THE MAIN CATEGORIES OF MATERIALS

Glass:

Advantages – transparent, rigid, inert, impermeable to moisture and gases.

Disadvantages – Fragile, heavy, limited container shape

Metal:

Advantages – durable, rigid, impervious to moisture, gas and light, steam sterilization under pressure.

Disadvantages – restricted container shape, inability to use in a microwave oven, corrosion

Plastic:

Advantages – lightweight, easy molding, wide range of properties.

Disadvantages – permeable to gases, moisture and light, small resistance heating

Paper & Cardboard:

Advantages – shaped, diplonetai, welding and easily printed.

Disadvantages – very permeable to moisture and gases

Laminates (flexible materials combinations):

Advantages – only useful when the desirable properties and low cost can not be achieved with a single material.

Disadvantages – it’s not easy to recycle
