In food packaging, retort pouches offer several unique advantages compared to metal cans and frozen food packaging:
① Preservation of food's color, aroma, flavor, and shape. Retort pouches are thinner and can achieve sterilization in a shorter time, preserving as much of the food's original color, aroma, flavor, and shape as possible.
② Convenience of use. Retort pouches can be opened easily and safely. When ready to eat, simply place the food, pouch and all, into boiling water and heat for 5 minutes before opening and consumption; some can even be consumed without heating.
③ Convenient storage and transportation. Retort pouches are lightweight, can be stacked, and occupy less space. After packaging, they take up less space than metal cans, maximizing storage and transportation space and saving on costs.
④ Energy saving. Due to their thinness, retort pouches reach the lethal temperature for bacteria more quickly during heating, consuming 30-40% less energy than metal cans.
⑤ Ease of sales. Retort pouches can be used to package or combine different foods according to market needs, allowing customers to choose freely. Furthermore, their attractive packaging significantly increases sales.
⑥ Long shelf life. Foods packaged in retort pouches do not require refrigeration or freezing, have a stable shelf life comparable to metal cans, and are convenient for both sales and home use.
⑦ Lower manufacturing cost. The composite film used to manufacture retort pouches is cheaper than metal sheets, and the production process and required equipment are much simpler, resulting in a lower price for retort pouches.
