Video: Flexible Packaging Films at Alpine

In this video, you can see how Alpine prepares a printed, unsupported flexible packaging film for a customer.

First, the white flexible packaging film was printed with the customer’s information. Next, a clear UV adhesive was applied to the film. This UV adhesive serves to adhere the laminate, which is a clear flexible packaging film, to the printed white film. The laminate protects the ink while also giving the film more strength and durability.

That complete printed and laminated film is what you are seeing in this video. The rolls of flexible packaging films each have three images across the web, so they must be slit to put a single image on each roll. Depending on the customer’s requirements, the prepared films are placed on either a 3” or a 6” core.

These films will be used on single serving plastic bottles for drinks, such as chocolate milk or fruit juice. Alpine delivers the rolls of completed films to the customer. They then use their own machinery to lay down glue, wrap the bottle in the film, cut the film and then glue the other end of the film down. Alpine prints bar codes at the end of each film, which alerts the customer’s equipment that the film should be cut at that point for the correct length.
