Food safety:KURARISTER™ has passed the specification/standard test of Official Notice No. 370(1959) from Japan's Ministry of Health and Welfare. KURARISTER™ may be used for indirect food contact as outlined by the US FDA's CFR176.170, CFR177.1390, CFR177.1395 and is approved for use as a food package material. KURARISTER™ is approved for use as a plastic material under the EU Directive No.1935/2004/EC. For additional information, please contact us.
What is KURARISTER™?
KURARISTER™ is a transparent high gas barrier retortable film, with Kuraray´s proprietary organic/inorganic hybrid composite coated on both sides of a base substrate.The coating layers are extremely durable and provide reliable high gas barrier properties. KURARISTER™ C is based on PET film and KURARISTER™ N is based on bi-axially oriented PA film, which can be used for a wide range of packaging applications.

Kuraray Co. Ltd. became known as a leader in gas barrier technology with EVAL™ EVOH. EVAL™ resins
and films used in food packaging preserve product flavour and aroma, and prolong product freshness
and shelf life. KURARISTER™ is a new transparent film for lamination, developed to extend these
properties into flexible barrier retort packaging. KURARISTER™ is not an EVAL™ product, but rather
uses Kuraray's proprietary organic/inorganic hybrid technology.

KURARISTER™ protects food contents from oxidation with its reliable high gas barrier performance. The following are the results of storage tests before and after retort, using a methylene blue indicator method*.
*Methylene blue method: Methylene blue gel changes colour with oxidation, allowing to effectively visualise oxygen permeation into a package.

5. Physical Properties
KURARISTER™ provides physical properties equivalent to those of the PET or OPA base film.
KURARISTER™ N impact strength before and after retortThe base OPA substrate is protected from oxidation during the retort process by the high gas barrier of the coating layers. As a result, KURARISTER™ N maintains its mechanical properties after retort even better than a normal untreated OPA film. This combination of reliable mechanical and high-barrier properties makes it suitable for use in cost-saving 2-ply pouch structures.
