NOTES-SideSeamEnvelopes
l Envelopedimensionsshouldnotvarymorethan.0625"(1.6mm).
l Sideseamsshouldbesecurelybondedtothebackflapwithoutanycurlorripplebetweenback
flapandsideseams.
l Sideseamsshouldhavetheadhesivelinewithin.0625"(1.6mm)ofthetopedgeofthebackand
within.25"(6.4mm)oftheinneredgeofthesideseam.
l Allwindowpatchesshouldbeflat,ripplefreeandbondedwithin.0625" (1.6mm)ofthetopedgeof
thepatchmaterialandtopedgeofthewindowcutout(s).Ifthewindowpatchareaisonethirdor
moreofthetotalareaoftheenvelope'sfrontpanel,thentheenvelopemustbetested.
l Inthosecaseswhereanypartofthesideofthepatchmaterialiswithin1.0"(25mm)fromany
envelopesideedge,thefollowingapply:

o
Ifthetopofthepatchmaterialfallswithin.375"(9.6mm)ofthecreasescoreline,thepatch
materialshouldberaisedtowithin.0625"(1.6mm)orclosertothecreaseline.

o
Thethroatshouldbeatleast.25"(6.4mm)belowthecreaselineat.75"(19mm)fromtheside
edges.Thisisrequiredtopreventthethroatopenersfromtearingthepatch.
l Envelopecurlortwistshouldnotexceed.25"(6.4mm)whenenvelopeisplacedonaflatsurface.
l Inopenwindowenvelopes(nopatch),thewindowshouldbelocated.75"(19mm)minimumfrom
eitherside,topandbottomoftheenvelope.
l Paperstockmayrangefrom20lb(75gsm)minimumto28lb(105gsm)maximum,but24lb(90
gsm)issuggested.
l Topedgeofthesideseamshouldbeevenwithorupto.0625" (1.6mm)abovetopedgeofthe
backpanel.
l Maximumflapdepthonminimumlengthenvelopesis2.75"(69.8mm).
l Thelengthoftheenclosureshouldnotbeequaltothedistancebetweenthesideseamedges.
Whenpossible,theenclosurelengthshouldbegreaterthanthisdimension,withconsiderationthat
thecorrectendclearanceismaintained.
l Envelopeswhosecharacteristicsfalloutsideoftheseconstructionguidelinesmustbeevaluatedby
PitneyBowes.
l Distancebetweenthegluelineandtheenvelopeedgeshouldbe.125"orless.
