foreach loop displaying below content summary

You can hook into the action like this:

Code:

add_action( 'woocommerce_after_shop_loop_item', 'wpse124226_wc_product_attribute_list' );
function wpse124226_wc_product_attribute_list() {
    $value = get_the_terms( $product->id, 'pa_package');
    echo "<ul>";
    foreach ( $value as $values ) {
        echo "<li>";
        echo $values->name;
        echo "</li>";
    }
    echo "</ul>";
}

Take a look at the codex Plugin API to inform yourself about using hooks. BTW you can use woocommerce functions to get the attributes, especially get_attributes, take a look at the source at the woocommerce documentation. For an use-case take a look at the product-attributes.php file.
