New additive gives PET packaging’s surface friction the slip

Now being offered by Croda Polymer Additives is a new PET slip concentrate said to help reduce surface friction by up to 60%. Marketed under the company's Atmer tradename, Atmer 7510 is a 10% concentrate of IncroMax 100, the company's slip additive for use in polyester-based polymers, in a polyethylene terephthalate (PET) carrier system.

Now being offered by Croda Polymer Additives is a new PET slip concentrate said to help reduce surface friction by up to 60%. Marketed under the company's Atmer tradename, Atmer 7510 is a 10% concentrate of IncroMax 100, the company's slip additive for use in polyester-based polymers, in a polyethylene terephthalate (PET) carrier system.

The active component is claimed to reduce surface friction by up to 60%, making for improved packing and de-nesting of molded parts, reduced scratch and scuff, and significantly reduced mold release force. The new additives can see use in processing of PET film and sheet, and also in injection molding, without any adverse effect on PET color or clarity.

James Lawrence, Croda's sales and marketing manager, notes that because Atmer 7510 is supplied as a free-flowing pellet, it is easy to dose as its physical form and melting point closely match the base polymer. It can be added directly to PET or to the masterbatch in a conventional dosing system.

Target applications include beverage bottles, household and cosmetic bottles, thermoformed trays and tubs, food packaging, and PET film and extruded sheet. [email protected]
