How to make aluminum foil paper?
A method to manufacture aluminum foil paper with forgery-proof watermark is made from paper pulp fiber. The production steps are as follows: Crash the pulp material with hydrapulper and beat with beater with beating degree of 20-70°SR and wet weight ≥0.5g; Add additives to the pulp: Filler 10-40％, sizing agent 1-8%, preservative 350ml/ton; Beating degree of 20-70°SR and wet weight ≥0.5g; Press the watermark net with die sinking, use watermark net at the vat of paper machine, reproduce the pulp into paper sheet with paper machine after being diluted, roll the sheet with calendar, slit the sheet into corresponding specification with slitter and then get the aluminum foil backing paper with forgery-proof watermark. The watermark of this invention is distributed uniformly, clearly visible as well as obviously rough and uneven in surface by touching, which has significant counterfeit effect, so it can be used to package the cigarette.
