E-commerce and logistics packaging
DTC brands lose money twice on packaging: once on the bag, and once on returns and damage claims. This page covers the mailer and protective-film decisions that actually move your landed cost - PCR content, seal strength, sizes, printing and tamper evidence - from a manufacturer that supplies courier-ready packaging to e-commerce brands.
What shipping packaging has to survive
A mailer sits in a van, a sorting machine, three handlers and possibly a doorstep in the rain before it is opened. The two failures that matter are the bag splitting under a heavy item and the seal opening in transit - both show up as a damage claim that costs more than the bag. Tear-resistant film and a full-width self-adhesive seal are the non-negotiables.
Weight matters more than it used to: with carriers charging by dimensional weight, a mailer that is a few grams lighter or a size smaller saves real money at volume. We make to size, so the bag fits the product instead of the product rattling inside a default envelope.
PCR, GRS and the recyclability conversation
Many e-commerce buyers now need a sustainability story that survives an audit. PCR poly mailers and GRS-certified recycled content are the workhorse options - same seal strength, less virgin resin. If your category needs more, compostable structures are available for the niche that pays for them.
What we will not do is label a film recyclable when the collection stream cannot take it. Ask us for the certification documents and we will tell you which claim your market can actually make.
Sizes, printing and quick turnaround
Mailers run from small apparel bags up to 45x60 cm footwear sizes, printed up to 10-colour gravure or digitally for short runs. For a brand scaling from launch to wholesale, the same artwork and spec should carry across; we hold your print files and sizes on file so reorders are repeatable rather than renegotiated.
Tamper evidence and high-value shipments
Pharmaceutical, cosmetics and cash-in-transit shippers need more than a bag. Sequential numbering, barcodes and tamper-evident seals that leave visible evidence of opening are standard lines here, produced to the same AQL 1.5 batch documentation as the rest of the plant.

Frequently asked questions
What PCR percentage can poly mailers carry?
30-100% PCR is available, GRS-certified where needed; recycled content above 70% trades a little tear strength, which we compensate in gauge.
Can I get custom sizes and printed logos?
Yes - any size and up to 10-colour gravure or short-run digital printing, with artwork files held on file for repeat orders.
Do mailers have a tamper-evident option?
Yes - tamper-evident seals, sequential numbering and barcodes are available for high-value and regulated shipments.
What is the MOQ for custom mailers?
Depends on size and print; for plain stock sizes it is low, for gravure-printed orders it is set against the cylinder cost - quote within 24 hours of your spec.
How fast is production?
Samples in 5-7 working days, production in 20-25 working days after approval, shipped from Qingdao.
