The blister is made of high-pressure polyethylene as the main raw material, and the auxiliary materials such as whitening agent and pore opening agent are added. The blister product is extruded at a high temperature of about 230 ℃. It is a light, transparent, nontoxic and tasteless new plastic packaging material. Also called bubble pad. What's the relationship between bubble size and thickness? Let's talk about it now.
The diameter of bubbles is generally 6mm, 10mm and 28mm, and there are also 20mm (relatively rare) and cardioid bubbles (with special shape and less compression resistance than round bubbles). The most common one is the diameter of 10mm foam and the wide range of compressive resistance. 6mm is characterized by beautiful appearance and neat bubbles. It is suitable for the outer packaging of telephone and other products, mainly anti-wear and shock absorption. The bubble diameter is 20-28mm, which belongs to large bubble. The higher the bubble characteristics, the thicker the general film thickness will be, and the better the buffer impact effect of bubble bag.
厚度，这个厚度不是气泡的高度，而是膜的厚度(几股)。一般来说，初来乍到的人在这方面会有歧义。因为气泡膜的厚度不能直接用千分尺测量，所以一般使用多少克每平方米的说法(类似于A4纸有70g、80g)。克越重，压力越大，手的感觉就越硬。典型的10毫米泡沫厚度变化从35克/㎡100 g /㎡。也可以做厚,如200 g /㎡,但用户的成本太高,所以非常小。作为一个经验法则65 g - 85 g /㎡厚度是一个不错的选择,压缩好,成本不高。更常见的厚度6毫米泡沫的规模也从35克/㎡100 g /㎡。根据经验，50g-70g/ SQM是适合这种囊泡的大小。20-28mm泡沫厚度,直径从100 g - 200 g /㎡。常用的是200克/㎡。因为气泡很大，如果厚度太薄，很容易破裂。所以厚度通常比囊泡厚。
Thickness, this thickness is not the height of the bubble, but the thickness of the film (several strands). Generally speaking, newcomers may have different opinions in this respect. Because the thickness of bubble film can not be measured directly with micrometer, it is generally used to say how many grams per square meter (similar to that of A4 paper, 70g, 80g). The heavier the gram, the more pressure, the harder the hand feels. The typical 10 mm foam thickness varies from 35 g / T 100 g / C. It can also be made thick, such as 200 g / m2, but the user's cost is too high, so it is very small. As a rule of thumb, the thickness of 65g - 85g / ㎡ is a good choice with good compression and low cost. The most common thickness of 6 mm foam is also from 35 g / h 100 g / C. According to experience, 50g-70g / sqm is suitable for the size of this kind of vesicle. The thickness of 20-28mm foam is from 100 g to 200 g / C. 200 g / m2 is commonly used. Because the bubble is very large, if the thickness is too thin, it is easy to crack. So the thickness is usually thicker than the vesicle.
