Development and application of antibacterial properties of PE-LD materials in express bags
Publish Time: 2024-11-21
As a common polymer material, PE-LD has a wide range of applications in many fields, but in the field of express bags, the development and application of its antibacterial properties are gradually becoming a research hotspot.
PE-LD itself does not have an antibacterial effect. Its chemical structure lacks antibacterial functional groups and cannot directly kill or inhibit bacterial growth. However, by adding antibacterial agents, the antibacterial properties of PE-LD materials can be significantly enhanced. Antibacterial agents are substances that can kill or inhibit bacterial growth. By compounding with PE-LD, the antibacterial effect can be improved. This composite material not only retains the original excellent properties of PE-LD, but also adds antibacterial functions, thereby meeting the hygienic and safe needs of express bags during transportation.
In the manufacturing process of express bags, small packaging bags containing volatile antibacterial agents can be placed inside the express bags, or antibacterial coatings can be attached to the surface of PE-LD materials. In this way, during storage and transportation, the antibacterial agent can be slowly released into the express bag to maintain effective inhibition of bacteria. Commonly used antimicrobial agents include inorganic antimicrobial agents, organic antimicrobial agents and natural antimicrobial agents, which can kill or inhibit the growth of bacteria through different mechanisms of action.
In addition, PE-LD materials can also be combined with other environmentally friendly materials to form a composite structure of express bags. For example, PE-LD is used as a sandwich material and combined with polypropylene (PP) or polyethylene (PE) with good moisture barrier ability, which can not only enhance the barrier property of film formation, but also improve the moisture resistance of express bags. This composite structure not only improves the practicality of express bags, but also provides more possibilities for the development of their antimicrobial properties.
In summary, the development and application of antimicrobial properties of PE-LD materials in express bags has broad prospects. By adding antimicrobial agents, attaching antimicrobial coatings and combining with other environmentally friendly materials, the antimicrobial properties of express bags can be significantly improved to ensure the hygiene and safety of items during transportation. In the future, with the continuous advancement of the research and development of new antimicrobial agents and application technology, the antimicrobial properties of PE-LD materials in the field of express bags will be further improved.
