Avient Introduces Gravi-Tech™ Polymer Metal Composites for Luxury Packaging

On October 18, 2021, Avient Corporation announced the introduction of new Gravi-Tech™ density-modified thermoplastics that enable advanced metal plating finishes to provide the look and feel of metal in advanced packaging applications
.

To meet the growing demand for metal alternatives in the luxury packaging industry, the expansion of the product portfolio includes 15 grades suitable for electroplating and physical vapor deposition (PVD) processes
.
These high-density materials offer the ability to create a variety of enhanced metal surfaces for added visual appeal, representing high quality and high value
.
In addition, these materials offer the design freedom and manufacturing ease of thermoplastics for applications such as luxury caps, caps and boxes
.

“These metallizable grades offer high-end packaging manufacturers an easier way to incorporate the luxurious look and weight of metal into their products
,” said Matt Mitchell, global marketing director of specialty engineered materials at Avient.
“Our densities The combination of modification technology and metal coating gives customers more design freedom, enhances the sensory experience, and saves time and costs
.
”

Designers face various processing challenges and design constraints when designing with metals such as aluminum, zinc, iron, steel, and other alloys
.
Injection-moldable Gravi-Tech can help designers achieve evenly distributed weight, complex designs and visual finishes in metal without the additional costs and steps associated with die casting molds or secondary assembly operations
.

The new Gravi-Tech grades are available in polypropylene (PP), acrylonitrile-butadiene-styrene (ABS) or nylon 6 (PA6) formulations with similar densities to traditional metals
.
The five new electroplating grades have specific gravities ranging from 1.
25 to 4.
0, while the ten PVD grades have specific gravities ranging from 2.
0 to 3.
8
.
They have excellent scratch resistance, adhesion and chemical resistance
.

These metallization compatible grades are available globally to meet the weight, finish and performance requirements required in a wide variety of weight packaging applications
.
Many grades also meet U.
S.
Food and Drug Administration (FDA) requirements for food contact
