As part of the package, the closure of the packaging more environmentally friendly appeal. "Obviously, when reduced in size from 43 mm to 38 mm, or 33 mm, the closure will reduce a lot of weight, but also in the entire vessel." Silgan White Cap Americas commercialized Technical Director Bill Thomas said. For hot-fill PET packaging, this is especially important. If the weight of the closure and plastic packaging similar to its performance is being reduced, the packaging of the product may be affected by temperature. Silgan is currently changing the shape of the cover and increase the side of the thread, so this lightweight product more durable. According to Thomas introduced, the technology is still in its introductory phase, but in 2009 it will be applied to several products packaging. To reduce the use of raw materials, while increasing the amount of the dumping of packaging products, Tetra Pak has improved the closure of two brick-shaped package. The redesigned second-generation formula lid preceded the pouring area expanded by 50%, and after adding a new generation of Formula tipping area than before opening the lid to expand by 25%. According to Riccardo Vellani Manager Tetra Pak company responsible for the bottle and the closure of business presentation, plus the second generation after capping formula can be reduced to 30% of the opening force. Both types of closure 20% target weight reduction. Phoenix company jointly developed with the Dean of the Milk Chug closure, the company last summer launched the third generation of closure products. Its goal is to provide consumers with more environmentally friendly, more efficient, and has a new look and petrochemicals products Milk Chug closure of company-specific geometry. Len Ekkert Phoenix vice president of engineering, said the company, although the appearance of a new generation of feature-capping has not changed, but it saves 20% of the amount of plastic. Milk Chug closure to maintain the original closed system, it has added a new tamper-evident system so that the tamper evident traces at a glance, while improving efficiency.
Style and overall coordination, however, is not just reinforcing the role of the closure and seal packaging. Under the influence of the economic crisis, the competition is more intense than ever, and food and beverage companies must make their products in the market foothold. They must take into account the effect of the product outside of the packaging, use of every part of the packaging to differentiate the product, rather than the package as a big label.
