Yes. The 4 1/2" x 5 1/2" size and 'Packing List Enclosed' pre-print comply with USPS Intelligent Mail barcode requirements and major shipping carrier standards (FedEx, UPS, DHL). Check your carrier's specific guidelines for any custom requirements.
How strong is the hot melt adhesive?
The hot melt adhesive provides permanent, weather-resistant bonding to corrugated cardboard, kraft paper, and most packaging substrates. Once applied, the envelope will not lift or peel during standard transit conditions, no additional tape or fasteners needed.
Can these be customized with our company logo?
