Non-Interactive NIf™

Packaging films have been around to ensure the ingredients inside stay active. Conventional film can absorb some of the content’s active ingredients into the packaging film over time. When consumers use this product, the active ingredients begin to deteriorate, reducing the expected effect of the product. This is why NIf™ (Non-Interactive film) are so important.

Many sachets are handed out daily in the cosmetics and personal care industry to promote the brand’s products. Most of these sachets are wrapped in Polyethylene (PE) or Polypropylene (PP) packaging, which could absorb active ingredients into the product. It is a huge possibility that the sample consumers are trying needs to reflect the product. With more than 122 billion single-use sample sachets created annually, imagine how many consumers are misled.



Vitamin D Tragedy

A brand owner had to recall several of their products due to decreases of vitamin D concentration. They were using PE film and the research proved that the vitamin D in their products were adsorbed by their packaging layer.



Using our NIf™, your product’s active ingredients will stay in top shape. The non-interactive film prevents interactions between the packaging and the contents inside. It has excellent packaging material for sensitive products.




  • Non-Interactive – Minimizes the sorption of active ingredients transferred to the packaging compared to the PE sealant (Active ingredients: nutrients, fragrances, medicinal ingredients, etc.).
  • Low-Leaching – Blocks movement of leachable between layers. The NIf™ can be used as the innermost or intermediate layer.
  • Prevents the degradation of packaging because of the contents inside.

NIf™ series has several film structures for different applications. Among the NIf™ series, NIf™-β is suitable for cosmetics and personal care products. Packaging materials are critical, especially for cosmetics product test samples and facial masks in flexible packages. These products have small volumes of active ingredients, and any change in product potency significantly affects customer experience.

Its use ranges from primary packaging for liquid or powder/granule oral drugs to transdermal patches. The technology is also applied to the MediTect™ IV bag for ready-to-administer injectable solutions.
