Customized Microporous Self-Adhesive Packaging Bags Are Safe And Reliable For Vegetable Food Packaging​

The micropores are small and uniform in size: Generally speaking, the diameter of the micropores on the microporous bag is usually between 0.01 mm and 0.4 mm. In some special applications, the pore size can be as small as micrometer level12. At the same time, in order to ensure the stability of various properties, the micropores are distributed evenly on the bag body, and the spacing between the holes also has certain standards, such as 3-10 mm for row spacing and 3-20 mm for column spacing.

Laser drilling:
 

Using the high energy density of laser, tiny parts of the bag material are instantly vaporized to form micropores. This method can accurately control the pore size and pore distribution density, and can produce micropores with very small and uniform pores, which is suitable for occasions with high requirements for air permeability and dust and water resistance.
