  Seal width refers to the thickness of the sealing line applied to the pouch. In office environments, a narrow seal (typically 2–5 mm) is preferred for precision and minimal visual impact on documents. These thinner seals are ideal for standard plastic pouches used in binding reports, presentations, and certificates.

  Wider seals (6 mm and above) are generally used in industrial or warehouse settings where thicker, heavy-duty pouches require stronger, more durable sealing. While not common in offices, wider seals offer greater strength and are less prone to peeling under stress.

  Seal length determines the maximum width of the pouch that can be sealed in a single pass. Compact desktop models typically support seal lengths of 200–300 mm, sufficient for A4 or letter-sized documents. Larger models may offer seal lengths up to 400 mm or more, accommodating wider or custom-sized pouches.

  Selecting a sealer with an appropriate seal length ensures full coverage across the pouch edge, preventing weak spots or incomplete seals. Always match the sealer’s capabilities with your most commonly used pouch sizes.

• Temperature Control

  Precise temperature control is crucial for achieving consistent, bubble-free seals across different pouch materials. Most plastic laminates (such as PET or BOPP) require a sealing temperature between 150°C and 200°C. Temperatures below this range may result in weak seals, while excessive heat can cause scorching, warping, or melting of the pouch.

  High-quality sealers feature adjustable thermostats or digital temperature displays, allowing users to fine-tune settings based on pouch thickness and material type. For example:

  • Thin pouches (60–80 microns): 150–160°C
  • Medium pouches (100–125 microns): 170–180°C
  • Thick or double-sided pouches (160+ microns): 185–200°C

  For environments requiring high consistency—such as print shops, legal offices, or packaging departments—temperature-stable models with rapid heat-up and recovery times are recommended. Always consult the pouch manufacturer’s specifications to avoid damage and ensure optimal adhesion.
