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).

　　其中更常见的是10mm泡径的，抗压能力适用范围广。6mm的特点是外观漂亮，泡泡看起来非常整齐，适合电话机等有外包装的产品，主要防磨损，捎带减震。

　　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泡径，都是属于大泡了，特点是泡高较高，一般膜的厚度也会做的更厚，气泡袋缓冲防震效果更好。

　　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.

　　下图从左右分别是6mm、10mm、28mm的泡径。

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

　　2、厚度：这个厚度不是说泡的高度，而是膜的厚度（几丝几丝的）。一般新人容易在这有歧义。气泡膜因为没法用千分尺直接测量厚度，所以一般采用多少克每平米的说法（类似A4纸有70g，80g）。克重越大，抗压越强，手感越硬。下图中，1、2两片气泡膜大小一样，泡高相同，就是一个轻一个重。

　　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泡径常见的厚度从35g/㎡到100g/㎡。还可以做的更厚，比如200g/㎡，但是对使用者来说，成本太高，所以很少。按经验来说65g-85g/㎡的厚度，都是不错的选择，抗压既不错，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泡径常见的厚度基本也是从35g/㎡到100g/㎡。按经验来说，这种小泡用50g-70g/㎡就比较合适。

　　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泡径的厚度，从100g-200g/㎡都有使用。更常用是200g/㎡。因为泡大，厚度如果太薄，很容易爆。所以常用厚度相对小泡中泡都更厚。

　　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.
