What Are Poly Mailer Bags and What Are They Used For?
Contents
Poly mailer bags are lightweight, durable plastic envelopes used primarily for shipping non-fragile items. They are an ideal packaging solution for:
-
Clothing and apparel
-
Books and documents
-
Cosmetics
-
Electronics accessories
-
Subscription boxes
These bags are designed to protect goods from moisture, dirt, and tampering during shipping—without the extra weight and bulk of boxes.
What Is the Material Used in Poly Mailer Bags?
Poly mailer bags are typically made from:
-
HDPE (High-Density Polyethylene) – Strong, stiff, and affordable
-
LDPE (Low-Density Polyethylene) – Softer, more flexible, and stretchable
To help reduce environmental impact and manufacturing costs, many factories—including Vietpak—offer the option to include recycled materials in the production process.
Benefits of using recycled content:
-
Lower overall cost
-
Supports circular economy
-
Reduces plastic waste
