Common questions
Will documents remain readable through the envelope after extended shipping time?
Yes. The clear polyethylene face maintains optical clarity throughout the shipping lifecycle. The 2 mil thickness provides durability without haziness, ensuring barcode scanners and human handlers can read packing slips, invoices, and tracking numbers consistently.
How does the adhesive strength compare to thicker poly envelopes?
The 2 mil poly delivers adhesion strength specifically engineered for shipping environments. The self-adhesive backing creates a permanent bond that resists moisture, temperature fluctuations, and handling friction, preventing envelope separation without requiring additional tape or fasteners.
Are these envelopes considered tamper-evident?
Yes. The 2 mil poly construction with sealed edges creates visible tamper evidence. Once the envelope is opened, the adhesive bond breaks visibly, making tampering immediately apparent to customers and fulfillment teams, essential for compliance and loss prevention in high-value shipments.
What document types fit the 4" x 3" format?
These envelopes accommodate standard packing slips (folded), invoices, return labels, QR codes, barcodes, and compliance documentation. The compact size is ideal for attaching to package exteriors without creating excessive bulk while keeping critical shipment information immediately visible.
