Operator skill and fatigue: Manual impulse sealing is a repetitive task, and the operator's speed and consistency will directly affect output.
Material thickness and type: Thicker and denser films, such as Mylar, require longer heating and cooling times than thinner materials like polyethylene, which slows down the process.
Cooling time: The cooling phase is critical for creating a strong, durable seal. Rushing this step can result in weak seals.
Automation level: Higher-end models, such as foot-operated or automatic continuous band sealers, can achieve significantly higher speeds. Manual 300mm units are typically for low to medium-volume applications.
Bag contents: Products with dust or liquids that get into the sealing area can interfere with the bond, requiring more attention and potentially multiple sealing attempts.
