Decoration

Labels

Major decoration methods for PET bottles are labeling and screen printing. Due the varying application methods, labeling is classified into shrink labels, stretch labels, wrapping labels and tack labels.

Shrink Labels

Cylindrical heat-shrinkable film is cut and placed on bottles as labels and then shrunk by hot air so that it tightly fits the bottle.
Polystyrene (PS) and PET are used as the materials. The label can be added before or after the filling process.

Shrink Labels
Stretch Labels

Cylindrical resilience film is cut, expanded by stretching, and then placed as a label over the bottle. Labels are attached on a waist portion only.

Stretch Labels
Wrapping Labels

Band-shaped labels are attached to bottles by wrapping. Adhesive is applied on the overlapping portion of the label to fix its position.

Wrapping Labels
Tack Labels

Labels with adhesives are placed on the bottles. Paper, laminated paper, and synthetic paper are used as the materials. Tack labels are widely used on bottles for alcohol such as Shochu (distilled spirit), food oil and detergents.

Screen Printing

Screen printing is a method of printing applied directly on the bottles so to achieve a characteristically unique visual impact.
