Text version of the page

Uni-FoamTM PS-113 Product Description PS-113 innerseal is a thin gauge uniform polystyrene foam coated on one side with a specially formulated torque-activated adhesive. This product exhibits a minimum of surface tack which minimizes roll blocking and facilitates punching and insertion of the innerseal disc. When used with either metal or plastic caps, and properly torqued, PS-113 provides excellent adhesion to glass and plastic containers. PS-113 is simple to use, and although not designed to provide barrier properties, provides a degree of moisture vapor barrier if properly sealed to the bottle. See Typical Physical Properties below. Typical Applications PS-113 innerseal has been designed primarily for packaging dry food and over-the-counter drug products not requiring the innerseal to be the primary form of tamper evidence. Examples of products using PS-113 innerseal include vitamins, powdered laxatives and antacid tablets.

NOTE: FDA Compliance Policy Guide; No 7132a.17; Chapter 32a, concerning Tamper-Resistant Packaging Requirements for Certain Over-the-Counter (OTC) Human Drug Products, has been revised to state that Polystyrene foam container mouth seals applied with pressure sensitive adhesive are no longer considered effective tamper-resistant features. Storage & Handling: Pressure sensitive innerseals in roll form, and prior to inserting into a closure, are heat sensitive. Storage at elevated temperatures can result in difficulty of handling during the lining process. It is suggested that PS113 innerseal be stored in a cool (Less than 60°F or 15°C)or refrigerated PS-113 file:///C|/JAMES/Unipac 2004/html/ps-113.html (1 of 2) [1/2/2004 12:03:28 PM]
