  • Testing Laboratory

    Testing Laboratory

    In order to improve the quality of our pulp mould products, we have established a testing laboratory where we perform a variety of tests, such as strength and drop testing.

  • Mould Cleaning Room

    Mould Cleaning Room

    The metallic mould is the heart and soul of the pulp mould product. Each production plant is equipped with a mould cleaning room where the metallic moulds are scrupulously cleaned and maintained.

  • Foreign Matter Imaging Detector

    Foreign Matter Imaging Detector

    This device detects foreign matter adhering to raw materials. It is used on pulp mould production lines and relies on image detection to spot foreign matter.

Plastic Film

We have developed operating procedures which our employees scrupulously follow regarding the management, correction and maintenance of inspection, measurement and testing equipment so that we can ensure consistency in product supply and quality to customers.
The following are some key examples of how this is put into practice.

    This device uses a camera to detect defects in plastic film, recording and mapping any which are found. It is used on all plastic film and T-die embossed film production lines.

  • Non-contact-type Thickness Gauge

    Non-contact-type Thickness Gauge

    This device automatically measures, records and graphs film thickness. It is used on the production line for T-die embossed film.

  • Autograph


    This equipment is used to measure film tensile strength, elongation, peel strength and coefficient of dynamic friction.

Heavy Duty Bag

Our top priority is providing customers with safe and reliable products - a goal towards which we apply our many years of accumulated experience, data and know-how. Furthermore, we employ a food management safety system(*) to ensure consistently stable quality.
For us, customer satisfaction is inextricably linked with product quality. Thus, our highly experienced technical staff as well as production and sales staff work as one to fastidiously satisfy a diverse array of customer requests.
