 Foods
Safety and Hygiene are the basics of all. Do you have cocking clothes
and other Linen sterilized properly?
Germany is said to have the Most Severe Regulations on Safety and
Environment in the world, where the laundries washing the Food and
Cocking linen are requested to have the RAL Certification.
In Japan, there are no comparable legally authorized hygiene regulations
on washing linen.
Hakuseisha has acquired the RAL-Quality and Test Regulations Certifications,
to supply the more Safe and Comfortable Linen. |

*peracetic acid : Though expensive,
its sterilizing power with high safety have good results in the
food bottle washing, also effective in cool water, and good for
textiles wear well.
(For linen, popular sterilizing methods are washing in high temperature
or with hypochlorite that heavily damages textiles to wear out soon.)
Hakuseisha applies peracetic acid to Sterilizer, preventing Contamination
in washing, pressing, packing and all other steps. |
