The weight of your product helps determine which packaging you need. Light products usually work well in standard flexible packaging, such as snacks, powders or dried ingredients. Heavier products, like liquids, bulk goods or pet food, require stronger materials. This often means thicker films or an extra layer, such as nylon, to prevent tearing or sagging. For heavier contents, also check seal strength, bottom construction and the type of closure. Everything must handle the weight and stay safe during transport. Testing is key, feel free to request samples.
