Common questions

Will the hot melt adhesive stick to wet or damp boxes?
Hot melt adhesive performs best on clean, dry surfaces. For optimal adhesion, ensure corrugated or paper surfaces are free from excess moisture, dust, and oils before applying the envelope.
Can these envelopes be removed and reapplied?
No, the hot melt adhesive is permanent once applied. The strong adhesion prevents repositioning, ensuring documents remain securely attached throughout the entire shipping and delivery process.
What documents fit inside a 4 1/2" x 6" envelope?
Standard 4" x 6" packing lists, invoices, shipping labels, and documentation fit comfortably. The envelope accommodates multiple folded sheets or thicker paper stocks up to approximately 1/8" thickness.
Why choose red envelopes over other colors?
Red is highly visible during sorting and delivery, reducing the risk of missing or overlooked packing lists. The bold color combined with pre-printed text ensures maximum visibility in high-volume warehouse environments and during final delivery verification.
