- Global EVOH Resins Market: Percentage Breakdown of Volume Sales by Leading Players for the Year 2019
[USPRwire, Thu Jul 25 2019] "EVOH Films for Packaging Market Forecast, Trend Analysis & Competition Tracking - Global Review 2018 to 2028" features the most accurate and precise presentation of unique industrial facts about EVOH films for packaging market.
Based on the product type, EVOH films for packaging market is segmented as blown films and cast films.
The new pouch uses an EVOH barrier, combined with Dow's Retain resin technology to allow the multilayer film to be fully recyclable.
* Ability to run up to three nylon layers with the EVOH main barrier layer.
Oxygen transmission rates (OTRs) increased by 5 and 2.2 times, and the water vapor transmission rates (WVTRs) increased by 30% and 10% after the PET barrier layer and the EVOH barrier layer, respectively, were processed.
During film processing, the EVOH layer is positioned as the middle layer, and PP, which has excellent high water barrier properties, is made of the outer layer in a typical three-layer film.
Kuraray was the first to commercialize the high-performance EVOH resin, which it launched in 1972 under the brand name EVAL.
The process is based on the coinjection used by Kortec to mould PET bottle preforms and injects the EVOH barrier layer into the cap in a single cycle, with no time penalty over mono-layer injection.
For greater barrier properties, the tubes can be lined with ethylene vinyl alcohol copolymer (EVOH) that helps ban air contamination from the product.
