Abstract:
This research was aimed to do packaging design of plastic bottle for green tea drinks in terms of
shape and label color and to determine the satisfaction of green tea drink consumers (pupils,
students and general public) between 15-30 years of age living in Bangkok towards the packaging
design of plastic bottle for green tea drinks. Documents and researches work related to packaging
design were reviewed. Then 30 packaging types of plastic bottle for green tea drinks with different
shapes and label colors were designed. Only 10 were chosen by the experts and were used in an
interview with the sampling group of 40 persons in order to choose the top 3 satisfactory packaging
designs using frequency, percentage and ranking by gender and age group. Then they were used in
an interview with the sampling group of 80 persons in order to choose only I most satisfactory
packaging design. The research results revealed that the plastic bottle for green tea drinks with
triangular shape (Bottle type 6), greenish yellow label color, Japanese-like font as well as virtual
images with graphic illustrations gained the most satisfaction from the sampling group (51.25%).
The runners-up were plastic bottle with gourd shape (Bottle type 10) with greenish yellow label,
free form font and graphic illustration (36.25%) as well as tube-shaped plastic bottle (Bottle type 5)
with 6 striped angles, greenish yellow label and virtual images with graphic illustrations (12.50%),
respectively. However, the sampling group with different genders and ages showed the same
satisfaction. Therefore, the researchers suggested the manufacturers use the packaging design of
plastic bottle for green tea drinks in order to comply with the satisfaction of the consumers in the
future.
