Nylon Film

Bi-axially Oriented Polyamide (BOPA) Film (commonly known as Nylon) is characterised by high impact resistance and tensile strength, good stiffness and resistance towards fats, oils; dilute bases and acids. Although BOPA Film finds extensive use in food packaging, especially for fatty and oily food, distilled goods packaging, agricultural products packaging or medical products, its barrier with respect to gases deteriorates rapidly with increasing humidity. BOPA or Nylon films are hygroscopic i.e. they absorb moisture at ambient conditions which make it rather tedious for the converters to store them in dry conditions. A lot of investment by the converters handling BOPA films goes towards de-humidification and air conditioning of storage space warehouses and further proper packaging in aluminium foil etc. to keep the substrate dry.Additionally given the Indian context, BOPA Film is not easily available domestically and has to be imported more often than not. This film is expensive further posing inventory management challenges for converters.One of the very many uses that the speciality polymeric film finds is oil packaging. Typically for manufacturing packaging material for oil, the new speciality film has been laminated with Polyethene to fabricate a 2 ply packaging structure. The lamination process is also specialised to ensure superior and enhanced functionality of the packaging structure.
