THE MAIN CATEGORIES OF MATERIALS
Advantages – transparent, rigid, inert, impermeable to moisture and gases.
Disadvantages – Fragile, heavy, limited container shape
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
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
