Toppan Printing develops a laminated packaging

2013/5/8      view:
This product is the first laminated packaging material in Japan to use biomass PE with a thickness of less than 40μm, which has been achieved through the use of laminating technology that differs from conventional techniques. The product uses plant-derived raw materials but maintains performance equivalent to conventional petroleum-based products in terms of properties such as seal strength and laminating strength.

Biomass plastic is a renewable resource that uses plant-derived raw materials and can be used sustainably. It contributes to the establishment of a sustainable society because it enables a reduction in the volume of oil and other fossil resources used. It is receiving attention as an environmentally friendly material because CO2 in the atmosphere is absorbed when the plants are growing, and because the CO2 absorbed during plant growth is considered to offset any CO2 released if the product is incinerated, meaning that it is possible to reduce CO2 emissions when compared with petroleum-based products.
In 1991, Toppan Printing began efforts to develop and commercialize packaging materials using biomass plastics as part of its initiatives to mitigate global warming and reduce the use of oil. In 2011, the company was the first in Japan to develop a laminated packaging material using biomass PE with a thickness of more than 100μm. This has been commercialized as a flexible packaging material for liquids and is used in applications such as refill standing pouches for toiletries. Using a laminating technology that differs from conventional ones, Toppan Printing has developed a laminated packaging material that uses biomass PE with a thickness of less than 40μm. It will be possible to expand the use of this material as flexible packaging in wide ranging fields including food and medicine.

Previous laminated packaging materials using biomass PE have been manufactured using dry lamination where the films are laminated using an adhesive.
With this product, it has been possible to produce biomass PE with a thickness of less than 40μm by establishing a biomass PE processing technology where extrusion laminating technology is used to produce a thin coat of PE that has been melted to one side of a substrate film.

With the establishment of the biomass PE extrusion processing technology, Toppan Printing has been successful in developing flexible packaging material that has a biomass ratio of at least around 10%. 

Toppan Printing will continue research and development on this product and aim to begin mass production in the spring of 2013. The company is aiming for sales of 3 billion yen in fiscal 2015 for this product and related orders.
