Problems solved by technology

[0004] All of the above products have insufficient oxygen absorption speed, the air permeability required for the oxygen absorption reaction of the packaging material needs to be perforated or pierced, there is powder leakage, the air permeability is unstable, and the air permeability exceeds 400ml / kpa, which needs to be repeatedly pierced several times, etc. Disadvantages, especially the oxygen absorption rate related to the air permeability of the packaging material cannot meet the freshness needs of meat and fish

Abstract

The invention discloses a breathable packing material for medicine bags of a fresh keeping agent. The breathable packing material is a three-layer composite film which comprises a surface layer, a middle layer and a bottom layer, wherein one of the surface layer and the middle layer is made of Neky paper and the other layer is correspondingly made of PET (Polyethylene Terephthalate); and the bottom layer is made of PE (Poly Ethylene) or CPP (Casting Polypropylene). The change range of the breathability of the packing material for the medicine bags is 40 to 1000 ml / KPa; the material is breathable, so that hole burning processing and hole pricking processing are not needed; and the material is high in strength, so that bags cannot be torn easily, and powder cannot leak. The breathable packing material is a third-generation packing material for a water and oxygen absorbent or a deoxidant, can be used for packing various fresh keeping agents, can meet the packing requirement of a low-temperature deoxidant, a preservative and a medical deoxidant for meat, fish and other special products, and can be used as an upgrading product.

Description

technical field [0001] The invention relates to a self-permeable fresh-keeping and sealing agent medicine bag packaging material and its application, which belongs to the technical field of food preservation and product sealing and packaging, and can be used for pharmaceutical packaging of sealed products such as oxygen scavenger, double absorbent, desiccant, and air conditioning agent. It is a supporting packaging material for meat and fish preservatives. Background technique [0002] 1980.10 During the period when the applicant was the leader of the rocket engine room of the 8511 Institute, in order to implement the policy of turning the military into civilians and finding rice for cooking, the applicant proposed the subject of "Study on Deoxygenation and Sealing of Rocket Engines to Extend Storage Life". For this reason, he personally organized and led the first oxygen scavenger in my country "801" was developed. This product is formulated by using the mechanism that the c...
