Melamine, a synthetic triazine compound and an organic base is known to impart scratch, wear and puncture resistance to packaging films, thereby enhancing the strength of the ensuing laminate structure, but the cons of the compound over weigh its pros. The contamination of pet food with melamine and its analogue cyanuric acid led to kidney failure in thousands of dogs and cats in North America in 2007. A year later in 2008, melamine again made headlines for wrong reasons - this time detected in powdered milk, the compound was associated with kidney disease in babies.
Amid growing demand from western food and beverages brands for melamine-free packaging, Uflex, India’s largest multinational flexible packaging materials and solution company, at its film manufacturing plant in Poland has developed Grade ‘F-AMF’ – melamine-free acrylic coated bi-axially oriented polyethylene terephthalate (BOPET) clear transparent film that is finding extensive use in conversion, printing, hot fill, retort, pasteurisation and sterilization, among other applications.
The trials that were conducted at Flex Films Europa Sp. z.o.o. (Poland) have yielded excellent results in terms of nil melamine content, good printability and enhanced lamination bond. The film exhibits good transparency and clarity along with excellent machinability and handling properties. One side primer coating provides emphatic adhesion with inks and adhesives. The acrylic coated surface is also recommended for surface printing. The other side of film surface can be corona treated for value addition. The film possesses good mechanical, surface & thermal properties and ensuring excellent processability. This film has been specially developed for FFS machines.
The films, FLEXPETTM and FLEXMETPROTECTTM (Grade F-AMF) are manufactured with monomers/starting substances listed in commission regulation (EU) 10/2011 relating to plastic materials and articles intended to come in contact with foodstuffs. All additives used are listed in the plastic regulation (EU) 10/2011. The additives also comply with the BFR (German federal Institute for Risk Assessment, previously known as BgVV & BGA) Recommendation XVII, Polyterephthalic acid diolesters.
Upon successfully developing the melamine-free acrylic coated bi-axially oriented polyethylene terephthalate (BOPET) film, Pramod Sirsamkar, president, technical and new product development (films) at Uflex Limited, said, “Looking into the growing consciousness towards health, this Film has been particularly developed amid increasing demand from our customers globally.”
Ashok Chaturvedi, chairman and managing director, Uflex, expressing joy on this development said, “Melamine-free acrylic coated bi-axially oriented polyethylene Terephthalate (BOPET) film is a testament to Uflex’s unwavering commitment towards consumer safety and customer satisfaction across the globe. Additionally, this film also exhibits excellent transparency, gloss and printability making it an absolute delight for the converters.”
