Buying in Bulk Saves Money
Buying packaging supplies in bulk reduces costs and ensures consistent inventory. In addition, bulk purchasing simplifies order fulfillment and improves efficiency.
Before buying in bulk, consider the following factors.
Choose the Right Material
Several material options are available:
-
Poly mailers – moisture resistant and flexible
-
Kraft padded envelopes – paper exterior with cushioning
-
Color mailers – professional branding options
For most shipments, poly mailers are ideal because they resist moisture and seal securely.
Choosing the Right Size
Selecting the correct size helps reduce shipping costs and prevent damage during transit. In general, allowing enough space inside the envelope ensures easier sealing and better protection.
Allow at least ½ inch of space inside the envelope for proper fit. Additionally, most padded envelopes have approximately ¾ inch less usable space than the outside dimensions.
For example:
A 6 × 10 mailer typically has usable space of about 6 × 9.25 inches.
