The invention discloses a blister packaging film for gamma ray disinfection. The blister packaging film comprises seven layers, wherein the layer A is made from polyamide 6, the layer B is made from bonding resin, the layer C is made from 60-80% linear low-density polyethylene and 20-40% low-density polyethylene, the layer D is made from bonding resin, the layer E is made from polyamide resin, the layer F is made from bonding resin, and the layer G is made from 60-80% linear low-density polyethylene and 20-40% metallocene polyethylene; the thickness of the layer A accounts for 5-10% of the total thickness of the blister packaging film, the thickness of the layer B accounts for 5-10% of the total thickness of the blister packaging film, the thickness of the layer C accounts for 20-30% of the total thickness of the blister packaging film, the thickness of the layer D accounts for 5-10% of the total thickness of the blister packaging film, the thickness of the layer E accounts for 5-10% of the total thickness of the blister packaging film, the thickness of the layer F accounts for 5-10% of the total thickness of the blister packaging film, and the thickness of the layer G accounts for the rest of the total thickness of the blister packaging film. The blister packaging film is obtained through extrusion, film blowing, air cooling, water-cooling setting, surface treatment and coiling, integration of different layers is good, biphase separation does not occur during blister forming, the mechanical strength of products is high, polyethylene (PE) and medical dialyzing paper heat sealing effect is good, sealing starting temperature is low, heat sealing strength is high, and the blister packaging film is especially suitable for gamma ray disinfection.
