3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Automobile paint protection film
A film layer, which usually contains a three-layer functional structure of adhesive
layer, base film, surface coating; is pasted on the car part or the whole car; has a
certain degree of protective and/or decorative effect on the automobile paint and the
outer paint surface of parts.
3.2
Dent
Unrecoverable traces, which are formed on the surface of the film layer, due to
external force extrusion.
3.3
Flow line
Traces, which are formed on the film surface, due to uneven production process.
3.4
Crease
4.1.2 According to the reflective characteristics of the surface, it is divided into:
a) Glossy automobile paint protection film;
b) Matte automobile paint protection film;
c) Pearlescent automobile paint protection film.
4.2 Marking
The product packaging shall be marked in the order of product name, material, color,
surface reflective characteristics, standard number. Use PPF to represent the automobile
paint protection film; use English abbreviations to represent the material; use English
words to represent the color; use Chinese pinyin abbreviations to represent the surface
reflective properties, that is, LG, YG, ZG represent glossy, matte, pearlescent,
respectively.
Example 1:
Colorless gloss thermoplastic polyurethane (TPU) type automobile paint protection film is
marked as: PPF-TPU-Clear-LG-QC/T xxxxx-xxxx.
Example 2:
Black matte polyvinyl chloride (PVC) type automobile paint protection film is marked as: PPF-
PVC-Black-YG-QC/T xxxxx-xxxx.
Example 3:
White pearlescent polyvinyl chloride (TPH) type automobile paint protection film is marked as:
PPF-TPH-White-ZG-QC/T xxxxx-xxxx.
