Description

In-film labeling

The invention relates to a label, and in particular to an in-film label.

With the advancement of technology, the ways of food preservation and sales channels are also increasing. In the existing market, solid or liquid food is often filled in containers formed by plastic materials for easy transportation and sales.

However, the food filled in some plastic containers is easily affected by temperature, humidity and light, resulting in variation in food quality. In addition, although the existing filling technology is already quite accurate and reliable, errors are still inevitable when filling these liquid or solid foods, resulting in more food content in some containers and less food content in others, which in turn causes users to make selective purchases when purchasing, which is not conducive to the sale and preservation of food.

Therefore, how to effectively improve the freshness of plastic canned food, prevent food spoilage, and thus improve the appearance of packaging will help expand the quality and sales of canned food.

The novel content is intended to provide a simplified summary of the present disclosure so that readers can have a basic understanding of the present disclosure. This novel content is not a complete overview of the present disclosure, and its purpose is not to point out the important/key elements of the present invention or to define the scope of the present invention.

One of the purposes of the present invention is to provide an inner film label that can be safely and conveniently fixed on the outer shell of a plastic container, thereby improving the appearance of the plastic container, and can help to improve the freshness of food preservation and prevent food spoilage.

To achieve the above-mentioned purpose, one technical aspect of the present invention is an in-film label including a first protective layer, a pattern display layer, a metal layer and a second protective layer. The pattern display layer is formed on the surface of the first protective layer, the metal layer is attached to the surface of the pattern display layer, and the metal layer is formed on the surface of the second protective layer and attached to the surface of the pattern display layer. In addition, the first protective layer is formed of a light-transmitting material, so the pattern on the pattern display layer can be displayed through the first protective layer.

In some embodiments, the first protection layer includes a first surface treatment structure surface, which is a roughened surface formed by corona treatment.

In some embodiments, the second protection layer includes a second surface treatment structure surface, which is a roughened surface formed by corona treatment.

In some embodiments, the in-film label further includes a bonding layer formed on the surface of the pattern display layer to adhere to the metal layer.

In some embodiments, the metal layer is an aluminum metal film layer.

In some embodiments, the IFM label further includes an auxiliary bonding layer formed on the surface of the second protective layer to enhance the bonding strength with the metal layer.

In some embodiments, the auxiliary bonding layer is a bridging layer, and the metal layer is an electroplated aluminum metal layer formed by electroplating on the surface of the auxiliary bonding layer of the second protective layer.

In some embodiments, the first protective layer is a transparent protective layer formed of an oriented polypropylene (OPP) film.

In some embodiments, the second protective layer is a transparent protective layer formed by a directional stretched polypropylene film.

Therefore, the in-film label can highlight the color and pattern of the pattern layer of the in-film label, and improve the texture and durability of the in-film label. In addition, the in-film label can improve the heat preservation and cold preservation performance of the container, thereby increasing the shelf life of food, improving the shelf life of food, and improving the uniformity of the product, thereby stabilizing the shipping quality of the product.

FIG. 1 is a schematic three-dimensional view of a container having an IML, and FIG. 2 is a schematic side view of the IML.

First, referring to FIG. 1 , as shown in the figure, the plastic shell 110 of the container 100 is covered with a film inner label 120 to form a label with patterns or texts on the plastic shell 110 , thereby improving the aesthetics and practicality of the container 100 .

In some embodiments, the plastic shell 110 of the container 100 is formed by injection molding or blow molding with a film-attached label 120 to form a container with a label and a shell integrated, such as a bottle, cup or can for containing solid food or liquid beverages, which does not deviate from the spirit and protective device of the present invention.

Referring to FIG. 2 , as shown in the figure, the IML label 120 includes a first protective layer 210 , a pattern display layer 220 , a metal layer 260 and a second protective layer 240 .

The pattern display layer 220 is preferably formed on the surface of the first protective layer 210 by gravure printing to form a pattern and/or text on the inner surface of the first protective layer 210, and the first protective layer 210 is preferably formed of a light-transmitting material. Therefore, the pattern and text on the pattern display layer 220 can be displayed through the first protective layer 210, so that the user can observe from the outside of the container 100.

