YX-180 heart-shaped iron box
Iron boxes, many people call them tin cans, are made of tinplate as raw materials, which are packaged boxes made of tinplate by different processes such as welding, stamping and buttoning. Because it is made of tinplate as a raw material, it is also called tin box.
Iron box standard
Main parts: reflect the main body's pattern, character, mark and bar code position.
Slight scratching: the printing surface is not more than 0.3mm*20mm, without iron scratch marks.
Main view: the outer surface can be observed directly and directly under the front and front of the product.
Non dominant surface: the surface except the main view, such as the back, side, bottom and inner surface.
Characteristic
Opaque
In addition to causing food deterioration, lines also cause changes in protein and amino acids. Vitamin C is more easily irradiated by light than other food ingredients, resulting in a great loss. According to research and analysis, the loss of vitamin C in transparent glass bottled milk is 14 times higher than that in dark bottled milk. Light also causes oxidative odor of milk, and the nutritive value of milk is lost by the cracking of nuclides and methionine. The opacity of tin tins makes the preservation rate of vitamin C the highest.
Good sealing performance
The barrier of packaging containers to air and other volatile gases is very important for the preservation of nutrients and sensory quality. Comparing various kinds of fruit juice packaging containers, it is proved that the oxygen permeability of the containers directly affects the browning of fruit juice and the preservation of vitamin C. The metal cans, glass bottles, aluminum foil laminates and cartons with low oxygen permeability have better preservation of vitamin C, among which iron cans are the best.
Reduction of tin
Tin on the inner wall of tinplate acts on oxygen remaining in the container during filling to reduce the chance of oxidation of food ingredients. The reduction of tin has a good preservation effect on the flavor and color of light fruit and juice. Therefore, the fruit juice cans without painted iron have better nutritional preservation, slight browning change, better acceptance of flavor quality and longer storage period than those with other packaging materials.
