Well；It aluminizes setting on degradative membrane surface layer, degradation middle layer and the internal layer that hot sealing layer is constituted of degrading, is formed and plate aluminum base layer, the painting
Layer can effectively improve the barrier property of aluminium layer, and oxygen flow can reach 0.5cm3/m2/ following for 24 hours, moisture-inhibiting can reach 0.5g/m2/
It is following for 24 hours.
And under these conditions, plating aluminum base layer OD value is 1.7.So when the product is degraded in nature,
Outer layer can directly be irradiated by the UV light in sunlight and be decomposed, and internal layer is started point by the UV light that aluminium layer penetrates
Solution, the aluminium coated decomposition efficiency that specific optical density value is 1.9 promote 50%.
This coating and the mode for combination of aluminizing effectively obtain the decomposability solved after high obstructing performance and material, thus
The application is both easy degradation, achievees the purpose that environmental protection, and have outstanding barrier property, splendid shading performance, and heat-sealing
The packaging characters such as performance.
Further setting：It is equipped with adhesive layer between degradation treatment layer and plating aluminum base layer, for fixing internal layer and outer layer.
By using above-mentioned technical proposal, internal layer and outer layer can so be fixed, obtain better product packaging
Performance improves the barrier property of packaging bag, and can make it have splendid line easy-tear performance, is easy to use by users.
Further setting：Degradable membrane surface layer passes through oxidation-type biodegradation Biaxially oriented polypropylene with degradation treatment layer
Material is made as printing basement membrane printing.
Further setting：Degradation treatment layer, degradation middle layer and degradation hot sealing layer is three-layer co-extruded obtains biaxial tension and can drop
Solve polypropylene screen.
By using above-mentioned technical proposal, the degradability of internal layer and outer layer, while the plating aluminum base layer after degradation ensure that
It is not easy to further improve environmental effects the environmental-protecting performance of degradable bag.
In conclusion the utility model has the advantages that：
The decomposability solved after high obstructing performance and material effectively is obtained, thus the application is both easy degradation, reaches ring
The purpose of guarantor, and there are outstanding barrier property, the packaging characters such as splendid shading performance and heat sealability, and can make
It is easy to use by users with splendid line easy-tear performance.
