Composite sheet materials in which base paper such as tissue paper and aluminum foil are pasted with wax have been used as the packaging material for the inside of the gum board. These wrapping papers have been used for many years because they have high barrier properties and a beautiful appearance, and have properties suitable for use in packaging machines. However, in recent years, the price of aluminum foil has risen significantly due to various factors, making it extremely difficult to use it as wrapping paper primarily for economic reasons.Therefore, there is a demand for economical packaging materials that have the same characteristics as conventional packaging materials. The current situation is that this is increasing.

On the other hand, with the remarkable progress in vapor deposition technology, metal vapor deposited films have come into widespread use as packaging materials for various foods in place of the above-mentioned composite sheet materials, and attempts have been made to use them for packaging inside gum sheets. However, when metal-deposited paper is used as wrapping paper inside the board gum, since the base material of metal-deposited paper is paper, the surface condition is rougher than that of synthetic resin film.
As a result, it is not possible to form a smooth, glossy and beautiful metal vapor deposited film, and since it contains water, there are problems in removing water during the vapor deposition process and the adhesion of metal particles is weak.These problems have been solved. In order to do this, it was necessary to use a base paper coated with a filler on the surface, which caused problems such as increased cost. Furthermore, there is a latent problem in that it lacks adaptability to automatic packaging machines, which is the most important requirement for wrapping paper inside gum sheets. In other words, metallized paper lacks the so-called conformability (bending flexibility) necessary for packaging compared to the aluminum foil-laminated paper mentioned above, and the bending flexibility of the base paper during high-speed packaging is poor. There is a problem in that it is extremely difficult to carry out automatic packaging smoothly due to the remarkable stiffness. For these various reasons, metallized paper has not yet been applied to packaging inside gum boards, despite its expected economic advantages.

In this way, in the metal-deposited paper for packaging inside a gum board according to the present invention, the metal-deposited film 3 is transferred onto the surface of the base paper 1 via the adhesive 2, and the surface of the metal-deposited film imparts mold release properties to the synthetic resin. A releasing/protective layer is formed by adding a substance to the base paper 1, and the wax 4 is applied to the back surface of the base paper 1. Therefore, the metal vapor deposited film 3 has a smooth surface due to transfer formation. It is extremely beautiful, and its surface is protected with a protective layer, and wax 4 is applied to the back side of the base paper 1, so the resilience during folding is effectively reduced, and the paper The physical properties of metal-metalized paper, which was considered difficult to automatically wrap for gum internal packaging, have been improved, and the paper has the revolutionary effect of being applicable to high-speed automatic packaging machines.
