Common questions
Will the hot melt adhesive damage my corrugated boxes?
No. Hot melt adhesive is specifically formulated for corrugated and paper surfaces. It bonds securely without degrading box integrity, and won't leave residue if removal is necessary.
Can these envelopes hold documents larger than 5 1/2 inches?
These envelopes accommodate standard 8.5" x 11" documents folded once, or smaller documents flat. The 4 1/2" x 5 1/2" opening is optimized for typical packing lists and shipping labels.
Why orange instead of white or clear?
Orange provides maximum visibility in high-speed sorting environments and during package handling, reducing missed documents and improving compliance verification rates. The bold color also enhances brand presentation.
How many cases should I order for typical monthly volume?
Calculate your daily shipments and multiply by 20-25 business days. Most mid-size fulfillment centers process 500-2,000 packages daily. We recommend maintaining 2-4 cases in inventory to prevent stockouts.
