TECHNOLOGY | MATERIALS BOPP Thin glossy film cuts carbon impact
Innovia Films has developed Rayoface CSA46 – a clear, one-side gloss-coated BOPP film. The product is aimed at food and
beverage, household and personal care applications. The 46-micron film is around 10% thinner than most facestock films. This gives it a higher yield and reduces its carbon impact compared to thicker coated facestock films, says Innovia. Rayoface CSA film is a high clarity, low haze film giving enhanced product visibility and a ‘no-label look’ appearance.

ESD packaging for electronics includes corrosion protection
Cortec has developed a range of self-sealing bubble-wrap bags – offer- ing protection against both corrosion and electrostatic discharge (ESD).
ESD is a serious
problem in the electronics industry and can undermine product integrity. The new EcoSon- ic bags – based on Cortec’s Nano-VpCI technology – offer protection against ESD while also protecting against corrosion. The bags combine
vapour-phase corrosion inhibitors with self-seal cushioning bubble bags and ESD protection to safeguard sensitive electronics from three threats: triboelectric charge generation, corrosion, and physical damage. They protection metal components from

corrosion by saturating the enclosed airspace with vapour-phase corrosion inhibitors. These form a protective molecular layer on all packaged metals with- out leaving a noticeable film or residue. The bubbles add cushioning and physical protection.
O While ESD protection is
standard in the industry, corrosion protection is not. However, Cortec says that electronics components are

highly complex – and may contain multiple metal types in one unit. In dry environ- ments, the risk of corrosion is small – but when compo- nents are shipped over long distances, they can encoun- ter unpredictable and extreme environments. Good storage options can also be expensive and difficult to find in hot and humid climates where it is not uncommon for large computer companies to require climate-controlled warehousing for electronics. Combining corrosion protection with ESD packag- ing and bubble wrap tackles three threats at once for greater convenience and efficiency in electronics pack- aging. Any discoloration – or corrosion – on a component may cause the end user to reject it due to the possibility of failure, says Cortec. �

It has a wide print window and is suitable for printing with flexo, gravure, screen offset and letter press – as well as with UV, low-migration and water-based inks. “The performance of CSA46 means it
has excellent cold foil adhesion and appearance, allowing eye-catching graphics and label designs,” said Alasdair McEwen, product manager for labels at Innovia. “It provides balanced orientation for enhanced die-cutting and die lifetime and also has EU food contact compliance.” �

JSW OK for
TF-BOPE SABIC says that Japan Steel Works (JSW) has validated the use of its LLDPE BX202 material – a linear low-density polyethylene (LLDPE) for processing on tenter frame extrusion equip- ment for biaxially oriented PE (TF-BOPE) packaging film. The collaboration endorses the use of the material on JSW film lines, extends the machine supplier’s reach into BOPE film for flexible packaging. JSW has trialled the
material on a pilot film manufacturing line in Japan, to prove its perfor- mance. The material com- bines processability with good mechanical and optical properties. �
