害で残留溶剤の非常に少ない包装材料に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION By using a water-based ink and a water-based adhesive or a solvent-free adhesive, the present invention eliminates the use of organic solvents other than alcohol in the manufacturing process, and is non-polluting and extremely free of residual solvents. It is about less packaging material.
従来、包装材料の印刷に用いられるグラビアイ

臭気移行等包装材料の品質低下をもたらす場合が
あつた。更には、有機溶剤は可燃性であり、引火
の危険性が大きく、その取扱い、保管には十分な
注意が必要であつた。 Conventionally, gravure ink or flexo ink used for printing packaging materials has a composition of 60 to 70% by weight of organic solvents such as esters, alcohols, hydrocarbons, and ketones. By using this material, various binder resins can be used, expanding the scope of its application. However, these organic solvents scatter into the air after printing,
This has caused deterioration of the working environment and air pollution, and some of the solvent has remained in the printed matter as a residual solvent, resulting in deterioration in the quality of packaging materials such as the transfer of odor to the contents. Furthermore, organic solvents are flammable and pose a high risk of catching fire, and must be handled and stored with great care.

Although it varies depending on the type, ultraviolet or electron beam curable solvent-free adhesives are applied by methods such as gravure coating and roll coating, similar to conventional organic solvent adhesives. In addition, with moisture-curable solvent-free adhesives, the adhesive pan and coating roll are heated to raise the temperature of the adhesive to 80-120°C, thereby adjusting the viscosity of the adhesive to an appropriate level and reducing the coating amount by 1-2 degrees Celsius.
Apply so that it is g/m 2 . Furthermore, in the case of a two-component reactive solvent-free adhesive, two coating parts are provided, and the main ingredient and curing agent of the adhesive are applied to the base film and the bonded film, respectively.
