Container lightweighting has become an increasingly important part of the sustainable packaging toolbox. Here Peter Tindale, International Sales Director at Selig Group, a global leader in container sealing and venting technology, looks at the relationship between lightweighting and induction heat sealing and how, thanks to a new liner, industrial producers can reduce material usage and save even more money too.
Induction heat sealing and lightweighting – the perfect match
Lightweighting sounds good in practice, as who doesn’t want to reduce material and freight costs, meet lower GHG goals and save money? However, thinner packaging can lead to performance issues and increased spoilage levels. And this is where induction heat sealing comes into its own.
Induction heat sealing technology has long been part of the packaging mix for producers looking to deliver tamper-evidence, container security and shelf-life optimisation. However, thanks to the hermetic seal created when an induction heat seal liner is used, the container and closure can both be made structurally lighter, without compromising the item’s integrity or leak performance.
Taking an example from the UK dairy sector, over the past decade or so a 37% reduction in plastic has been achieved in every plastic milk bottle, thanks to the use of induction heat sealing. It isn’t only in the FMCG sector either. Companies such as Castrol have garnered press attention in the industrial sector, with significant plastic reduction thanks to the combination of container redesign and induction heat sealing.
New industrial grade liner
To help more and more industrial producers make the most of the benefits of lightweighting, Selig has announced the launch of its new Safe-GardTM Industrial liner. This multi-layer barrier liner has been optimised for use in industrial applications, and offers producers a cost-effective, hermetic seal to PE containers.
Safe-GardTM Industrial has been designed to seal both aggressive and non-aggressive contents in agricultural, institutional, cleaning, pet and motor care applications and more. It features a robust material in the liner that provides an increased tolerance to higher temperature storage, compared to the original Safe-GardTM liner. The two piece pulp backed heat induction foil innerseal creates a weld seal with PE containers, and enables high performance and protection for even the most challenging contents.
The liner is a non-food compliant version of Selig’s industry leading Safe-GardTM two-piece liner. It enables producers to access all of the benefits of the original liner, including leak prevention, tamper-evidence, on-liner branding, shelf-life extension and packaging lightweighting, but all at a lower price point. Similar to Safe-GardTM, the liner materials are easy to use and can be glued into the cap or inserted behind the retention feature, without any changes to existing cap designs.
By adding this Safe-GardTM Industrial liner to the range, Selig Group offers industrial and chemical users a more cost-effective sealing and lightweighting solution that still delivers required levels of performance. Industrial producers now have even more ways to achieve peace of mind regarding container integrity, security and consumer convenience at a very competitive price point.
