Editing Packaging (section)

===Consumer package contents===
Several aspects of consumer package labeling are subject to regulation.  One of the most important is to accurately state the quantity (weight, volume, count) of the package contents.  Consumers expect that the label accurately reflects the actual contents.  Manufacturers and packagers must have effective [[quality assurance]] procedures and accurate equipment; even so, there is inherent variability in all [[Process capability|processes]].

Regulations attempt to handle both sides of this.  In the US, the [[Fair Packaging and Labeling Act]] provides requirements for many types of products.  Also, [[NIST]] has Handbook 133, Checking the Net Contents of Packaged Goods.<ref>{{Citation

Other regions and countries have their own regulatory requirements.  For example, the UK has its Weights and Measures (Packaged Goods) Regulations<ref>{{citation
