Efficient unfreezing and tenderizing type heat-preservation antibacterial packaging bag and preparation method thereof

Abstract

The invention relates to an efficient unfreezing and tenderizing type heat-preservation antibacterial packaging bag and a preparation method thereof. The packaging bag sequentially comprises a color rendering antibacterial layer, an unfreezing and tenderizing layer, air buffering layers, a bionic air suction layer and an efficient heat preservation layer from inside to outside, wherein the color rendering antibacterial layer and the unfreezing and tenderizing layer form an inner layer structure through blow molding, the bionic air suction layer and the efficient heat preservation layer form an outer layer structure through blow molding, the inner layer structure and the outer layer structure are bonded to form the hollow air buffering layers, and the multiple air buffering layers are arranged between the inner layer structure and the outer layer structure. The preparation method of the efficient unfreezing and tenderizing type heat-preservation antibacterial packaging bag provides a preparation process of each layer, and the method meets the requirements of increasing the heat-preservation performance of the packaging bag, promoting tenderizing of unfrozen meat, isolating the air exchange between an ambient environment and the food and the like in the transportation or storage process of frozen food, particularly meat products. The frozen meat product heat preservation effect is good and the bag is suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the field of fresh-keeping packaging, and relates to antibacterial and fresh-keeping packaging bag technology, in particular to a high-efficiency thawing and tenderizing heat preservation and antibacterial packaging bag and a preparation method thereof. Background technique [0002] Quick-frozen packaging is easily affected by environmental changes, has poor thermal insulation performance, and is prone to temperature fluctuations during use, causing food thawing-refreezing phenomena that are difficult to detect, while freezing will cause problems such as long thawing time and stiff meat. [0003] Existing fresh-keeping packaging bags are mainly made of PE and PP, which have poor thermal insulation effect; frozen food needs to be stored at low temperature throughout the process, and if there is temperature fluctuation, it will have a great impact on the overall temperature of the food; Completely separated, no relative vacuum en...
