DNP Develops Packaging Using Film with Strong Low-Absorption Qualities against Pharmaceuticals and Cosmetics
Dai Nippon Printing Co., Ltd. (DNP) has developed packaging materials based on a film that suppresses the absorption of the active components in pharmaceuticals along with the fragrant components of cosmetics. In doing so, the Company has applied the film deposition technology and laminating technology developed through long involvement with food packaging. And in addition to suppressing the absorption of such components into the film, has also successfully raised sealing strength by a multiple of two to three compared with currently used polyacrylonitrile (PAN) film. As a result, it is now possible to use this film in a variety of formats and for diverse uses, including pharmaceuticals, daily necessities and foods. From September 2015, DNP will launch sales of a total of three types of film; a polyester film, and two types of polyolefin film.
To date, PAN film has mainly been used with the objective of protecting the active components in the contents of pharmaceutical and cosmetic sample sachets. However, this type of film has extremely weak sealing strength, which has restricted packaging format. Given that PAN film can also be difficult to obtain, it is perhaps no surprise that this weakness has fuelled increased needs for a substitute. The absorption of the fragrant component of strongly flavored and highly palatable foods and beverages has also become a challenge, leading to increased calls for the use of low-absorbent film. In answer to these needs, DNP has developed packaging material with a high sealing strength that can be used in a variety of formats and for diverse uses, while maintaining similar low absorption features to packaging materials that make use of PAN film.
[Features of Low Absorption Film]
Polyester Film: The newly developed film boasts performance equivalent to that of currently used PAN film regarding component retention with pharmaceuticals and cosmetics. DNP offers packaging using this film as a substitute for PAN film for such uses as those with sample sachets. As the newly developed film boasts approximately twice the seal strength of PAN film, it can be used with a variety of contents.
Polyolefin film: Apart from suppressing absorption of active components, polyolefin film also retains the fragrance of comfort foods. DNP offers two types of packaging; as film sold in combination with paper beverage containers, and as a stand-up pouch for daily necessities. The sealing strength of these two types of film is more than three times that of PAN film, and is similar to that of existing paper-made containers for liquid and stand-up pouches. DNP is promoting the switch to packaging using this new film.
DNP will market the newly developed product to manufacturers of pharmaceuticals, cosmetic goods and beverages, aiming for sales of 1.0 billion yen in FY 2017.
