Abstract
Description
Technical Field
[0001] This utility model relates to the field of transfer film, and more specifically, to a printing transfer film. Background Technology
[0002] Printed transfer film is a type of thin film material widely used in textiles, packaging, decoration and other industries. Its surface is usually printed with patterns or text, and the patterns are transferred to the target substrate through hot pressing or cold transfer. In the production process of transfer film, winding is one of the key processes, which directly affects the storage, transportation and subsequent processing quality of the product.
[0003] Currently, when printing transfer film is rolled up, the patterned side is usually facing inward (towards the core) to reduce damage to the pattern from external friction. However, since the surface of the transfer film is usually relatively smooth, especially for products using release agents or special coatings, its coefficient of friction is low. This makes it easy for the inner and outer rings to slip relative to each other after winding (commonly known as "loosening" or "slippage"). This phenomenon may be aggravated by factors such as vibration and temperature changes during transportation or storage, resulting in loosening and misalignment of the film roll. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a printing transfer film.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a printing transfer film, comprising a carrier layer and a plurality of pattern layers linearly arrayed on the carrier layer along the length direction of the carrier layer, wherein the width of the carrier layer is greater than the width of the pattern layers, and a plurality of anti-slip protrusions are provided at the edge of the carrier layer, the anti-slip protrusions being distributed on both sides of the pattern layers, and the anti-slip protrusions being linearly arrayed along the length direction of the carrier layer.
[0006] The present invention is further configured such that the anti-slip protrusion is integrally formed with the bearing layer.
[0007] The present invention is further configured such that the anti-slip protrusion is inclined relative to the length direction of the bearing layer.
[0008] The present invention is further configured such that the anti-slip protrusions are arranged in groups of two, and the two anti-slip protrusions in the same group have opposite inclination directions.
[0009] The present invention is further configured such that: a toothed line is provided between the pattern layer and the anti-slip protrusion.
[0010] The present invention is further configured such that the bearing layer is made of PET material.
[0011] In summary, this utility model has the following beneficial effects: when the transfer film is rolled up, the anti-slip protrusions increase the roughness of the transfer film surface, and the anti-slip protrusions increase the friction between the inner and outer rings of the transfer film, reducing the looseness of the transfer film. The carrier layer is a PET film, and the PET material has good tensile strength, ensuring the dimensional stability of the transfer film. Attached Figure Description

[0014] In the diagram: 1. Supporting layer; 2. Pattern layer; 3. Anti-slip bumps; 4. Toothed lines. Detailed Implementation
[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0016] Example: A printing transfer film, such as Figure 1 , Figure 2 As shown, the transfer film includes a carrier layer 1 and several pattern layers 2 linearly arrayed along the length of the carrier layer 1. The width of the carrier layer 1 is greater than the width of the pattern layers 2. Several anti-slip protrusions 3 are provided at the edge of the carrier layer 1. The anti-slip protrusions 3 are distributed on both sides of the pattern layers 2. The anti-slip protrusions 3 are linearly arrayed along the length of the carrier layer 1. The anti-slip protrusions 3 are integrally formed with the carrier layer 1. The anti-slip protrusions 3 are formed by hot pressing the carrier layer 1. The anti-slip protrusions 3 and the pattern layers 2 are respectively floating on both sides of the carrier layer 1. That is, on the side of the carrier layer 1 where the pattern layers 2 are provided, a concave structure is formed at the corresponding position of the anti-slip protrusions 3 to ensure that the pattern layers 2 can contact the surface to be transferred. When the transfer film is rolled up, the anti-slip protrusions 3 increase the roughness of the transfer film surface and increase the friction between the inner and outer rings of the transfer film, reducing the looseness of the transfer film.
[0017] like Figure 1 , Figure 2 As shown, the anti-slip protrusions 3 are inclined relative to the length direction of the bearing layer 1. The anti-slip protrusions 3 are arranged in pairs, and the two anti-slip protrusions 3 in the same group are inclined in opposite directions. The two adjacent anti-slip protrusions 3 form a figure-eight structure, which ensures that when the transfer film is wound up, the anti-slip protrusions 3 on the outer ring will overlap with the anti-slip protrusions 3 on the inner ring. Based on the softness of the transfer film itself, the concave and convex structures are interlocked at the edge of the transfer film roll, further increasing the friction between the inner and outer rings of the transfer film.
[0018] like Figure 1 , Figure 2 As shown, a toothed line 4 is provided between the pattern layer 2 and the anti-slip bumps 3. The carrier layer 1 is made of PET material, which is a PET film. PET material has good tensile strength, which ensures the dimensional stability of the transfer film. There is also an acrylic release agent layer between the pattern layer 2 and the carrier layer 1. There is also a hot melt adhesive layer on the side of the pattern layer 2 away from the carrier layer 1, which makes it easy for the pattern layer 2 to detach from the carrier layer 1 and adhere to the surface to be transferred. After the hot pressing of the anti-slip bumps 3 is completed, the toothed line 4 is pre-pressed between the array of anti-slip bumps 3 and the array of pattern layer 2. This makes it easy to separate and recycle the part where the anti-slip bumps 3 are when the transfer film is unfolded for use, so that the transfer film can be used as a regular transfer film.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
