Description

Insulation sheet paper for cold and warm product transport box and its manufacturing method {INSULATING SHEET PAPER FOR FROZEN PRODUCTION TRANSPORTATION BOX AND MANUFACTURING METHOD THE SAME}

The present invention relates to a transport box thermal insulation sheet paper for cold and thermal insulation products and a method for manufacturing the same, and more particularly, to form a corrugated form by laminating a metal foil made of aluminum and a bonding paper, and the inner paper and the other side on one side of the insulating paper By providing a printing paper with a printing surface on it, it replaces the styrofoam box and performs the function of cooling and thermal insulation, and the printing surface is integrally formed on the printing paper, thereby improving the printing quality. It relates to a manufacturing method.

In general, ice cream, beverages, frozen and refrigerated meat, chicken, pizza, and hot foods such as cold storage (frozen products, refrigerated products) and warm product transport boxes block cold air and heat from leaking to the outside. And as a box to be stored and transported in a warm state, it is also referred to as a cool and warm box.

The cold and warm product transport box mainly includes a box body formed to have an accommodation space therein using styrofoam, and a cover made of scrofoam material that covers the box body. A vinyl sheet paper is attached to the circumference of the box body, and the vinyl sheet paper is configured to have a printing surface consisting of the product name, manufacturing date, and various information.

Transport boxes for these cold and warm products were mainly manufactured with styrofoam.

However, in the related art, in the case of manufacturing and using styrofoam transport boxes for cold and warming products, there are several problems such as reluctance to collect styrofoam from collection companies because recycling of styrofoam gradually becomes difficult due to the strengthening of environmental laws. In addition, since it is impossible to print directly on the circumferential surface of the styrofoam in the conventional cold and warm product transport box, vinyl paper having a printing surface is adhered with an adhesive. This is a crying phenomenon in the area where the adhesive is not adhered. Since it does not provide a sense of unity, it has a problem that print quality is remarkably deteriorated.

Therefore, there is a need to improve this.

1 to 4, the insulation sheet paper 100 for a cold and warm product transport box according to an embodiment of the present invention includes a heat insulation laminate 10, an inner paper 20 and a printing paper 30 It is done by doing.

Insulation sheet paper 100 for a cold and warm product transport box according to an embodiment of the present invention is manufactured and then subjected to a process such as cutting, folding, bonding, etc. to be used as a cold and warm product transport box. The inner part of the inner paper 20 is used as a storage place for cold and warm products, and the printing surface 32 of the printing paper 30 is used as logo, trademark and notification information of the cold and warm products.

The heat insulating paper 10 is formed by combining the metal foil 12 and the bonding paper 14, and is formed to improve heat insulation.

The metal foil 12 is characterized in that it includes any one of aluminum foil or copper foil.

In one embodiment of the present invention, the metal foil 12 is illustrated and described as using aluminum foil.

As the metal foil 12 is formed by thinly spreading aluminum, etc., the bonding paper 14, printing paper 20, and inner paper 30 are formed of pulp having a cellulose fiber structure to cool and warm (heat). While the movement is free to reduce cold and warmth, the metal foil 12 has a feature of improving the cool and warm function since the airtightness is improved by blocking the movement of cold and warm air (hot).

The bonding paper 14 may be made of ordinary paper, and in some cases, the bonding paper 14 may be made of a cardboard having a thick thickness. Thereby, the material of the bonding paper 14 is not limited,

The thermal insulation paper 10 may be arranged by bending the thermal insulation paper 10 in a corrugated shape so that a heat shielding space is formed while the protrusions are adhered to the sides of the printing paper 20 and the inner paper 30. By being formed, as the concave heat shielding space is repeatedly formed, it is possible to improve the cool and warm function by reducing the loss of cold and warm air of the cool and warm products stored inside the inner paper 30.

The protruding part of the corrugated insulating paper 10 is adhered to one side of the inner paper 20 and one side of the printing paper 30 in a state that minimizes the contact area through an adhesive, thereby minimizing the transfer area of cold and warm air. have.

The inner paper 20 is formed by bonding to the bonding paper 14 of the heat insulating paper 10, and is configured to form the inner surface of the transport box.

The inner paper 20 may be made of ordinary paper, and in some cases, the inner paper 20 may be formed of a cardboard having a thick thickness. Thereby, the material of the inner paper 20 is not limited,

A protective layer may be further provided on the inner side of the inner paper 20 to prevent absorption of moisture and foreign matter. The protective layer may be formed as a coating or may be formed by applying a synthetic resin coating.

The printing paper 30 is formed by bonding to the metal foil 12 of the heat insulating paper 10, and has a printing surface 22 on the outer surface thereof.

The printing surface 32 is formed integrally by printing on the outer surface of the printing paper 30 through a printer.

Thus, in the prior art, there is a problem in that the printed vinyl paper is peeled off or separated as the printed vinyl paper is adhered to the circumferential surface of the styrofoam box, whereas in the case of the present invention, the printing surface ( As 32) is formed integrally, there is no fear of separation of the printing paper 30 and the printing surface 32 as well. Print quality can be improved.

Referring to FIG. 3, a coating layer 40 may be formed on the outer surface of the printing paper 30.

Since the metal foil 12 and the coating layer 40 block air movement between the metal foil 12 and the coating layer 40, the cold and warm products stored inside the inner paper 20 reduce the loss of cold air and heat. And it characterized in that it improves the warming function.

The coating layer 40 may include a laminate coating layer.

As the coating layer 40 is laminated to a set thickness on the printing surface 32 of the printing paper 30, the bonding paper 14, the inner paper 20, and the printing paper 30 have a cellulose fiber structure. As it is formed of pulp (paper), cold and warm air can be moved freely and the cold and warm performance may be deteriorated, but the coating layer 40 doubles the movement of cold air and warm air along with the metal foil 12 to improve airtightness. Therefore, the cooling and warming performance can be improved.

Referring to FIG. 4, a reinforcing metal foil 50 may be further included on one side of the inner paper 20.

Since the metal foil 12 and the reinforced metal foil 50 block air movement between the metal foil 12 and the reinforced metal foil 50, the cold air and heat of the cold and warm products stored inside the reinforced metal foil 50 Reduce the heat loss and improve the cool and warm function.

The reinforcing metal foil 50 may include any one of aluminum foil or copper foil.

In an embodiment of the present invention, the reinforcing metal foil 50 is illustrated and described as being formed of aluminum foil.

As the reinforced metal foil 50 is formed by thinly spreading aluminum, etc., the bonding paper 14, the inner paper 20, and the printing paper 30 are formed of pulp (paper) having a cellulose fiber structure, so that it is cold and warm. It is free to move and may deteriorate the cold and warm performance, but the reinforced metal foil 50 doubles the movement of cold and warm air (hot air) together with the metal foil 12 to improve airtightness. Can be promoted.

In particular, a spaced space is formed between the auxiliary metal foil 50 and the metal foil 12 by the corrugation shape of the thermal insulation paper 10, and as air does not move in the spaced space, cold air and warmth (heat ) By significantly lowering the delivery state, the cooling and warming performance can be further improved.

On the other hand, the configuration of forming the coating layer 40 on the outer surface of the printing paper 30 in FIG. 3 and the configuration of forming the reinforcing metal foil 50 on the inner surface of the inner container 20 in FIG. May be.
