Bio-Mark is used in laboratories for the collection of biohazardous waste for disposal. The product is made from a special composite material, and through a unique manufacturing process, it possesses higher mechanical strength than ordinary sterilization bags, being tough, puncture-resistant, and capable of withstanding sustained high temperatures and high pressure. The specially designed double-sealed bottom ensures excellent sealing, is leak-proof, and has high mechanical strength. The interface can bear significant weight without rupturing even when the bag is full and lifted. The bag body is printed with warning symbols and the word "BIOHAZARD".
