Antimicrobial Plastic Testing

Plastic testing is done to ensure the effectiveness of antibacterial finishes used in product formulation.

The majority of the items we use on a daily basis are made up of plastic. Owing to its inexpensive, unbreakable, and durable nature, plastic has become an important and ubiquitous part of our lives. However, there are many scientific evidence showing that plastic surfaces and non-porous materials allow pathogenic bacteria to thrive and spread infection.

Antimicrobial plastics appear as an emerging solution to combat microbial threats to mankind, primarily in patient environments and public places. Basically, antimicrobial plastics comprise integrated and active agents that either eliminate or hinder the growth of infection-causing microorganisms.

Antimicrobial testing is an important step after manufacturing of antimicrobial plastic products to ascertain their efficacy and strength against harmful microorganisms.

Antimicrobial Plastics Test Methods

There are many scientific organizations worldwide that publish test methods to validate the efficacy of antimicrobial-treated plastics.

  • International Organization for Standardization (ISO)
  • American Association of Textile Chemists and Colorists (AATCC)
  • American Society for Testing and Materials (ASTM)
  • Japanese Industrial Standard (JIS) 

At Microbe Investigations, we perform following efficacy test for antimicrobial treated plastics

  • JIS Z 2801Measurement of Antibacterial Activity on Plastics Surfaces (Plastics)
  • ISO 22196 : 2007Measurement of antibacterial activity on plastics surfaces
  • ISO 21702 : 2019Standard for measuring  antiviral activity on plastics and other non-porous surfaces
  • ISO 846 : 2019Evaluation of the action of microorganisms on plastics
  • ASTM E2180 : 2018Standard for evaluating the efficacy of incorporated antimicrobial agents in polymeric or hydrophobic materials
  • ASTM G21 : 1996Standard  for determining the antifungal resistance of  synthetic polymer materials
  • ASTM G29 : 1996Standard for determiation  of Algal resistance of plastic films

Examples of the Plastic Products Tested at MIS

  • Coating materials
  • Ceramic
  • Natural and artificial leather
  • Rubber
  • Vinyl siding
  • Roofing membranes
  • Surgical gloves
  • Medical devices
  • Storage containers
  • Antimicrobial phone covers

Advantages of Antimicrobial Testing on Plastic Products

  • Reduce the burden of microbial infections

Any reusable plastic products may harbor harmful bacteria if it isn’t sterilized or cleaned properly. This eventually leads to the transmission of microbial infection and potential health hazards. Such type of microbial contamination is usually high in dental and hospital facilities. Luckily, the susceptibility to such infections can be easily avoided with the use of antimicrobial plastic materials.

  • Increases product durability

Several bacteria have been identified that can degrade plastic materials. Antimicrobial additives incorporated on plastic materials work to mitigate the growth of such microbes, hence expanding the functional life of plastics. 

  • Protects Against Staining & Bad Odors

It is usually noted that plastic containers tend to retain a yellow color and unpleasant odors after frequent and continuous usage. However, such issues do not happen with antimicrobial plastic materials due to the presence of antimicrobial additives. Additionally, antimicrobial agents also help to maintain the aesthetic appeal of the products.

  • Prevents biofilm formation

Microorganisms that adhere on the hard surface of plastic material begin to reproduce and secrete a slimy, glue-like substance called biofilm. Along with eradicating harmful pathogens, antimicrobial plastics are also quite useful in preventing the formation of biofilm.
