Food packaging is becoming increasingly less rigid: PACK EXPO Internaonal 2012 illustrated that what was once mostly a bole/jar/box/can market is becoming a pouch/bag/cup field. Like <strong>the</strong> marketplace, <strong>the</strong> technology on display at PACK EXPO focused on lightweight, material-conserving packaging formats and efficient sys-tems to enable marketers to make, fill and pack <strong>the</strong>ir own packages ra<strong>the</strong>r than packing premade rigid containers. Injection-Molded Cup Technologies Enhance Sealability Nypro Packaging introduced several innovave injecon molded cup technologies. Each provides a uniform, thin-walled sealing flange to improve efficacy during lid sealing: Foil encapsulated PP/Foil/PP food cups with a shelf life up to 10 years: The outer PP layer is molded, a preformed foil sheet with a flat boom and pleated sides is inserted into <strong>the</strong> formed boom, and <strong>the</strong> inside PP layer (blue material in <strong>the</strong> picture) is injected, compleng <strong>the</strong> encapsulaon. There is a per-fectly smooth outside surface, and <strong>the</strong>re would be no evidence of <strong>the</strong> foil with a colored outside. Co-injected PP/EVOH/PP food cups. 32 x 32 cavity molds meet ultra high producon requirements (greater than any to date), maintaining a .011-inch uniform wall thickness and molding in a 5-second cycle. Nypro indicated addional advancements are in <strong>the</strong> works to provide all plasc, co-injected containers with even beer barrier properes. Injecon molded PP cups for Philadelphia Cream Cheese with 360 o in-mold label: Fea-tures included 12 x 12 cavity molds (larger than any to date) and a 5-second cycle me on a 16 oz. container. The tops for <strong>the</strong> containers are also in mold labeled to provide graphics. Injecon molded cups with a 360 o in-mold label on <strong>the</strong> sides, overlapping a boom label for full external container coverage: Labels can be produced with an EVOH layer for 4–12 month shelf-life, or a thin foil layer for up to 4-year shelf-life, providing addional barrier properes for <strong>the</strong> container. A dispensing closure where <strong>the</strong> closure and flip top are molded simultaneously in a 32 cavity double cube system with in-mold assembly, eliminang <strong>the</strong> usual secondary as-sembly operaon. The system molds <strong>the</strong> two separate parts in different colors using cu-be molds, and assembles <strong>the</strong>m as part of <strong>the</strong> total molding operaon. Ejecon of <strong>the</strong> final parts happens independently from <strong>the</strong> molding cycle when <strong>the</strong> mold cubes rotate 90°. It runs an 8-second cycle and produces 100mm+ a year per system. The closures are currently being used on <strong>the</strong> P&G Herbal Essence line of products. Benefits include low unit cost through cycle reducon, WIP eliminaon, floor space reducon and capital cost reducon. – RCC More informaon Aaron Dupont, barrier commercializaon engineer, Nypro: 978.368.4585, aaron.dupont@nypro.com. Takigawa Corp. is <strong>the</strong> licensee for h’eat it, <strong>the</strong> self-heang soup pouch from ScaldoPack. Self-Heating Soup Pouch Debuts FOOD & FOOD SAFETY Clockwise from top le: Foil encapsulated PP/Foil/PP food cups; In-mold labeled tops and injecon molded PP cups; dispensing closure. All from Nypro Packaging. The self-heang soup pouch technology, “h’eat it,” from ScaldoPack is a “pouch-within-apouch”: The inner pouch contains a nontoxic quicklime-based heang mechanism acvated by a push buon on <strong>the</strong> pouch front. The outer pouch contains <strong>the</strong> consumable product. Accord-ing to <strong>the</strong> ScaldoPack website, a 220-mL pouch will heat to heated 35°C (about 100°F) in five minutes aer acvaon.

The h’eat it pouch for soup from Abramo, Zwevegem, Belgium, debuted on-shelf in Europe several months ago and sells <strong>the</strong>re for <strong>the</strong> equivalent of $3.99. The company also has a self-chilling form that ulizes <strong>the</strong> same pouch-within-a-pouch structure, relying on salts for cooling. – RTL More informaon Steve Coulson, director, Takigawa Corp.: 416.399.1181; steve@takigawa-corp.com; www.takigawa-corp.com/takigawa-corp/eng/index.html www.scaldopack.be 11 FOOD
