In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a green biodegradable's plastic film, includes first base film, the outside surface bonding of first base film has the enhancement layer, the outside surface of enhancement layer is provided with the buffer layer, the buffer layer includes the second base film, the second base film bonds on the outside surface of enhancement layer, the outside of second base film is provided with a plurality of bubbles that distribute evenly, the surface bonding of bubble has first inoxidizing coating.

As a further aspect of the present invention, the outer surface of the first protective layer is provided with a printing layer.

As a still further aspect of the present invention, the second protective layer is further bonded to the outer surface of the first protective layer, and the printing layer is located inside the second protective layer.

As a further aspect of the present invention, the reinforcing layer is a net structure.

As a further proposal of the utility model, the circumferential sides of the first base film, the reinforcing layer and the buffer layer are coated with waterproof paint.

Compared with the prior art, the beneficial effects of the utility model are that:

1. this green biodegradable's plastic film has adopted first base film, the enhancement layer, mutually support between second base film and the bubble, the enhancement layer plays the effect of strengthening toughness to first base film, when fragile article of this film packing received external rigid collision, the bubble can play good cushioning effect, protect fragile article of packing, when having effectively solved some films and packing fragile article, do not possess the function of buffering, cause the cracked problem of inside fragile article easily when receiving external collision.

2. This green biodegradable's plastic film is provided with first inoxidizing coating, and when this film received external collision, external object was in contact with first inoxidizing coating back, and a plurality of bubbles can be given with the comparatively even dispersion of pressure that receives to first inoxidizing coating, can effectively reduce the ruptured condition of bubble, has further improved this film shock-absorbing capacity, and buffering effect is better.

3. This green biodegradable's plastic film is provided with the second inoxidizing coating, and the second inoxidizing coating can protect the printing layer, hinders the printing layer and fades, and the completion nature of printing layer still can be guaranteed to this film after long-term the use, is convenient for use for a long time.

Detailed Description

Example one

Referring to fig. 1-2, the green biodegradable plastic film of the present embodiment includes a first base film 1, and the first base film 1 may be a PBAT plastic film, which has good ductility and elongation at break, good heat resistance and impact resistance, and good biodegradability, and can be degraded by microorganisms in nature after use without environmental pollution. The outside surface bonding of first base film 1 has enhancement layer 2, and enhancement layer 2 is network structure, and enhancement layer 2 can adopt polypropylene to make, and polypropylene has good support hardness, and the enhancement layer 2 that sets up network structure can also improve tensile properties, can play the effect of strengthening toughness to first base film 1.

Wherein, the outside surface of enhancement layer 2 is provided with buffer layer 3, buffer layer 3 includes second base film 31, second base film 31 bonds on the outside surface of enhancement layer 2, the outside of second base film 31 is provided with the even bubble 32 of a plurality of distributions, second base film 31 and bubble 32 all can adopt PLA preparation to form, PLA also possesses good biodegradability, can be degraded completely by microorganism in the nature after the use, finally generate carbon dioxide and water, non-staining environment, when the fragile article of this film package received external rigid collision, bubble 32 can play good cushioning effect, protect the fragile article of packing, the fragile article that effectively hinders the packing breaks.
