U.S. food packaging achieved major breakthroughs

The United States recently introduced a re-sealable food package. For example, the repackaged vacuum soft-packed chicken has a transparent film bag inside, a zipper at the wide-brimmed edge, a zipper to feed the chicken pieces, and the remaining chicken is reloaded into the bag and the zipper is re-pulled to avoid the chicken in the bag. Contact with air to keep the chicken fresh. The outer packaging is the carton board, which has a small hole that can be hung on the shelf. This kind of repackaged vacuum soft-packed chicken meat, which can be repackaged and kept fresh by consumers once eaten, is favored by the US food market and consumers, and can be described as a major and successful reform on flexible packaging.
