Specific embodiment

It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase Mutually combination.The utility model will be described in detail below with reference to the accompanying drawings and embodiments.

As shown in Figure 1,1 degradable membrane of the utility model embodiment from top to bottom successively includes the first peelable barrier layer 11, the peelable barrier layer 14 of the first degradable substrate layer 12, composite layer 13, second, the second degradable substrate layer 15, installation Glue-line 16, release layer 17, the barrier layer 11,14 are used to obstruct the degradation factor of degradable substrate layer；Described first is degradable Substrate layer and/or the second degradable substrate layer surface are the netted knot in the hole for being 0.1~25 μm at least two apertures Structure.

Degradable substrate layer had not only had the function of conventional plastic and characteristic but also can pass through soil after reaching service life Microbial action in earth and water or the effect by the ultraviolet light in sunlight, division degradation in the natural environment, finally with also Original shape formula reenters in ecological environment, goes back to nature.

In the utility model, Light lysis Film, light-ecological film film, photooxidation Biodegradable films, high-content of starch type can be selected Biodegradable films, high carbon acid calcium filled-type photooxidation droping film or complete biodegradable film etc..Wherein there are commonly water-soluble films such as Polyethylene oxide thin film BOPP, product can keep the build-in attribute of BOPP film；And with low density polyethylene (LDPE) (LDPE), linear Or mixtures thereof low density polyethylene (LDPE) (LLDPE), high density polyethylene (HDPE) (HDPE) are raw material, add appropriate degradation agent, manufactured The degrading polyethylene film of light degradation, biodegrade and environment degradable.

To avoid in normal use process, above-mentioned degradation factor such as light, photo-biological, photooxidation biology etc. and degradable base The contact of material layer, causes degradable substrate layer to be degraded in advance, has used barrier layer in the utility model fenestrated membrane.For stopping corresponding drop Solve the factor.If substrate layer such as selects Light lysis Film, then barrier layer is light barrier layer；If substrate layer is Biodegradable films, then obstruct Layer is oxide skin(coating) with microbial barrier.
