Sealability
In today’s modern omni-channel retail environment an important factor in any packaging is that it can cope with a certain degree of rough handling and transportation. Thus it is important that any seals are strong and reliable. Aluminium foil containers offer ‘best in class’ sealing reliability over a number of formats and sizes and using a variety of lidding materials. The uniform conductivity of foil ensures sealing can be carried out at speed without the concern for inconsistent seal strength. Sealing and adhesion science has also enabled easy peeling to be achieved as well as the ability to cope with wide temperature ranges. So the seal can cope with frozen and hold its seal performance during cooking and until the consumer is ready to peel and enjoy the contents.
Case Study –Keeping Medical Devices Safe: A resilient container comprising ribbed alufoil plus lidding foil enables a drug delivery device manufactured by GlaxoSmithKline (GSK) to be extremely well protected from moisture ingress while holding it tightly to prevent damage due to impact or movement during distribution.
The design brief from GSK was for the development and industrialisation of a radically different method of containing, protecting, and delivering a vitally important inhalation device to the global market.
So the container manufacturer and its partners utilised their expertise in aluminium conversion technology and knowledge of the material’s packaging attributes to create a durable, very high barrier container based on a deep draw aluminium tray, with a consumer friendly peelable lidding foil.
We use aluminium containers for our product “Ofen-Fleischkäs” – ready to bake. It is a semi-preserved meat product, which is pre-cooked in our factory and only needs to be baked at the customer’s premises.
The container is ideal for this purpose. It is heat stable and the product can be both pasteurised and sterilised. In addition, due to its good barrier properties, it protects the product from external factors such as light and oxygen, ensuring the product characteristics are retained.
Compared to plastic packaging, aluminium offers many advantages, such as:
- No distortion at higher temperatures
- High consumer acceptance, as very easy to recycle
- A high-quality impression to the consumer
- Mechanical stability
