YUPO Super-Fast Dry FRBW110 Used for Premium, Water-Resistant Overwraps for Natto Packaging

Case Studies

Delivering a commitment to quality to the dining table through premium packaging

Inaba Natto Co., Ltd. faced issues with wrinkling and texture deterioration caused by moisture and condensation in natto overwraps. YUPO Super-Fast Dry FRBW110 was selected for its water resistance and premium appearance, helping maintain visual quality throughout distribution.
Inaba Natto Co., Ltd. has adopted YUPO for overwraps used in its natto products, which are distributed under refrigerated conditions and consumed in everyday settings. With over 100 years of traditional natto production, the company required packaging that conveys value not only through product quality but also through its appearance.
Material selection focused on water resistance against condensation and moisture, along with a premium appearance and the ability to maintain these qualities throughout storage and distribution. Maintaining visual appeal was particularly important for products handled daily by consumers.
YUPO Super-Fast Dry FRBW110 was selected for its resistance to moisture-induced wrinkling and its ability to maintain a stable appearance. Compared to conventional paper, it enables both shape retention in refrigerated environments and a premium finish, which led to its adoption.

Customer Feedback

We have continued to produce natto with care, adhering to traditional methods. Because natto is always stored under refrigeration, we were concerned about packaging wrinkling due to moisture and condensation. By using YUPO overwraps, the packaging remains smooth and maintains a clean appearance, and we are very satisfied with the final result.
