Can now post-consumer recycled plastics be used for food packaging?
Hi, I have been curious if now the post-consumer recycled plastics can be used for food packaging? What will be the criteria in identifying its food safety. We cannot know how the plastic trash mixes with all other chemicals and ...???!!! Recently, hearing news of using r-PET for water bottle in markets. Will there be any strict guideline for that? Many Thanks, Kitt
Posted August 27, 2010Is Pre-printing Carbon Footprints on Consumer Package a Sustainable Approach?
With the more environmental concerns today, there are coming more preprinting carbon footprint on the consumer package to show consumers how much CO2 is emitted.
Posted February 3, 2010What's the difference between biodegradable vs. compostable?
Please help to explain the difference between biodegradable vs. compostable materials. I have read through several definitions but am still not quite clear on it. Both seem to end up with CO2, H2O and biomass, while biodegradable will be degraded by microorganisms. But some compostable material might be involved with microorganisms as well. Is this right? Please share some examples of materials in these groups. Many thanks!
Posted July 26, 2009Food Grade vs. Non Food Grade Printing Inks
Could you please advise what specific criteria is used to differentiate between food grade and non-food grade printing inks? For example, heavy metal levels or any solvent limits? Is the criteria used a worldwide or global standard? Also, for those toluene-based printing inks, is there any regulated residual solvent limit for food packaging? Many thanks.

As from the consumer trends around the world is going towards more retail pack sizes due to the smaller family and fast going of the population, yet this consumer requirements trend would be opposite to the environmental and packaging waste concerns. Also, when dealing with retail pack sizes, the more packaging levels can be involved leading to higher packaging waste per net weight of product.
Posted March 16, 2009How to conduct migration test on paper with film laminated packaging?
Dear Experts, As far as I know from the regulation, the migration test is mainly for plastic type packaging. Then, how can we conduct such test on paper / paperboard packaging with or without film laminated. Can the test condition may dissolve the fiber as well. Hence, how can we ensure the food safety issue on the paper packaging. This may include ink components migration. Especially, there has been 2 cases of photo-initiators migrated from paperboard packaging. Many Thanks, Kitt
Posted March 9, 2009Are biodegradable plastics really the positive solution for the environment?
Dear All Experts, Could you please share your points if the bioplastic is really the positive solution for food packaging? While the concept of carbon footprint seems that the biodegradable plastics could be the future issue on CO2 + CH4 emission. Even the paper packaging could fall into the similar concerns. So what type of materials are really positive solution for environment --- e.g., paperboard, recycleable plastics, or bioplastics. Thank you very much, Kitt

Hi I was also curious on this
Hi I was also curious on this point too with the following post. Please share.... Thank you, http://www.greenerpackage.com/discuss/green_marketing/pre-printing_carbon_footprints_consumer_package_sustainable_approach
Paper Tray for Frozen Meals
I am quite curious that many say paper is more energy and water consumption to produce. But the same time there are more paper tray coming out in the market and is believed as greener than plastic. Then what will be the fact and the right answer for social and environment? One point I would like to add that the common spec of paper container would be laminated with PE film. Then at this spec level, is it really considered as safe to put such tray in microwave oven? Because the foods heated by microwave could easily rise the temperature around 100C or even higher. While, it is known that PE would melt around 100C but may start to deform below its melting point. Also, the paper is basically porous and almost no barrier to the printing inks and solvent from the outer layer of the package. At the same time PE is non polar and would let the fat/oil to penetrate into. Or are there any other proper paper tray specs for the frozen meals?

Any indicators to exhibit packaging design sources optimization?

Also, when dealing with retail pack sizes, the more packaging levels can be involved leading to higher packaging waste per net weight of product. Learning from Waste and Resourses Action Program (WRAP) in the EU that they have gathered the Best-In-Class (BIC) of packaging systems related to various product types. The information of the packaging weight used per net weight of product available in the markets are grouped. However, it could not be found the detail packaging system to be compared. How can we, as the packaging designers, optimize or balance out the said 2 opposite directions during the packaging development of a new product launch? Would there be any indicators to tell us if such packaging system is considered to be readily optimized upon its first launch?
