Business introduction

Films refer to thin polymer membranes. They are produced from a wide variety of materials. Our plastic film products are discussed here.

Countless film-based items used in our daily lives, such as snack bags, packages of cup ramen, aluminum bags for tea, wrapping films for household use, and plastic shopping bags. Especially in food-related applications, films boost convenience and enrich our food consumption as their performance improvement leads to enhanced food preservation and enables retort food that can be eaten right after heating.

Aside from film thickness, all types of films appear identical, but they have different functionality depending on the purpose. Take for example disposable hand-warmers, which give off heat triggered by oxygen in the air. They are covered with moisture-permeable waterproof film with fine holes that allow oxygen to pass through. Their outer bags, which are not opened until usage, are made of oxygen barrier film, which is widely used for food packaging as it prevents food deterioration due to oxidization. Our array of products includes both moisture-permeable waterproof films and high performance oxygen-barrier hybrid coating films. Polyolefine heat-shrinkable films, which shrink when heated, are used in packaging applications for cup ramen and other goods. We offer a wide variety of shrinkable films in accordance with the customer's request. Especially KOHJIN-KORAP™(PP Shrinkable films) is for high-speed packaging use, and is a high-quality films suitable for full-color gravure printing and hold the largest share in this market in Japan.

In 1964, we established a unique manufacturing technology called the tubular simultaneous biaxially oriented film production method. Positioning it as a core technology, we develop and manufacture films with varying functions. We will continue our research and development on films that enhance your lifestyle.
