There are many factors that affect the transparency of PVC binding film. Comprehensive consideration in the development process
All kinds of factors, on the basis of the basic formula design 4 practical formula, the use of different formulations of the spectrophotometer test
The transmittance of the sheet, as shown in the table. As can be seen from the table, the formula 3 and formula 1 derived PVC binding film transparency
Slightly lower than the basic formula,
Other formulations are better than the basic formula. From the transparency, the formula 2, 4 can be used.
