Its manufacturing process is: aluminium foil is the drying tunnel of 150 ℃ through temperature, carries out preheating, out carries out compoundly with the inner layer film of plastic film layers, and plastic film layers is tentatively compounded on aluminium foil.The fusing point of inner layer film is minimum, and aluminium foil is passed to the temperature of inner layer film after preheating, inner layer film can be tentatively compounded on aluminium foil; And then by pressure roller, plastic film layers and aluminium foil are compressed, make inner layer film and aluminium foil further compound, thereby form plastics film and aluminium foil composite bed; Plastics film and aluminium foil composite bed are the heated oven of 145 ℃ again through 4 meters of long temperature, Negotiation speed is 14m/min, the junction that the heat that drying tunnel provides arrives inner layer film and aluminium foil after outer membrane, mesopelagic layer, inner layer film, aluminium foil, further reinforces the combination between inner layer film and aluminium foil.For adapting to the above-mentioned approach that in drying tunnel, heat transmits, the fusing point of outer membrane, mesopelagic layer is higher than the fusing point of inner layer film.
In the present embodiment, in heated oven, the top of plastics film and aluminium foil composite bed is also provided with the blowing device towards katabatic wind, hot blast is blown to the rear resilience in heated oven bottom, thereby the heat of aluminium foil below is strong compared with baking oven top heat.The junction that arrives inner layer film and aluminium foil due to heat aluminium foil obviously penetrates outer membrane, mesopelagic layer, inner layer film and arrives the junction difficulty of inner layer film and aluminium foil than heat, therefore above-mentioned measure contributes to heat to be evenly passed to the junction of inner layer film and aluminium foil.
Drying tunnel out, after cooling, is shaped to the skin of toughness reinforcing aluminum foil and adhesive tape and the combination in middle level.After cooling, at the another side of aluminium foil, coat pressure sensitive adhesive and form primer layer, after oven dry, be shaped to toughness reinforcing aluminum foil and adhesive tape.
In the present embodiment, plastics film layer thickness is 40 μ m, and middle level aluminium foil layer thickness is 35 μ m, and primer layer thickness is 16 μ m.
