摘要： Amorphous propylene-ethylene copolymers are described herein that can include high amounts of ethylene and exhibit desirable softening points and needle penetrations. The desirable combinations of softening points and needle penetrations in these propylene-ethylene copolymers allow them to have a broad operating window. Due their broad operating window, the propylene-ethylene copolymers can be utilized in a wide array of applications and products, including hot melt adhesives.

摘要： A matte synthetic paper is a biaxially oriented polypropylene synthetic paper having a thickness of 25 to 300 μm, and includes a printing surface layer as an outermost paper layer. Moreover, by adding a mist flour or a thermoplastic elastomer, the haze and gloss of the printing surface layer can be improved. According to Tappi T480, the printing surface layer having gloss of 15 to 50% is suitable to be printing paper.
