FUNCTIONS OF PACKAGING

1. Containment (Unit size): To secure the item from loss or damage if the package breaks open. For instance, carton, pallet.
   
2. Protection: To protect the package from damage or loss. For instance, moisture, insects.
   
3. Apportionment: To break bulk the bigger unit size to the smaller unit size to suit to customer needs.
   
4. Unitization: To unitize smaller unit size to bigger size for the ease of handling. To ensure the efficient use of storage facilities and transportation vehicles. For instance, palletizing cartons into a pallet.
   
5. Convenience: To allow the customers to use the products with the least effort.
   
6. Communication: To convey any important messages or characteristics of the product to be taken note of. Also, to identify the product.

These will help in reducing costs in terms of:
- reduce the chances of damaging the goods
- save space (more amount of products in the same amount of space)
- reduce on the number of transport journeys (can put more products on one trip)
- durability
- recycling
