Abstract
A low odor packaging film is disclosed. The low odor packaging film comprises an oriented film. The oriented film includes a first odor barrier layer, a second barrier layer and an inner layer that comprises a multicomponent recyclate. The inner layer is present between the first odor barrier layer and the second odor barrier layer. The first and second odor barrier layers reduces the transmission of the odor or the odor causing components present in the multicomponent recyclate of the inner layer with a product or item packed with the low odor packaging film. The oriented film has a low haze value as compared to a non-oriented of the same composition and structure.
Claims16
A packaging film comprising an oriented film, the oriented film comprising:
- a) an inner layer comprising a multicomponent recyclate,
- b) a first odor barrier layer,
- c) a second odor barrier layer, the inner layer positioned between the first odor barrier layer and the second odor barrier layer, and,
- wherein the first odor barrier layer and the second odor barrier layer reduce the transmission of odorous compounds from the inner layer such that the packaging film is suitable for packaging organoleptically sensitive products, and
- the oriented film has a gloss value greater than 60%, as determined in accordance with ASTM D2457-90.
A packaging film comprising an oriented film, the oriented film comprising:
- a) a first odor barrier layer,
- b) an inner layer comprising a polyamide, a polyolefin and a compatibilizer, and
- c) a second odor barrier layer, the inner layer is positioned between the first and second odor barrier layers, and
- wherein the first odor barrier layer and the second odor barrier layer each have an oxygen transmission rate (OTR) of less than 150 cm3 25 micron/m2 day when tested at 23° C. and 50% Relative Humidity (RH) to reduce the transmission of odorous compounds from the inner layer such that the packaging film is suitable for packaging organoleptically sensitive products, and
- the oriented film has a gloss value greater than 60%, as determined in accordance with ASTM D2457-90.
A packaging film comprising an oriented film, the oriented film comprising:
