The Duravant family of operating companies serve the food processing, packaging and material handling segments.
Flexible Film Materials
Flexible film packaging is an on-trend solution for all your product applications.
Flexible packaging delivers on these functional benefits:
shelf life
Extension of shelf life. This allows the products to be distributed to both domestic and export markets.
Waste reduction
Waste reduction, such as leakage or deterioration, which may occur during transportation and distribution.
packaging perception
Enhancement of overall packaging perception, which encourages the consumer to buy.
Materials
Polypropylene (PP)
Polypropylene is a clear glossy film that is extremely durable and puncture resistant.
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)
Heat sealable, inert, odour-free,and shrinks when heated.
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)
Stronger, thicker, less flexible and more fragile than low-density polythene.
Lower permeability to gases and moisture. Higher softening temperature (121°C) and can therefore be heat sterilized.

Polyester (PET)
The glossier film.
Offers excellent appearance and has very good barrier properties.
Widely used in flexible packaging due to its mechanical and dimentional characteristics at high temperatures.

Laminated films
Laminated films are two or more films glued together.
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.
