and recyclable packaging is becoming increasingly important. This has led brand owners and players in the packaging industry to switch to sustainable materials such as recyclable mono-materials and to packaging processes that have been designed precisely for these materials.
This is a switch that is challenging to implement, especially in the packaging of chocolate products. Two traditional methods of effectively packaging sweets are outlined below.
A variety of bars are packaged using composite materials, e.g., a base of plastic or paper in combination with an aluminium layer. The products can be easily packaged by fold wrapping and do not require any additional securing of the packaging by sealing or glue. However, packaging materials made of composite materials are not recyclable and are not sustainable in view of market developments. It therefore makes sense to switch to the use of recyclable mono-materials for packaging processes. However, these materials have poor dead- fold properties, so the packaging must be closed and fixed after folding by sealing or with the aid of glue so that it cannot open again.

Theegarten-Pactec’s innovative technology offers numerous advantages: Material costs can be reduced by eliminating the need for aluminium laminate to dissipate heat and protect the chocolate.
For well-known brand products, a second packaging variant is traditionally used: a combination of two packaging materials – aluminium paper laminate and plastic packaging. This first “packaging layer”, the inner wrap of aluminium paper laminate, is required as a barrier to protect the sensitive wchocolate products during the actual packaging process. When closing the outer wrap using contact sealing technology, the chocolate could otherwise be damaged by the heat that is generated or by the sealing tools used.
As an alternative to this process, packaging has been glued with hot melt. The packaging specialists at Theegarten- Pactec have now developed a technology called “suction supported sealing”, which offers numerous advantages over these conventional processes. Continues over...
