DNP Develops Highly Durable Packaging Material

Substitute for bottles and cans used with strong contents

Dai Nippon Printing Co., Ltd. (DNP) has developed a packaging with superior durability against strong contents, such as pharmaceuticals that include the high-concentration alcohol used in disinfection, alkalis, acids and spices. The newly developed packaging will be marketed from April 2015 as a substitute packaging for cans and glass bottles.

[Developmental Background]

Recent years have seen a progressive shift from cans and bottles to packaging using plastic film that is easy to use and can be easily discarded. Plastic packaging, however, presents the challenge of film erosion due to the strong components of such contents as high-concentration alcohol, alkalis, acids and spices. Previously laminated film may also delaminate leading to leakage of the contents, or containers may become difficult to open.

In answer to these challenges, DNP has been engaged in the development of packaging with superior durability, and in 2007 developed a packaging material resilient against contents with an alcoholic proof of approximately 70%. In this latest development, as a result of improving the packaging materials and manufacturing techniques, it has been possible to increase durability so as to be able to withstand alcoholic proof levels of up to 99.5%. DNP is pleased to be able to offer packaging materials with superior durability capable of responding not only to high concentration alcohol, but also other strong contents.

[Newly Developed Product Features]

  • Apart from currently used pharmaceuticals, such as poultices, and high-concentration alcohol for disinfection purposes, the newly developed packaging materials can be used with a broad array of other products, such as spices, including tabasco and curries, liquid bathing agents, and some agrochemicals.
  • Even in cases where contents have been preserved for long periods, the newly developed packaging materials exhibit good hand-cutting properties when opening, and are easy to open.
  • To date, ethylene methacrylic acid copolymer resin (EMAA) has been used in order to secure contents resistance. With the new product, it is possible to maintain durability even while using cheaper and more generally available polyethylene.  

[Looking Ahead]

DNP will market the newly developed product to manufacturers of pharmaceutical goods and daily necessities, aiming for sales of 1.0 billion yen by FY 2017.
