Common questions
Will these envelopes stick to my packages without additional tape?
These are document protector envelopes designed for insertion of loose papers (invoices, packing lists). Most models feature a self-adhesive strip for secure attachment to boxes, verify adhesive type with product specifications. Always test adhesion on your specific packaging material before full deployment.
Can I order custom text or branding on these envelopes?
This SKU features standard pre-printed 'Important Invoice and/or Packing List Enclosed' messaging. Packrift offers customization options on bulk orders (typically 5,000+ units). Contact our sales team for pricing and lead time on branded envelopes.
What's the advantage of 2 mil poly versus paper envelopes?
Polyethylene envelopes provide moisture and tear resistance, protecting documents from water damage during shipping and storage. They're ideal for humid environments, cold chain logistics, and high-moisture warehouse conditions where paper would deteriorate.
How many cases should I order for monthly fulfillment?
Calculate based on your average daily shipments: (Daily Shipments x Business Days x 30) / 1,000 = Cases Needed. Most mid-size fulfillment operations order 3-6 cases monthly. Packrift offers bulk discounts and flexible reorder scheduling to optimize your inventory turnover.
