Nano Antimicrobial Agent Application in Food Packaging
With the continuous upgrading of global hygiene and safety standards, consumers and manufacturers have higher requirements for the safety, freshness retention and hygienic performance of food packaging and daily chemical containers. Traditional packaging materials and plastic products are prone to bacterial reproduction, mildew growth and odor breeding during production, transportation, storage and daily use, which greatly shortens product shelf life and brings hidden health risks.
Our nano inorganic antimicrobial agents and finished antimicrobial masterbatch are specially developed for food-grade packaging and daily plastic products. Featuring high safety, high temperature resistance, non-precipitation and long-lasting antibacterial properties, they can be perfectly added into PP, PE, PET, PS and other substrate materials, achieving one-time modification and lifelong antibacterial protection.
Core Advantages for Food Packaging
1. Food-Grade Safety, Zero Harmful Residues
Different from traditional organic antibacterial agents with poor stability and easy precipitation, our nano antibacterial ingredients are sintered and compounded by inorganic mineral materials. The active antibacterial ions are stably locked in the material lattice, with no dissolution, no precipitation and no chemical residue. It fully complies with FDA, RoHS, REACH and food contact safety standards, and is safe for direct contact with food, skin and cosmetics
2. Broad-Spectrum Bacteriostasis & Effective Freshness Preservation
It has an inhibition rate of over 99.9% against common harmful bacteria and molds such as E. coli, Staphylococcus aureus, Candida albicans and mildew. It can effectively inhibit bacterial cross-breeding on the surface of packaging materials, slow down food oxidation and spoilage, and significantly extend the shelf life of fresh food, snacks and daily chemical products.
3. High Temperature Resistance & Process Compatibility
Nano inorganic antibacterial components can withstand 220°C–280°C high-temperature processing. They will not decompose or fail during injection molding, blow molding, film blowing and extrusion production of food packaging and daily chemical plastics. They are 100% compatible with existing production lines, without changing original production processes and formulas.
4. Long-Lasting Efficacy & Washable Durability
The antibacterial function is integrated with the plastic substrate molecularly, not attached to the surface. It will not fail due to packaging friction, surface cleaning, water washing and long-term storage. The antibacterial and anti-mold effect covers the whole service cycle of the product, avoiding the problem of short-term failure of surface spraying antibacterial treatment.
5. No Impact on Material Appearance & Performance
The nano-scale ultrafine powder has good dispersion, does not produce agglomeration, and will not affect the transparency, gloss, toughness and tensile properties of packaging films and plastic containers. It solves the pain points of traditional antibacterial additives such as yellowing, fogging and brittle materials.
