When people think of eco-friendly packaging, they typically think of the resources and materials used to make up the packaging. They worry about the corrugated material used, where it came from, natural resources that were used to physically make the fiberboard sheeting and what measures are taken to ensure the materials are certified as eco-friendly. But are there any ways to take the ecological aspects of packaging a step further?
Eco-friendly packaging doesn’t stop with the package. Beyond the corrugated material and the natural resources used to manufacture the fiberboard sheeting, there is the ink used to design and brand the packaging before it reaches the consumer.
With recent advancements in more natural alternatives to water-based acrylic inks, Packaging Services Industries has moved towards implementing these sustainable materials into their own daily operations.
Packaging Services Industries chooses to use environmentally friendly inks and varnishes. Eekoflex inks and varnishes (developed by BCM Inks USA, Inc.) have replaced many of the petroleum-based resins with rosins from pine trees. Water-based flexo inks, by their nature, are the most environmentally and ecologically friendly printing inks in use today.
The rosins used in these inks and varnishes are a byproduct of the paper and pulp manufacturing process making. These eco-friendly inks have very low VOC’s (volatile organic compounds) and contain NO heavy (TPCH/CONEG) metals, i.e., Lead, Mercury, Cadmium and Hexavalent Chromium. With every drum of Eekoflex inks and varnishes, it is estimated about 3 gallons of crude oil is saved.
PSI is dedicated to providing packaging that reflects a more sustainable world through smarter solutions and actively improve our process every day, constantly looking for ways to save resources and use more environmentally friendly materials.
