How VAMSA currently describes Fresh Keeper
The current VAMSA Agri website states that a patented Silver Nano Technology converts ethylene gas into ethylene oxide and that the breathable liner allows the converted gas to leave the package.
Because this is a specific chemical, performance and safety claim, the new website should not publish it as an established fact until the company provides:
- patent number and granted territories
- mechanism/test methodology
- concentration/exposure data
- food-contact and migration evidence
- worker/consumer safety assessment
- applicable standards and independent laboratory reports
What the customer page should explain after validation
- What happens to ethylene in the package.
- Whether the technology absorbs, adsorbs, oxidizes or otherwise transforms ethylene.
- The operating conditions under which the mechanism was tested.
- Produce types and packaging formats tested.
- Any limits on temperature, humidity, ventilation or storage duration.
- Safety and regulatory documentation relevant to the target market.
Compare technologies carefully
Avoid generic claims that one ethylene-management technology is always superior to another. Use application-specific evidence and define the test conditions.
