Fruit, vegetables, meat or flowers packed in transparent materials like cellophane or polyethylene film . . . can be kept under refrigeration without any fog appearing on the inside of the container. The trick is done by using surface ac­tive chemicals. Atlas SPAN® 40 (sorbitol monopalmitate) and TWEEN® 85 (polyoxyethylene sorbitan trioleate) are often called on for this purpose. The manufacturer of the packaging material applies the Atlas chemical to the surface of the film, or includes it directly in the sheet. Because it is surface active, the Atlas chemical reduces the surface tension of water that may condense on the film. Thus, -water cannot accumulate in drop­

lets that would give a foggy appearance . . . but spreads out evenly instead. You can demonstrate this principle by dropping a big globule of water on a surface. If you touch it with barely enough surfactant to cover a pinhead, the globule will immediately spread out flat. The higher the spreading coefficient value of the surfactant, the greater is its ability to do this trick. SPAN and T W E E N products are adaptable to various types of films .. . the choice depending on specific require­ments for odor, taste and noa-toxicity. For copies of the applicable patent on this subject (Wingfoot Corporation, Patent No. 2,561,010), write or call Atlas today.

T h e manufacturer of an automatic machine which can turn out thousands of individual raw meat patties per hour has saved $15 per unit in the manu­facture of his new model, through use of an Atlas polyester resin, ATLAC 88£. Important parts of the machine, includ­ing the hopper and gear-driven com­pressor rollers, were redesigned to be made from reinforced plastic based on ATLAC 382, instead of from cast metal. Xhis eliminated expensive machining, welding and forming of metal parts, a n d reduced cos t s of both labor and parts.

According to a recently published article o n the patty-making machine, the factors leading to the selection of this ATLAC 382 plastic over several other types of thermosetting materials were i t s combination of low weight and high strength, dimensional stability and excellent flow characteristics. Further, the superior resistance of ATLAC 382 t o meat juices, washing detergents and many other chemicals made it a natural choice for this particular use.

"We'll be glad to send you a reprint of "the article, showing details of parts and molding technique. A bul let in on ATLAC 882, giving properties and chemical resistance data, is also yours for tbe asking. Samples are available for your own testing, of course.

Flexible, non-breakable containers of poly­ethylene have become increasingly popular

for packaging a variety of products. However, certain ingredients and formulas packed in this type of bottle may cause tbe container to deform in storage. Atlas research chemists are interested in this problem, because many manufacturers use polyethylene containers for products that incorporate Atlas emulsifiers. A series of tests has been made in our laboratories on the effects of various ingredients, emulsifiers, and types of emulsions on the stability of such containers. We found that properly formu­

lated oil-in-water emulsions do not affect the container, but that water-in-oil preparations often cause bottle deformation. To get a compilation of the results of our tests, just write to Atlas for a copy of the article, "Cosmetic Emulsions inPolyethylene Containers," by Phyllis J. Carter and William C. Griffin. Even if you aren't in the cosmetics business, you'll find much useful data on tbe selection of materials and ways to test products that you're packaging this way.
