Black carbon black light-shielding masterbatch is blended into raw materials for full light blockage fabric that completely blocks natural light and UV penetration through the bag, fundamentally preventing photo-induced oxidation, discoloration and failure of light-sensitive materials.
The black fabric also features anti-UV aging performance to resist aging and cracking under outdoor sunlight. Equipped with sealed inner liner for double light shielding, the bag spout can be tightly tied to stop light infiltration from openings.
