5 Ways Flexible Packaging Can Extend Product Shelf Life

Flexible packaging has become the preferred packaging solution for many industries due to its light, flexible, and efficient characteristics. However, how to use flexible packaging to effectively extend the shelf life of products, reduce losses, and ensure consumers get the best experience is the focus of brand attention. So, how does flexible packaging extend the shelf life of products? The following introduces 5 common key methods to provide you with practical knowledge and inspiration.

Use materials with excellent moisture-proof, air-barrier, light-proof, and sealing properties

Flexible packaging materials such as aluminum foil and plastic film have moisture-proof, air-barrier, light-proof, and sealing properties, which can isolate air, moisture, and light from the damage of drugs. These materials can ensure that the quality of drugs remains stable in the packaging, thereby extending their shelf life.

Use multi-layer composite films

The combination of multi-layer composite films such as LDPE, PP, PET, and other materials further enhances the barrier properties and physical strength of the packaging. This structure can better protect the product from deterioration caused by moisture, oxidation, or light.

Optimize sealing technology

Efficient sealing technology is one of the keys to ensuring that flexible packaging can extend the shelf life. Heat sealing, cold sealing, or other high-performance sealing technologies can ensure the tightness of the packaging bag and prevent the entry of external contaminants. These technologies can effectively prevent the product from contact with oxygen in the air, avoid moisture loss, and reduce the risk of corruption and deterioration.

Use vacuum packaging

Vacuum packaging is the process of removing air from the packaging bag to reduce the contact of oxygen with the product and prevent bacterial growth and mold. Vacuum packaging is particularly important for foods that need to maintain freshness, such as meat, dairy products, nuts, etc.

Use aluminum foil gaskets and desiccants

Placing aluminum foil gaskets and desiccants in the package can absorb moisture in the package and ensure a dry environment inside the package. These measures work together to effectively prevent the deterioration of drugs caused by moisture, oxidation, or light.

The development of flexible packaging technology enables companies to better deal with product shelf life issues. Brand merchants can choose the most appropriate packaging method based on product type and market demand, thereby extending the shelf life of the product and improving the consumer experience.
