This document discusses aseptic packaging techniques. It describes how aseptic packaging involves separately sterilizing package contents and materials, then assembling and sealing them under sterile conditions. The typical aseptic package contains paper for structure, polyethylene for seals and barriers, and aluminum foil for an oxygen and light barrier to allow long shelf life without refrigeration. The aseptic process involves formulating, testing, flash pasteurizing contents, and filling and sealing packages in a continuous sterile system.

2. Definition
Technique wherein the contents of a package
and the packaging itself are sterilized
separately, and then the contents are placed
in the package and sealed under a controlled,
sterile environment.

3. Paper (70%)
Provide stiffness and the efficient
brick shape to the package.
Polyethylene (24%)
• On the innermost layer forms the seals.
• Make the package liquid-tight
Aluminum (6%)
• Silver material on the inside of the
aseptic package.
• This ultra-thin layer of foil forms a
barrier against light and oxygen,
eliminating the need for refrigeration and
preventing spoilage without
preservatives

5. Principle of Tetra Pack aseptic technology
• The food or beverage is formulated in a mixing
chamber (provide uniformity).
• It is then tasted it to make sure the QC is up to
standard.
• After the go ahead, the food or beverage is flash
pasteurized in a sterile chamber, then filled into
sterilized packaging and sealed so that nothing
bad gets in and nothing good gets out.
• The result is fresh, pure, nutritious food that stays
safe and delicious for months without
preservatives or refrigeration. The entire process
is continuous and clean, and it takes place in a
single space-efficient machine.
