Overview

This FDA approved film does not stretch due to the orientation of the layers during the lamination process. Great for Food and industrial uses, The kraft paper can be either White or Brown kraft and is combined with a heat sealable PE liner. This is a low barrier product which is best suited for shelf stable products that do not require high barrier packaging to extend its shelf life.

Note: The performance of any film will be influenced by a number of factors and testing must always be performed to ensure the film meets the use.

CareKraft-KVP

This material has high barrier to moisture vapor and oxygen but low physical strength and the unprocessed paper exterior can crack and crinkle, and tear easily, and must be handled and stored with more care than a plastic product. The natural paper exterior is subject to natural variations in color, texture, and all visual elements between each lot.

The brown natural Kraft exterior makes the structure rigid, but it tears easily in both directions. The foil provides excellent barrier to extend shelf life and protect the taste profile. The polyethylene sealant layer is extruded brown to mask the color of the foil. This unique design element makes the PF500 BRN a good fit for customers that do not want to see foil in their packaging but need the protection that it exhibits.
