Paraffined containers are characterized by an outer covering of glossy paraffin, and are made in various shapes. In some makes, the paraffin is forced into the pores of the paper base, making for added flavor-retaining and moisture-proof properties. In this type of package the label may also be printed direct on the package.
In recent years, vacuum packed coffee has won great favor, first in the West and latterly in the East. Tin cans are used. Vacuum sealing machines close the containers at the rate of forty to fifty a minute. Private tests by responsible coffee men are said to have shown that coffee in the bean or ground, when vacuum packed, retains its freshness for a longer period than when packed by any other method.
Labels
Coffee packers must give due attention to certain well defined laws bearing on package labels. Before the Federal Pure Food Act went into effect on January 1, 1907, many coffee labels bore the magic names of "Mocha" and "Java," when in fact neither of those two celebrated coffees were used in the blend. Even mixtures containing a large percentage of chicory, or other addition, were labeled "Pure Mocha and Java Coffee." The enactment of the pure food law ended this practise, making it compulsory that the label should state either the actual coffees used in the blend, or a brand name, together with the name of either the packer or the distributer. When chicory or other addition is used, the fact must be stated in clear type directly following the brand name. The reading matter on the label should contain facts only, and should not bear extravagant claims of superior quality or of methods of preparing or packing that have not been followed.
Coffee Packaging Economies
During the United States' participation in the World War, tin became practically unobtainable, and coffee packers turned to paper and fiber containers as substitutes in packaging nearly all grades. In this war period, commercial economy became a fetish in the business world; and coffee packers worked to save not only material, but shipping space, labor, and time. Paper and fiber containers proved to be not only practical but economical packages. Because of their war-time experience, many packers changed permanently to square and oblong containers. They found these containers could be packed "solid" in shipping cases, leaving no unfilled space between packages as is the case with cylindrical cans; also, smaller shipping cases could be used. As a further measure of economy, several packers changed from the square "knocked-down" paper or fiber carton to the oblong carton that is made up, filled, and sealed by automatic machinery from a flat, printed sheet of cardboard. This type of container is generally lined or wrapped with a moisture-proof and flavor-retaining paper.
There has been a tendency in recent years to standardize coffee packages as a means of working out packaging and shipping economies. One of the leading American proponents[336] of standardization said:
One of the first arguments raised against standardization is that it eliminates individuality, and individuality is one of the big guns covering the front line trenches in the war of competition. The folly of recommending that every one-pound coffee carton, for instance, should be of exactly the same size and shape is immediately apparent; but let us not confuse such unification with standardization.
Assuming that a pound of coffee may be safely contained in seventy-two cubic inches, we find that a carton three inches thick by four inches wide by six inches high will serve our purpose; and, as an illustration of extremes, a carton three inches thick by three inches wide by eight inches high, or one [carton] two inches thick by six inches wide by six inches high, will each have exactly the same cubical contents. In fact, there is an almost infinite variety of combinations of dimensions which will contain substantially seventy-two cubic inches.
As an example of how coffee packages can be standardized this authority cites the following sizes of flat-sheet containers and their respective dimensions and capacities:
