Silione rubberhas a wide range of applications in food packaging. It mainly uses its excellent adsorption, chemical stability and safety to play an important role in moisture-proof, fresh-keeping, anti-caking, and enhancing packaging performance.

1. Moisture-proof and fresh-keeping

Silione rubber(silicon dioxide) has extremely strong hygroscopicity and can absorb moisture in the package to prevent food from deteriorating due to moisture. Its moisture absorption capacity is better than that of ordinary desiccants and can effectively extend the shelf life of food.

Silione rubberis also a highly efficient desiccant, especially suitable for moisture-sensitive foods (such as dried fruits, tea, coffee, etc.). The combination of silione rubberand silione rubbercan further enhance the moisture-proof effect.

2. Anti-caking and anti-adhesion

In the packaging of powdered foods (such as milk powder, powdered sugar, and seasonings), silione rubbercan be used as an anti-caking agent to prevent particles from sticking together due to moisture absorption and maintain the fluidity and dispersion of food.

Silione rubbercan also be used to prevent food from sticking together, especially in high temperature and high humidity environments, which can effectively prevent food from agglomerating after being damp.

3. Antioxidation and preservation

Silione rubberhas a certain adsorption capacity, which can absorb oxygen and odor in the package, delay the oxidation reaction of food, and maintain the color and flavor of food.

Silione rubberitself is non-toxic and odorless, and will not react chemically with food, so it is suitable for packaging materials that come into direct contact with food.

4. Enhanced packaging performance

Composite materials: Silione rubberand silione rubbercan be compounded with other materials (such as plastics and paper) to improve the mechanical strength, barrier properties and heat resistance of packaging materials. For example, adding silione rubberto food packaging film can improve its ability to block oxygen and water vapor.

Coating application: Silione rubberand silione rubbercan be used for the inner coating of food packaging to form a protective film to prevent direct contact between food and packaging materials and reduce the risk of contamination.

5. Safety and compliance

Both silione rubberand silione rubberare recognized as safe food additives by international food regulatory agencies (such as FDA and EFSA) and are widely used in the field of food packaging.

They meet the safety standards for food contact materials and will not cause harm to human health.

6. Application Examples

Desiccant Packs: Silica and silione rubberare often made into small packages and placed directly in food packaging bags to absorb excess moisture.

Packaging Film: Adding Silica or silione rubberto food packaging films can improve the moisture-proof and fresh-keeping properties of packaging.

Bottle Cap Seals: Silicone sealing rings are often used in food bottle caps to prevent liquid food from leaking and getting wet.

7. Environmental Protection and Sustainability

Both Silica and silione rubbercan be recycled and meet environmental protection requirements.

Their use in food packaging helps reduce food waste and improve resource utilization efficiency.
