The influence of the quality of the base material masking paper on the masking tape

2024-07-31

What impact does the quality of the base masking paper have on the production of masking tape products! There are several aspects that need to be paid attention to:


1. Dry and wet tension: Dry tension is to ensure that the base masking paper is not broken during unwinding, rewinding, slitting and use; wet tension is to ensure that the base masking paper is not broken during coating and gluing. Dry and wet tension should be tested separately in the longitudinal and transverse directions, because the aspect ratio of the base paper of different manufacturers is quite different, the largest aspect ratio can reach 3.2, and the smallest is 1.2. The longitudinal tension is the most important, and too small transverse tension will also affect the use.


2. Impermeability: When applying water-based adhesive or solvent-based adhesive, the adhesive cannot penetrate to the back.


3. Absorption of glue: It is necessary to ensure that a certain thickness of glue layer can be coated on the surface of the paper raw material. Some paper has excessive or improper anti-seepage or waterproof treatment, resulting in poor absorption of glue. When passing through the scraper or scraper process, the glue cannot be hung or is easily taken away, and the paper surface cannot reach a certain amount of glue, thus affecting the quality of the masking tape product.


4. Temperature resistance: Masking tape has different temperature resistance levels. The temperature resistance of normal temperature type is below 60℃; the temperature resistance of medium temperature type is about 80℃; the temperature resistance of high temperature type is about 100℃. Choose the appropriate temperature resistance level according to the purpose and use conditions of the masking tape.


5. Softness: Masking tape must be able to achieve good adhesion with the surface to be adhered, and the softness of the base material masking paper must be good.


6. Glue bonding: Some masking papers with poor base materials have poor bonding with the coating glue. After coating into a roll, the adhesive layer is easily transferred or the adhesive is easily detached from the paper surface during use.
