Plastic packaging design patterns refer to the artistic or functional arrangements of graphics, symbols, or text on plastic packaging materials. These designs can serve various purposes, such as branding, product identification, or enhancing the product's appeal. The choice of patterns depends on factors like brand identity, target market, and product characteristics. Designers often use software like Adobe Illustrator or Photoshop to create these patterns, which are then printed onto plastic packaging using various techniques like flexography or offset printing.
