In recent years, with the changes in people's consumption needs and the improvement of consumption levels, not only the moon cake itself has been given new connotations, but also more and higher requirements have been placed on the outer packaging of the moon cake. Moon cake packaging includes everything from iron boxes, paper boxes, wooden boxes, plastic boxes, bamboo baskets, etc. Compared with others, the iron box has its unique advantages: on the one hand, metal printing can use a variety of new inks and advanced printing processes to make the printed surface have good gloss and more beautiful appearance; on the other hand, the same price Under the circumstances, the tin box appears to be suitable for popular gift packaging. More importantly, the iron box has the characteristics of good compatibility, easy processing, easy modeling, beautiful printing, and suitable for storage.
Tin box, as the name implies, a packaging box made of iron is a box made of tinplate. Tinplate is actually tinned on the surface of the iron to protect it. According to the type, the more common ones are: moon cake cans, iron tea cans, coffee cans, biscuit cans, health care products cans, beauty cans, handle cans, piggy banks, sealed cans, milk powder cans, wine cans, Christmas cans, gifts Cans, candle cans, metal barrels, badges, music boxes, cigarette boxes, stationery boxes, CD boxes, cigarette boxes, etc.
The printing industry on the tin box is a must in today's technology. You can print a variety of different patterns according to your needs.
Tinplate boxes have obvious advantages compared with other packaging materials. One iron can be recycled, the second is environmentally friendly and harmless, and the third is advanced.
According to the shape of the tin box, the common ones can be divided into the following categories: rectangular tin box, square tin box, hand-push tin box, round tin box, special-shaped tin box (heart/ellipse/car/cartoon animal/ Characters) and so on.
In addition to causing food deterioration reactions, light can also cause changes in protein and amino acids. Vitamin C is more likely to interact with other food ingredients when exposed to light, resulting in a large amount of loss. According to research and analysis, the loss of vitamin C in clear glass bottled milk is 14 times higher than that of dark bottled milk. Light will also cause milk to produce oxidative odor, as well as nuclides, methionine, etc., which will lose nutritional value. The opacity of tinplate makes the preservation rate of vitamin C the highest.
The barrier properties of packaging containers to air and other volatile gases are very important for the preservation of nutrients and sensory quality. Comparison of various juice packaging containers proves that the oxygen transmission rate of the container directly affects the browning of juice and the preservation of vitamin C; metal cans, glass bottles, aluminum foil laminates, and cartons with low oxygen transmission rate can preserve vitamin C It is better, and among them, the iron can is the best.
The tin on the inner wall of the tinplate interacts with the oxygen remaining in the container during filling, reducing the chance of food ingredients being oxidized. The reduction effect of tin has a good preservation effect on the flavor and color of light-colored fruits and juices. Therefore, juice cans packed in unpainted iron cans have better nutrition preservation than juice cans packed with other packaging materials, and the browning changes are slight. The flavour quality is better accepted, and the shelf life is thus prolonged.
Help to the human body
Tinplate canned food, except for a few light-colored fruit and juice cans, most of them use internally painted empty cans to improve the corrosion resistance of the container; due to the electrochemical effect of metal, there will be a small amount of painted canned food in storage The iron dissolves and exists in the sealed canned food in the form of divalent iron, which is easily absorbed by the human body, and the content is about 1 to 10 ppm. As far as fruit and vegetable products are concerned, the raw material itself does not contain much iron. For iron can products, based on a 350 ml beverage can with an iron content of 5 ppm, each can provides 1.75 mg of iron, which is about 18 mg of iron per day. One-tenth of that. If the above-mentioned fruit and vegetable juice beverage cans are rich in vitamin C, iron is more easily absorbed. Therefore, iron canned food and beverages can be a good source of iron, which is of far-reaching significance for the nutrition of iron cans.
Because of these properties, tinplate cans provide a closed system that completely isolates environmental factors in addition to heat. Color-resistant foods will not deteriorate due to light, oxygen, and moisture, and will not be weakened due to the penetration of aromas or be permeated by environmental odors. The food storage stability is better than other packaging materials, the preservation rate of vitamin C is the highest, and the preservation of nutrients is also the best.
In addition, tinplate has a wide range of applications, from packaging materials for food and beverages to grease tanks, chemical tanks and other miscellaneous tanks. The advantages and characteristics of tinplate provide good protection of the contents in terms of physical and chemical properties.
