Description

Technical Field

[0001] The utility model relates to the technical field of labels, and particularly to a label that can avoid fading due to reaction with plasticizers. Background Technique

[0002] A label is a tool used to mark the classification or content of a product target, such as determining keywords for the target to facilitate self and others' search or positioning. Most of the labels referred to in the printing industry are printed materials used to identify the relevant descriptions of their own products, and most of them have adhesive on the back. However, there are also some labels without adhesive during printing, which can also be called labels. Labels with adhesive are commonly known as "self-adhesive labels". The label problem after instrument calibration is a label stipulated by the state (or within one's own province), and the label can clearly explain the detailed situation of the instrument after calibration. Labels are also divided into physical labels, network labels, and electronic labels. Physical labels are labels pasted on the surfaces of various tangible objects, facilitating people to identify the information of the pasted objects.

[0003] Thermal label paper is a widely used label material. In real life, thermal label paper is often used in the food industry, pasted on the inside or outside of food wrap and plastic bags. However, plasticizers are inevitably added to food wrap and plastic bags, and the plasticizers will migrate out of the plastic material during storage, dissolving the text and other information on the thermal label paper, affecting people's reading of the content on the label. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a label that can avoid fading due to reaction with plasticizers, so as to solve the problem that plasticizers dissolve the text and other information on the thermal label paper and affect people's reading of the content on the label in the related technology.

[0005] To achieve the above purpose, according to one aspect of the utility model, there is provided a label that can avoid fading due to reaction with plasticizers, including: a surface layer, the surface layer is composed of a face paper and a protective layer, the face paper is used to store label information, and the protective layer separates the surface of the face paper from external plasticizers;

[0006] An isolation layer, the isolation layer is fixedly arranged on the back of the surface layer, the isolation layer separates the back of the face paper from external plasticizers, and the isolation layer includes rectangular strips and folded strips.

[0007] Further, the protective layer includes a first protective layer, a second protective layer, and a third protective layer. The first protective layer is fixedly arranged on both the upper and lower surfaces of the face paper, the second protective layer is fixedly arranged on the upper surface of the first protective layer above the face paper, and the third protective layer is fixedly arranged on the upper surface of the second protective layer.

[0008] Further, there are two rectangular strips which are arranged in parallel and are respectively fixed at both ends of the back surface of the surface layer along the short side. An adhesive is fixed on the back surface of the rectangular strip for pasting the label onto an article.

[0009] Further, the folded strip is located between the two rectangular strips and is fixed in the middle of the back surface of the surface layer. An adhesive is fixed on the back surface of the folded strip for pasting the label onto an article.

[0010] Compared with the prior art, the present utility model has the following beneficial effects: The folded strip and the rectangular strip separate the surface layer from the object to be pasted, increasing the distance between the two. Even if a plasticizer precipitates from the object to be pasted, it cannot move to the surface layer, preventing the information on the label from reacting with the precipitated plasticizer and protecting the content of the label from being eroded and faded by the plasticizer. If the article with the label is wrapped with a plastic wrap, the surface layer of the label directly contacts the plastic wrap. The third protective layer plays a first isolation role for the plasticizer in the plastic wrap. Some free plasticizers enter the second protective layer after passing through the third protective layer. The second protective layer is made of paraffin oil. The relatively thick paraffin oil absorbs and isolates most of the plasticizers, further reducing the free plasticizers. Only a very small amount of plasticizers reach the first protective layer after passing through the paraffin oil and are blocked again. The plasticizers passing through the first protective layer are negligible and have a minimal corrosive effect on the label, and the label will not fade due to the action of the plasticizer.

[0018] In order to further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following describes in detail the specific implementation manner, structure, features and their effects of the present utility model with reference to the accompanying drawings and preferred embodiments.

