heat seals
A good heat seal is a complete
circle with even thickness. If the
seal looks incomplete or de-
formed, repeat the vacuum seal-
ing process in the exact same
location.
GOOD BAD BAD
COMPLETE HEAT SEALS ENSURE THAT
YOUR BAG IS AIRTIGHT.
BAD BAD
When you are reusing a bag do
not overlap the sealing circles as
illustrated above. Sealing circles
that are overlapping will not have
an effective airtight seal.
*Note: You may overlap sealing
circles if you are attempting to
fix a broken seal.
DO NOT OVERLAP SEALING CIRCLES *
