Can be directly microwave oven cooking bag packaging

According to Now Foods of Mississippi, some of the company's food products will be packaged in direct microwave ovens in 2007. This cooking bag is made using Shatterproof(TM) technology from Sonoco.

This is the first commercial application of Sonoco's Shatterproof coating. The coating is an organic polymer that can replace the oxide glass coating commonly used in cooking bags. This material consists of three layers, which are cast polypropylene, nylon, and seal-coated polyester in order from the inside out. One of the characteristics of Sonoco materials is their tearability. There is a tear cut on one side to ensure that the cooking bag is completely torn from one side to the other along the top.

According to Sonoco's report, its Shatterproof technology can effectively prevent flex cracking. This is a phenomenon that is invisible to the naked eye and is generally caused by stress cracking in the laminate during production, packaging, and sales. The company claims that the coating is also stronger than the previous coating type and provides better sealing performance at the same cost. Sonoco mainly supplies printed Sonotort rolls, which are then made into bags by Floeter Corp. in Elk Grove Village, Illinois.

Sonotort retort bags do not contain aluminum foil so it is safe to microwave.
