BacStop™ Microbial Control film

BacStop Microbial Control Film

Enhance Shelf Life and Inhibit Bacterial Growth

Polymer Packaging introduces a new low-cost microbial control flexible packaging film converted into bags, sheeting, rolls and pouches. Our microbial control film inhibits the growth of harmful microorganisms such as bacteria, fungi and molds. Initial testing has shown that BacStop™ inhibits growth of bacteria by 99.9%.

What is the Shelf Life of BacStop™?

BacStop is easily blended into the film so it does not wear off or leach out. We have conducted shelf-life testing with various food/drink products that does not show any microbial growth for 1-2 years.

Safe and Effective

BacStop uses safe and effective copper sulfate as the active microbial control ingredient. It has excellent dispersion properties due to its patented electrostatic carrier technology. BacStop is ideal for food processors and does not have ANY adverse effects on the product.

BacStop™ Testing

BacStop is tested to ISO 22196:2011 standards against common organism such as E. Coli, Salmonella, Listeria, Staphylococcus Intermedium, Streptococcus Mutans and Staphylococcus Aureus. Our independently tested laboratory results are available on request. Contact Polymer Packaging for BacStop compatibility testing with your specific product.
