Increase shelf life and prevent food waste

Packaging is THE leading solution to increase shelf life and prevent food waste.

We blend of food and packaging science and value chain expertise to increase the shelf life of foods for Brands, Packaging Suppliers and Converters, and Retailers. 

PTR links the value chain to balance costs for packaging that increases food shelf life and prevents food waste because shelf life extension allows for expanded distribution, Retailer display-time, and Consumer use.

This ensures that the business case is well-defined and Brands, Retailers, governments (EPA, FDA, USDA, just in the USA), UNSDGs support the initiative.

PTR has vast experience helping businesses increase shelf life. We have extended the shelf life of 100+  bakery, snacks, dairy products, meats, produce, pet food, and frozen foods. 

​Specific Capabilities, Case Studies of prior work, and Toolkit follow.
