Makou gift iron box customization has obvious advantages over glassware

The custom iron box packaging is roughly divided into two types: glassware and tinplate cans. The shelf life of canned glass is generally about 8 months, which is easy to absorb light and heat. Over time, the food in the can will become darker; while the shelf life of tinplate can be as long as two years, it has other obvious advantages:

1. Compared with other packaging containers such as plastic, glass, paper, etc., tinplate cans have greater strength, good rigidity, and are not easy to break. It can not only be used in small sales packaging, but also the main container for large shipping packaging.

2. Compared with other materials, tinplate cans have better barrier properties, such as gas barrier, moisture resistance, light-shielding and fragrance protection, reliable sealing, and more conducive to protecting products.

3. Mature technology and high production efficiency. The canned tinplate has a long history, mature technology, complete production equipment, high production efficiency, and can meet the packaging needs of various products.

The full name of tinplate can is a three-piece canned tinplate, which is a common healthy food packaging container. But don't think that all canned tinplate are the same. The quality varies depending on the paint used in the tank. After saying so much, maybe everyone will be confused again. Is there any paint used in the beverage can? For example, wall paint at home?

Iron box customization manufacturers briefly popularize the knowledge here: in commonly used beverage containers, plastic PET bottles will migrate some harmful substances such as plasticizers and bisphenol A; containers of paper materials will migrate some harmful substances, such as formaldehyde, melamine and heavy metals; but tinplate will separate some metal ions, which are harmful to human health and affect food flavor. Therefore, the inside of the tinplate can is sprayed with coating to prevent metal ions from precipitating and their impact on food flavor. In life, there are many types of foods that spray this kind of paint, such as wooden tableware, most kitchen utensils, etc.

The same tin pill needs to be sprayed, but the different paints used will have a great impact on human health. Good quality paints will precipitate trace amounts of organic matter, while poor quality paints will migrate a large amount of toxic substances such as formaldehyde, free phenols, bisphenol a, and even melamine. If some unscrupulous enterprises use non-food coatings as containers, the toxic substances precipitated into the food will be even more terrible.

In recent years, as food containers release toxic and harmful substances has received more and more attention, the country issued a series of standards on food coatings in October 2016, aiming to control chaotic markets and protect people's health.
