Envelope Mailers

Measure the item(s) and add clearance for padding; choose rigid board-backed mailers for flat documents, bubble or padded poly mailers for small soft items, and large kraft or poly mailers for bulky but lightweight goods. Match mailer dimensions to common shipping envelope sizes (e.g., A4, letter) and ensure thickness provides adequate protection

Common materials are kraft paper, bubble-lined poly, padded kraft, and rigid board or corrugated mailers; bubble or padded linings offer impact protection, poly is water-resistant, and rigid mailers prevent bending. Choose based on vulnerability to bending, moisture exposure, and required tamper resistance

Individual mailers vary widely with prices influenced by material, size, and protective features; budget options are typically under $50 for small pack quantities while commercial bulk packs range higher. For frequent shipping, compare per-unit cost when buying 100+ or 1,000+ packs to find economical scale pricing

Use mailers with strong adhesive strips or peel-and-seal closures, consider additional tamper-evident tape or security labels for high-value items, and ensure seal surfaces are clean and dry before applying closures. For extra security, void-pattern tape or heat-activated seals increase tamper evidence

Many suppliers offer customization like printed logos, sizes, and colors, often requiring minimum order quantities; lead times vary by vendor and complexity but commonly range from a few weeks to a couple of months for production. Request proofs and confirm print methods (digital vs. flexographic) to ensure artwork fidelity

Store mailers flat or upright in a cool, dry place away from direct sunlight and high humidity to prevent adhesive degradation, warping, or moisture damage; keep them in original packaging until use and avoid stacking heavy objects on top. For poly mailers, avoid sharp objects that could create punctures during storage