[0019] Please refer to Figures 1 to 3, this embodiment provides a label that can avoid fading due to reaction with plasticizers, including: a surface layer 1, which consists of a face paper 3 and a protective layer. The face paper 3 is used to store label information, and the protective layer separates the surface of the face paper 3 from external plasticizers. Protective layers are provided on both the upper and lower surfaces of the face paper 3 to enhance the isolation degree between the face paper 3 and external plasticizers;

[0020] An isolation layer 2 is fixedly provided on the back of the surface layer 1 to increase the distance between the surface layer 1 and items containing plasticizers such as external plastic wrap, and prevent plasticizers from corroding the surface layer 1. The isolation layer 2 separates the back of the face paper 3 from external plasticizers. The isolation layer 2 includes rectangular strips 201 and folded strips 202. Both the rectangular strips 201 and the folded strips 202 are made of sponge glue. The sponge glue has a certain strength to support the surface layer 1, and the sponge glue has a small density and light weight. Although the thickness of the label increases significantly, its weight changes very little.

[0021] The protective layer includes a first protective layer 4, a second protective layer 5, and a third protective layer 6. The first protective layer 4 and the third protective layer 6 are made of polystyrene. Since polystyrene does not contain plasticizers, while isolating external plasticizers, it can also protect the face paper 3 from being corroded by oil stains. The second protective layer 5 is made of paraffin oil, which is colorless and transparent and does not contain plasticizers. A thick layer of paraffin oil increases the difficulty for free plasticizers to penetrate, and does not affect the reading of the information printed on the face paper 3. The first protective layer 4 is fixedly provided on both the upper and lower surfaces of the face paper 3 to isolate the face paper 3 from the outside and prevent it from being contaminated by oil stains, etc. The second protective layer 5 is fixedly provided on the upper surface of the first protective layer 4 above the face paper 3 to increase the distance between the face paper 3 and the outside and reduce the possibility of plasticizers coming into contact with the face paper 3. The third protective layer 6 is fixedly provided on the upper surface of the second protective layer 5 to protect the second protective layer 5 from being contaminated and at the same time increase the isolation strength against plasticizers.

[0022] There are two rectangular strips 201 in total and they are arranged in parallel, respectively fixed at both ends of the back of the surface layer 1 along the short side, playing a supporting role for the surface layer 1. An adhesive is fixedly provided on the back of the rectangular strip 201 for pasting the label onto an item.

[0023] The folded strip 202 is located between the two rectangular strips 201 and is fixedly provided in the middle of the back of the surface layer 1, playing a supporting role for the surface layer 1. An adhesive is fixedly provided on the back of the folded strip 202 for pasting the label onto an item.

[0024] When the label needs to be pasted on the surface of the plastic wrap or plastic bag, tear off the corresponding label from the label paper, paste the rectangular strip 201 at one end of the label on the surface of the object to be pasted, and press it flat with your finger to make the rectangular strip 201 completely adhere to the surface of the object to be pasted, preventing air bubbles from being generated between the rectangular strip 201 and the object to be pasted, thus affecting the firmness of the label paste. After the rectangular strip 201 at one end is firmly pasted, hold the surface layer 1 with your finger and slide along the surface layer 1, moving from one end of the pasted rectangular strip 201 to the other end to eliminate the air bubbles between the folded strip 202, the rectangular strip 201 and the object to be pasted, enhancing the adhesion between the label and the object to be pasted, and at the same time avoiding wrinkles on the surface layer 1 due to uneven pasting, which affects the reading of the label content. The folded strip 202 and the rectangular strip 201 separate the surface layer 1 from the object to be pasted, increasing the distance between the two. Even if the object to be pasted has plasticizer precipitation, it cannot move to the surface layer 1, preventing the possibility of the information on the label reacting with the precipitated plasticizer, and protecting the content of the label from being eroded and faded by the plasticizer; if the plastic wrap wraps the item with the label pasted on it, the surface layer 1 of the label directly contacts the plastic wrap, and the third protective layer 6 plays the first isolation role for the plasticizer in the plastic wrap. Some free plasticizers enter the second protective layer 5 after passing through the third protective layer 6. The second protective layer 5 is made of paraffin oil, and the relatively thick paraffin oil absorbs and isolates most of the plasticizers, further reducing the free plasticizers. Only a very small amount of plasticizers reach the first protective layer 4 after passing through the paraffin oil and are blocked again. The plasticizers passing through the first protective layer 4 are negligible, and the corrosion effect on the label is extremely small, and the label will not fade due to the action of the plasticizer.

[0025] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention in any form. Although the present invention has been disclosed as above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to it as equivalent embodiments within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
