UV AB Film (Paper Liner)

The structure of the AB film finished product is similar to the sandwich principle. It consists of three layers, namely the thin protective film on the surface, the UV film in the middle and the base paper. The base paper is a key factor in determining whether the UV DTF can be transferred completely and easily.
High-quality base paper must first have appropriate viscosity and hardness. It must not only firmly adhere to the pattern, but also easily separate the two. Even complex and tiny patterns can be easily transferred to the transfer paper. Second, it must have stable chemical properties. When the temperature and humidity of the surrounding environment change, its length and width can be kept unchanged to avoid wrinkling and deformation of the base paper, which will affect the pattern and the final printing effect.
UV DTF base paper is generally divided into two types: transparent base paper & white base paper. Next, I will explain the differences and advantages and disadvantages of the two in detail.

Transparent base paper:
Transparent base paper is a transparent release base paper. At the same number of meters, it is small in size, lighter in weight, and easy to transport. During the printing process, it is easier to monitor the printing effect and adjust it at any time.
However, it also has a disadvantage, that is, it has higher requirements for the printer’s paper feeding system and is prone to wrinkling.
White-backed paper:
The paper has a white background, which is more environmentally friendly. Because of its white background, the finished product display effect is better.
There are also disadvantages, such as larger volume and naturally heavier under the same number of meters; during the printing process, the monitoring page effect is poor. In addition, it should be noted that due to its material characteristics, it has good water absorption, so it is more susceptible to moisture and needs to be properly stored in a cool and dry environment.
