Product captivity & security

It is well known (and old news) now that Wal-mart, Target, Amazon, and Sears, among others, have all jumped on the sustainable bandwagon and have taken a public stance in regards to the use of PVC, most commonly in a clamshell design, for the packaging of retail products.

But with the 'negative' perception to clamshells comes the one main point of backlash that there is a the lack of product security when switching to a more sustainable package.

Well this has been debunked, as it has been noted by many of the major retailers that regardless, whether the product is in a traditional clamshell, a tear-resistant replacement (Natralock), or a sustainable micro-flute clamshell replacement (ClubPak)... the security is equal because the method of stealing the item remains the same.

* With a box cutter, slice the lip of the blister, pull the product out, and then stash the remaining package somewhere else in the store.

Below is a photo from a recent trip to Costco. This item was found on the complete opposite end of the store, stuffed into a toolbox that was on display. Clamshell, tear resistant... it wouldn't matter, this would still happen.

So with that in mind, the retailers have made the choice to be more 'environmentally friendly' knowing that they will continue to deal with the same thief issues.

In this same vein, sustainable micro-flute clamshell replacement packages are typically marketed as more 'user friendly' and easier to open... so for some humor, I threw a few key words into youtube, and the search yielded an incredible amount of 'clamshell rage' videos.

Below is just one of hundreds, and this is definitely one of the more 'civil' ones, as many had clamshells getting backed over by cars and shredded open by a gas powered chainsaw.

Yes, without a doubt or argument, there are products out in the retail environment that require a clamshell package. But for a majority of products on the shelves of the mass retailers, that is not the case.

In the end, the key is to know both sides of the story when talking security and sustainability, it is an advantageous position to be in when dealing with the mass retailers that are controlling the climate of retail packaging.

Clamshells Made With Ingeo Prove Sustainable

PackExpo.com / Business Wire (Press Release) - A first-of-its-kind lifecycle analysis finds that clamshell packaging made from Ingeo, a unique biopolymer derived from plants rather than oil, emits fewer greenhouse gases and uses less energy when compared to clamshells manufactured with petroleum-based rPET (recycled polyethylene terephthalate).

The Institute for Energy and Environmental Research (IFEU), Heidelberg, Germany, conducted the head-to-head lifecycle comparison on more than 40 different combinations of clamshell packaging made from Ingeo natural plastic, PET, and rPET. Both Ingeo and rPET clamshells outperformed PET packaging in terms of lower overall greenhouse gas emissions and lower overall energy consumed. Ingeo clamshells clearly offered further advantages over the petroleum-based rPET in numerous comparisons.

"Brand owners and converters will lower the carbon and energy footprint of clamshell packaging by moving away from PET and rPET to Ingeo polymer," said Marc Verbruggen, president and CEO of NatureWorks, the manufacturer of Ingeo. "This is true with today's virgin Ingeo and, in the longer term, recycled Ingeo will decrease that footprint even more. Furthermore, the high performance of Ingeo biopolymer in clamshell applications means that less material may be required to manufacture them " on average 25 percent less."

Representative results of the lifecycle analysis:

The study showed that clamshell packaging consisting of 100 percent rPET emitted 58.6 kilograms of CO2 equivalents per 1,000 clamshells. Ingeo 2005, a representative grade biopolymer in the study, emitted 49.2 kilograms " an overall 16 percent reduction in CO2 equivalents. The Ingeo clamshell was lighter, yet functionally equivalent in terms of top-load strength.

Energy consumed over the lifecycle for 100 percent rPET clamshells was 1.1 gigajoules. This compared to .93 gigajoules for the lighter, yet functionally equivalent, Ingeo 2005 packaging " an overall 15 percent reduction in energy consumed.

"The study found that Ingeo compares favorably with rPET even when a producer chooses not to lightweight a clamshell," said Steve Davies, NatureWorks director of Communications and Public Affairs. "The study also showed that the next generation of Ingeo biopolymer, which will be available in 2009, offers further improvements in eco-profile and clearly outperforms 100 percent rPET in head-to-head comparisons."

Clear plastic clamshells, like the ones analyzed in the study, are often used for fresh produce and foodservice packaging " for example, lettuce, tomatoes, sandwiches, or deli salads. Currently this packaging is not recycled in either the U.S. or Europe. In the U.S. clamshell packaging typically goes to landfills after use, while in Europe this packaging may be incinerated for waste-heat recovery. The lifecycle study took both end-of-life scenarios into account.
