Behold! The innovation has remained the world’s first-ever pasteurizable lightweight pet bottle for beer with a non-petaloid base.
Subsequently, more and more beer producers are starting to realise the many benefits of switching from glass to PET packaging. Not only can PET bottles maintain the appearance and stability of a glass beer bottle, but they are up to 86% lighter.
For manufacturers, this novel development means significant improvements in supply chain performance and their sustainability profile, plus lower production costs.
In terms of the stability and appearance of glass, the unique design of the PET beer bottle is suitable for flash and tunnel pasteurised beer, as well as micro-filtrated beer.
The PET beer bottle also incorporates a crown cap and non-petaloid (champagne) base; and it can withstand pressure of 20 PU in the tunnel (standard for lagers). The PET beer bottle, which weighs just 28gram, maintains a stable base after pasteurization, besides enabling design flexibility.
A six-month shelf life
When packaging beer, it is critical to prevent oxygen entering and carbon dioxide escaping the package. The new PET beer bottle design achieves this with different solutions, such as single-layer material blends and Sidel’s proprietary Actis™ gas-barrier technology. As a result, the bottle can protect beer qualities for up to six-months.
Tested and proven
The PET beer bottle has successfully undergone full industrial production tests to prove its performance, both during production and across simulated supply chains. These tests include advanced packaging optimisation and qualification tests; Finite element analysis and feasibility testing; Stability evaluation. Other are Liquid quality protection Rigidity testing.
Sidel packaging experts have blown a 330 millilitre version that can achieve a six-month shelf life (with less than 1 parts-per-million (ppm) of oxygen ingress and less than 17% of carbon dioxide loss). We can also provide versions up to 600 millilitres and are continuously developing even larger sizes.
