Preservation vs. Display Strategy
Choosing between transparent and metallised flexible barrier films involves balancing the consumer desire to see the product with the chemical need to shield ingredients from light and air.
When to Choose Transparent Packaging
Consumers trust what they can see. If your product has an attractive visual appearance—such as colorful candies, whole almonds, yellow lentils, or bath salts—transparent pouches let the product sell itself on the shelf. However, products high in polyunsaturated fats can degrade under supermarket fluorescent lighting.
When to Choose Metallised Packaging
Ground spices, roasted nuts, extruded snacks, and namkeen contain fats and volatile aroma compounds susceptible to photo-oxidation. Metallised films reflect light away, maintaining freshness, aroma, and crispness over extended shelf lives.
The Hybrid Advantage
Pactrum hybrid pouches provide an optimal compromise: a transparent front panel gives buyers full view of the product, while the metallised back panel reflects ambient light through the pouch and provides a gleaming metallic frame for the contents.
