What are six common food packages? Give 2 examples of food products each.

Currently the international popular six more popular and promising food packaging materials.

A high-temperature sterilization of plastic cans: the material composition of PP-EVOH-PP, which is characterized by the sandwich to EVOH as a material, the gas retention is extremely good, the preservation period and the same as the cans, preserved at room temperature for two years, can be used to replace the current metal cans. This material in the United States, Japan are in the trial production stage, and patents.

Two, microwave, oven dual-use plastic disk: crystalline PET as a material, can withstand high temperatures, used for microwave and oven food, after use that is discarded. This material in the United States, the rapid development of the existing 60% of household use, Japan is also the rapid development of this material.

Three, can be squeezed bottle: material for PP-EVOH-PP, with *** extrusion technology manufacturing, air retention, good extrusion, for hot filling, not sterilized food packaging, such as sauces, sauces and so on.

Four, K-OAK hot filling system: material composition of low-density polyethylene paper-aluminum foil-containing ionized polymers, by hot filling, for high-temperature filling and high acidic food packaging, preservation period of more than one year.

Fifth, aseptic packaging: aseptic packaging has been applied to food for some time, the development trend for large-capacity, low-acid food and food with a high consistency of aseptic packaging.

Six, high-barrier laminated materials: this is the trend of food packaging materials, the development of four items: non-crystalline nylon, gas barrier for nylon 6 times, SaranHB, its gas barrier for Saran film 10 times, acrylate ester; metallized coating, used for snacks, cookies and other small packages.
