Introduction
1. Through the years, packages have developed from gourds, large leaves, and other containers found in nature into a group of mass-produced containers that are frequently formed from synthetic materials.
In the early 1900’s, most products were delivered to customers in basic containers such as barrels, boxes, jugs, bags, or wrapping paper.
Since then, the vast assortment of new containers that has been developed includes:
microwaveable pouches aseptic cartons

measuring and filling the product closing or sealing the container applying a label
Checkweighing inspecting
preparing the individual packages for shipment

Packaging lines are made up of groups of packaging machines in much the same way that the machines are constructed ponents.
