They are made from PET polymer, a linear thermoplastic polyester resin, and are clear, flexible, transparent, or translucent. PET film is a high-performance plastic film that typically costs more than other plastic films and has a number of special qualities that are necessary for a variety of end purposes.
High tensile strength, durability, heat resistance, superior gas-barrier capabilities, dimensional stability, chemical inertness, and clarity are just a few of the advantageous properties that PET film naturally possesses.
Depending on the requirements of end users, PET film is commercially available in a variety of widths, thicknesses, and characteristics. It can be produced in a single layer or as a multilayer film by coextruding it with other copolymers to incorporate the desired properties of each ingredient.
During the polymerization of the PET resin, by adding chemicals like slip modifiers (surface modifiers) or colour additives, or later during the production process of PET films, where different surface finishes may also be imparted by externally treating the films’ surface, the product can acquire the distinctive physical properties of the various types of PET film (s).
The PET film’s biaxial orientation increases its crystallinity, which enhances its tensile strength, heat resistance, and gas-barrier qualities, making it appropriate for uses including food packaging, electrical insulation, and printing sheets.
One of the primary reasons for the increasing popularity of BoPET films is that they meet environmental standards. Consumers today recognise the importance of environmental preservation. As a result, they actively seek out sustainability features in the products they purchase. Here, as opposed to regular plastic, BoPET films prove to be the ideal solution.
The films are completely recyclable and can be easily reprocessed into a variety of other products for a variety of applications. When it comes to protecting your products from air pollution and toxic chemicals, these films are your best bet out of all the options on the market.
Despite the numerous advantages that Biaxially-oriented Polyethylene Terephthalate films provide, they are less expensive than comparable alternatives. These films, as one of the most effective solutions, significantly reduce costs. BoPET films, unlike other plastics, do not require delamination and are naturally resistant to ultraviolet rays.
They are well-known for protecting products from external damage and harsh weather conditions during transportation and storage. This assists businesses in lowering the costs associated with replacing damaged goods. Because they are sustainable, these films comply with the majority of global sustainability regulations. This makes the shipping process easier for businesses and manufacturers.
The Global BOPET High Transparent Film market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
A metalized biaxially oriented polyester (BOPET) film with a superior gas barrier that provides high moisture and oxygen barrier for almost all applications, including the substitution of aluminium foil, is called FLEXNET PROTECT TM F-HBP-M.
High optical density and high barrier are specifically suited for the majority of flex pack product offers thanks to the unique BOPET Film technology.
Utilising our sophisticated web metalized surface inspection technique, this film has been fully web examined.F-HBP-M film has excellent, measurable advantages due to its extremely high optical density.
It has a highly changed surface on one side and has been metalized on the other side using a corona process to provide exceptional gloss, high tensile strength, and cutting-edge gas barrier qualities.
This film is appropriate for applications requiring a prolonged shelf life, including the replacement of aluminium foil in numerous flex pack arrangements.
Due to enhanced film handling and machinability when compared to legacy technologies, converters are able to produce less scrap and see fewer down-stream customer rejections.
The distinction between BOPET and other biaxially oriented films lies in how little material is treated to produce maximal packaging effect and unbeatable barrier qualities. By using less energy, the coextrusion and biaxial orientation further streamline the procedure.
However, producers of BOPET film stretching lines are constantly seeking ways to make films even thinner while keeping their distinctive qualities. Reduced material input will therefore result in higher output, more efficiency, decreased cost, increased flexibility and reliability, less waste, and a smaller carbon footprint.
Although sequential film processing has continued to be the industry standard for the biaxial orientation of BOPET films, it has a limited size and yield range and calls for two separate procedures.
Simultaneous Film Stretching Lines have a role in this. Simultaneous Film Stretching, uses the LISIM (Linear Motor Simultaneous Stretching) technology, which use linear motors to simultaneously stretch the film longitudinally and transversely. This technique has an extremely high production speed with a maximum of 500 m/min. BOPET films produced with LISIM-Sequential Film Processing as a result have higher quality and uptime.
