Basic Info.

Product Description

These waterproof stone paper letter envelopes are designed for businesses that need reliable, eco-friendly mailers in large quantities. Made from calcium carbonate and a non-toxic resin, the stone paper contains no wood pulp, no water, and no bleach, giving procurement teams a sustainable alternative to conventional paper envelopes. The material is naturally waterproof, so rain, spills, or humid storage conditions will not warp the envelope or smudge addresses and stamps. Unlike standard paper envelopes that tear easily during sorting or handling, this stone paper resists ripping and puncturing, helping protect invoices, contracts, letters, and promotional mailings throughout the postal journey. Bulk wholesale orders benefit from consistent sizing, clean edges, and uniform printability.

The practical performance of these stone paper envelopes makes them suitable for offices, mailrooms, legal firms, and direct-mail campaigns. The surface accepts handwriting, labels, and printing with sharp, legible results, while the moisture-proof nature keeps contents dry and presentable. The envelopes are lightweight yet strong, reducing postage weight without sacrificing durability. They can be supplied in standard letter sizes or custom dimensions, with options for window envelopes, peel-and-seal closures, or gummed flaps. Because the stone paper is tear-resistant, recipients can open the envelope without leaving paper fragments or damaging the contents inside, which improves the overall unboxing experience for important documents.

For volume sourcing programs, these stone paper envelopes offer consistent bulk quality, competitive pricing, and reliable lead times. The material is recyclable and photodegradable, supporting corporate sustainability goals and helping organizations reduce their environmental impact. Custom printing for logos, return addresses, or branding is available to match your business identity. Whether you are sourcing for daily office correspondence, client mailings, or large-scale promotional campaigns, these waterproof and tear-resistant stone paper envelopes provide a durable, eco-friendly, and professional solution for bulk wholesale orders.
