5, a soft soft layer 110, a foil layer 120, a base coating layer 130, and a soft magnetic layer 130 are formed on the soft soft layer surface forming structure by enhancing the cohesive force of the surface particles according to the present invention. And a surface tension layer (140).

First, in the case of the soft soft layer 110, it corresponds to a soft soft layer, which is a material that can selectively or simultaneously contain PE or PP.

In the case of the soft soft layer 110, it is injected in the form of a thin layer. After the injection, the soft soft layer 110 is introduced into a predetermined process by a roller or the like.

In the case of the soft soft layer 110, one end and the other end of the soft softening layer 110 are dried to face each other, and one end and the other end are bonded to each other to form a cylindrical inner space.

In the case of the soft soft layer 110, when the conventional resin layer 11 is cylindrically dried as shown in FIG. 2 (b) and then is flatly pressed, as in the area A of FIG. 2 (b) As shown in FIG. 3, a cracking phenomenon occurs, and this cracking phenomenon damages the printed layer printed on the resin layer 11, thereby deteriorating the quality of the product Resulting in shortened life span.

In addition, as shown in Fig. 4, the pulling by the rollers 2a, 2b, 3a, and 3b causes stains due to pulling as shown in Fig. 4 (b) The printing quality would be greatly degraded.

The degree of selective absorption or reflection of the wavelength of the visible light can be arbitrarily set on a granule basis and can be confirmed by the user's eyes.

As shown in FIG. 6, the shape of the fine particles forms a rule according to the following equation (1) on the soft soft layer 110.

(1)? Sf =? Sl + gamma lf * cos?

(I) γsl is the interfacial tension between the liquid type fine particle and the surface on which the fine particle is placed, (ii) γlf is the fine (Iii) γsf is the adsorption equilibrium of the fine particles and the surface tension of the surface on which the fine particles are deposited, and (iv) θ corresponds to the wetting angle.

In the state shown in Fig. 6, the wetting angle? In the formula (1) is lowered, so that the uniformity of the applied thickness of the fine particles can be improved, and the application of the ideal particles is made close to.

As shown in FIG. 7, when the soft soft layer 110 is bent to a greater angle than the critical angle, it is possible to provide a tensile force of the surface forming the critical angle to form a soft soft layer 110 are prevented from being damaged.

More specifically, when a predetermined tensile force is generated in the soft soft layer 110, the surface tension layer 140 reduces the sagging of the surface of the soft soft layer 110. Such a mechanism is described in detail in FIG. 9 .

The force f2 acting between the distances d2 between the tension particles 140a is stronger than the force f1 acting between the soft particles 110a and the distances d1 between the soft particles 110a.

10, in the case of the surface tension layer 140, the weakness of the surface tension of the soft softening layer 110 such as a toothpaste tube is compensated for, and the fine particles are seated on the surface tension surface thus complemented .

As shown in FIG. 10, in the case of such fine particles, it is possible to selectively absorb or reflect the wavelength band of various visible light rays as desired, and these fine particles are applied in a molten state on the surface tension layer 140 And hardened and fastened within a short time. As shown in FIG. 10, optionally, any optional lamination of the cured fine particles is then possible, which may result in the formation of various optional layers depending upon the various laminations of fine particles.

11, a surface tension layer 140 and a protection layer (not shown) covering the fine particle layer 150 are formed on the fine particle layer 150 having various arbitrary layers on the surface tension layer 140 160 may be provided.

The protection layer 160 may be made of a synthetic resin such as PE, PET, or PP. It is important that the protection layer 160 has a transparent property for selective absorption and reflection of visible light, which is a functional property of the fine particle layer 150.

The protection layer 160 prevents any deviation of the fine particles and prevents the fine particles from being impacted or friction caused by external impact, or from being jammed or interfered with by twisting or rubbing.
