Corrosion solution company Cortec is offering two kinds of barrier paper, both of which is says are USDA Certified Biobased Products and are available in Australia and New Zealand.
The company says that the first type, EcoShield Barrier Paper, offers basic barrier protection with a coating that resists water vapour, grease, and oil. It claims that its water vapour transmission rate (WVTR) makes EcoShield Barrier Paper a competitive alternative to polycoated paper and superior to waxed paper. EcoShield Barrier Paper contains 65 per cent USDA certified biobased content and passes the US FBA’s repulpability testing and EU recyclability testing. Potential uses include, but are not limited to, barrier packaging, surface protection on workbenches and moisture resistant bands and tags.
The second offering is EcoShield VpCI-144, a barrier paper which the company says is designed specifically for metals protection. In addition to its barrier coating, EcoShield VpCI-144 is coated with vapour phase corrosion inhibitors that form a protective molecular layer on surfaces of metal components wrapped inside the paper. The company says this presents dual protection against corrosion: first by inhibiting the ingress of corrosive moisture and vapours; secondly by interfering with the natural corrosion reaction of any moisture and oxygen that does find its way into the parcel.
Such protection is ideal for situations where metal parts will be shipped or stored in a humid environment. It is also a potential solution for components covered with grease or process oils that must be left in place for one reason or another. The barrier coating discourages the moisture or grease from breaking through the paper, thus allowing the vapour phase corrosion inhibitors to continue doing their job in an enclosed environment. EcoShield VpCI-144 contains 69 per cent USDA certified biobased content and also passes the US FBA’s repulpability testing and EU recyclability testing, claims the company.
