& Greaseproof Mfrs. Assn, and the Vegetable Parchment Mfrs. Assn,

Membership rolls of these associations reveal that most suppliers are concentrated in the East or Midwest, although there are many waxed-paper plants in the South and West. Among waxed-paper companies about a dozen are reported to do 90% of the business; 100 others serve small-volume needs. In the other paper-wrap groups a dozen companies make up the bulk of the business. The bigger companies have multi-plant operations to serve customers on a national basis.

The biggest single volume of business goes into bread wraps. An estimated 75% to 80% of white bread is wrapped in waxed papers. Because white bread accounts for perhaps 85% of the total bread market, waxed papers may be found on about 28 million of the 41 million lbs. of bread baked daily.

In addition, transparent bread wraps often use an inner waxed-paper band which, in the last two years, has tended to become more common as more stress is put on brand identity and appetite appeal. Also, these paper bands are being made increasingly wider for better display. In 1957 the bread-baking industry accounted for around 235 million lbs. of waxed paper, with a total worth of almost $71 million.

The package

History is on the side of paper wraps. Among packaging's pioneers were the first boilable, the first transparent and the first heat-sealable flexible wrap-”all made of paper.

Vegetable parchment, the earliest boilable paper, was first made in this country in 1885, although the British had been manufacturing it a quarter of a century before. In the U.S. its earliest use was protecting tub butter.

Waxed paper, particularly glassine, early approached transparency and it was heat sealable. Lacquer-coated glassine, boasting transparency and heat sealability, was introduced at the first Packaging Show 27 years ago.

Perhaps the country's first waxed paper was made in 1877 by a New York candle maker who dipped paper into tallow to wrap fish and carry it home. Subsequently, he went into the business of commercially producing such a sheet and one of his first customers was Huyler Candy Stores of New York for wrapping candy in waxed paper.

String-tied waxed paper around bread first ap-pered in the 1890s. Heat-sealing waxed paper came in 1911, followed shortly by converted waxed papers. By 1920 Cracker Jack and Wrigley's Chewing Gum were sales successes due partly to their freshness in glassine and waxed paper wraps.

Wraps can be used for protection, merchandising

Vegetable parchment manufacturers have a major market for this grease-resistant paper in wraps for butter and similar food products. This four-color holiday design against the white snowflake background demonstrates its printability.

appeal or both. Depending on product shape and package function, packagers may choose from among three basic types: single wrap, including twist, which is the product's only protection at retail; overwrap, which sheathes another package, such as a carton, and unit wrap, an inner protection also used with another package. Graham crackers, for instance, use both an inner wrap and an overwrap. Only a small portion of packagers use the twist technique, most of this going into the confection field for "kisse-¯ and similar candies.

Among the big users of paper wraps are manufacturers of cereal, bread, candy, chewing gum, biscuits, ham, crackers, butter, soap, tobacco and frozen foods.

For such customers a supplier can provide papers or combinations of materials that are opaque or translucent, heat sealable or not, dry or waxed, in one or more plies, embossed or smooth and in almost any color needed. The microclimatology of the package its characteristics related to the biological and physical properties of the product inside determines the type and weight of paper to be used.

Among the qualities that can be built into paper wraps are grease resistance, high wet strength, opacity, water-vaporproofness, mold resistance, flame resistance, infestation resistance, high impact and tear strength, and corrosion preventiveness. Papers may also have release properties, scuff resistance, high gloss, blocking resistance and heat sealability. And they can be non-toxic, odorless, tasteless and have specific pH values.

Protective coatings to help impart some of these qualities can be grouped under four types: (1) hot melts, such as microcrystalline waxes and paraffin waxes; (2) solvent coatings, such film-forming resins as ethyl cellulose and polyvinyls; (3) emulsion coatings, Including rubber latices and resins in aqueous emulsions, and (4) such extrusion coatings as polyethylene.
