layer is extruded or hydrostomia preparation get, and also can be by extruding the formation antimicrobial compound film jointly as superficial layer and other layer; Another kind of is by antiseptic coating or evaporation are got on resin film.
Biodegradable plastic is one of effective way of administering plastic refuse environmental pollution and buffering oil resources contradiction.Therefore, the biodegradability of food product packing film is one of present its Essential Performance Requirements.At present, it is a lot of to have antibiotic and plastic membrane product bacteria resistance function, and the plastic membrane product with biodegradable is also a lot, but can satisfy the packaging for foodstuff requirement simultaneously and have antibiotic property and the plastic sheeting of biodegradability comparatively rare.As seen, the food antimicrobial packaging film that obtains to have biodegradability is development main flow and the difficult problem of present used for packing foods plastic sheeting.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of and have good mechanical performance, resistant of high or low temperature, oxygen barrier, and antibacterial food plastic film for wrapping simple in structure.
The purpose of this utility model is achieved through the following technical solutions:
A kind of antibacterial food plastic film for wrapping, this plastic sheeting be laminar texture and be divided into three layers, be respectively interior antibiotic layer, outer antibiotic layer and be attached in interlayer between antibiotic layer and the outer antibiotic layer.
And described interior antibiotic layer and outer antibiotic layer all are to be made by the blend composition of polypropylene, degradation plastic masterbatch and CNT, and interior antibiotic layer and outer antibiotic layer thickness are 15 ~ 20 μ m.
And described interlayer is made by the degradation plastic masterbatch.
Advantage of the present utility model and good effect are:
1, antibacterial food plastic film for wrapping provided by the utility model has good antibiotic and bacteria resistance function, biodegradable, and have good mechanical performance, resistant of high or low temperature, an oxygen barrier, hierarchy is clear and simple, interior antibiotic layer all is matrix resin with the polypropylene with outer antibiotic layer, so thin film material mechanics performance, high and low temperature resistance are good, and the degradation plastic masterbatch makes film have the favorable biological degradability energy.
2, the whole cladding material of film has excellent and long-acting pressing down to kill effect to all kinds of Gram-negative bacterias, gram-positive bacteria, fungi onset to hundreds of mushroom that comprises Escherichia coli, staphylococcus aureus, Candida albicans, Friedlander, Pseudomonas aeruginosa etc. in the utility model.
Description of drawings
Fig. 1 is this antibacterial food plastic film for wrapping laminar texture enlarged diagram.
The specific embodiment
Below in conjunction with accompanying drawing this is further specified the utility model, following embodiment is illustrative, is not determinate, can not limit protection domain of the present utility model with following embodiment.
A kind of antibacterial food plastic film for wrapping, this plastic sheeting be laminar texture and be divided into three layers, in being respectively antibiotic layer 1, outer antibiotic layer 3 and be attached in interlayer 2 between antibiotic layer and the outer antibiotic layer.
Interior antibiotic layer and outer antibiotic layer all are to be made by the blend composition of polypropylene, degradation plastic masterbatch and CNT, and interior antibiotic layer and outer antibiotic layer thickness are 15 ~ 20 μ m, and interlayer is made by the degradation plastic masterbatch.Polypropylene can guarantee the mechanical properties in films requirement, the degradation plastic masterbatch makes film have the favorable biological degradability energy, CNT has good antibiotic and fungistatic effect, the whole cladding material of film is to all kinds of Gram-negative bacterias, gram-positive bacteria, fungi onset, have excellent pressing down to kill effect to hundreds of mushroom that comprises Escherichia coli, staphylococcus aureus, Candida albicans, Friedlander, Pseudomonas aeruginosa etc., and antibacterial effect have long-lasting.
Claims (2)
1. antibacterial food plastic film for wrapping is characterized in that: this plastic sheeting is laminar texture and is divided into three layers, be respectively interior antibiotic layer, outer antibiotic layer and be attached in interlayer between antibiotic layer and the outer antibiotic layer.
2. antibacterial food plastic film for wrapping according to claim 1, it is characterized in that: described interlayer is made by the degradation plastic masterbatch.
