About Handling

  • 1. As a packaging film, use a material that is not easily permeable to oxygen.
    Oxygen permeability: 200ml/m2·24hr·MPa or less

    2. When opening the cardboard box, refrain from using a cutter knife. The products inside may be damaged.

    3. After opening the cardboard box and before taking out the products, if there is any swollen outer packaging bag when unopened, avoid using it because there is a possibility of pinholes or poor sealing (normally they are in a deaerated state)

    4. Open single packets from the notches on respective outer packaging bags.
    However, since the packet is filled up to the bottom of the notch, make sure not to break it when opening.
    The starting portion of a continuous strip of packets (Z-fold) is clearly indicated by a sticker affixed to the outer packaging bag.
    After opening, start using from there.

    5. After opening, use within the working time of the corresponding grade.

    6. In short-time situations, such as a break time, clip-on storage is also possible (deaeration sealing is preferable).

    7. Storage method
    Other than ZS-C: Avoid direct sunlight and sudden temperature changes, and store in a dark place.
    ZS-C: After product arrival, store the product in a refrigerator (10°C or lower dark place).

    8. The deoxygenation speed of Negamold®Z slows down with decreasing temperature.
    9. If Negamold®Z and inert gas are used in combination, avoid using carbon dioxide.

    10. Combined use with vacuum packaging may cause Negamold®Z to stick to the food and packaging film, making deoxygenation and Ethanol evaporation impossible.
    Keep deaeration to such a light degree that air circulation occurs in the package.
