High temperature cooking packaging performance test

High temperature cooking packaging material is of value in the food packaging is high compound packing materials, in terms of performance also has more stringent requirements than the ordinary bags, when detecting high temperature cooking packaging materials mainly to test the following several aspects: 1, the packing sealing test: by using compressed air to blow up and underwater extrusion method to detect material such as sealing performance, by testing can effectively seal performance comparison and evaluation on the packaging, provide a basis to determine the production technology of related indicators. 2, packing pressure resistance, resistance to drop test: by measuring pressure of high temperature cooking packaging and drop resistance, and can control the flow in the process of cracking resistance and proportion. Because during circulation situation, on a single packaging do withstand voltage test and resistance of the whole case products do drop test, and test many times in different directions, in order to withstand voltage of packaging products and falling resistance for comprehensive analysis, solve the product in the process of transportation or transfer problems because of packing damage. 3, high temperature cooking packaging mechanical strength test: mechanical strength of packaging materials including composite peel strength and sealing heat seal strength, tensile strength, etc. , if the detection index can not meet easy rupture or rupture, in the process of the packing and shipping by universal tensile tester according to national and industry standards and standard method to test and determine the qualified or not. 4, blocking performance test, high temperature cooking products tend to be highly nutritious contents such as meat products, etc. , vulnerable to the oxidation, even in the warranty period its taste also varies along with the date, so if you want to ensure that its nutrition, flavor and quality, the barrier material must be used, and therefore need to strict packaging materials in the air and moisture permeability test. 5, residual solvent testing: due to the high temperature cooking packaging printing production process and composite are two very important working procedure, and in the process of printing and composite solvent is needed, the use of solvent is a kind of have a harm to human body have certain excitant odour and polymer chemical material, foreign laws and regulations on some of the solvent such as toluene butanone has very strict control, so the printing semi-finished products, composite in the production of semi-finished products and finished products are to test the solvent residual, to ensure that the product is a health and safety.
