Abstract

This utility model discloses a backing-free thermal printing label paper, comprising a paper base, a heat insulation layer, a thermal color-developing layer, a silicone oil layer, a waterproof layer, and an adhesive layer. The thermal color-developing layer develops color when heated, meaning the label paper of this utility model is based on thermal paper. In use, the label paper can be directly adhered to the object, such as a package, via the adhesive layer. This utility model uses a backing-free thermal printing label paper, which, compared to traditional self-adhesive labels, avoids the waste of backing paper resources and reduces environmental pollution. Furthermore, the waterproof layer beneath the paper base effectively prevents the paper base from absorbing water, thus avoiding problems such as wrinkles.

Description

Technical Field

[0001] This utility model relates to the field of label paper technology, specifically to a backing paper-free thermal printing label paper. Background Technology

[0002] B2C and C2C e-commerce are increasingly penetrating everyone's daily life, and more and more people tend to buy their necessities online. Among these, labels are widely used in the logistics and express delivery industry. Traditionally, labels are self-adhesive labels, which have a two-layer structure: a face stock and a backing stock. When used, the face stock is peeled off from the backing stock and pasted onto the object. However, label manufacturers have gradually discovered that after traditional labels are used, the remaining backing stock has no value, which is not only a waste of resources but also causes environmental pollution.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a backing-less thermal printing label paper, comprising a paper base 1, a heat insulation layer 2, a thermal color-developing layer 3, a silicone oil layer 4, a waterproof layer 5, and an adhesive layer 6. The heat insulation layer 2 is disposed above the paper base 1, the thermal color-developing layer 3 is disposed above the heat insulation layer 2, the silicone oil layer 4 is disposed above the thermal color-developing layer 3, the waterproof layer 5 is disposed below the paper base 1, and the adhesive layer 6 is disposed below the waterproof layer 5.

[0020] It is understood that the aforementioned paper base 1 provides basic load-bearing capacity and strength for the label paper of this utility model, ensuring that the label paper remains stable and not easily damaged during the printing process. It also provides an adhesion base for the upper heat insulation layer 2, thermal color-developing layer 3, etc. The thermal color-developing layer 3 is the thermal color-developing layer, which develops color when heated. The paper base 1 and thermal color-developing layer 3 of this utility model are the same as those in existing thermal paper technologies, and will not be described in detail here.

[0021] The heat insulation layer 2 between the paper base 1 and the heat-sensitive color-developing layer 3 provides heat insulation protection for the paper base 1. The waterproof layer 5 below the paper base 1 effectively prevents the paper base 1 from absorbing water, thus avoiding problems such as wrinkles. In addition, the adhesive layer 6 is used to stick the label of this utility model onto the object to be labeled, such as express delivery. Specifically, the adhesive layer 6 can be a pressure-sensitive adhesive.

[0022] In addition, the aforementioned silicone oil layer 4 provides lubrication and anti-stick properties for the label paper, and protects the thermal color-developing layer 3 from moisture, thus preventing it from affecting the thermal printing effect. Preferably, the present invention may further include a protective layer 7, which is disposed between the silicone oil layer 4 and the thermal color-developing layer 3. This protective layer 7 provides waterproofing and prevents leakage of the silicone oil layer. Specifically, the protective layer 7 may be a polyethylene layer.

[0023] Preferably, in one embodiment, the backing-free thermal printing label of this invention has multiple easy-tear lines 8 evenly distributed along its length. It can be understood that the backing-free thermal printing label is divided into multiple unit blocks by the multiple easy-tear lines 8. The setting of the easy-tear lines 8 can facilitate the tearing off of the unit blocks of the backing-free thermal printing label, thereby improving the overall sticking efficiency of the label.

[0024] Furthermore, preferably, in another embodiment, the paperless thermal printing label of this invention is wound around the core tube, the core tube is disposed on the connecting shaft of the housing, and the housing is provided with a cutting blade. It can be understood that the above-mentioned connecting shaft and cutting blade facilitate the cutting and tearing operation of the paperless thermal printing label, and facilitate the cutting of label paper of different lengths, thereby making it easier to stick the label paper.

[0025] Of course, this embodiment is not limited to the backing paper being wound around the core. In some embodiments, the backing paper is folded by an easy-tear line, that is, the backing paper is stacked together by an easy-tear line.

[0026] Compared with existing technologies, this utility model provides a backing-free thermal printing label paper with the following advantages: The label paper of this utility model includes a paper base, a heat insulation layer, a thermal color-developing layer, a silicone oil layer, a waterproof layer, and an adhesive layer. The thermal color-developing layer can develop color when heated, meaning the label paper of this utility model is based on thermal paper. In use, the label paper can be directly pasted onto the recipient, such as a package, through the adhesive layer. This utility model uses a backing-free thermal printing label paper, which avoids waste of backing paper resources and reduces environmental pollution compared to traditional self-adhesive labels. Furthermore, a waterproof layer is provided beneath the paper base of this utility model, which effectively prevents the paper base from absorbing water and avoids problems such as wrinkles.
