Bubble Expandable Envelopes

Expandable Envelopes with Bubble Lining

Gusset Bottom Expandable Envelopes with Bubble Lining

Expandable envelopes with gusseted bottom and bubble lining are great for shipping thick, bulky items that do not fit in standard size bubble mailers.

These innovative expandable poly mailers eliminate the need for expensive and inconvenient boxes with void fill because it expands to fit and protect larger e‑commerce shipments.

Poly bags with gusseted bottom are ideal for less fragile bulkier shipments such as documents, books, catalogs, shoes, clothing, bedding, blankets, stuffed soft toys and pharmaceuticals.

Details
  • Durable polyethylene is tear and puncture resistant.
  • Self-seal adhesive closure is tamper‑evident.
  • 3/16” bubble lining for maximum protection.
  • Dual Peel and Seal Option allows customers to reseal and reuse the original packaging, for truly hassle free returns.
  • Puncture resistant, tamper and water proof.
  • Ideal for bulky apparel, books and purses.
