Flexible Film Materials
Flexible packaging delivers on these functional benefits:
Extension of shelf life. This allows the products to be distributed to both domestic and export markets.
Waste reduction, such as leakage or deterioration, which may occur during transportation and distribution.
Enhancement of overall packaging perception, which encourages the consumer to buy.
High print quality can be obtained with actual flexible packaging films using either flexo or rotogravure printing.
The most common materials used in our machines are PET/PE, PAPER/ALU/PE, ALU/PE and PET/ALU/PE amongst many other combinations.
Low permeability to moisture, gases and odours, which is not affected by changes in humidity.
Stretches, although less than polythene.
Good resistance to oil, and therefore can be used successfully for packaging oily products.
Polythene Low-density (LDPE)
Good moisture barrier, but has a relatively high gas permeability, sensitivity to oils and poor odour resistance.
Less expensive than most films and is therefore widely used.
High-density polythene (HDPE)
Lower permeability to gases and moisture.
Higher softening temperature (121°C) and can therefore be heat sterilized.
Offers excellent appearance and has very good barrier properties.
Widely used in flexible packaging due to its mechanical and dimentional characteristics at high temperatures.
Improves the appearance, barrier properties or mechanical strength of a package.
Aluminium foil is widely used in laminated combinations for most pharmaceutical and food products.
