These entry points turn a broad packaging question into a visible next step: what to send, what Sparal checks, and which proof path moves the buyer closer to a quote.
001 / Equipment guide
Best heat sealers for mylar bags
Which heat sealer type actually fits mylar bags and foil pouches — impulse sealers, continuous band sealers, and chamber vacuum sealers ranked for small-batch production.
002 / Equipment guide
Impulse sealers for stand-up pouches
For stand-up pouches, buy an impulse sealer with a jaw at least 25 mm wider than your pouch and a 5 mm element. The wider jaw bridges the gusset shoulders; the wider element forgives slight misalignment when you are sealing by hand.
003 / Equipment guide
Impulse vs band sealer
The switch-over point is throughput, not seal quality — both machines produce retail-grade seals when set correctly. Hand pace on an impulse sealer tops out around 200-400 pouches per shift; a band sealer runs that in an hour.
004 / Equipment guide
Heat sealer settings by material
Seal temperature is set by the sealant layer (almost always PE), but the layers above it steal heat. That is why foil laminate needs 10-20°C more than plain PET/PE at the same dwell, and why mono-PE needs less — there is nothing in the way.

Each guide starts with a concrete buyer question, then turns it into quote fields, proof points, FAQ answers, and a clear next step.
