The structure and material of PET Color Wrap Film are introduced

PET Color Wrap Film does not mean that the material of the Car Wrapping Film is PET, PET Car Vinyl refers to the material of the bottom paper is PET, in fact, the use is still PVC base film, because this layer of PET release paper is to be torn off when it is affixed to the car body.

That is to say, the PET color changing film on the market is actually a PVC material, the difference is the bottom paper of the color changing film: PVC color changing film only has a thin layer of paper bottom paper, while PET color changing film uses PET bottom paper (PET release film).

1, About the history of car body color change film

First generation

It is mainly composed of ordinary PVC, glue and 120 grams of single shower paper, and the gas channel is mainly the money pattern gas channel.

Second generation

This kind of film calendering process, strong texture, close to the matt surface bright surface plating effect, mainly composed of ordinary PVC, glue and 120 grams of single shower bottom, the main gas channel for the "water cube gas tank".

The third generation

It is mainly a laminating process, double-layer structure, the bottom substrate is generally white or black, and different colors and metal glitter are coated on the substrate during production, and then the surface is pasted with a layer of ultra-thin transparent subfilm or bright film. Glue and 160 grams of double spray bottom paper, the main air channel is "diamond shaped air groove".

The fourth generation

Advanced technology, the film surface is flexible and silky, super stretching, easy construction. Using the latest PET backing paper, achieve 0 orange peel pattern, imported bottom adhesive water does not drop glue.

The fifth generation

It is made of TPU material, and has the repair function of car clothes, and the quality is more stable.

At present, the PET color changing film on the market is actually the fourth generation, and the ordinary PVC color changing film using paper backing paper is the third generation.

2. How to distinguish between color changing film paper and PET paper

There are two kinds of color changing film of paper base and PET base paper, and their color film layer is the same. Only the backing paper is different, PET is the backing paper, not the material.

Paper backing paper, at present, most of the color changing film is paper backing paper, and the orange peel pattern of the bright surface material is relatively obvious and cannot be avoided. The PET bottom color change film, the film surface is more flat, more bright, and no orange peel.

3, PET color film characteristics

① Professional advanced coating process, the color paste, color powder and pearlescent powder and other special effects combination, more color, more vivid, more textured products, and the process is stable and reliable.

② The stability of the molecular structure of the new generation of PET is excellent compared to the paper base, and there will not be too much change when the heat expands and cold contracts. After sticking on the surface of the car paint, it is closer to the original car paint, and basically achieve the effect of 0 orange peel lines.

③ At the same time to solve the flatness of the film surface and orange peel, simplify the difficulty of construction, make the film simpler and faster construction.

④ Compared with PVC products, the performance is more stable.
