Introduction
1. What a filler can be asked to do?
Fillers, filling machines, are used to transfer many types of products from bulk storage bins and vats into the containers in which they find their way to the market. The great variety of products that are packaged and the containers that they fill has caused the development of a large number of processes, techniques, and machines that are used for product filling.
2. Considerations in selecting a filler
Types of products: from very thin liquids to semi-liquid products, pastes, and solids; stable, volatile, explosive, hot, frozen products.
Size, shape, and construction of the containers: glass bottles and jars, plastic bottles and cartons, paperboard boxes, metal cans, and plastic or paper bags.
Way the product is measured: by volume, weight, or count.

Desired speed of the operation: a relatively slow manual operation, semi-automatic, fully automatic ( high speed lines)
Special handling requirements of the product

Liquid Filling
1. Introduction
Liquid products: alcohol and soda water
Semi-liquid products: toothpaste, peanut butter, and pound

2. Types of Filling Machines
The containers may be made of plastic, metal, glass, treated paperboard, or a number of other materials.
The shapes of the containers include those of bottles, jars, vials, tubes, cans, pouches, cartons, and drums (Figure ).

Liquid Filling
Most liquid and semi-liquid products are filled by one of two major methods: volumetric, or constant level filling.
In volumetric filling the amount of product is premeasured so that each container has the same volume of product.
