The white pigmentation provides UV protection and is such a small percent of the composition that it does not affect the environmental aspect, according to blow molder Alpha Packaging. The bottles are supplied through distributor TricorBraun.
The PLA is one-third more costly than PET, says Scott, but Highland is absorbing the added costs because "we feel that this is an important thing for the environment. Once consumers are aware of this packaging option, they love it."
Highland is promoting its eco-friendly packaging by adding to the top of the closures a pressure-sensitive label printed with the words "corn based, earth friendly". The company is testing several different brands and variations of labels made of recycled paper, which the company has used for promotional materials and catalogs for years. That change from virgin paper labels should come shortly, says Scott. Highland is also looking into PLA-based closures.
