Technical scheme: in order to solve the problems of the technologies described above, the shock-resistant compound container bag film of uvioresistant described in the utility model, it comprises PET theca externa, first adhesive layer, first connects rete, UV absorption rete, second connects rete, second adhesive layer, PET theca interna, aluminium coated and PE rete, they connect successively, described aluminium coated is plated in PET theca interna side, described PET theca externa, first adhesive layer, first connects rete, UV absorption rete, second connects rete, second adhesive layer, PET theca interna, the Thickness Ratio of aluminium coated and PE rete is 1:(4-6): (0.8-1.8): (0.8-1.8): (0.8-1.8): (4-6): (0.8-1.2): (7-8): (0.5-1.5).
Described first adhesive layer and the second adhesive layer are vinyl urethane adhesive layer.
Described PET theca externa, the first adhesive layer, first connect rete, UV absorption rete, second connect the thickness of rete, the second adhesive layer, PET theca interna, aluminium coated and PE rete be followed successively by 1-1.5 μm, 5-7 μm, 1-2 μm, 1-2 μm, 1-2 μm, 5-7 μm, 1-1.5 μm, 8-10 μm and 0.5-2 μm.
Described PET theca externa, the first adhesive layer, the first connection rete, UV absorption rete, the second thickness connecting rete, the second adhesive layer, PET theca interna, aluminium coated and PE rete are followed successively by 1.2 μm, 6 μm, 1.5 μm, 1.8 μm, 1.5 μm, 6 μm, 1.2 μm, 9 μm and 1 μm.
First connects rete, and be connected rete with second be PE film or high-low pressure co-extrusion PE film or nylon membrane or EVOH film.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model adopts multi-layer compound structure, by nine layers of compound, overall impact resistance is good, overall flexibility is good, adopt UV absorption rete, product is made to have uvioresistant function, and be connected by each layer, UV absorption rete uses stable, UVResistant effect is good, in PET theca interna side, aluminium coated is established in plating, the problem that before solving, aluminum membranous layer in use has folding line and fractures, ensure that the high sealing high barrier of product, improve whole service life, realistic instructions for use.
