Pleural effusion is an abnormal, excessive collection of this fluid. There are two types: Transudative pleural effusion is caused by fluid leaking into the pleural space.

A retort pouch is a type of food packaging made from a laminate of flexible plastic and metal foils.It allows the sterile packaging of a wide variety of food and drink handled by aseptic processing, and is used as an alternative to traditional industrial canning methods.his multi-layer structure prevents the retort pouch from being recycled into other retort pouches or food packaging. However, the material can be recycled into an aluminized resin or up-cycled into textile materials.
The second phenomenon to consider is the heat transfer process. In retort containers, after the heat passes through the container via conduction, it can heat the food in two ways. Conduction is appropriate for solid pack foods such as pumpkin and dog food, or for foods with solid particulates.
