The short answer: choose by the actual outer diameter of the cup rim, not by the cup’s volume or brand model. Beverage cups commonly come in two rim sizes — 90mm and 95mm. The two are not interchangeable on the same sealing die: picking the wrong one causes misaligned seals, leaks, or wasted film. If […]

The short answer: the film must match the cup material to seal reliably. As a rule — PP cups pair with PP-based film, PET cups pair with PET-compatible film, and PE-laminated paper cups pair with PE-compatible film. Mismatch the materials and the seal may peel open or fail to bond even when the machine temperature […]

The short answer: a weak seal is rarely one cause — it’s one of five variables out of balance: temperature, time, pressure, film, and container. The most common order is: wrong temperature > film/cup mismatch > debris or deformation on the rim > dirty or worn sealing die > insufficient pressure or alignment. Checking each […]

The short answer: the difference between desktop and industrial machines comes down to output scale and whether it integrates into a production line. A desktop machine is compact, stands alone on a counter or workbench, and suits outlets and small-to-mid output. An industrial machine has high output, often integrates filling and continuous conveying, and is […]
