Composite bags

The various characteristics of the material together to improve the permeability of the packaging material, moisture permeability, oil resistance, water resistance, chemical resistance, to play pest control, dust, microbes, light, fragrant, smelly And other odor isolation, as well as heat, cold, impact resistance with better mechanical strength and processing performance, and a good printing and decorative effect.

In the form of packaging: three side seal, yin and yang bags, in the closure, pillow bags, five side sealed bags, eight side sealed bags, self-reliance bags, zipper bags, straw bags,

Functional classification: high Yin diaphragm bags, cooking film bags, antistatic film bags, antibacterial film bags, anti-fog film bags, vacuum bags, chemical film bags, deoxygenated packaging bags,
