Printed foil and film pouches with a press zip set a little below a sealed top strip, so the bag is torn open once and then reclosed. Stand-up or flat, with or without a hang hole. Orders start from 100 units.
A zipper mylar bag has two closures, and they are used in a fixed order. One is a heat seal, opened once, by tearing. The other is the press zip, used again and again, by whoever buys it.
A bag that is going to be filled has to reach you with one end still open, and once it is full that end is heat-sealed shut. That seal is made at your end, on your bench or your packing line, so a heat sealer is part of filling zipper bags, not an extra. Where the open end is the strip above the zip, leave the zip open while you press out what air you can. Then close the zip and seal the strip, which is the seal your customer later tears away. Planning to add oxygen absorbers? 1 Gallon Mylar Bags explains why that is worth mentioning before the bag size is fixed.
The small notch cut into the side edge sits level with the sealed strip. Your customer tears across from the notch, which takes the sealed strip off and leaves the zip below it ready to use. From then on the zip is the closure. Mylar Food Storage Bags goes into what a zip does each time the bag is reopened, and what it cannot do.
A stand-up pouch has a folded gusset in its base that opens out as the bag fills, so a filled bag stands on a shelf with its front facing out. A flat pouch has no gusset and lies flat, which suits a smaller fill, a sachet or a bag that goes into a box or a postal envelope. A hang hole punched through the top strip lets the bag hang from a peg on a display stand. Because the hole sits in the strip above the zip, it goes when the bag is torn open, and the zip below is left whole.
The bag is built from layers of PET film, often with aluminium foil, chosen for what goes inside, and the protection it gives depends on that construction. Offset, digital or screen printing puts your design on the film, with the process chosen for each order. Food-contact material suitability is confirmed for the specific material before production.
Design support is free. A digital 3D mock-up is free. There are no setup fees. Standard production takes 6 to 8 business days after approval. UK delivery is free.

Yes. The open end of the bag is sealed by you after filling. On a top-filled bag, leaving that strip unsealed means the zip is the only closure from the moment the bag leaves you, and there is nothing for the customer to tear open.
An unlaminated paperboard construction may be easier to process through suitable paper-recycling streams than a heavily laminated alternative. Final recyclability depends on the full material and finishing specification and the facilities available locally. A zipper pouch is a layered film, usually with foil, so it is at the laminated end of that line. We can explain the general recyclability considerations of the selected material and finishing options, so you can make accurate claims on your own packaging.
