Problems solved by technology

[0002] Meat products need to be turned over during the production process. Traditionally, turnover baskets are used, but blood will be generated during the processing of meat products, and the flow of blood and water will pollute the environment; if the turnover distance is long, cartons are generally used, and plastic films or plastic bags are added inside the cartons. , the strength of single-use plastic bags is insufficient, because the turnover of meat products is generally large and contains skeletons, it is easier to break the bag, and the carton can increase the strength, but the carton is generally heavier, which increases the transportation cost

Abstract

The invention discloses a nonwoven fabric composite film, which sequentially comprises a nonwoven fabric layer, a bonding layer and a multilayer coextrusion film layer from top to bottom, wherein themultilayer coextrusion film layer sequentially comprises a first blocking layer, a first bonding layer, a high blocking layer, a second bonding layer and a second blocking layer from top to bottom. Anonwoven fabric composite bag prepared by the nonwoven fabric composite film provided by the invention has the advantages that in a meat product turnover process, an originally used turnover paper boxcan be replaced; the transportation cost can be effectively reduced; the cold storage or freezing effect in a product cold chain transportation process are improved; oxygen gas can be effectively prevented from entering a package through the bag with blocking layers PA and EVOH; the shelf life of a meat product can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to a non-woven composite film and its application. Background technique [0002] Meat products need to be turned over during the production process. Traditionally, turnover baskets are used, but blood will be generated during the processing of meat products, and the flow of blood and water will pollute the environment; if the turnover distance is long, cartons are generally used, and plastic films or plastic bags are added inside the cartons. , The strength of plastic bags alone is insufficient, because the turnover of meat products is generally large and contains skeletons, and it is easier to break the bag. The carton can increase the strength, but the carton is generally heavier, which increases the transportation cost. Contents of the invention [0003] The first object of the present invention is to provide a non-woven composite film. [0004] Another...
