Curwood’s UltraSeal film is a new material for shredded cheese applications that is specifically formulated to maximize the performance of ultrasonic sealing on high-speed vertical form-fill-seal gas-flush equipment.
By Gretchen Edelbrock, Products Editor
UltraSeal is engineered for the unique requirements of natural shredded cheese, including advanced oxygen barrier, abuse resistance and reliable sealing through contamination.
UltraSeal film also seals well through small pleats and wrinkles to eliminate leakers and improve package yield. The high vibration used in the ultrasonic sealing process is able to shake away fines from the seal area, such as shredded, powdered or grated cheese, that might otherwise compromise a traditional heat seal.
