High barrier BOPP film is relative definition since the concept is strictly dependent on applications: Flexible packaging materials are the subject of this paper and shelf life requirement for the different products set the barrier properties level. High barrier BOPP films are flexible and used in a varied kind of applications such as plain films, heat sealable films, multi-layer films, metallized films, pearlized films, synthetic paper, white opaque films, label films, shrink films, high barrier films, and capacitor films.
Metallized high barrier BOPP films have wide application by the food industry to prevent leakage.
Among all these application of BOPP films, high barrier BOPP films are designed for fresh food items and are produced in connection with other materials such as PA or EVOH in or nine seven-layer configurations. Block bottom Food packaging is one of the primary markets for a new high barrier BOPP film. This packaging film promises high oxygen, high clarity, and moisture barriers and, notably, lacks polyvinylidene chloride (PVdC).
This type of high barrier BOPP films is designed for use as the inside sealant web for the packaging of crisp salty snacks, bakery items, crackers, cookies, granola, confections, fruit and nut mixes, and as well as non-food items and dry pet food and treats.
