You should be able to get the desired output of SKU:1018,1026 with something like:

$prefix = "SKU:"
foreach ($new as $item) {
    $product_id = $item['product_id'];
    $prod = new WC_Product($product_id);
    $sku = $prod->get_sku();
    echo $prefix . $sku;
    $prefix = ",";
}

This simply sets the initial prefix to SKU: then, for each item, outputs that prefix followed by the item number. After the first one is output, it sets the prefix to , so that subsequent items will be preceded by that comma.