In addition, the metal layer 260 is formed on the surface of the second protective layer 240, and the second protective layer 240 and the metal layer 260 are attached to the pattern display layer 220 on the first protective layer 210, so that the pattern display layer 220 is located between the first protective layer 210 and the second protective layer 240, effectively improving the stability and wear resistance of the pattern display layer 220, thereby increasing the durability of the label.

In some embodiments, the inner surface of the first protective layer 210 includes a first surface treatment structure surface 212, such as a roughened surface formed by corona treatment. The inner surface of the second protective layer 240 may also include a second surface treatment structure surface 242, such as a roughened surface formed by corona treatment, but the present invention is not limited thereto.

In some embodiments, corona treatment is a process that uses electric shock to treat the surface of a plastic material to improve the adhesion of the surface of the plastic material. However, the present invention is not limited thereto. It may also adopt methods such as atmospheric plasma treatment, flame plasma treatment, and chemical plasma treatment to form a first surface treatment structure surface 212 and a second surface treatment structure surface 242, all of which are within the spirit and protection scope of the present invention.

In some embodiments, the IFM label 120 further includes a bonding layer 230 formed on a surface of the pattern display layer 220 to adhere to the metal layer 260 .

In some embodiments, the bonding layer 230 of the in-film label 120 may also be formed on the surface of the metal layer 260 to adhere to the pattern display layer 220 on the first protective layer 210, which does not deviate from the spirit and scope of protection of the present invention.

In some embodiments, the metal layer 260 is an aluminum metal film layer.

In some embodiments, the IFM label 120 further includes an auxiliary bonding layer 250 formed on the surface of the second protective layer 240 to enhance the bonding strength between the second protective layer 240 and the metal layer 260 .

In some embodiments, the auxiliary bonding layer 250 is a bridge layer, and the metal layer 260 is an electroplated aluminum metal layer formed on the surface of the auxiliary bonding layer 250 of the second protective layer 240 by an electroplating process. The second surface treatment structure 242 and the auxiliary bonding layer 250 can further improve the strength and stability of the metal layer 260 fixed to the surface of the second protective layer 240.

In some embodiments, since a metal layer 260, such as an electroplated aluminum metal layer, is formed on the inner side of the pattern display layer 220, the reflectivity of the pattern display layer 220 can be increased, the color and pattern of the pattern layer can be highlighted, and the texture and durability of the in-film label 120 can be further improved.

In addition, since the metal layer 260 is formed in the film label 120, the heat preservation performance and cold preservation performance of the container 100 can be improved, thereby increasing the shelf life of food, improving the shelf life of food stored in the container 100, and increasing the product value of the food container 100.

In some embodiments, the metal layer 260 is formed in the film label 120 to prevent external light from directly shining on the food, thereby further maintaining the freshness of the food. In addition, since light and temperature and humidity can be blocked by the metal layer 260, the shelf life of the food in the food container 100 can be increased.

It is noteworthy that when the user cannot see through the in-film label 120 having the metal layer 260, the user will not directly feel the slight difference in the amount of food stored in the container 100, which effectively reduces the user's screening of differences in food in different containers 100, helps to sell food on a first-in-first-out basis, and helps reduce the user's sense of difference in food in each container 100, thereby improving the uniformity of the product and stabilizing the delivery quality of the product.

In some embodiments, the first protective layer 210 and the second protective layer 240 are transparent protective layers formed by oriented polypropylene (OPP) films. However, the present invention is not limited thereto, and the first protective layer 210 and the second protective layer 240 can be formed by any plastic film material, which does not deviate from the spirit and protection scope of the present invention.

In view of this, the new IML label can highlight the color and pattern of the IML label pattern layer, improve the texture and durability of the IML label. In addition, the IML label can improve the heat preservation and cold preservation performance of the container, thereby increasing the shelf life of food, improving the shelf life of food, and improving the uniformity of the product, thereby stabilizing the product delivery quality.

However, the above is only the preferred embodiment of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. That is, all simple equivalent changes and modifications made according to the scope of the patent application and the description of the present invention are still within the scope of the patent of the present invention.
