First microwavable aseptic packaging.

Tetra Pak in Lausanne, Switzerland (U.S. headquarters in Vernon Hills, Ill.) recently launched what it calls the world's first microwavable aseptic package for sauces. The pouches are made of a monolayer PET barrier film with a silicon-oxide coating and are ultrasonically sealed. The Tetra Wedge Aseptic (TWA) package competes with stand-up pouches. Its barrier is said to be effective for high- and low-acid foods and protects without refrigeration or preservatives for six months. A limited rollout started in March in North America and parts of Europe. TWA is made at 6000 packages/hr on a special Tetra Pak filling machine.
