Plastics closure merger as Portola closes on Integra-Seal

Plastic closure processor Portola announced its pending acquisition of fellow closure molder and neighbor Integra-Seal Industries LLC for an undisclosed amount. The sale is expected to close by the end of this month. The purchase gives Portola additional mans to market closures to small- to medium-sized dairies and water bottlers. 

Portola Packaging is based in Naperville, IL, and Integra-Seal calls Kingsport, TN home. Portola has an existing 90,000 square foot Kingsport facility where it molds tamper-evident closures and employs 110 people.

Twelve-year old Integra-Seal injection molds low-density polyethylene (LDPE) tamper-evident closures, with its "claim to fame" its 38mm Integra-Lock snap-on tamper-evident closure. According to Integra-Seal, the tooling it designed to mold these closures creates a redesigned flange that improves tamper-evidence and gives a closure a smoother appearance. It also recently commercialized a similar closure but with snap-screw function.

Integra-Seal's president Martin McLean will work at Portola in a sales/marketing function while its vice president, Dino Caserta, will be part of the processor's tooling engineering team. Portola's

From the sound of the press release announcing the deal, Portola wanted the molds and the customer list. PlasticsToday has questions in to Portola on whether the acquisition will mean the closure of the Integra-Seal facility, whether other employees will be taken on and whether equipment or plant is includes in the acquisition.

Just a few years ago, Portola ran into tough financial straits, but in late 2008 it exited Chapter 11 bankruptcy to create what its leadership then called "one of the most financially sound suppliers in the market." More recently the company developed a new type of compression molded plastic closure for aseptic beverage packages. Roy Robinson, VP of business development at Portola, told PlasticsToday that the linerless plug closures will be marketed as a replacement for traditional closures in these applications, which have thermoplastic elastomer (TPE) or foil liners to achieve seal integrity for these beverages. By eliminating the liners, the plug design helps minimize package cost and contribute to material source reduction.
