Abstract

The invention discloses a production of nanometer degradable high-obstruct packaging film and the method for preparation, specifically a degradable complex film prepared with degradable nanometer polymer as the obstruct material. Said complex film has a layer structure containing at least two outer layers and one interlayer, at least one layer among which is the obstruct layer, the obstruct layer being made up of degradable nanometer polymer, and others being made up of degradable polyolefin or polyolefin. The high-obstruct degradable film is transparent and has obstruct to oxygen and aqueous vapor. Modified by nanometer inorganic material, it can prepare 3- 7 layer film, which has high obstruct and makes the article packaged have long shelf retention period and can be degraded after one or two years, and has the same effect with dry complex and coextrusion complex film.

Description

Technical field [0001] The invention relates to a nano-degradable high-barrier packaging film and a manufacturing method thereof, and belongs to the technical field of nano-plastics. Background technique [0002] In the field of food packaging, high-temperature cooking food packaging films or bags are usually required to meet the following requirements: [0003] √It can withstand heating and steaming at 121℃ for 40 minutes, the inside and outside of the packaging bag will not be deformed, the heat-sealed part will not crack or penetrate, and the layers will not separate. [0004] √ It has a high barrier to oxygen, water vapor, food aromas, flavors of seasonings, etc. [0005] √Good chemical stability, no chemical reaction with acid-base salt solvents and grease. [0006] √Good mechanical strength and good heat sealing performance. [0007] √ Packaging for ham sausage has meat stickiness. [0008] √ Meet the requirements of food hygiene, non-toxic and harmless to the human body. ...
