You need a double-seal-strip mailer for returns
Primary lip-and-tape for the outbound, a second strip for the customer to reseal on return. No extra envelope inside the box. Spec'd as a single line item on your quote.

Conversion
Two converter lines that take printed film off the press and turn it into the finished, sealed, packed bag your warehouse expects.
7.8M bags / month
Conversion is the last mile of the bag — the difference between a printed roll of film and a case of mailers ready to drop on your warehouse line. Two converter lines (M1 primary, M2 secondary) give us scheduling flexibility: long runs at high throughput on M1, fast-changeover small batches and specialty configs on M2.
Every common closure format — J-fold lip-and-tape, side-weld seal pouch, double seal strip for returns, vented warning bag, open-top kit bag — and packaging that lands at your dock the way your bagger / pick-station expects it. Case counts, palletization, and SKU labels configured per customer.

Real situations we run against.
Your warning bag spec requires vent holes
Standard pattern on all suffocation warning bags — the vent prevents the bag itself from being a hazard. Matches CPSC and Amazon FBA expectations exactly.
Your bagger is running at 90 bags/min and choking on stiff film
We can adjust the gauge or layer balance on the extrusion side AND tune the conversion seal so the finished bag has the right hand-feel for your line. Sample a test lot on YOUR bagger before locking the production order.
You want 200 bags per case with a SKU label on the long edge
Case counts and label position are configurable per SKU. Tell us what your warehouse expects and we'll match it.
A retail program needs a hanger hole or kit-bundling tab
Both are routine. Hanger holes punched inline; kit tabs welded as part of the conversion pass.
