In mold labeling (IML) is a labeling method in which a preprinted decorative film is placed into a mold before the plastic container is shaped into that mold. Plastic pellets or resin are heated and placed into the mold where it merges with the label to create a single product.
Blow molding – Blow molding is similar to glass blowing. Like injection molding, the label is inserted into the mold before it is combined with the plastic. However, instead of injecting plastic into the mold, it is blown in using an air stream. Once expanded into the desired shape, the label melds to the container.
