B5 HK WHITE ENVELOPE WITH ADHESIVE STRIP 250 PCS ! 

B4 - (250 x 353 mm)

Self-adhesive gluing with a strip (HK) - closing an envelope with such gluing is done by pulling off the strip covering the 
glue, putting on the flap and pressing on the envelope flap and it is already firmly closed. Fast, safe, clean, practical and 
convenient. This strip has a decisive advantage over wet gluing or self-adhesive closing. Envelopes really store much better 
because the seal is protected by the strip, lasts longer and does not stick to the envelopes lying below. In addition, envelopes 
with such gluing are easier to fill and maintain their validity (warranty), which is over 5 years. It should also be added that 
envelopes with this gluing can be printed on without any problems, because the covering strip lies on the opening flap, which means 
that these envelopes do not stick to the printing device.
