Pregis Corp. says it has taken hybrid cushioning (HC) to a new level with the launch of HC Renew™. The product is a high-performance, low-density polyethylene film that contains a proprietary organic additive that Pregis says accelerates microbial biodegradation, without compromising recyclability. HC Renew also contains up to 10% recycled content.

Pregis’ hybrid cushioning differs from traditional void-fill pillows because it features multiple, smaller air chambers versus one larger cushion. Flat, perforated rollstock is mounted onto the company’s AirSpeed® HC™ unit, which creates the rows of small, air-filled pockets by transferring air into the individual chambers. This creates a cushioning structure that is stronger than traditional single-cell pillows, making it suitable for more rigorous applications.

HC Renew does not contain any heavy metals or salts, can be transported in high heat, and has a longer shelf life than starch-based degradable products, Pregis says. HC Renew film is tinted green using an organic colorant to provide consumers with a visual cue.

The material will not begin to biodegrade until it is disposed of in a microbe-rich environment, such as a landfill. Complete biodegradation typically occurs within one to five years, depending on conditions. HC Renew is ASTM D5511-compliant.

Three different cell heights are available: ¾, 1, and 1¼ in. The film is also available in pre-perforated lengths of 6-in. (small and medium cell sizes) or 7-in. (large cells) increments, depending on application requirements.
