Katrina is a housewife, just like some of you, who dedicates herself to family life— raising kids, feeding pets, cooking healthy and organic food. She has a chemistry background that has given her a solid foundation to start Green ‘N Pack.
One day, when Katrina was having afternoon tea with her circle of girlfriends, they talked a lot about the recent plastic ban and the many good points of using reusable green bags—the ‘bag-for-life’ bag. At the time, someone (we believe it was Katrina herself) came up with a question: "But we are not going to reuse our trash bags, pet waste bags and baby diaper sacks, so what are we going to do with them then....?"
Suddenly, there was a silent moment that the person who started the conversation to show off her beautiful bag-for-life didn't know how to respond to. Then it was Katrina who continued the conversation by asking another question: "So, which of you can promise no longer to use plastic bags at all?" The answer was, obviously, no one. Then everyone realized that, though the bag-for-life is good, we will never give up using plastic bags. While the plastic ban is the stimulus for people to save resources and reduce waste, we will never give up plastic and so we need to find a solution for plastic and for people who work in the plastic industry.
Katrina, as a working housewife, started to research advanced technologies in the industry and she found that there are many types of advanced technologies on the market that proclaim themselves the solution to "plastic forever" (Wiki) by applying biodegradable plastic technology to make plastic bags biodegradable, degradable or compostable. With different degrees, types, conditions and percentages of biodegradation, there are many plastic products appropriate for different purposes. For example, look at how we manage food waste in the compost pail: we should use a compostable bag if we are going to dispose of that food waste in the local compost program. If the food waste will not go to the local compost program (or commercial composting facility), then we cannot use the compostable bag for home compost because it will not biodegrade over time. See? Tricky!
Another example: bags that are made from biodegradable material are not strong enough to handle heavy duty work and often they are made much thicker to achieve the same performance as normal plastic.
Finally, Katrina came up with a solution: let's make these bags which we're using now ‘controlled-life’!
So, this is all about how Green ‘N Pack controlled-life bags started to be made. These controlled-life bags have a pre-determined safe service life—the same idea as we see on most food products, labeled with a best before date. The formula to make these controlled-life bags is carefully developed and field experimented in different parts of the world (mainly in the USA, the UK, Japan and China). Some customers asked me why we needed to do experiments in different countries. The answer is simple and straightforward: think about how the same cow producing the same milk would keep for longer in winter in Tokyo than in summer in California.
The controlled-life formula is achieved by simply combining 20% pre-consumer plastic with 80% controlled-life polymer made from 1–3% manganese-based oxo-biodegradable additive and 97–99% #2 or #4 BPA-free plastic. With different concentrations of the controlled-life essence, these bags will perform differently and thus conclude their safe service life differently according to time scale, user application and conditions. These bags are not only made to be controlled-life, but are also designed to keep up with eco-conscious and healthy lifestyles and user experiences. Our core value is to make life better, and doing something is better than doing nothing.
