Common questions
Are these envelopes compatible with all major shipping carriers?
Yes. The 4 1/2" x 6" size and "Invoice Enclosed" marking meet FedEx, UPS, and USPS document pouch standards, reducing scanning delays and ensuring carrier compliance without additional labeling.
How durable is 2 mil polyethylene for outdoor or wet shipping conditions?
2 mil poly provides excellent moisture resistance and tear strength for standard domestic and light international shipping. For extreme weather or repeated handling, consider upgrading to 3 mil thickness.
Can we order custom imprinting instead of standard "Invoice Enclosed" text?
Custom imprinting options are available for bulk orders. Contact our sales team for pricing on branded or specialized messaging (minimum order quantities apply).
What is the shelf life, and do these envelopes degrade over time?
Polyethylene envelopes remain stable for 2+ years when stored in cool, dry conditions away from direct sunlight. The adhesive backing maintains strength throughout standard warehouse storage.
