Embodiment Construction

[0028] The present invention is described in further detail below in conjunction with accompanying drawing:

[0029] The invention provides a gas release type composite fresh-keeping film, such as figure 1 As shown, it includes the main body of the film and the self-adhesive layer, wherein the length of the main body of the film is longer than that of the self-adhesive layer, and both ends of the main body of the film stick out of the self-adhesive layer.

[0030] Such as figure 2 As shown, the film main body includes a release film with holes 2, a composite fresh-keeping coating 3, a silica gel coating 4, a polymer water-absorbing layer 5, an adhesive layer 6, and an isolation layer 7, which are sequentially coated together in layers; The other side of the release film 2 is also coated with a printing layer 1, and the printing layer 1 is a trademark or other patterns sprayed on graphite.

[0031] Wherein the release film 2 with holes is blown from an inorganic filler modif...

Abstract

The invention discloses a gas-releasing-type composite preservative pasting film. The gas-releasing-type composite preservative pasting film comprises a pasting film body and an adhesive sticker layer, wherein the adhesive sticker layer is arranged on the pasting film body. The pasting film body is of a layer structure and comprises a porous releasing film, a composite preserving coating, a silica gel coating, a macromolecule water absorption layer, an adhesive layer and an isolation layer in sequence from bottom to top, and the adhesive sticker layer comprises an adhesive sticker coating, wherein the adhesive sticker coating is arranged on the isolation layer. Sterilizing gas released by the preservative film has adjustability, the releasing period of the sterilizing gas is long, and the sterilizing gas is not left on the surfaces of food materials.

Description

technical field [0001] The invention belongs to the technical field of food preservation, and relates to a gas-releasing composite preservative film device, and also relates to a preparation method of the gas-releasing composite preservative film. Background technique [0002] With the acceleration of urbanization and the improvement of living standards in my country, the demand for fruits and vegetables in China has increased. Since 1993, my country's fruit production has ranked first in the world. According to the data of the National Bureau of Statistics, the area of ​​orchards in my country in 2014 was 12371.40 thousand hectares, the annual output of vegetables is 735.1199 million tons, but it usually takes 2-4 days for these fruits and vegetables to go from farmers to consumers. Due to the backwardness of fresh-keeping technology, a large number of fruits and vegetables will rot during this period, causing huge economic losses. [0003] The main cause of vegetable and f...
