New resin blending brings cost savings
HOUSTON — A dozen in-line sheet manufacturers and thermoformers save by using a new resin grade, XK40, which is created by blending less K-resin. The supplier Phillips Chemical Co. hopes the processors may find more end uses for the material.
``We are selling less pounds while achieving the same level of performance,'' said Eddie Edmunds, market and applications development manager with Phillips' specialty plastics and specialty chemicals division in Houston.
Phillips began offering XK40 in mid-1998 as an extension of its 27-year-old line of clear K-resin styrene butadiene copolymers.
Typically, a processor of food packaging or disposable cups or trays substitutes XK40 for another K-resin grade and boosts the proportion of inexpensive general purpose polystyrene in the blend, Edmunds said.
The polystyrene level in an XK40 blend can be 15-30 percent higher than a KR05 blend or 10-15 percent more than a KK38 blend.
Phillips Chemical is a division of Phillips Petroleum Co.
House of Packaging buys Brown machine
CITY OF INDUSTRY, CALIF. — House of Packaging in City of Industry boosted its long-run thermoforming capacity with the July acquisition of a Brown Machine unit with a 30-inch-by-36-inch bed.
``A majority of the runs [on the new machine] are in excess of 100,000 pieces'' for consumable packaging moving through large-volume retail outlets and club stores, said Gene Giordano, vice president of sales and marketing.
Beds on four other thermoforming machines are no larger than 20 inches by 28 inches. Moving larger jobs has opened capacity on the other machines.
Thermoforming accounts for about 20 percent and paperboard folding cartons for the remainder of the firm's sales, which exceeded $25 million last year.
Family-owned House of Packaging employs 170 and occupies a 100,000-square-foot facility.
