CO EXTRUSION PLANTS
RustXmanufactures VCI products on Hi Technology 3 layer and 5 layer Co – Extrusion plants . VCI products made on co-extrusion lines are proven to have low water vapour transmission rate and oxygen transmission rate. In a plastic film there are pores that are invisible which invite the moisture to pass through the film very easily. Normally in a 100 sq inch area or approx a 1 sq ft film of 25 microns made of LDPE, 2 gms of moisture pass through the film. Every time new moisture enters the film, it has to be neutralized by the VCI film. It is important for a low permeability especially for large sized bags to reduce any addition of moisture or oxygen / air in the packaged environment to reduce the working ability of the VCI chemicals.
