The two printing processes of UV dtf film are paired with corresponding materials. Before, there were glue options for the direct injection process. Here we talk about the AB film material of the AB film process.
Due to the high popularity of the product and the large market, many domestic material coating factories have begun to study AB film. In fact, the quality of uv dtf film is uneven. How to choose an AB film with good quality, low price, and strong adhesion? The key to making the perfect pattern.
The structure of the finished AB film and the self-adhesive material is based on the sandwich principle, two layers of material sandwich glue, but the principle of use is different: the bottom paper of the self-adhesive film is the waste layer, while the bottom paper and transfer film of the uv dtf film are both Abandoned layer.
Therefore, many manufacturers use cheap materials for the bottom paper and transfer film in order to pursue profits. You need to master the following knowledge points:
(1) Glue plays a decisive role
Glue determines whether the finished product will be curled, cracked, drawn, and overflowed. Before printing the finished product, it is impossible to tell whether the glue is good or bad. Apart from buying it back for testing, the only option is not to be greedy for cheap, and try to choose mature ones that have been verified by the market. It is best to look at the finished product of the supplier first, try it out, and then purchase in batches step by step.
(2) Bottom paper
The key to determining the difficulty of uv dtf film transfer is not only the glue but also the backing paper, so the following conditions must be met when selecting:
1. The backing paper is made of high-quality Singela release paper
2. The texture is dense and uniform, with good internal strength and light transmittance
3, with high temperature, moisture, oil and other functions
4. Can be firmly combined with glue to stick to the pattern, strong adhesion, easy to peel off when reposting
(3) Transfer film
The transfer film is also the B film, that is, the transparent waste film that is covered on the A film to transfer the pattern of the printing layer. Because it is a waste material, many people use the sealing film on the thermal lamination machine, which is also the reason for the unstable quality.
The thickness and high-temperature resistance of the film are very important, which determine whether the finished product is curled when placed, or the film does not fall off after transfer (not completely separated from the pattern).
After understanding the precautions, you can avoid quality problems in production, that is, sharpening the knife without accidentally chopping wood. The specific process is roughly the same, and the core technology is in the selection of materials. Reasonable selection of materials can avoid trial and error costs.
