One of the most important factors that companies in the manufacturing sector pay attention to is packaging. Flexible packaging for food and other consumer goods has existed for a long time and is now essential for efficient distribution, food protection, and economic benefits. Modern packaging cannot exist in its countless […]

The global adhesives and sealants market is estimated to reach $237.07 billion by 2030 and is expected to grow at a CAGR of 10.1% from 2024 to 2030. Construction and building sector driving market growth The positive outlook for infrastructure projects across Asia, the United States, the Middle East, and […]

The achievement of multilayer structures has enabled us to enhance the application of plastic materials for food packaging. Sometimes, there is no single material that meets all the requirements necessary to preserve a product. Therefore, combining different materials with varying properties and functionalities makes it possible to provide an optimal […]

Polyurethane laminate adhesive is applied as a single layer on various types of packaging, including cardboard and plastic, which enhances the strength of the packaging. Laminate adhesives are typically used in the production of flexible packaging. They are effective in creating a strong bond between two surfaces, allowing for the […]

The doctor blade, also known as a metering blade, is a tool used in various industries, particularly in printing and coating applications. It is a thin, flat strip made from metal, plastic, or composite materials that is used to remove excess ink, coating, or other liquids from a surface. Taknam […]

Basic principles of corona treatment Corona treatment is a type of electric shock treatment that enhances the adhesion of the substrate surface. The purpose of corona treatment is to alter the surface energy of various substrates and facilitate their bonding with printing inks, coating materials, and laminating adhesives. Taknam Keyhan […]

  The classification of methods and essential tests for the raw materials in the printing industry within a specific group allows us to gain a clear understanding of matters related to printing and the lamination process in flexible packaging without confusion. To realize the knowledge-driven motto of Teknam Keyhan Polymer, […]

Classifying printing methods into a few specific groups allows us to gain a clear understanding of the concept of printing and the structure of all printing devices without getting lost in the various types of machines and their differences in dimensions, applications, auxiliary equipment, and levels of automation.

What is thermoplastic polyurethane? Thermoplastic polyurethane, or TPU for short, is a linear block copolymer made up of hard and soft segments. Soft segment (polyether or polyester): This segment is made from polyols and isocyanates, providing flexibility and the elastomeric properties of TPU. Hard segment (aromatic or aliphatic): This segment […]

The first flexible film Is cellophane, a thin and transparent sheet made from regenerated cellulose. Its low permeability to air, oils, greases, bacteria, and liquid water makes it useful for food packaging. However, cellophane is highly permeable to water vapor, which can be mitigated by coating it with nitrocellulose lacquer. […]
