Common questions
Will these envelopes stick to wet or damp corrugated boxes?
The hot melt adhesive works best on clean, dry surfaces. For optimal adhesion in humid environments, ensure corrugated is dry before application. The 2 mil poly material protects enclosed documents from moisture regardless of exterior conditions.
Can I reposition these envelopes after application?
Hot melt adhesive creates permanent bonds once applied. For maximum hold strength, apply firmly and allow 30 seconds for proper adhesion. Plan envelope placement carefully before application to avoid repositioning.
What size packing slip fits in these envelopes?
The 5 1/2" x 10" envelope accommodates standard packing slips up to 5 1/4" x 9 3/4" folded or smaller unfolded documents. The open-along-dimension design allows easy insertion and removal.
Are these envelopes compatible with automated packaging systems?
Yes, the consistent 5 1/2" x 10" size and pre-applied hot melt adhesive make these suitable for semi-automated and manual fulfillment environments. Check your specific system's adhesive specifications before deployment.
