Composite bags transparency bad, how to return a responsibility?

Many packages require high transparency, using the blank base film to compound of large area, but sometimes present transparency undesirable phenomena, professional manufacturer of flexible packaging packaging thought this with adhesive, basal membrane element has a lot to do. 1, the adhesive itself too deep dark yellow color, yellow, red, sometimes even soy sauce soup that is dark red, on the film and the corresponding color. Therefore, under the requiring high transparency, should choose light yellow, even the colorless adhesive. 2, glue in the liquid mixed with dust and other particles in the workshop environment too much dust in the air, after the glue drying blow hot air in has in the tiny dust, glued on the rubber, composite center sandwiched between two pieces of the basement membrane, there are many small points, opaque. This is about to use adhesive solution 180 wire mesh filter, despite the insoluble particles of adhesive solution, also watch for workshop clean sanitation, let the light on the earth, arid dry, no dust, the dust in the air, less drying tunnel inlet can be used as high mesh filter or other filtering material to eradicate the hot air in the dust. 3, the surface tension of the basement membrane is not high adhesive solution for it cannot be evenly moist, to shorten, monotonous after a film is not uniform, bit by bit, owe good transparency, surface tension is greater than 38 mn/m in this film, or from the beginning, reoccupy after qualified. 4, adhesive of the lack of liquidity, flattening sex differences at this time to switch to liquid adhesive, or can use a bit of a flat solvent, but avoid too much residual solvents and the peculiar smell smell problem of the present. 5, the gluing quantity lack of space, with small air bubble, spotted or opaque, must check the amount of glue, make its satisfaction and uniform. 6, adhesive glue hygroscopic liquid itself, have become turbid, have not solute please match glue from scratch, and use of water, alcohol, acid, amine, such as reactive solvent. 7, the start into the bake, when temperature is too high too fast monotonous, make glue layer on the surface of the solvent active transpiration, forms part of the surface layer adhesive solution concentration, surface crust. Then after the internal heat to deepen to the adhesive solution layer, under the skin membrane solvent evaporation, break film, constitute a caldera that ring, round, also make the rubber is not uniform, opaque. Bake, since the entrance to the exit temperature, therefore, should be gradually, from low to high, let solvent orderly, continuously from internal to external transpiration. Other, can use different boiling point solvents, rubber surface when heated evaporation of high boiling point solvents to save a long time, without conjunctival surface crust. But to ensure that the same amount of residual solvents qualified, there is no bad smell peculiar smell. 8, compound rubber roller have shortcomings of one point pressure, gap, opaque. So often to see, if there are faults, even small, good also want to change.
