Please refer to FIG. 1 , which is a method 100 for manufacturing an ink-repellent-contaminated packaging material, comprising: providing a substrate (step S10); preparing a high-binding ink (step S20); forming a high bond An ink layer (step S30); and a lamination layer is formed (step S40).

As shown in FIGS. 1 and 2, a substrate is provided (step S10), which is a substrate material prepared as a substrate for manufacturing an ink-repellent packaging material, and the substrate 10 used may be selected as a cardboard or a substrate. Polymer sheet.

The material of the substrate 10 can be selected as the paper substrate 10, that is, the container formed by the ink-repellent packaging material manufactured by the method for manufacturing the ink-repellent packaging material S100 can be a paper cup. A paper bowl or a paper box.

On the other hand, the material of the substrate 10 can also be selected as a polymer material, and the polymer material used can be selected from plastic or silicone materials which are relatively easy to obtain and cost-controlled.

As shown in Fig. 1, a high-binding ink is produced (step S20), which combines an ink with a bonder to form a high-junction ink. The ink layer used may be an aqueous ink, an oily ink, a solid ink, or a comprehensive ink. The binder used may be a maleic anhydride polyolefin containing from 1% to 20%.

As shown in FIGS. 1 and 3, a highly-bonded ink layer is formed (step S30) which forms a highly-bonded ink layer 20 on at least one surface of the substrate 10, and a highly-bonded ink layer. 20 may be formed on the entire surface or formed only on a portion of at least one surface of the substrate 10.

Next, referring to FIG. 1, FIG. 4A, and FIG. 4B, a coating layer is formed (step S40), which attaches a coating layer 30 to the substrate 10 or the highly-bonding ink layer 20.

On the other hand, in the embodiment shown in Fig. 4B, the surface of the substrate 10 on which the high-adhesive ink layer 20 is formed and the surface on which the high-adhesive ink layer 20 is not formed are covered, and the coating layer 30 is formed. This is the safest anti-ink material contaminated packaging material, and the ink or moisture is not blocked by the laminating layer 30 due to the barrier of the laminating layer 30.

Furthermore, as shown in FIGS. 5 to 8B, the manufacturing method S200 is a method for manufacturing an ink-repellent-contained packaging material, and further includes a step of forming a container (step S50) to prevent the ink from contaminating the packaging material. An ink repellent contamination container 100, an ink repellent contamination container 200 or an ink repellent contamination container 300, wherein the ink repellent contamination container 100, the ink repellent contamination container 200 or the ink repellent contamination container 300 may be a cup body or a bowl. Body or box.

As an example of the ink repellent container 100 shown in FIGS. 6A and 6B, only the outer surface of the substrate 10 is formed with a highly-bonding ink layer 20. As an embodiment of the ink repellent container 200 shown in FIGS. 7A and 7B, the outer surface and the inner surface of the substrate 10 are each formed with a highly-bonding ink layer 20. The embodiment of the ink repellent container 300 as shown in FIGS. 8A and 8B is the outer surface, the inner surface and the inner bottom surface of the substrate 10. A highly integrative ink layer 20 is formed.

As shown in FIGS. 6A to 8B, the ink repellent container 100, the ink repellent contamination container 200, or the ink repellent contamination container, whether directly on the surface of the substrate 10 or above the high-binding ink layer 20. The outermost layer of the interior or exterior of 300 is the laminar layer 30.

In summary, the ink-repellent-contaminated container 100 having the coating layer 30, the ink-repellent-contaminated container 200, or the ink-repellent-contaminated container 300 all use a highly-bonded ink layer 20 mixed with a binder. The coating layer 30 can be adhered to the high-binding ink layer 20, and the coating layer 30 can be attached to the substrate 10 and the high-binding ink layer 20 at the same time, and the coating layer 30 is effectively isolated. The ink in the highly-bonded ink layer 20 achieves the effect of preventing ink contamination, and ensures the use of hygiene and the possibility of avoiding contact with toxic substances in the ink.
