1. Bubble diameter: generally, it is mainly 6mm, 10mm, 28mm. There are also 20mm (not very common) and cardioid bubbles (special appearance, not as compressive as round bubble).

　　其中更常見的是10mm泡徑的，抗壓能力適用范圍廣。6mm的特點是外觀漂亮，泡泡看起來非常整齊，適合電話機等有外包裝的產品，主要防磨損，捎帶減震。

　　Among them, the most common one is the one with a bubble diameter of 10 mm, which has a wide range of compressive capacity. 6mm is characterized by beautiful appearance and very neat bubble. It is suitable for telephone and other products with external packaging, mainly anti-wear and shock absorption.

　　20-28mm泡徑，都是屬于大泡了，特點是泡高較高，一般膜的厚度也會做的更厚，氣泡袋緩沖防震效果更好。

　　20-28mm bubble diameter, all belong to big bubble, characterized by high bubble height, the thickness of general film will be thicker, and the bubble bag has the best cushioning and shockproof effect.

　　下圖從左至右分別是6mm、10mm、28mm的泡徑。

　　The following figure shows the bubble diameter of 6mm, 10mm and 28mm from left to right.

　　2、厚度：這個厚度不是說泡的高度，而是膜的厚度（幾絲幾絲的）。一般新人容易在這有歧義。氣泡膜因為沒法用千分尺直接測量厚度，所以一般采用多少克每平米的說法（類似A4紙有70g，80g）?？酥卦酱?，抗壓越強，手感越硬。下圖中，1、2兩片氣泡膜大小一樣，泡高相同，就是一個輕一個重。

　　2. Thickness: this thickness is not the height of the bubble, but the thickness of the film (several threads). It's easy for new people to have ambiguity here. Because it is impossible to measure the thickness of bubble film directly with micrometer, it is generally used to say how many grams per square meter (similar to 70g, 80g for A4 paper). The bigger the weight, the stronger the pressure and the harder the hand feel. In the figure below, the size and height of the two bubble films are the same, that is, one is light and the other is heavy.

　　a） 10mm泡徑常見的厚度從35g/㎡到100g/㎡。還可以做的更厚，比如200g/㎡，但是對使用者來說，成本太高，所以很少。按經驗來說65g-85g/㎡的厚度，都是不錯的選擇，抗壓既不錯，成本又不高。

　　a) The common thickness of 10 mm bubble diameter ranges from 35g / ㎡ to 100g / ㎡. It can also be made thicker, such as 200g / ㎡, but for users, the cost is too high, so it is rare. According to experience, the thickness of 65g-85g / ㎡ is a good choice, with good compression resistance and low cost.

　　b） 6mm泡徑常見的厚度基本也是從35g/㎡到100g/㎡。按經驗來說，這種小泡用50g-70g/㎡就比較合適。

　　b) The common thickness of 6mm bubble diameter is also from 35g / ㎡ to 100g / ㎡. According to experience, this kind of vesicle is suitable for 50g-70g / ㎡.

　　c） 20-28mm泡徑的厚度，從100g-200g/㎡都有使用。更常用是200g/㎡。因為泡大，厚度如果太薄，很容易爆。所以常用厚度相對小泡中泡都更厚。

　　c) The thickness of 20-28mm bubble diameter can be used from 100g-200g / ㎡. The most commonly used is 200g / ㎡. Because the bubble is big, if the thickness is too thin, it is easy to explode. Therefore, the common thickness is thicker than that in the vesicles.
