Film drapes Sengewald in success

Appearance, tear resistance, and peel properties are key benefits of a top film web used by Sengewald in Germany for thermoformed packs of surgical drapes and gowns.

A new HDPE top film web provides several benefits for Sengewald Klinikprodukte's packaged surgical drapes and gowns.

Last year, Sengewald Klinikprodukte GmbH & Co. KG, a manufacturer of surgical drapes and gowns, began to improve its packaging material for commercial shipments of its thermoformed/

filled/sealed sterile medical products with a new top film web from Rollprint Packaging Products that delivers a bevy of benefits compared to a previous structure. Among the benefits are better peel properties, appearance, handling, and tear resistance.

Sengewald had used a top web of coated special medical paper and a bottom web of nylon-polyethylene peel film. The paper web didn’t provide the tear resistance sought by the Rohrdorf, Bavaria, Germany-based firm.

“We had the goal of replacing the paper web with film [to gain] the necessary properties,” says Wolfgang Spindler, research and development manager at Sengewald. “We wanted better peel properties, more comfortable handling, and puncture and tear resistance.

“This new packaging [also had to] have a high break strength and be extremely elastic,” he says. “A critical requirement was [that it had to have] great puncture resistance, as well as an attractive appearance. The peel ‘behavior’ should be even, and the film must not break during the peel process,” adds Spindler.

Enter the solution

Sengewald sought a solution through a previously announced strategic partnership with Rollprint and Pactiv’s “sister” company Kobusch-Sengewald, in Germany.
