Wide-adaptability packaging adhesive additive and application thereof

The invention discloses a wide-adaptability packaging adhesive additive and application thereof, and relates to the field of adhesives. According to the invention, a conventional mixture of dipropylene glycol dibenzoate, polysiloxane, polyether siloxane and 5-chloro-2-methyl-2H-isothiazol-3-one and 2-methyl-3(2H)-isothiazolinone is only adopted, so that the packaging adhesive taking the VAE emulsion as the matrix is suitable for packaging materials made of various materials, is particularly suitable for packaging of anti-counterfeiting laser aluminum-sprayed paper, laser holographic transfer paper, BOPP laser rainbow card paper, PET laser rainbow card paper, aluminum foil composite card paper and the like with aluminum foil, BOPP or PET layers on the surfaces, and is more suitable for packaging of soft package hardened folding surfaces with large elasticity, thin cigarette cases with small effective bonding area and the like. The invention solves the technical problems of limited bonding material, poor low te
