Buyer acknowledges that information in Seller’s marketing materials, technical data sheets and other descriptive publications distributed or published on its websites may vary from time to time without notice. Buyer acknowledges that Seller has furnished to Buyer Safety Data Sheets, which include warnings together with safety and health information concerning the Product and/or the containers for such Product. Handling of Personal Data.

In order to meet demand and avoid delays, multiple PCR sourcing outlets are often necessary and multi-pass recycling is utilized, both of which can increase the risk of polymer degradation impacting mechanical properties and creating potential product safety issues due to food contact concerns. Convertors and brand owners need to make educated choices for their recycled materials based on formulation expertise and data science to help achieve a consistent packaging product. Based on color science, the tool helps optimize the ratio of virgin resin to PCR in order to achieve the best acceptable rendering, proven by scientific data.

SAFETY & HEALTH INDEMNITY Buyer acknowledges that Seller has furnished to Buyer Material Safety Data Sheets as required under applicable laws and regulations, which include warnings together with safety and health information concerning the Product and/or the containers for such Product.
