FLEXIBLE PACKAGING PRODUCT DATA SHEET

Product Description

OPPalyte WOS-2 is a one-side treated, one-side sealable, white opaque OPP film with a proprietary cavitated core. WOS-2 was developed to provide performance improvements over 278 WOS in terms of lower and more consistent COF, lower MST, and improved print performance. WOS-2 was developed and designed for frozen novelty applications. The stiffness, slip characteristics, and sealability of WOS-2 have been optimized to provide outstanding performance on multi-lane equipment.

Key Features

  • Outstanding opacity
  • Robust machinability
  • Heat seal range of approximately 115°F (63°C)
  • Average seal strengths over 480 g/in (480 g/2.5 cm)
  • Bright white appearance
