December 03, 2018, Elizabethtown, Kentucky (USA): Flex Films, the global film manufacturing arm of Uflex, has been granted United States Patent covering entire categories of Formable Films that include one or more BOPET layers used in Alu Alu blister packaging.

The patent US 10131122 was issued to Flex Films (USA) Inc on November 20, 2018 for a period of 20 years, lending a competitive advantage to the Films Business of the company over its opponents in cold formed pharmaceutical packaging industry.

This patent has a uniqueness of forming characteristic of BOPET film in Z direction during packaging application.

With this innovation in pharma packaging and particularly for Alu-Alu blister laminate structure, BOPET film has completely replaced the carcinogenic PVC. When PVC is recycled or reprocessed, it releases poisonous gases like Dioxin & Hydrochloric acid which are hazardous for human health. Also when PVC comes in direct contact with sunlight, it gives away Chlorine gas. Whereas the special polyester film can be recycled and reprocessed and is 100% environment friendly. Likewise, this BOPET film has also replaced 25 microns BOPA film, the processing of which is difficult due to its intrinsic property of moisture absorption that makes it de-laminate from aluminum foil.

Rotogravure or Flexography Printing?

Image
  Picking sides in this case won’t be easy and straightforward!!! Both Flexographic and Rotogravure printing technologies are well established in their own stature and have their fair shares of advantages and disadvantages. Let’s try and understand the principle of Rotogravure and Flexographic Printing Technology! Gravure printing is a type of intaglio printing process; i.e., it involves engraving the image onto an image carrier. In rotogravure printing the image is acid-etched on the surface of a metal cylinder—one cylinder for each color—in a pattern of cells. The cells are recessed into the cylinder, unlike relief printing or letterpress where the printing image is raised, or like offset printing, in which the image is level with the plate. The cylinder is etched with cells of different depths. These cells hold the ink that is transferred to the substrate. The dimensions of the cells must be precise because the deeper cells produce more intensive color than shallow cells. Read M...
