1. Pick the shipping profile

FlexibleApparel, textiles, soft goods: start with poly mailers.
Light cushionBooks, documents, small goods: compare padded mailers.
StructureGlass, candles, kits, rigid items: start with corrugated boxes.
SeparationMulti-item or loose-fill shipments: add cushioning.

3. Compare the formats

Format Use when Check before ordering Move up when
Poly mailer The item is flexible, already protected, and does not need rigid structure. Usable size, thickness, closure style, opacity or color, and case quantity. The package becomes bulky, hard to close, sharp-cornered, or damage-sensitive.
Padded mailer The item needs light surface cushioning without a full carton. Inside usable size, cushioning type, closure, and packed item thickness. Edges, corners, stacking, or presentation require a corrugated box.
Corrugated box The item is rigid, fragile, heavy, multi-item, stacked, or presentation-sensitive. Inside dimensions, board grade, carton style, void fill needs, and bundle quantity. The carton leaves too much empty space or a specialty mailer fits better.

Common mistakes to avoid

  • Using a plain poly mailer for crushable, sharp-edged, or presentation-sensitive items.
  • Choosing a mailer that barely closes once the item is packed.
  • Ignoring packed thickness and only measuring flat length and width.
  • Using a box without enough cushioning or separation for multi-item shipments.
  • Reordering from memory without checking current SKU, selected variant, sold-as unit, and pack count.

FAQ

How do I choose quickly?

Start with risk. Flexible and already-protected items usually start with a poly mailer. Items needing light surface cushioning start with a padded mailer. Rigid, fragile, heavy, sharp-edged, or multi-item shipments usually start with a corrugated box.

Are the product examples live Packrift products?

Yes. The examples on this page were pulled from live Packrift collection data when the page was built. Confirm the linked product page for current SKU, selected variant, dimensions, sold-as unit, pack count, price, and availability before checkout.

Can apparel ship in a poly mailer?

Many apparel shipments can use a poly mailer when the item is flexible and does not need crush protection. Confirm packed size, mailer thickness, closure style, and sold-as quantity before ordering.

When should I use a padded mailer?

Use a padded mailer when the item needs light surface cushioning but not a rigid carton. If edges, corners, stacking, or presentation matter, compare a corrugated box.

When is a box the safer choice?

A corrugated box is the safer starting point for rigid, fragile, sharp-edged, heavy, presentation-sensitive, or multi-item shipments that need cushioning or separation.

What should I measure before buying packaging?

Measure the packed item length, width, and thickness after any inner wrap or retail packaging is included. Then check the product page dimensions, selected SKU, sold-as unit, pack count, price, and availability.

What is a common repeat-order mistake?

Reordering from memory without checking the current SKU, selected variant, sold-as unit, and pack or case quantity can create mismatched inventory. Confirm the product page before checkout.
