Leading Maintenance PP SB Nonwoven Fabric with Bacterial Inhibition and Ethylene Gas Absorption
(Freshness maintenance function PP SB nonwoven fabric)
01.
Functional masterbatch material incorporating functional inorganic particles with far-infrared emission properties into polymer resin.
02.
Demonstrating freshness and antibacterial effects through far-infrared emission characteristics.
Key Features
Freshness preservation
Prolonged freshness of food items such as vegetables and fruits
Non-toxic
Non-toxic plastic product containing harmless inorganic particles.
Far-infrared emission
Far-infrared (FIR) emission upon contact with food.
Optimal moisture retention
Moisture regulation/aging delay by far-infrared (FIR).
Mechanism for Food Freshness
Maintaining freshness by inhibiting bacteria and absorbing ethylene gas.
Maintaining an appropriate environment through the thermal properties and gas adsorption characteristics at a specific wavelength.
Strong penetration and resonance phenomena of far-infrared activating food cells 2,000 times per minute.
Increased resistance to external factors like bacteria or viruses for prolonged freshness.
