Definition:
An antimicrobial masterbatch is a functional plastic pellet designed as an additive for plastic products. It imparts antimicrobial properties to the final product, helping to inhibit and kill bacteria and other microorganisms. This ensures the protection of both the plastic product and the user’s health and cleanliness needs.
Composition:
It mainly consists of a polymer carrier resin (such as PE, PP, ABS, TPE, etc.) and a high concentration of special antimicrobial agents. It may also contain dispersants, stabilizers, and other additives to ensure the even dispersion and effectiveness of the antimicrobial agents.
Application:
During the production of plastic products, only 1%-5% of the antimicrobial masterbatch is added. It can be processed using standard equipment, creating antimicrobial products without altering the existing manufacturing process, thus greatly simplifying the production of antimicrobial products.
The key distinction between antibacterial and antimicrobial substances lies in the microorganisms they target. Antibacterial solutions combat a wide range of harmful bacteria, including E. coli and MRSA. Antimicrobial formulations, however, reduce bacteria, mold, and algae. Unlike antibacterial agents, antimicrobial substances provide broader protection, effectively safeguarding products from more types of microorganisms. Their versatile, wide-spectrum performance makes them ideal for hygiene-sensitive settings like schools, hospitals, and commercial kitchens. Learn more today.
Antimicrobial agents are substances that kill or inhibit the growth of microorganisms like bacteria, fungi, and viruses. There are four main types: inorganic agents (e.g., silver, copper), organic agents (e.g., antibiotics, synthetic chemicals), composite agents (a blend of inorganic and organic materials), and natural agents (e.g., plant extracts, essential oils). These agents work by disrupting the cell structure or metabolism of microorganisms, preventing their reproduction or causing their death.
An antimicrobial is any substance that kills or inhibits the growth of microorganisms by suppressing microorganism reproduction. Microorganisms are unicellular or cell-cluster microscopic organisms, including eukaryotes such as fungi and protists, and prokaryotes such as bacteria and certain algae.
-
Antibacterial Agent Release
Antibacterial molecules are slowly released from the masterbatch to the product surface, forming a lasting antibacterial barrier. The release rate is precisely controlled to ensure long-term effectiveness without depleting too quickly. -
Bacteria Contact
When bacteria come into contact with the product surface, the antibacterial molecules bind to the bacterial cell wall or membrane, damaging its structural integrity and blocking the bacteria’s life processes. -
Metabolic Interference
Once inside the bacteria, the antibacterial agent interferes with the bacterial enzyme system and metabolic pathways. It inhibits the synthesis of DNA, RNA, and proteins, ultimately causing the bacteria to die or become unable to reproduce.
