Chemical manufacturers around the world have devoted considerable effort to adopting the globally harmonised system (GHS) of classification and labelling of chemicals.

A new label stock, made from its proprietary Teslin substrate, that is engineered to make that job a little easier - PPG Teslin label stock, was introduced by PPG, a global manufacturer of coatings, paints and speciality materials.

What is Teslin substrate?

Manufactured exclusively at PPG’s plant in Barberton, Ohio, USA, Teslin substrate is a polyolefin-based synthetic paper. Although it was introduced in the early 1990s, Teslin substrate remains unique in the industry due to its microporous structure, which produces a combination of printability, durability and security benefits that other printable synthetic substrates cannot match, making it one of the most widely used synthetic papers on the labelling market.

“We had the goal of creating a substrate with the same printability features as pulp paper, along with the ability to outperform existing synthetics and films in the marketplace,” said Jason Depner, PPG global segment manager, Teslin products.

“Teslin substrate is a durable, secure and highly printable synthetic paper that excels in applications that demand a tough, high-performance material.”

To help chemical manufacturers and other shippers of hazardous materials take fuller advantage of these benefits, PPG recently launched Teslin label stock, a  new portfolio of durable, printable and secure label stock, including a British Standard (BS) 5609-certified label stock for GHS-compliance that combines the paper with high-quality label adhesives and liner materials to create a dependable, economical, versatile and worker-friendly solution for chemical container labeling applications.

“Teslin substrate has always been regarded as a premium face stock because of its durability, print versatility and ability to secure printed data,” Depner added. “We developed this supply option to ensure all regions of the globe have ready access to Teslin label stock so we can better meet our customers’ needs.”

The benefits of microporosity and why they matter

Teslin label stock is unique among synthetic label stocks such as vinyl, polyester and polyproylene for one reason: microporosity.Formulated with a polyolefin-silica matrix, Teslin substrate contains millions of micropores that absorb inks, toners and adhesives, locking them into its structure for long-lasting durability. As a result of this exclusive characteristic, Teslin substrate offers end-users performance benefits that other synthetic stocks cannot replicate.

Print versatility

One distinguishing characteristic of Teslin label stock is print versatility. Teslin label stock accommodates a wide range of print technologies, including high-temperature and digital colour printing processes such as a laser, inkjet and thermal transfer printing. Most synthetic papers are only compatible with a limited number of print processes and require corona treatment, sapphire or other types of the coating before they can be digitally printed.

The exceptional pairing of versatility and print-readiness provided by Teslin label stock enables chemical manufacturers and shippers to accommodate printing of variable data on-site and to quickly and cost-effectively implement on-demand printing of colour-coded GHS-compliant labels using the in-house equipment.

Static dissipation

The build-up of static electricity during the drum label printing and application process is a phenomenon in chemical manufacturing plants and is particularly dangerous due to the presence of solvent vapours in these environments.

“Many people don’t realise it, but PVC and PET labels are often vulnerable to build-up of static between the face stock and the liner when used in low-humidity environments,” said Depner. “When labels are processed through laser printers, they are charged through an electrostatic process that causes print toner to adhere to the label surface. When printed, labels are peeled, the action can inject a static charge into the workspace, threatening to combust a dangerously flammable environment made even more hazardous by the presence of chemicals, solvents and materials with low flashpoints.”

Unlike other synthetic label stocks, the micropores in Teslin label stock absorb and dissipate static build-up. The end result is significantly reduced potential for electrical discharge and arc-flash-related fires, and inherently safer workers and workplaces.

Durability

While the microporous surface of Teslin label stock makes it pliable, absorptive and versatile enough for any label application, the presence of polyolefin polymer in the formulation creates an exceptionally tough material.

In addition to being waterproof, Teslin label stock is resistant to chemicals, solvents, tearing and extreme temperatures, all characteristics that enable it to achieve GHS-compliance and to meet BS 5609 Section 2 and Section 3 durability specifications for hazardous good shipped over international waters.

“If the shipment is classified as hazardous goods and shipped over international waters, we have attained the required BS 5609 certifications that enable our customers to take advantage of our label,” Depner said.

Built-in security of printed data

Because its micropores quickly absorb inks and toners, Teslin stock also provides built-in security in two ways that nonporous substrates such as vinyl and PET polypropylene cannot.

The first is that, by locking printed material into its structure, Teslin label stock protects shipping data from scrapes, scuffs and other types of damage caused by exposure to weather and handling with no additional processing or expense. With other synthetic labels, printed data merely sits atop the surface of the substrate, where it is vulnerable to abrasion and other hazards.

The second is through Teslin label stock’s ability to permanently distort if the alteration is attempted, which makes it both tamper evident and tamper-resistant.

Supporting all industry-standard label conversion techniques, including rolls, pin-feeds, die-cuts, sheets, fan-folding and more, Teslin label stock is available in four standard configurations, including general purpose permanent; general purpose removable; ultimate bond and BS 5609-certified, on-demand printable for GHS compliance. It also can be custom-designed to meet the demands of a specific application. Teslin substrate also aids worker productivity by providing the quick, easy and bubble-free application to products and containers.
