Hi aderojas,

use 'rewrite' => array('slug' => 'your-slug-here'),

here is an example

register_post_type(
		'portfolio',
		array(
			'labels' => array(
				'name' => 'Packages',
				'singular_name' => 'Package'
			),
			'public' => true,
			'has_archive' => true,
			'rewrite' => array('slug' => 'package-type'),
			'supports' => array('title', 'editor', 'excerpt', 'thumbnail','comments'),
			'can_export' => true,
		)
	);

remember to refresh the permalink settings.
