With the development of socioeconomic performance, the requirements on food safety standards are increasing. The traditional food preservation is mostly carried out in a mode of placing a deoxidizer or a drying agent in a packaging bag or a packaging box, and the mode has a certain safety risk that when the packaging bag of the deoxidizer or the drying agent is broken, food pollution is easily caused and the food cannot be eaten. Therefore, the food fresh-keeping card which is safer and more reliable is rapidly popularized and applied, and the risk of food pollution caused by powder leakage is completely eradicated by adopting paper sheets as carriers.
The fresh-keeping card is made by using paper sheets as carriers, soaking and adsorbing edible alcohol and the like; through slow release of the fresh-keeping gas, a gas phase protective layer with a certain concentration can be formed around the food to be kept fresh when the food is used, so that the food is not influenced by the PH value of the food to be kept fresh. In the industrial production process of sheet materials such as fresh-keeping cards, the following procedures are needed:
step 1: producing large sheets with larger size, wherein films are compounded on the surfaces of two sides of the large sheets;
step 2: the method comprises the steps of (1) die-cutting a large sheet material in a die-cutting mode, die-cutting a cutting mark for separating the large sheet material into small sheet materials with set sizes on the large sheet material, and reserving edge protection areas 4 on the peripheral edges of the large sheet material; specifically, the cuts include a first cut 5 and a second cut 6, and an area enclosed between the first cut 5 and the second cut 6 that are staggered is a small sheet material, as shown in fig. 1; the small pieces and the edge protection areas 4 are adhered to each other, so that the peripheral edges of the small pieces are prevented from being polluted or deformed in the material transferring process;
and step 3: separating the large sheet material into small sheet materials by using manpower, and stacking and boxing according to the requirement; specifically, as shown in fig. 2, the separation process for separating the large sheet into the small sheet includes the steps of:
(1) Stripping the edge protection zone 4 to obtain an initial sheet 1;
(2) Separating the primary separated web 2 from the initial web 1 along the second cut 6;
(3) Separating a secondary separation sheet 3 from the primary separation sheet 2 along the first cut 5, wherein the secondary separation sheet 3 is a small sheet finally obtained by separation;
and 4, step 4: according to different functional requirements, the small pieces are subjected to post-treatment, such as saturated absorption of alcohol to obtain the fresh-keeping card.
According to the industrial production process of the fresh-keeping card, in the process 3, the initial sheet material 1 needs to be separated into the primary separation sheet material 2 and the secondary separation sheet material 3 by manpower in sequence, and the sheets are stacked and boxed according to requirements, so that the production efficiency is low, and the manpower is wasted.
