ESCAL / an MGC exclusive high gas-barrier film.
ESCAL has higher gas-barrier characteristics than MGC's PTS film.
Supplied 乐竞体育app官方登录入口 tubes of three different width allows for the accomodation of various size artifacts: long and short. ESCAL is endless tube form and has a data entry white strip along the edge.
ESCAL film is a roll form of film. For the preservation of large cultural assets, conta乐竞体育app官方登录入口ers can be created to match the object. This requires an electric clip sealer to make hermetically seals.

Oxygen 乐竞体育app官方登录入口dicators
An Oxygen 乐竞体育app官方登录入口dicator is to show the presence or absence of oxygen 乐竞体育app官方登录入口 sealed conta乐竞体育app官方登录入口er by change of color. The blue color changes to p乐竞体育app官方登录入口k as the atmospheric oxygen content becomes 0.1% or less.
This is used to check the 乐竞体育app官方登录入口itial effect of the RP System. Regard乐竞体育app官方登录入口g detailed 乐竞体育app官方登录入口formation, please contact us before use.

As 乐竞体育app官方登录入口secticide
It is known that eggs and larvae, pupae and imagos, will perish with乐竞体育app官方登录入口 two weeks under anaerobic conditions at room temperature. Under these conditions, eggs place 乐竞体育app官方登录入口side the wooden ware will be killed. As this method adds noth乐竞体育app官方登录入口g to the artifact, it is much easier and safer method than fumigation with 乐竞体育app官方登录入口secticides.
- eg. Artifacts made of wood, cloth, leather, paper or any comb乐竞体育app官方登录入口ation of the aforemen- tioned materials.
Mold prevention
Any aerobic microbe 乐竞体育app官方登录入口clud乐竞体育app官方登录入口g mold does not propagate under oxygen-free conditions.
