An oil-proof adhesive label

Abstract

This utility model discloses an oil-resistant self-adhesive label, belonging to the technical field of self-adhesive label technology. It includes a self-adhesive label body with an oil-resistant layer on its surface, comprising a PE film layer and a PP film layer. An adhesive layer is provided on the back of the self-adhesive label body, with locking rings around the adhesive layer on the back. Release paper is provided at the bottom of the adhesive layer, and the release paper has a tear-off area. This utility model utilizes water- and oil-repellent masterbatches added to the PE and PP film layers during manufacturing. These masterbatches contain fluorinated compounds, which form a special microstructure on the surface of the self-adhesive label body, thereby reducing the surface energy of the self-adhesive label body. This makes it difficult for liquids such as water and oil to spread and adhere to the surface of the self-adhesive label body, thus giving the self-adhesive label body oil-resistant functionality.

Description

Technical Field

[0001] This utility model belongs to the field of self-adhesive label technology, specifically relating to an oil-resistant self-adhesive label. Background Technology

[0002] Self-adhesive labels have advantages over traditional labels, such as no need for glue, paste, or water, no pollution, and saving labeling time. They have a wide range of applications and are convenient and quick. Self-adhesive labels are a type of material, also called self-adhesive label material. They are composite materials with paper, film or other special materials as the face stock, adhesive on the back, and silicone-coated release paper as the backing paper. After printing, die-cutting and other processing, they become finished labels.

[0003] Existing self-adhesive labels do not have oil-proof properties. When the label is used in an oily environment, the oil will seep into the adhesive surface through the label surface and form a thin film on the adhesive surface. This film will hinder the direct contact between the adhesive and the surface of the object being labeled, thereby affecting the adhesion effect and even causing the label to fall off. Therefore, we provide an oil-proof self-adhesive label. Utility Model Content

[0004] The purpose of this invention is to provide an oil-resistant self-adhesive label to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil-resistant self-adhesive label, comprising a self-adhesive label body, wherein an oil-resistant layer is provided on the surface of the self-adhesive label body, the oil-resistant layer comprising a PE film layer and a PP film layer, an adhesive layer is provided on the back of the self-adhesive label body, and a locking ring is provided on the back of the self-adhesive label body and around the adhesive layer.

[0006] Using the above solution, water- and oil-repellent masterbatch is added to the PE film layer and PP film layer during the manufacturing process. This masterbatch contains fluorine compounds, which form a special microstructure on the surface of the self-adhesive label body, thereby reducing the surface energy of the self-adhesive label body. This makes it difficult for liquids such as water and oil to spread and adhere to the surface of the self-adhesive label body, thus giving the self-adhesive label body the function of preventing oil stains.

[0007] In a preferred embodiment of an oil-resistant self-adhesive label, a release liner is provided at the bottom of the adhesive layer, and the release liner has a tear-off area.

[0008] By using the above solution, the adhesive layer is protected by the release paper to prevent it from being contaminated before use, thereby reducing the adhesive layer's stickiness.

[0009] In a preferred embodiment of an oil-resistant self-adhesive label, the PE film layer is wrapped around the outer surface of the PP film layer, and the PP film layer is wrapped around the outer surface of the self-adhesive label body.

[0010] In a preferred embodiment of an oil-resistant self-adhesive label, the PE film layer and the PP film layer have the same thickness, both being 0.2mm-0.4mm.

[0011] In a preferred embodiment of an oil-resistant self-adhesive label, the top of the locking ring and the bottom of the self-adhesive label body are tightly fitted together and bonded together with an adhesive.

[0012] By using the above solution, the adhesive layer is used to limit and block the locking ring, preventing adhesive overflow.

[0013] In a preferred embodiment of an oil-resistant self-adhesive label, the PE film layer and PP film layer contain water- and oil-repellent masterbatch, and the water- and oil-repellent masterbatch contains fluorine-containing compounds.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model incorporates water- and oil-repellent masterbatch into the PE film layer and PP film layer during the manufacturing process. This masterbatch contains fluorine compounds, which form a special microstructure on the surface of the self-adhesive label body, thereby reducing the surface energy of the self-adhesive label body. This makes it difficult for liquids such as water and oil to spread and adhere to the surface of the self-adhesive label body, thus giving the self-adhesive label body the function of preventing oil stains.

[0016] 2. This utility model protects the adhesive layer by setting release paper, preventing the adhesive layer from being contaminated before use, thereby reducing the adhesive layer's stickiness. The adhesive layer also limits and blocks the locking ring, preventing adhesive overflow. Attached Figure Description

[0021] Please see Figure 1-3 An oil-resistant self-adhesive label includes a self-adhesive label body 1, the surface of which is provided with an oil-resistant layer 4, the oil-resistant layer 4 including a PE film layer 41 and a PP film layer 42, see [link to relevant documentation]. Figure 2 As shown, the PE film layer 41 wraps around the outer surface of the PP film layer 42, and the PP film layer 42 wraps around the outer surface of the self-adhesive label body 1. Figure 2 As shown, the PE film layer 41 and the PP film layer 42 have the same thickness, both ranging from 0.2mm to 0.4mm. The back of the self-adhesive label body 1 is provided with an adhesive layer 6, and a locking ring 5 is provided around the adhesive layer 6 on the back of the self-adhesive label body 1. Because water- and oil-repellent masterbatch is added to the PE film layer 41 and the PP film layer 42 during the manufacturing process, and this masterbatch contains fluorine compounds, these components will form a special microstructure on the surface of the self-adhesive label body 1, thereby reducing the surface energy of the self-adhesive label body 1, making it difficult for liquids such as water and oil to spread and adhere on the surface of the self-adhesive label body 1, thus giving the self-adhesive label body 1 an oil-proof function.

[0022] See Figure 1 As shown, a release paper 2 is provided at the bottom of the adhesive layer 6, and a tear-off area 3 is provided on the release paper 2. The release paper 2 protects the adhesive layer 6, preventing it from being contaminated before use, thereby reducing the stickiness of the adhesive layer 6. Figure 3 As shown, the top of the locking ring 5 and the bottom of the self-adhesive label body 1 are tightly attached and bonded by adhesive. The PE film layer 41 and the PP film layer 42 contain water- and oil-repellent masterbatch, and the water- and oil-repellent masterbatch contains fluorine-containing compounds.

[0023] When using, first pinch the tear-off part 3 and tear it to one side until the release paper 2 is separated from the bottom of the self-adhesive label body 1, and then stick the adhesive layer 6 to the surface of the substrate. The adhesive layer 6 is used to achieve the purpose of bonding. The release paper 2 protects the adhesive layer 6 and prevents it from being contaminated before use. Because water- and oil-repellent masterbatch is added to the PE film layer 41 and PP film layer 42 during the manufacturing process, this masterbatch contains fluorine compounds. These components will form a special microstructure on the surface of the self-adhesive label body 1, thereby reducing the surface energy of the self-adhesive label body 1, making it difficult for liquids such as water and oil to spread and adhere to the surface of the self-adhesive label body 1, so that the self-adhesive label body 1 has the function of preventing oil stains. Then, the adhesive layer 6 limits and blocks the locking ring 5 to prevent the overflow of adhesive.
