High-temperature cooking foil bags of aluminum foil surface cleanliness has a decisive influence on composite strength, if the aluminum foil surface cleanliness is poorer, residual oil, the composite strength is relatively poor.High temperature cooking foil bags in the process of aluminum foil rolling manufacture, use a lot of lubricating oil, rolling good aluminum foil before winding with organic solvent of acetone on its surface cleaning, clean rolling lubricating oil used in clean.In addition, flexible packaging used aluminum foil (soft aluminum) and under high vacuum (0.0133 Pa) state high temperature annealing treatment, make the aluminum foil surface residual oil evaporate into a gas.These are conducive to the improvement of its cleanliness, but it would still remain very little oil, and oil residue and determines the quality of the surface cleanliness, in which A grade cleanliness is best, almost no oil, B grades, general requirements to achieve B class above.
