FlexFilms (Elizabethtown, KY, USA) has developed a polymer film with a soft surface that is also very durable. The BOPET film called FLEXPET F-STF is said to have special scratch resistance, heat resistance and abrasion resistance. The durable surface can self-repair most of the signs of wear.
"If we scratch off the surface of this film, it will not scratch," says Dr. Steven J. Sargeant, general manager of FlexFilms' technology. The sturdy surface coating combines with a proprietary inlay coating on the base polyester film for a soft touch. This combination gives unique self-healing, toughness and durability as well as a soft texture. This actually increases the processors' output because they produce less waste, less customer waste or other related issues. ”
"All polymeric films tend to stick to their place. This is called adhesion," added Vijay Yadav, Business Manager. "For our soft film, this is not a problem." With the combination of off-line coating design, we can avoid adhesion and improve the durability of soft touch during high-speed processing. This in turn leads to higher production throughput. The film is thinner than other low quality solutions available on the market. This obviously reduces the material cost of the terminal package.
The product has a wide range of applications. Anantshree Chaturvedi, vice chairman and chief executive officer of FlexFilms, stated: "It is used in luxury packaging, decorative packaging, labels, graphic banners and high-end stationery."
F-STF films have low gloss, matt homogeneity, high haze (>90%) and very high contact (transparent) sharpness. This means that the film is easily printed on the reverse side to provide deep, rich graphics. The surface maintains its soft and luxurious feel, but it is durable enough to handle the entire value chain.
Chaturvedi added: “The annual compound annual growth rate of tactile products is expected to be between 12% and 15%, which is considered to be the highest growth part of the flexible packaging space in the United States. This is an inspirational opportunity for Flex Film's quest.”
According to Ashok Chaturvedi, Chairman and Managing Director of Uflex, “The engineers of Flex Film have adopted these two solutions by solving two very different problems, namely maintaining the soft and smooth surface texture of BOPET film while guaranteeing good tensile strength. The advantages are given to the processor at the same time."
