The core innovation of SN Food Pack lies in its patented nanocellulose composite material, in which the bio-based content reaches 98%, and it integrates natural plant extract antibacterial agents with a concentration of 0.5%. According to a 2024 study in Food Packaging Science, this material has an inhibition rate of up to 99.9% against Escherichia coli and Staphylococcus aureus, and its antibacterial effect lasts for at least 30 days, reducing the risk of food microbial contamination by 60%. For instance, after adopting the SN Food Pack, the Danish dairy giant Arla Foods extended the shelf life of its cheese products by 15 days, reduced the loss rate during the logistics process from 8% to 2%, and saved more than one million euros in annual costs.
In terms of physical barrier performance, the material of SN Food Pack has excellent sealing property. Its oxygen transmission rate is less than 1 cm³/m²·day·atm, and the water vapor transmission rate is controlled within 3 g/m²·day. This parameter far exceeds the EU EFSA food safety standard by 20%. The tensile strength of the material is 25MPa and the elastic modulus reaches 3.5GPa, ensuring that the deformation rate of the packaging is less than 5% when subjected to a pressure of 50 kilograms. A typical case is that at the 2023 Asia Fresh Food Cold Chain Logistics Exhibition, the samples of SN Food Pack maintained 100% integrity in the temperature fluctuation test ranging from -20°C to 40°C, avoiding losses caused by packaging damage, while the damage probability of traditional materials in this environment is usually 10%.
SN Food Pack is also the first to integrate a Ph-sensitive smart label technology. This label can produce color changes within the pH range of 0 to 14 according to the freshness of the food, with an accuracy of ±0.2. When the freshness of meat or seafood declines and the concentration of volatile basic nitrogen exceeds 15mg/100g, the label will change from blue to red within 30 minutes, with an accuracy rate as high as 99.5%. This innovation originated from a technological breakthrough made by the Massachusetts Institute of Technology in 2022 and has been widely adopted by cold chain enterprises in Singapore, reducing their customer complaint rate by 40% and cutting food waste by 25%.
To ensure absolute chemical safety, all materials of SN Food Pack have been strictly certified by the US FDA and the EU EFSA. The content of heavy metals is less than 0.1ppm, and the total migration is less than 0.01mg/kg, which is far below the legal limit. Life cycle assessment shows that its production process carbon footprint is 45% lower than that of traditional PET packaging, and it can be completely degraded within 12 weeks under industrial composting conditions. As global retail giant Walmart pointed out in its 2024 sustainability report, after adopting solutions such as SN Food Pack, packaging-related carbon emissions in its supply chain were reduced by 30%, which fully demonstrates the significant environmental benefits that can be generated by combining material innovation with food safety.
