No liquids, or high temperature swings (hot or cold) and small quantity. The advantage is there is no artwork fee or set up fees most suppliers charge, no printing plates or printing cylinders. Digital printing can be done as Rollstock (where we provide rolls of printed film for a customer to use on their own equipment) or finished pouches (stand up pouches, flat bottom stand up pouches, or even flat-3 side seal bags). As a rule of thumb…less than 1000-2500 pieces per sku or flavor is perfect for digital.
