Material packaging, quick-frozen food packaging, cooking food packaging, fast food packaging, these products are all brought greatly to people's life
Facility.
Plastics are closely bound up with daily life, and it is convenient, durable to have the advantages that, polybag is given birth to people really
It is living to bring conveniently, but this facilitates but bring permanent harm for the moment, the whole world year plastics discarded measure huge, waste plastic
Ratio in rubbish accounts for significant proportion, and this large amount of waste plastic is buried under the ground as rubbish, causes prodigious pollution,
White pollution caused by plastics is recognized by people.In recent years, degradation plastic has become research and development focus, degradable plastic
The exploitation of material realizes that sustainable development is of great significance for environmental protection.
According to American Society for Testing Materials by related plastics definition of the terminology standard to degradation plastic：It can
I.e. under certain environmental conditions, significant change occurs degradative plastics for chemical constitution, is used in combination the test method of standard that can measure
The plastics of its substance performance change, usual degradation plastic have following characteristics：Sunlight, oxygen, microorganism natural environment item
Under the influence of part, apparent variation occurs for the appearance of plastics；Apparent reduce occurs for mechanical property；Chemical constitution changes, and contains
It is medium that oxygen compound is introduced in plastics.Only when the above variation has occurred in plastic polymer, make the molecular weight of itself reduce and
It, could be by the microorganism decomposition in nature after generating small molecule oxygenatedchemicals.It is discarded that degradation plastic is expected to solution plastics
The pollution problem of object, therefore have become the hot spot of current research.
Utility model content
The purpose of this utility model is to provide a kind of degradable plastic films, mentioned above in the background art to solve
Problem.
To realize the utility model aim, the technical solution adopted is that：A kind of degradable plastic film, including degradable plastic
Expect film, starch plastic layer, agar layer, polycarbonate plastic, activation degrading microorganism layer, photodissociation oxidant layer and cellulosic plastics
Layer, the innermost layer of the degradable plastic film are set as cellulosic plastics layer, and the upper layer of the cellulosic plastics layer is provided with
The upper layer of agar layer, the agar layer is provided with photodissociation oxidant layer, and the upper layer of the photodissociation oxidant layer is set as polycarbonate plastic,
The polycarbonate plastic is internally provided with activation degrading microorganism layer, and the upper layer of the polycarbonate plastic is set as forming sediment
Powder plastic layer, the agar layer are clipped between polycarbonate plastic and starch plastic layer.
Preferably, the cellulosic plastics layer is specially the one or several kinds in stalk, straw, bagasse and megasse
Cellulose material is suppressed.
Preferably, the starch plastic layer is specially corn stubble, cracks rice and rice bran crushes, liquid agar layer it is viscous
Under cooperation is used, compacting, which is dried, to be made.
Preferably, it is described activation degrading microorganism layer be specially activated yeast and activation Escherichia coli in one kind or
Two kinds.
Preferably, the photodissociation oxidant layer is specially the one or several kinds in ferric stearate, manganese stearate and stearic acid sodium.
Preferably, the effective thickness of the degradable plastic film is 3~5mm.
Compared with prior art, the utility model has the beneficial effects that：
1. the utility model is by using the life effectively degraded under oxygen effect by photodissociation agent and activation degrading microorganism
Substance coordinates agar layer as outer layer, internal layer, under the action of photodissociation oxidant layer and activation degrading microorganism layer, realizes degradable plastic
Expect that the fast degradation Harmless of thin mould, green pollution-free embody superiority significantly, the requirement of user can be met.
