I looking to buy this vacuum pack machine. http://www.ecateringonline.co.uk/va...g-lowest-price-in-the-uk---ex-demo-2059-p.asp The supplier only offers embossed bags. I have thousands of plain bags in storage. Its an affordable machine but I am self employed and cost is everything to me. do all table top vacuum pack machines accept plain bags? Or do only certain types of bags work for certain types of machines?
