If the purchase volume is large, does the factory support mixed batches (mixed packaging of different colors/thicknesses)?

Yes, we support mixed batch customization according to the project list for EPC projects or large-scale projects. For example, 12mm dark gray (NRC≥0.90) can be used for the main walls, and 9mm light color (NRC≥0.80) for the ceiling. We can split the materials into different pallets and affix corresponding area labels to the outer boxes (e.g., Area A - Dark Gray - 12mm), greatly facilitating your site-specific management and material requisition. The above 60+20 FAQs constitute a very comprehensive knowledge base. If you are doing this for website SEO (Search Engine Optimization), we suggest creating separate topic pages for these Q&As categorized (e.g., "Acoustic Knowledge," "Installation Guide," "Export Certification"), which will make it easier for customers to find what they need. If you need other specific areas (such as in-depth Q&As specifically for home theater enthusiasts, or details of on-site carpentry construction instructions), please let me know, and I will supplement them for you!
