The food packaging material includes a plurality of grooves formed on one surface of the food packaging material; and an oil layer uniformly applied to the one surface of the food packaging material, being put into the grooves. According to the present invention, there are provided a food packaging material which continuously maintains a uniform coating of oil and thus minimizes sticking of contents to a surface of the packaging material, a method of manufacturing the same, and a mold for manufacturing the same.
Abstract:
Disclosed is a vibration module for a portable terminal that includes a housing, a magnetic moving part movable in a first direction within the housing; an elastic member supported between the opposite ends of the magnetic moving part and inner walls of the housing, and a solenoid coil provided in the housing. The vibration module is positioned at one end of the moving section by the magnetic force of the magnetic moving part and an object around the magnetic moving part, allowing the vibration module to provide a user with a feeling similar to a click feeling via the acceleration produced at a stopping instant. In addition, when vibrating, the vibration module generates sufficient vibration power through acceleration at the instant of changing moving direction at the ends of the moving section, to provide an alarm function, such as an incoming call notification.
