Application

Our oxygen absorber sachet is commonly used in the packaging of food, medicine, medical equipment, electronic products and other oxygen-sensitive products. There are many common use scenarios. For example, it is used to keep baked goods, dried fruits, nuts, coffee, meat products and other foods fresh, to prevent oxidation and deterioration. It is used in the packaging of medicines and diagnostic reagents, to ensure the stability of drug efficacy. It is used in the packaging of industrial products, to prevent metal oxidation or deliquescence. These absorber bags effectively extend the shelf life and service life of products by reducing the oxygen concentration in the package. Therefore, they can be widely used in various industries that need to protect product quality.

Safety

These oxygen absorber sachets are generally safe to use when handled properly. They are non-toxic and made from food-grade materials, ensuring safety for food preservation purposes. However, they are not meant for consumption and should be kept out of reach of children and pets. If accidentally ingested, seek medical advice. Proper usage following instructions ensures both safety and effectiveness in extending the shelf life of food products.

Storage

These oxygen absorber sachets should be stored in a cool, dry, and airtight environment to maintain their effectiveness. Keep them sealed in their original packaging until use to prevent premature exposure to air, moisture, or contaminants. Avoid high temperatures and direct sunlight, which could compromise their functionality. Once opened, unused sachets should be stored in an airtight container or vacuum-sealed to preserve their performance.
