Visking Masterbatches
The visking masterbatch means the PE/PA6 visking film masterbatch, used in the middle coloring layer of the 5-layer / 7-layer visking.

Description
The visking masterbatch means the PE/PA6 visking film masterbatch, used in the middle coloring layer of the 5-layer / 7-layer visking. Because the middle coloring layer is usually only one micron thick, it demands the high concentration of the pigment of the masterbatch in this layer and the absolutely uniform dispersion of the color. Otherwise the blank white dots are to produce. Meanwhile, the high hiding power of the pigment layer is necessary to prevent the content from the light to increase the shelf life.
There’s a very high demand for the technology and production process determined by the above features of the visking masterbatch. Due to the rich experience accumulated over years, we have already mastered the mature production technology of the visking masterbatch. The clients who adopt our visking masterbatch has already exported their visking products to Europe and the United States.

Advantage Performance
High dispersion: To select the imported high-dispersed pigment. The visking masterbatch, in accordance with more than the proportion of 30%, is added into the one-micron thick PE coloring layer. Thus it will ensure the uniform distribution of the color to prevent from any color spots and the blank white spots.
High temperature resistance: Maintain the stability of the color and the performance of the visking plastic in the processing temperature exceeds 250℃, without the damage, the precipitation and the transference of the color; Environmental Protection: Heavy metal contents to meet the various environmental protection standards, to pass the FDA food grade.
