If you are a small business owner, ‘copacking’ or ‘co-packaging’can sound like a whole industry with its own secret language: doy bags, VFFS,flow wrap, multihead weighers.
It is not as complicated as it sounds, and understanding the basics can help you make better decisions about how your product ends up on the shelf.
Here is a simple breakdown of the most common packaging formats we run and how each one actually works.
Most flexible packaging (doy bags, vertical form fill bags, and flow wrap) runs through some version of the same core process.
The product is fed into a machine where each portion is weighed out. The right weight is then dropped down into the bag. The bag is sealed shut, labelled, checked and shipped.
The main difference is the bag. They come in different shapes and sizes.
Doy Bags
Doy bags are pre-made, stand alone bags. They stand up on a shelf with a flat bottom. Because they arrive as individual, ready-formed units, the task is simple: open the bag, fill it, and seal across the top. This makes doy bags a popular choice for retail-ready products that need to look good standing upright on a shelf.
Vertical Form Fill Bags
This format forms the bag itself from a roll of film as part of the packing process. The film is shaped into a bag, filled with product, and sealed along the top, bottom and back. It runs on the same type of line as a doy bag, but has the extra step at the start to create the bag itself. This format is often a more cost-effective option at large scale.
Tubs
The product is weighed out into a tub placed automatically or manually underneath the weigher. This is a great option for products where a rigid, stackable container makes more sense than a flexible bag, for instance for powders or portioned snacks.
Flow Wrap
Flow wrap is a product sealed with a seam along the top,bottom and back for individually wrapped items like bars, baked goods, or single-serve snacks.
The packaging format you choose affects more than just how your product looks. It influences cost per unit, shelf presentation and space, shelf life, and how efficiently your product can run through production.
