Window Patch is an advanced post-press and die cutting technique that uses transparent PET or PVC film to create a clear viewing window on packaging, allowing consumers to see the product inside the box. In addition to enhancing visual appeal, this technique helps increase customer trust and creates a more premium product presentation.
Process Steps:
- Feeding the die-cut sheet
- Precise spot adhesive application
- Applying transparent film under controlled pressure
The final quality of the process depends on the type of film, adhesive viscosity, and registration accuracy. The result is a durable, visually attractive, and professionally finished package.
A specialized form of this technique involves applying Window Patch on the side walls or bottom of the box, commonly used in luxury packaging such as perfumes, premium chocolates, and decorative products.
