PE material how to choose antibacterial agents

Antibacterial plastic is a kind of plastic that inhibits or kills bacteria, molds, alcohol mother bacteria, algae and even viruses in the use environment, and keeps itself clean by inhibiting the reproduction of microorganisms. At present, antibacterial plastics are mainly obtained by adding a small amount of antimicrobial agents to common plastics.

In the use of antibacterial plastics, first of all, the necessary requirements for the physical, chemical, mechanical and other properties of the plastic as a basic material should be met, and at the same time, the requirements for the special function of antibacterial and the resulting additional factors should be considered. Therefore, antibacterial plastics should have good mechanical strength appearance, chemical stability, good machinability. In terms of antibacterial, antibacterial plastics should be able to adapt to the use environment, and should have high efficiency, broad spectrum, long-term antibacterial properties. Because the antibacterial plastic contains a small amount of antibacterial agent, so the requirements of the antibacterial agent used to achieve the specified health safety, and make the ultimate antibacterial plastic products to achieve non-toxic, no smell, harmless to the environment.

Polyethylene (polyethylene, PE for short) is a thermoplastic resin made by polymerization of ethylene. Polyethylene is divided into HDPE, LDPE and LLDPE according to the polymerization method, molecular weight and chain structure. It is mainly used for the manufacture of film, packaging materials, containers, pipes, monofilaments, wires and cables, daily necessities, etc

PE related to antibacterial, mostly: film, packaging materials, containers, daily necessities.

This requirement has the following characteristics:

A: production performance: in the production, can not appear mucous membrane and precipitation problems, can not affect the tensile and other mechanical performance.

Two: color requirements: PE products in the later use, the need for color stability, to maintain a stable product appearance!

3. Safety: PE products are mostly in direct contact with people, which need to meet RoHS and REACH. In certain circumstances, must meet the GB9685 (through the GB4806 test), FDA precipitation test, can not bring secondary pollution!

So how should we choose antimicrobial agents? Evenclean recommends inorganic antimicrobial agent, which can well meet the food contact level, low addition ratio (0.3-0.5%), temperature resistance up to 400-500℃ or more, color stability, no precipitation, odorless, transparent. Such as our JP-904 (silver antibacterial agent) JP-928 (zinc antibacterial agent). Eliminate safety, odor, color, and precipitation problems associated with organic antimicrobials. Can be stable through GB/T 31402, GB/T 21551, ISO 22196, JIS Z 2801 GB/T 36391 and so on.
