Edistir. GPPS-HIPS for food packaging

Edistir is the brand that Eni Versalis uses for the comercialization of its GPPS-HIPS products. One of the main applications for these products is food packaging.

Each year, 1.3 billion tons of food become waste. Plastic packaging can help to reduce this huge amount of waste by protecting food and keeping it fresh.

Applications

General Purpose Polystyrene and High impact Polystyrene grades, are widely used in many areas of food packaging:

  • Dairy applications: Yogurt cup, fresh cheese containers, ice cream boxes
  • Restoration: containers and gastronomy films
  • Fresh food: Trays and small boxes
  • Disposable: Plates and cups, cutlery, coffee cups

Processing technologies

Extrusion is the most widely used technology for polystyrene processing but there is a wide variety of processing technologies such as:

  • Cast extrusion: by modeling the molten mass, plasticizing and homogenizing it in the extruder, a high transparence, gloss and stiffness is achieved in the final product.
  • Blowing extrusion: the blown film provides the passage of the molten polymer through an annular extruder. A pipe is generated with a relatively small diameter that undergoes an immediate expansion to “blow-in” of air and a stretching for traction. The film cools and solidifies. In this way, it can be folded between the pulling rolls.
  • Form Fill Seal (FFS): widely used in dairy, is a production process with high productivity. Depending on the desired use, the leaf can be composed of several layers.
  • Bi-oriented foil: Some features of the foil can be enhanced through this technology (by the stretching of a cast leaf): transparency, mechanics, permeability to oxygen and to steam vapor.
  • Thermoforming: Produces objects by heating semi-finished items until their rubber phase (through the plastic deformation). Some of the final products produced by thermoforming are coffee or yogurt cups.
