Custom Printed Food Grade Microporous Packaging Bags Laser Punching​

Microporous breathable film is widely used in fruit and vegetable packaging. The breathable film is made by laser punching technology, which can effectively control the humidity inside and outside the packaging bag, prevent water vapor accumulation, maintain the freshness of fruits and vegetables, and delay the ripening and decay process of fruits.

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.
