选择塑封膜分为尺寸和厚度，一般国内常规尺寸有3寸、5寸、6寸、7寸、8寸、A4、A3，国外常规尺寸有2R、A6、A5、A4、A3。特殊规格和特殊厚度都可以按客户需求定制。

      本公司从40mic-250mic都可以生产(1丝=1C=10mic=0.01mm，mic微米是国际厚度名称)，厚度越厚，塑封后手感越硬，其中80mic为常用厚度，软硬适中。按尺寸来看，塑封膜一般比塑封资料大6-10mm，必须留有足够的边距，塑封之后才不容易脱胶。

      塑封膜的厚度代表塑封之后资料的软硬度，不同的厚度需要对应不同的塑封机温度。例如普通80g纸张厚度，用50mic塑封膜塑封，塑封机温度需调在110-120℃左右，塑封后手感软，适合对硬度要求不高的客户；用80mic塑封膜塑封，塑封机温度需调在120-130℃左右，塑封后软硬手感适中；用100mic塑封膜塑封，塑封机温度需调在130-135℃左右；用150mic塑封膜塑封，塑封机温度需调在150℃左右，可用于证件菜单对硬度要求高的产品，塑封之后硬度提升。

The main specifications of a laminating film are the sheet size & thickness.

Generally, international standard sizes are 2R, A6, A5, A4, A3. Special sizes and thickness can be customized according to different needs.

We can produce from 40mic to 250mic, 80mic with moderate hardness is the most popular thickness for common usage, the thicker the laminating film, the harder it would feel after laminating. 

In terms of size, the laminating film should be 6-10mm larger than the material sizes on each side.

The thickness of the film decides the softness and hardness of the material after laminating; The laminating temperature is also different for different thickness film. 

For example, if we laminate an ordinary 80g paper with a 50mic laminating pouched film, the temperature of the laminator needs to be adjusted at about 110-120°C, it would have a qutie soft feeling after laminating; If we uses a 80mic laminating pouched film, the temperature of the laminator needs to be adjusted at about 120-130°C, it would have a morderate soft feeling after laminating; If we uses a 100mic laminating pouched film, the temperature of the laminator needs to be adjusted at about 130-135°C, it would have a hard feeling after laminating; If we uses a 150mic laminating pouched film, the temperature of the laminator needs to be adjusted at about 150°C, it would have a quite hard feeling after laminating so it usually can be used for cards or menues laminating which has a higher hardness requirements.
