If there are only a few bubbles on the side window, you can try to deal with them yourself.

气泡比较小可以用针刺破气泡，并用银 行 卡之类的物品轻轻推平；如果用针刺后，用塑料卡片推刮气泡依然不容易刮平，则说明气泡比较大，刺一个小孔出气太慢，可以用美工刀划一道口子，再轻轻推平；

The bubble is relatively small. You can pierce the bubble with a needle and gently push it flat with items such as bank cards; If it is still difficult to scrape the bubble with plastic card after acupuncture, it indicates that the bubble is relatively large and the air is too slow to puncture a small hole. You can make a cut with an art knife and then gently flatten it;

如果气泡是起在边缘位置，可以用塑料卡片轻轻把气泡往贴膜边缘推出贴膜。如果气泡比较多，一定要去贴膜店揭去重新贴。气泡一旦多了之后也会对车辆侧面的视线有所影响。

If the bubble starts at the edge, gently push the bubble out of the film towards the edge of the film with a plastic card. If there are many bubbles, be sure to go to the film shop to remove them and paste them again. Once there are many bubbles, it will also affect the line of sight on the side of the vehicle.

后挡玻璃起泡

Blistering of rear windshield

后挡玻璃上的贴膜容易起泡，原因是后车窗上布有除雾用的电热丝，一旦开启就相当于一直拿着“烧烤架烤贴膜”，导致贴膜经常热胀冷缩产生变形起泡，又或贴膜上的胶水经常被加热导致胶水内部的固化剂或反应基团失效，胶水变硬失粘产生气泡。

The film on the rear windshield is easy to blister. The reason is that the electric heating wire for defogging is distributed on the rear window. Once it is opened, it is equivalent to holding the "barbecue rack to bake the film", resulting in deformation and blistering due to frequent thermal expansion and cold contraction of the film, or the glue on the film is often heated, resulting in the failure of curing agent or reaction group inside the glue, hardening and viscosity loss of the glue, resulting in bubbles.

后挡玻璃的气泡处理起来和侧车窗相同，数量少可以尝试自己处理，如果数量多则要去贴膜店揭去后重新贴膜。

The air bubbles in the rear windshield are treated the same as those in the side window. If the quantity is small, you can try to deal with it yourself. If the quantity is large, go to the film store to remove it and apply the film again.

但由于后挡玻璃上存在除雾电热丝，并且部分没有夹层玻璃的车型电热丝和贴膜一样都在玻璃的内侧，本身也非常脆弱，很容易揭去贴膜的过程中被贴膜上的胶水拉坏。

However, there are demisting heating wires on the rear windshield, and some models without laminated glass are on the inner side of the glass like the film, which is also very fragile. It is easy to be damaged by the glue on the film in the process of removing the film.

1、刚贴好膜后有一段保护期，侧车窗一般在一周左右，而前后挡的时间为一个月左右。这时如果进行开关、清洗车窗或打开后车挡的除雾加热功能等可能就会造成贴膜起泡；

1. There is a protection period just after the film is pasted. The side window is generally about one week, while the front and rear blocks are about one month. At this time, if you switch, clean the window or open the defogging and heating function of the rear bumper, the film may bubble;

2、开空调对着车窗可能起泡；

2. When the air conditioner is turned on, the window may Blister;

3、保护期内，开空调时如果不注意对着车窗吹，可能会造成车窗和贴膜局部热胀冷缩，不能完全贴合而起泡；

3. During the protection period, if you don't pay attention to blowing against the window when turning on the air conditioner, it may cause local thermal expansion and cold contraction of the window and film, which can't fit completely and Blister;

4、在贴膜上贴真空贴可能造成贴膜损坏；

4. Sticking a vacuum paste on the film may cause damage to the film;

5、在玻璃内侧装真空贴或普通贴纸挂钩等用品并挂上物品，可能会由于外力作用，使得贴膜产生气泡甚部分脱落。

5. If vacuum stickers or ordinary sticker hooks are installed and hung on the inner side of the glass, the film may produce bubbles or even partially fall off due to external force.
