Question 1

What products are best suited to poly mailers versus corrugated boxes for e-commerce shipping?

Accepted Answer

Soft goods that don't require impact protection: apparel, t-shirts, hoodies, leggings, accessories, fabric-based products, non-breakable jewelry, lightweight footwear, and flat non-fragile items. Poly mailers save significant shipping weight (0.5–2 oz versus 4–8 oz for corrugated) which reduces carrier cost meaningfully at volume. For products requiring crush protection or fragile items, corrugated remains the appropriate choice.

Question 2

How do custom poly mailers affect customer unboxing experience compared to boxes?

Accepted Answer

The tactile experience is different but still brand-meaningful. A high-quality poly mailer with a satisfying tear-strip opening, well-considered interior tissue wrap, and a printed brand element inside creates an experience appropriate to the product category. Fashion brands in particular use poly mailers with confidence because the casual-but-considered opening experience matches the brand's accessibility positioning. Premium brands that need the full unboxing ritual benefit more from boxes.

Question 3

What print options are available for custom poly mailers?

Accepted Answer

Full-surface flexographic printing in 1–8 colors is standard. Matte finish creates a premium soft-touch aesthetic. Gloss finish maximizes color vibrancy. Metallic ink is available for accent elements. White base on poly mailers provides the most accurate color reproduction. Kraft-finish poly mailers provide a sustainable-looking aesthetic with the waterproof poly performance. Full bleed, all-over pattern designs, and photographic prints are all achievable.

Question 4

Are poly mailers environmentally appropriate for brands with sustainability commitments?

Accepted Answer

This is the most complex sustainability question in e-commerce packaging. Standard poly mailers are recyclable through plastic film drop-off programs at major US retailers (not curbside recycling) — a significant infrastructure limitation. Compostable poly mailers (made from PBAT/PLA blends) require industrial composting facilities that aren't universally available. Recycled-content poly is available and represents a meaningful improvement over virgin plastic. For the strongest sustainability position, paper mailers (less water-resistant but recyclable curbside) are an alternative for appropriate product types.

Question 5

How do I calculate the dimensional weight for poly mailers versus corrugated boxes?

Accepted Answer

Poly mailers are typically billed on actual weight for lightweight items because their dimensional weight (Length x Width x 0.5 / 139) is often lower than actual product weight for soft goods. Replacing a corrugated box with a poly mailer for a 12 oz apparel item can save $1.50–$3.00 per shipment in carrier cost depending on the corrugated box dimensions that would have been used. For high-volume apparel brands, this is a material cost efficiency.

Question 6

What security features do custom poly mailers include?

Accepted Answer

Self-adhesive peel-and-seal closure with tamper-evident tape is standard. Once sealed, the adhesive strip creates a bond that cannot be reopened without visible damage. A second adhesive strip allows the customer to reseal the mailer for returns — a feature that reduces friction in return programs. Some brands add a one-way security window or barcode area for internal tracking. The tamper-evident closure is the primary security feature that protects product integrity in transit.

Question 7

Can custom poly mailers include interior branding or is only the exterior printable?

Accepted Answer

Interior surface printing is available on some poly mailer configurations — a different color or message on the inside surface creates a brand moment when the mailer is opened. Standard poly mailers are printed on the exterior only, with the interior remaining plain or white. For brands where the unboxing experience matters, combining a well-designed exterior with a tissue-wrapped interior achieves the dual-layer brand experience without requiring interior print.

Question 8

What's the MOQ and cost structure for custom poly mailers?

Accepted Answer

PackTist's MOQ is 500 units. Custom poly mailers represent one of the most cost-effective custom packaging investments available — unit costs at 500 pieces for a custom-printed mailer typically range from $0.30–$0.80 depending on size and print complexity. For apparel brands shipping 200+ orders monthly, 500 units covers roughly 2–3 months of supply. At 1,000+ units, per-unit costs decrease meaningfully.
