Polymer films and other molded packages require more and more protective layers. This coating extends the shelf life of packaged foods by preventing gases such as oxygen and carbon dioxide, maintains the taste and aroma of the food, and is moisture-proof.
Polymer Research and Development at Micro Coatings Technology (MCT) has made gratifying results on the transparent protective layer of SiO2 for the packaging industry. In the first few months, the polymer department focused on polyethylene terephthalate (PET). ) Film and bottle on protective layer. Permatech's analysis shows that these PET-resistant coatings have an oxygen delivery rate (OTR) of 3.6cc/m 2 -day at 38°C and 75% relative humidity (RH). The coating thickness is 50-150 nm.
In the open air, MCT successfully applied coatings to temperature-sensitive polymer substrates such as low-density polyethylene, polypropylene, polycarbonate, PET, and nylon, using combustion chemical vapor coating (CCVD) technology for heating. The temperature of the flame can be adjusted by controlling the paint gas sprayed directly onto the polymer surface. On the polymer coating, no substrate deformation was found.
The coated packaging material is biodegradable. After packaging materials such as PET are coated, the variable cost can be reduced, the waste can be reduced, and the reservoir layer can be controlled more flexibly.
