Description

A kind of antibacterial film for preventing from tumbling

Technical field

The technical field of material packaging is the utility model is related to, particularly a kind of antibacterial film for preventing from tumbling.

Background technology

Food security is always the much-talked-about topic of China's people's livelihood, and it is to ensure food peace to select suitable packing articles and material One of full important step, particularly have health, gas defence, the antibiotic packaging material of diseases prevention particularly important.China's packaging for foodstuff The shortcomings that level is still within the relatively backward stage at present, and antibacterial flexible packing material generally existing barrier is bad, easily makes Into food pollution, cause the food fresh keeping phase short, huge loss is brought to many enterprises the problem of because of product packaging.And itself band Have the antibiotic plastic packing articles of bacteriostasis, can not only reduce contact pathogenic bacteria, and not contaminating microorganisms environment, to ring Border safety.Therefore a kind of packaging film with durable antibiotic effect is developed, can not only improves the packaging product specification, good in China Good social benefit and ecological, environmental protective benefit, abundant economic benefit can also be brought to enterprise, is had broad application prospects.

A strip typically is made in packaging film in the prior art simultaneously, then is wound by wrap-up, completes winding Packaging film afterwards is cylinder, is easier to roll, and in rolling process weight, the packaging film of winding can be made to occur loose and make Failure must be wound, it is necessary to re-start winding, lose time, reduce operating efficiency.

Utility model content

The technical problems to be solved in the utility model is：Rolling occurs in order to solve the film of rolled to fall desk and make Into it is loose the problem of, the utility model provides a kind of antibacterial film for preventing from tumbling, and some grooves are circumferentially with inner ring, when After the film of rolled rolls, when groove contacts with desktop, the power for preventing to roll can be provided, so as to stop rolling It is dynamic, avoid because rolling and caused by film it is loose.

Technical scheme is used by the utility model solves its technical problem：A kind of antibacterial film for preventing from tumbling, bag Include：Outer ring and inner ring, the outer ring include：Antibiotic layer and basic unit, some projections are distributed with the basic unit, the antibiotic layer is answered Close above basic unit and and male cooperation, the inner ring there are some circumferentially distributed grooves, the basic unit is distributed in inner ring Circumference is simultaneously bonded with groove.

Specifically, the number of recesses is 4-8.

Specifically, the distance between described adjacent two groove is equal.

Specifically, the basic unit is PE films or PP films or polyurethane film.

Specifically, the thickness of the basic unit is 8-20 μm

Specifically, the antibiotic layer is nano-filled.

Specifically, the antibiotic layer thickness is 3-10 μm.

The beneficial effects of the utility model are：

The utility model provides a kind of antibacterial film for preventing from tumbling, and inner ring is circumferentially distributed to be had and some be used to prevent film Rolled after rolling up and cause loose groove, after film after rolling up rolls, when being rolled into groove Wait, due to not being that circular arc will stop, prevent from continuing rolling or even tumble desk and cause entire volume film loose.

The utility model provides a kind of antibacterial film for preventing from tumbling, and one layer of antibiotic layer is compounded with outside basic unit, can be made Film has antibacterial functions, and basic unit is additionally provided with projection, can increase the contact area of basic unit and antibiotic layer, bigger antibacterial aspect Product can have more preferable antibacterial effect.

Brief description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is a kind of structural representation for the antibacterial film for preventing from tumbling of the utility model；

Fig. 2 is the structural representation of outer ring；

In figure：1. outer ring, 11. antibiotic layers, 12. basic units, 13. is raised, 2. inner rings, 21. grooves.

Embodiment

The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram, Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.

As illustrated, the utility model provides a kind of antibacterial film for preventing from tumbling, including：Outer ring 1 and inner ring 2, outside Circle 1 includes：Antibiotic layer 11 and basic unit 12, some raised 13 are distributed with basic unit 12, antibiotic layer 11 is compounded in the top of basic unit 12 simultaneously Coordinate with projection 13, inner ring 2 has some circumferentially distributed grooves 21, basic unit 12 be distributed in the circumference of inner ring 2 and with groove 21 Fitting.

Specifically, the quantity of groove 21 is 4-8, and it is a kind of preferred forms to choose 6 grooves 21,6 grooves 21 Setting can be when ensureing the enough Datong District of the contact area of inner ring 2, and more grooves 21 can rotate smaller angle can be to prevent Only continue to roll, reduce the amplitude of rolling.

Specifically, the distance between adjacent two groove 21 is equal, and equally distributed groove 21 can cause what is rolled every time What amplitude was just as, meanwhile, such design is more attractive.

Specifically, basic unit 12 is PE films or PP films or polyurethane film.

Specifically, the thickness of basic unit 12 is 8-20 μm, and preferably 15 μm, basic unit 12 is used as freshness protection package, is ensureing tensile strength While, the setting of this thickness, freshness protection package is more frivolous, uses more convenient.

Specifically, antibiotic layer 11 is nano-filled, mainly by base-material polyvinyl resin (LLDPE), nano zine oxide (n- ZnO), nano-calcium carbonate (n-CaCO3) and titanate coupling agent composition, the mass percent of each raw material components are：Polyethylene tree Fat 30~45%, nano zine oxide 30~40%, nano-calcium carbonate 15~20%, titanate coupling agent 5~10%, select inorganic Nano zine oxide makees antiseptic, using its high-efficiency antimicrobial effect, high temperature resistant, it is non-discolouring the features such as, processing antibiotic plastic it is soft Packing articles.

Specifically, the thickness of antibiotic layer 11 is 3-10 μm, preferably 5 μm.

Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right Property scope.
