The product should be accessible from the container.  For instance, spouts for pouring liquid and zip seals for reuse.

Examples of secondary packing are corrugated boxes, trays and bags. Tertiary packaging consists of pellets, and wooden boxes. 

Special techniques 

Special techniques are used for packaging food. As oxygen in the air oxidises the food and makes it putrid, this is removed by either complete vacuum or partial vacuum. Alternatively, the air is replaced with an inert gas like Nitrogen.
