    Hi, I’m Nick. With over 10 years of experience in the packaging industry, I bridge the gap between global retail brands and factory-direct manufacturing. At TIIO, we support logistics companies and retailers by delivering heavy-duty moving bags and thermal solutions without the headache of complex supply chains.

    We handle everything from raw material sourcing to DDP logistics, so you can focus on scaling your business. No more dealing with quality fade or delayed shipments—we make the procurement process seamless and reliable.

    My passion for this industry is deeply personal. I vividly remember a late night on the factory floor, supervising the loading of eco-friendly shopping bags for a client. As I watched the containers fill up, I thought of my little girl waiting at home. She is my inspiration to push for sustainable, greener products. Every order we fulfill isn’t just business; it’s a step towards a cleaner future for her generation.

    I’m always excited to collaborate with partners who value quality and sustainability. Let’s connect and grow together!
