A Taiwanese businessman is confident of starting a revolution in the food and drink containers industry with a greener alternative to styrofoam containers providing he receives the necessary support from the government and is able to cut costs.
Lin Yi-an (林一安) said styrofoam (polystyrene plastic) containers are convenient because they are light and disposable.
However, he added that styrofoam products are not microwavable and can generate carcinogenic residues when treated with acid or alkali solutions.
As chairman of Changhua County-based Reach Plastic Industrial Co, Lin worked for eight years on developing a non-toxic extruded polypropylene (PP) foam as an alternative to styrofoam packaging.
Because styrofoam is called bao-li-lung (保麗龍) in Mandarin, Lin named the new PP-foam product Taiwan-lung (台灣龍), which means Taiwanese dragon.
Lin said that when people buy coffee at convenience stores, the paper cups are lined with a plastic film to prevent leakage and also have a paper liner for insulation.
However, he said cups made using PP foam are naturally well-insulated and can be filled with hot liquid and held comfortably.
“The product has good insulation properties and can keep contents at the desired temperature,” Lin said.
“Products made from PP foam can withstand temperatures of up to 125oC, are microwavable and can be used in steam cookers,” he said.
“The material is non-toxic, and resistant to acids and alkalis,” Lin added.
Also, because the material is regarded as non-toxic, it is completely recyclable and reusable.
For its extrusion foaming agent, an inorganic gas is used.
Due to these environmentally friendly features, PP foam food containers won the gold prize at the 2009 International Exhibition of Inventions of Geneva, Switzerland.
It was also awarded a prize at an invention competition in Russia, Lin said.
Lin begain his career working in the manufacture of machines for styrofoam production and so is well aware of the material’s toxicity.
He then founded Reach Plastic Industrial Co, which concentrates on research and development (R&D) of food containers.
Because the company is engaged in developing new products, Lin had no point of reference for his research, he said.
Over eight years, the firm invested about NT$10 million (US$340,000) a year in R&D, he added.
In 2007, the company developed the world’s first non-toxic food container made of PP foam.
It commercialized the product in 2011.
However, despite early successes, Lin has encountered a problem: Due to the unique nature of the product, its ingredients must be imported from Austria, making costs NT$0.2 higher per unit compared with styrofoam products.
This has meant that despite buyers often rating the product highly and being impressed with its environmentally-friendly credentials, sales have been lackluster.
The Taiwan Railway Administration had considered using the firm’s PP-foam containers for its lunch boxes, but decided against it because they were more expensive than styrofoam products.
However, Lin remains upbeat about his product and said: “I believe it will not be another eight years of struggle. We will see a major breakthrough this year.”
There are good reasons for his optimism.
The Greater Tainan Government has recently set low-carbon targets and announced that it will ban all polystyrene styrofoam products from July.
