Graphene Fresh Keeping Film

Five principles of graphene sterilization:
1. Physical cutting (nano knife): The sharp physical edges of graphene cut the surface of bacteria and viruses, destroying cell walls and membrane structures, causing leakage of intracellular substances and metabolic disorders, and ultimately leading to the death of bacteria and viruses.
2. Destroy cell membrane: Extraction of membrane surface components. Graphene has a large specific surface area and hydrophobicity. It can effectively contact or insert phospholipid molecules on the surface of bacteria and viruses, thereby destroying the cell membrane structure.
3. Physical capture: Graphene will isolate the bacteria from the surrounding medium by wrapping, thereby blocking their proliferation and achieving a bacteriostatic effect.
4. Oxidative stress: In the process of contact with bacteria, graphene surface defects and sharp edge structures will induce bacteria to produce reactive oxygen species, leading to metabolic disorders.
5. Charge conduction: The charge is transferred to the surface of bacteria through graphene, which destroys the physiological activities and functions of cell membranes, causes metabolic disorders of bacteria, and promotes their death.

Graphene fresh-keeping bag (film) sterilization effect: Graphene anti-bacterial fresh-keeping bag (film) makes full use of the antibacterial principle of graphene, which can remove Salmonella, Shigella, Listeria, and large intestine that are common in refrigerator food and various foods. Bacillus, Staphylococcus aureus and other bacteria are inactivated and killed, with an antibacterial rate of 99.9% (see inspection report), which can achieve long-term antibacterial preservation of food, and will comprehensively improve and improve the antibacterial preservation of fresh food, fruits and vegetables, etc. Time and quality.
