Rigid & Flexible Windowing

Rigid and flexible (cellophane-type) windows add a whole new dimension to packaging, creating a visible link between the packaging and the product itself. It is a perfect way to leverage the brand equity of the primary container or logo.

Maximum Visibility and Package Integrity

Diamond’s windowing capabilities include the application of a variety of materials, such as rigid (APET) and flexible (polyester) windows, providing you an effective method of displaying your products.
