Quality Assurance
Container Packaging
To ensure compliance with the law and safety, we examine the expected risk for each type of container, such as cans, bottles, plastic bottles, and paper packs, at all phases, from material selection to design and manufacture.
Guaranteeing quality in terms of both usability and strength
Since container packaging is regarded as an important aspect in product quality, we both design and evaluate it. Various tests have shown that the design is as intended and that there are no issues with the product.
Usability*
The adhesive strength of plastic bottle labels is investigated by user tests to determine the strength in which consumers find it easy enough to peel off. Machines are also used to test the adhesive strength of the manufactured product. Similarly, user testing and other tests indicate the ease with which caps and cans can be opened.

Strength tests
We drop cans and PET-bottled beverages as cardboard boxes for the test, anticipating a scenario when carrying luggage, to ensure that the contents do not leak as a result of the impact of the drop.

New challenges for high quality container packaging
Performance and components required for containers vary, including robustness, usability, appealing design, and weight reduction.
Suntory Group has established a plastic bottle prototype and manufactures more than 200 prototypes every year to test the development of new containers.

Analyzing and evaluating the effect on content
Suntory Group’s unique standards are used to select container packaging following extensive testing and analysis. Using cutting-edge technology, we study and assess the composition of containers and packaging, as well as the influence of products on the contents, and confirm its safety.
In addition, we research and assess the effects of oxygen and light on the quality of the contents over time, which leads to the development of higher quality container packaging in collaboration with packaging material producers.

We confirm that the containers and packaging materials
do not contain any dangerous elements.
