What are different types of sealing that can be done in VCI package?
A. CAPRUST films require heat sealing for better results. Smaller bags may have their openings simply folded over, stapled or taped shut. Larger bags, for example those used for automobile engines, may be closed off with a tie wrap or heat sealed. CAPRUST bags used as liners for large wooden crates or corrugated cardboard cartons may simply have their openings folded over, it would also be advisable to vacuumise the bag. In all cases the main objective is the same a) to ensure that any air entering the interior of the bag comes only through the sides of the bag and b) all traces of VCI disappear from the surface. Basically impulse heat sealing process is used to seal the bags and big covers are being seal by manual bar heat sealing process.
