Food packaging
C-POLAR and NanoFlashing™ questions, with the company’s answers and the sources they come from.
Last reviewed: .
Does a shelf-life claim apply before opening, after opening or both?
The company makes no shelf-life claim for any food.
NanoFlashing™ Food Packaging changes the role of the package itself. It has a permanent positive polarity, a fixed positive charge. NanoFlashing™ attracts negatively charged particles through electrostatic attraction. When a captured pollutant has a fragile structure, NanoFlashing™ destroys it on contact through a physical mechanism. Date marking, storage conditions and the instructions printed on a package are set by the food producer and the maker of the package. The one food comparison the company publishes is the Strawberry Test: three strawberries held at 26°C for thirteen days, one stored in a glass jar, one wrapped in polyester, and one wrapped in NanoFlashing™ Food Packaging. The film on the page labels the strawberry in a glass jar “Expired on Day 2”, the one in polyester “Expired on Day 3”, and the one wrapped in NanoFlashing™ Food Packaging “Expired on Day 12”. The Terms of Use state: “Images and descriptions may show concepts or prototypes. They are not specifications, instructions, validation reports, recommendations, warranties, offers, promises, or commitments.”

All questionsCan treated packaging replace any part of the food's cold-chain requirement?
The package does not change what the food needs.
NanoFlashing™ Food Packaging changes the role of the package itself. It has a permanent positive polarity, a fixed positive charge. NanoFlashing™ attracts negatively charged particles through electrostatic attraction. When a captured pollutant has a fragile structure, NanoFlashing™ destroys it on contact through a physical mechanism. The company’s own food page cites the FDA for the point that refrigeration does not kill most bacteria and that Listeria can multiply near 0°C. It also states: “Cardiff Metropolitan University monitored 43 household refrigerators for about a week; none stayed at 5°C or below throughout.” Date marking, storage conditions and the instructions printed on a package are set by the food producer and the maker of the package. The Terms of Use state that the evidence, specifications, instructions and warnings to rely on are those specific to the actual finished product and use.

All questionsWould a change in smell be reliable evidence that packaged food is safe?
Smell is not a test.
The company’s food page sets it out: conventional gas-filled food packaging slows the bacteria that make food spoil, so the package can suppress the bacteria that warn us food is spoiling while a dangerous pathogen keeps growing unseen. The page’s own words for this are “Nothing warns you.” The page cites a study to make the point: “At Cornell, scientists added Listeria to minced raw chicken in commercial-style gas packaging. After 3 weeks under refrigeration, Listeria had multiplied nearly 1 million times; the gas suppressed ordinary spoilage bacteria but did not stop Listeria.” NanoFlashing™ Food Packaging changes the role of the package itself. It has a permanent positive polarity, a fixed positive charge. NanoFlashing™ attracts negatively charged particles through electrostatic attraction. When a captured pollutant has a fragile structure, NanoFlashing™ destroys it on contact through a physical mechanism.

All questionsDoes a packaging benefit apply to the food itself or only to the package surface?
What the company states is about the package.
NanoFlashing™ Food Packaging changes the role of the package itself. It has a permanent positive polarity, a fixed positive charge. NanoFlashing™ attracts negatively charged particles through electrostatic attraction. When a captured pollutant has a fragile structure, NanoFlashing™ destroys it on contact through a physical mechanism. A charge is a physical property. It is not a substance or a mixture of substances. As of the Effective Date, the Water, Textiles, Food packaging, and Medical devices chapters describe Research Applications. They do not describe finished products currently available from C-POLAR for those uses.

All questionsDoes the evidence distinguish food quality from food safety?
The company’s pathogen evidence is about what the material does to viruses, bacteria and fungal spores; the one food comparison it publishes is the Strawberry Test, and it publishes no food-safety assessment.
The Validation page names the organisms tested, the conditions tested and the institutions that tested them. A reported result describes only what the identified test found. The company’s own food page makes the point that a package can suppress the bacteria that warn us food is spoiling, while a dangerous pathogen keeps growing unseen. As of the Effective Date, the Water, Textiles, Food packaging, and Medical devices chapters describe Research Applications. They do not describe finished products currently available from C-POLAR for those uses. A report covers the article, the method and the conditions named in it.
