Abstract

The invention discloses a high-oxygen-barrier pearlescent illusion effect composition and its preparation and application. Based on the total mass of raw materials as 100%, the composition comprises: 90%-99% of barrier polymer, 0.1%-3% of metal oxide-coated silicon dioxide flakes, and 0.1%-5% of silicone resin microspheres %; Silicone resin microspheres include one or more of 105, 120, 130, 145. The preparation method of the composition comprises: mixing the raw materials according to the ratio, adding them into a twin-screw extruder for extrusion, and obtaining the pearlescent magic effect composition with high oxygen barrier property. The composition is suitable for preparing a film with a pearlescent illusion effect with high oxygen barrier property, and is especially suitable for packaging products such as ingredients and raw materials sensitive to oxygen.

Description

technical field [0001] The invention relates to the field of pearlescent illusion effect films, in particular to a pearlescent illusion effect composition with high oxygen barrier property and its preparation and application. Background technique [0002] The thermoplastic resin polyethylene terephthalate (PET) has been widely used in the preparation of various types of packaging materials. However, due to the permeability of PET to oxygen, the shelf life of oxygen sensitive products will be shortened. Food and drug packaging materials often need to have high oxygen barrier properties to prevent the packaging materials from deteriorating or corroding in contact with oxygen. [0003] In order to improve the barrier properties of packaging materials, the packaging industry uses ethylene vinyl alcohol copolymer (EVOH), cyclic olefin copolymer (COC), nylon 6, amorphous nylon, etc. for inert oxygen barrier layer material layer and other polymer layer composite into a multi-laye...
