1. Smell close to the thermal insulation film: you can ask the store for the leftover materials of the thermal insulation film. Smell close to the thermal insulation film. If you smell a strong pungent smell, you can basically judge it as a poor quality film, which is mainly caused by the use of hazardous chemical adhesive layer in the film making process.

2、观察隔热膜外观：劣质膜通常情况下颜色较深，这样可阻隔大量的可见光，经过暴晒后，膜的颜色会越来越淡，主要是因为膜的胶层经过暴晒后挥发导致色彩出现变化造成的。更可怕的是，劣质膜采用普通廉价的原料和固化工艺，会在日晒下局部融化，产生光畸变，给驾驶带来非常大的隐患。

2. Observe the appearance of the thermal insulation film: the inferior film is usually dark in color, which can block a lot of visible light. After exposure, the color of the film will become lighter and lighter, mainly because the color change caused by the volatilization of the adhesive layer of the film after exposure. What is more frightening is that the low-quality film adopts ordinary and cheap raw materials and curing process, which will locally melt under the sun and produce light distortion, which brings great hidden dangers to driving.

3、密切留意贴膜效果：如果贴膜后一段时间出现气泡，摸起来不平整，或者后挡玻璃窗的贴膜使用几个月后就出现水波纹/橘皮纹，基本可以判定为劣质膜。这由于劣质膜材料不稳定，在阳光下会分解老化，产生气泡/水波纹/橘皮纹，既影响美观，且严重影响视线。

3. Pay close attention to the film effect: if bubbles appear after the film is applied for a period of time, or the film on the rear windshield appears water ripple / orange peel after several months of use, it can be judged as inferior film. This is because the poor quality film material is unstable and will decompose and age under the sun, resulting in bubbles / water ripples / orange peel, which not only affects the appearance, but also seriously affects the line of sight.
