While McDonough will not reveal the exact PE grades used for this application, he notes that printed shrink film requires low haze, cutability, shrinkability, and sealability. As a result, the layers are all composed of various PE blends, including HDPE and LDPE, L/LLDPE and mLDPE, which is standard industrywide for printed shrink film used for water-bottle packaging. Berry runs three-layer coextruded blown collation shrink film made of various PE blends to achieve low haze, cuttability, shrinkability, and sealability.

He says, "The ability to print on collation shrink film is essential for applications where branding is so important. More and more companies see its potential, given the opportunity to achieve cost and sustainability goals while still capturing consumer attention with strong branding and shelf appeal." According to Dow's Kalia, Oskar Blues' printed shrink-wrapped mixed case is indeed a first for the U.S. craft-beer industry. "Other arrangements, including four-packs in similar packaging, are becoming common in North America, and printed shrink-wrapped cases are already common in other regions, including Europe and Latin America." Kalia notes that now that printed shrink packaging is possible, the Dow team believes that more brand owners will move their products to this type of packaging to take advantage of the cost, manufacturing and sustainability benefits. Printed collation shrink film offers a cost-effective, sustainable secondary pack- aging option to the rapidly growing craft-beer industry. 12 AUGUST 2018 Plastics Technology PTonline.com F I L M P A C K A G I N G Close -Up On Technolog y
