Recently, many key technologies such as sealing, compounding and anti-adhesion in the asphalt soft packaging production process were successfully developed by Dalian Xinke Packaging Materials Co., Ltd. This technology makes the flexible packaging bag degradable, filling a gap in China's packaging products. As a result, the State Environmental Protection Administration has named the country's key environmental protection practical technologies.
The traditional asphalt packaging uses iron drums as a packaging material, and removes the asphalt by heating and the like. As this type of packaging will leave 10 to 15% of bitumen, it will cause great waste, and the asphalt-filled drums and spilled asphalt will directly pollute the environment. The potential danger during operation is even more worrying. In order to solve this problem, in 1995, the company was commissioned by China National Petrochemical Corporation to research and develop a new generation of environmentally friendly asphalt packaging suitable for the Chinese market. After more than 100 filling and transportation feedbacks and tracking feedbacks in 6 years, the company has developed and gradually improved, and finally developed a bitumen flexible packaging product suitable for the Chinese market.
The environment-friendly asphalt packaging bag overcomes the disadvantages of heavy weight and large volume of the iron drum packaging, which is not net-melting, wasteful, and high in cost. The packaging material using the technology can be recycled, and has high-temperature filling and easy peeling. The unique advantages of non-stick bags, moisture proofing, anti-adhesion, anti-aging and other unique features have won unanimous praise from the relevant state departments.
