DNP Develops Packaging Using Odor-Absorption Film
Superior absorption properties against aldehyde and ketone odors
Dai Nippon Printing Co., Ltd. (DNP) has developed packaging material capable of absorbing aldehyde and ketone odors that are outgasses with unpleasant odors generated by various organic compounds. Mass production of packaging materials targeting pharmaceuticals, medical devices, industrial equipment and chemical agents will commence in September 2015.
Pharmaceuticals that include organic compounds, such as aldehydes and ketones release outgas in line with the passage of time following manufacturing. And as a result, the odors trapped in the packaging can present users with an unpleasant sensation when opening to access medication. Also, when medical devices, such as scalpels, or scrubs, are placed in a bag and sterilized with e-beams, for example, there are cases of the irradiated bag generating odor components.
DNP has yet again risen to the challenge, and has developed packaging material that absorb unpleasant odors by impregnating film with material capable of absorbing specific odors.
[New Product Features]
- The newly developed product is packaging material that impregnates film with material capable of absorbing specific odors. Tests showed that 24 hours after pharmaceuticals are packaged, almost 100% of the odor components that form outgasses were absorbed into the film, resulting in an odorless state. (Please refer to the accompanying graph). As a result, it is possible to reduce unpleasant sensations from odors when opening the packaging.
- Nor are the absorbed odor components re-released, meaning it is possible to obtain an effect on an ongoing basis.
- And as there is no need to insert a deodorant sachet into the packaging, there are no fears of users accidentally swallowing the sachet.
- Apart from such unpleasant odors and aldehydes and ketones, the newly developed packaging is also effective against sterilization odors and resin decomposition odors.
DNP will market this new product as packaging mainly for pharmaceuticals, medical devices, industrial equipment and chemical agents aiming for sales of 500 million yen by FY 2019.
