Patents with Abstracts




“Multilayer plastic containers and preforms typically include one or more layers of plastic resin such as polyethylene terephthalate (PET) alternating with one or more layers of barrier resin such as nylon or ethylene vinyl alcohol (EVOH) to resist transmission of gas, water vapor and/or flavorants, including odorants and essential oils, through the container wall. An important property of containers of this type is interlaminar adhesion to resist delamination between or among the various layers during filling and handling of the containers by the container manufacturer and the product packager, and during use of the container by the consumer. Various techniques have been proposed for increasing interlaminar adhesion, which generally result in a decrease in barrier properties, an increase in manufacturing cost and/or an increase in other undesirable container properties such as haze in the container wall.” [Bourgeoi, US Patent 8,192,811 (6/5/2012)]
