Label resistant to discoloration from reaction with plasticizer

Abstract

The present utility model relates to the technical field of labels, and specifically relates to a label resistant to discoloration from a reaction with a plasticizer. Zigzag support strips and rectangular support strips separate a face layer from an item being labeled, thereby increasing the distance between the face layer and said item, preventing label information from reacting with migrated plasticizers, and protecting label content from being eroded by the plasticizers and fading. If plastic wrap is used to wrap an item being labeled, a face layer of the label is in direct contact with the plastic wrap. A third protective layer acts as a first-layer barrier against plasticizers in the plastic wrap. A portion of free plasticizers penetrate the third protective layer and enter a second protective layer made of paraffin oil. The thick paraffin oil absorbs and isolates the majority of the plasticizers, thereby further reducing the free plasticizers. A very small portion of the plasticizers penetrate the paraffin oil to reach a first protective layer and are then blocked again. The amount of the plasticizers penetrating the first protective layer is negligible, resulting in minimal corrosive effects on the label and thus preventing plasticizer-induced label discoloration.

[0018] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model are described in detail as follows in combination with the drawings and preferred embodiments.

[0019] Referring to FIG. 1 to FIG. 3, the present embodiment provides a label which can avoid fading due to reaction with plasticizer, comprising: a surface layer 1, the surface layer 1 is composed of a surface paper 3 and a protective layer, the surface paper 3 is used to store label information, and the protective layer separates the surface of the surface paper 3 from external plasticizer, the upper and lower surfaces of the surface paper 3 are both provided with the protective layer, thereby enhancing the isolation degree of the surface paper 3 from external plasticizer;

[0020] An isolation layer 2 is fixedly arranged on the back of the surface layer 1, thereby increasing the distance between the surface layer 1 and external plasticizer-containing articles such as plastic wrap, preventing the plasticizer from corroding the surface layer 1, and separating the back of the surface paper 3 from external plasticizer, the isolation layer 2 comprises rectangular struts 201 and folded struts 202, the rectangular struts 201 and the folded struts 202 are both made of sponge rubber, the sponge rubber has a certain strength and can support the surface layer 1, and the sponge rubber has small density and light weight, so that the thickness of the label is obviously increased, but the weight of the label is little changed.

[0021] The protective layer comprises 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 the polystyrene does not contain plasticizer, the polystyrene can separate external plasticizer and protect the surface paper 3 from being corroded by oil stains, the second protective layer 5 is made of paraffin oil, the paraffin oil is colorless and transparent and does not contain plasticizer, a thick layer of the paraffin oil increases the difficulty of penetration of free plasticizer and does not affect reading of information printed on the surface paper 3, the upper and lower surfaces of the surface paper 3 are both fixedly provided with the first protective layer 4, thereby separating the surface paper 3 from the outside and preventing oil stains and the like from polluting the surface paper 3, the second protective layer 5 is fixedly arranged on the upper surface of the first protective layer 4 above the surface paper 3, thereby increasing the distance between the surface paper 3 and the outside and reducing the possibility of contact between the plasticizer and the surface paper 3, and the third protective layer 6 is fixedly arranged on the upper surface of the second protective layer 5, thereby protecting the second protective layer 5 from being polluted and increasing the isolation strength of the second protective layer 5 to the plasticizer.
