It depends on four things: how sensitive the product is to oxygen, moisture and light; how much shelf life you need; how you fill it (by hand, pre-made pouch filler, vertical or horizontal machine); and how it should look on the shelf. From there we start with the simplest structure that meets the need and add barrier only when necessary. If you already use a package that works, send us a sample: it is the fastest reference.

A pouch that withstands sterilization of the filled product in an autoclave, at 121–135 °C (250–275 °F) under pressure. You need it to keep a wet food (stews, sauces, pet food) shelf-stable at room temperature. It uses structures with nylon and retort-grade CPP, such as PET/ALUMINUM/BOPA/RCPP (opaque) or ALOX PET/BOPA/RCPP (transparent), and is validated with your sterilization process.

Start with the product: if it contains fat, aroma or oxidizes (coffee, snacks, nuts, vitamin powders) it needs oxygen barrier; if it is hygroscopic or crunchy, moisture barrier; if it is light-sensitive, opacity. Then the shelf life: more months, more barrier. With that we choose between a basic structure, a metallized one, one with EVOH or one with foil, and confirm it with a shelf-life test when the product is new.

Packaging machine make and model, web width and repeat, core diameter (76 or 152 mm / 3 or 6 in), maximum outside diameter, unwind direction, eye mark position and size, seal type (fin or lap) and sealing temperature. If you have a roll that already runs well, a section with its label answers almost everything.

In many cases, yes, with a mono-material polyethylene structure: MOPE/PE/PE white if your product does not require a high barrier, or MOPE/PE/EVOH PE if it needs oxygen barrier. Gauge, sealing and machine runnability must be reviewed, because MOPE behaves differently from PET. Actual recyclability depends on local infrastructure and we do not offer certifications.

You place your design on the dieline we send you and return the vector file. We check seals, eye mark, barcodes and colors, send you a proof and, with your written approval, the cylinders are engraved. Any change after that point means engraving new cylinders, with the cost and lead time that implies; that is why the review before approval matters so much.

Each lot arrives with the manufacturer's certificate: structure, gauge per layer, basis weight, lot number and the tests performed. We check it against your approved technical data sheet on receipt, and if anything does not match, the product is not released until it is resolved. The certificate stays linked to your order for any later inquiry.

Sometimes, yes: it is part of the advice we provide. Reducing gauge lowers material and cost, but also stiffness, strength and barrier, so product weight, filling method, transport and shelf life must be reviewed. The right way is to test the proposed structure on your line with your product before changing the specification.
