Plastic Technologies (PTI) has developed a free app that allows packaging producers to calculate the recyclability of their polyethylene terephthalate (PET) bottles, containers and packages.
The PET Packaging Recycling Calculator app lets users see how their decisions regarding materials, barriers, additives, closures and labels can impact the next generation of PET (rPET) produced from their recycled containers.
The free download can be found in the iTunes App Store or Google Play by looking up 'Recycle Calc' and looking for an icon with the PETE resin logo.
From the available options, users can select the PET resin type and indicate if the package is multilayer and whether or not additives, coatings or labels have been used.
The user will also have to indicate if the label releases in a hot caustic wash, whether the inks bleed or transfer onto the PET during the wash, or if the container has a closure, seal or other attachments that float in water.
A summary screen is then available to users where they can modify any of their previous answers and press the submit button once they are finished.
PTI vice president Frank Schloss said: "The only way for brand owners to really be able to claim that their package is fully recyclable and meets APR guidelines is to subject it to testing that can support their position."
The PET Packaging Recycling Calculator is suitable for brand owners, packaging engineers, plastic processors, resin producers and others involved in the PET process.
Designed as a screening tool, the calculator can help users determine whether or not they should consider more in-depth testing.
