Polypropylene is an ideal material for reusable packaging of all kinds because of its durability and flexibility. This is one of the plastics that can be put in the freezer, then the microwave or dishwasher without fear of it loosing its shape or leaching toxins (the food-grade polypropylene used in CuBE containers is virgin, meaning no toxic additives are needed).
These are some great polypropylene food containers on the market:
1. The Keepcup is an alternative to the sustainability issue of non-biodegradeable take-away coffee cups as Keepcup has an estimated lifespan of four years! It's made from reusable and recyclable polypropylene and is "unbreakable”, light weight, stackable and thermo insulating.
2. The CamelBak Better Bottle represents a new standard of performance and convenience in re-usable water bottles. Available in multiple colors, this innovative bottle is also BPA- and Phthalate-free. It's easy to carry and attaches to most water filters and fits in most cup holders. Also, it's dishwasher safe.
3. Inspired by Japanese Bento boxes,The Laptop Lunch Box is a new and creative way to make a daily packed lunch. Made entirely from non-toxic food-grade polypropylene and polyethylene, the Laptop Lunch Box System includes five reusable containers and a knife and fork. The reusable boxes remove the the need for plastic sandwich bags reducing how much you need to throw away, while also making it easier to pack fresh fruit, vegetables and home cooked meals.
