KHS develops wide-neck PET containers


KHS has developed wide-neck PET containers which are suitable for the hot filling of food. With its low weight and good recycling properties this line-compatible container reduces the carbon footprint throughout its entire life cycle. This alternative to the non-returnable glass receptacle also provides a high level of product safety thanks to FreshSafe PET® coating, claims KHS. 
The new, hot-fillable, wide-neck PET containers for food from the systems supplier – an unbreakable, resource-saving and highly customizable alternative to the traditional non-returnable glass container. This line-compatible type of packaging can be produced on the energy-efficient InnoPET Blomax Series V stretch blow molder in what is known as the blow-trim process or from preforms with a molded neck which can be crystalline as required. The PET alternative has been designed to withstand both the positive and negative pressures which can occur in the closed container following the filling process.
KHS has consciously opted for PET plastic for its new wide-neck containers. The plastic packaging is primarily worth considering from an ecological standpoint alone. Even when full the plastic container has a clear ecological advantage over glass en route to the consumer thanks to its low weight. PET containers also have a higher energy efficiency than non-returnable glass receptacles. During both in-house manufacture and recycling they consume considerably less energy and thus ecologically harmful CO2, says KHS.
Numerous benefits are to help beverage bottlers to cut their carbon emissions by up to 90% – especially if they use containers with a high recyclate content. Another advantage of PET containers is their great capacity for individual design. This aspect is particularly important when it comes to hot filling. For products which are extremely sensitive to oxygen the wide-neck container can be given a tried-and-tested FreshSafe PET® coating. Thanks to the thin layer of glass applied to the inside of the bottle, this barrier coating provides optimum product protection. This type of container combines all the advantages of light, fully recyclable plastic packaging withthose of a gas-tight glass container, the company reported.
