About SvartxLab

Professional Packaging for Food Delivery

SvartxLab is an agile B2B packaging distributor based in Madrid, supplying certified thermal delivery bags (ProThermo) and lidless paper cups (Calix) backed by third-party audited manufacturing facilities. We serve restaurants, ghost kitchens, cafés, and foodservice distributors across Europe and international markets.

Our Mission

We believe food delivery deserves better packaging. Our ProThermo™ bags were tested by an accredited laboratory for food-contact safety and are designed to keep food warm for 45 minutes in transit. Our Calix cups replace the plastic lid with a built-in fold. Your reputation depends on every delivery arriving right, so we publish the test results.

What We Stand For

Safety First

ProThermo™ is tested to GB 4806.13-2023 at a CNAS/ILAC-MRA accredited laboratory, and the paper cups used for Calix are tested by Guangdong SCS under LFGB. We publish report numbers, laboratories and results.

B2B Focused

We operate as an agile B2B distributor and importer, connecting restaurants and foodservice operators directly with accredited, audited manufacturing partners. Our supply chain, MOQs, warehousing, and delivery workflows are structured for professional foodservice scale.

Sustainability

Calix cups replace the plastic lid with a built-in fold, and Calix Eco, a water-based barrier version, is in development. Fewer plastic lids to buy means less plastic waste and less exposure to Spain's Ley 7/2022 plastic tax.
