Correct packaging is essential to achieve both these objectives. The importance of packaging can be summarized as follows:

1

If adequately packaged and treated, the shelf-life of products may be extended, and this allows the products to be distributed to both domestic and export markets.

2

Correct packaging prevents any wastage (such as leakage or deterioration) which may occur during transportation and distribution.

3

Good packaging and presentation encourages consumers to buy.

Materials

High print quality can be obtained with actual flexible packaging films using either flexo or rotogravure printing.

Most common material used in our machines would be PET/PE, PAPER/ALU/PE, ALU/PE, PET/ALU/PE, amongst many other combinations.

Polypropylene (PP)

Polypropylene (PP)

Polypropylene is a clear glossy film with a high strength, and is 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)

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)

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

Laminated films are two or more films glued together.
  • Improves the appearance, the barrier properties, or the mechanical strength of a package.
  • Aluminium foil is widely used in laminated combinations for most pharma and food products.
