Tinplate characteristics and applications

Tinplate packaging has a wide coverage in the packaging industry due to its good sealing, preservation, protection from light, sturdiness and unique decorative metal appeal. It is an internationally popular packaging variety. With the continuous enrichment of various CC materials, DR materials and tinplate chrome iron, which has contributed to the development of packaging products and technologies, tinplate packaging is full of innovations everywhere.

Shielding from light

In addition to causing food degradation reactions, light also causes changes in proteins and amino acids. Vitamin C is more likely to interact with other food components in the presence of light, leading to significant losses. According to studies and analyses, milk in clear glass bottles loses 14 times more vitamin C than dark bottles. Light can also cause oxidative odours in milk, as well as cracks in nucleotides and methionine, and loss of nutritional value. The opaqueness of tinplate allows for maximum shelf life of vitamin C.

Good airtightness

The barrier of packaging containers to air and other volatile gases is important for the preservation of nutrients and organoleptic quality. A comparison of various juice packaging containers shows that the oxygen permeability of the packaging directly affects the browning of the juice and the preservation of vitamin C; metal cans, glass bottles and aluminium foil laminates have low oxygen permeability and the preservation of vitamin C is better in cartons, with metal cans being the best.

Tin reduction

The tin on the inside of the tinplate will interact with the oxygen left in the container during the filling process, reducing the possibility of oxidation of the food components. The reducing effect of tin is good for preserving the flavour and colour of light-coloured fruit and fruit juices. Juice cans using unpainted tin cans therefore preserve nutrients better than juice cans made from other packaging materials, with a slight variation in brown colour. The flavour quality is more acceptable and the shelf life is extended.


Thanks to these properties, tin cans provide a closed system that completely isolates environmental factors from heat and prevents food spoilage caused by light, oxygen and moisture. It is contaminated and smells foul. Food storage is more stable than other packaging materials. Vitamin C has the highest retention rate and the best preservation of nutrients.
Tinplate is used for a wide range of applications, from food and beverage packaging materials to grease cans, chemical cans and other miscellaneous cans. The advantages and characteristics of tinplate provide excellent protection for the physical and chemical properties of the contents.

Tinplate for canned food ensures food hygiene, minimises the possibility of spoilage and effectively interrupts health hazards. It also meets the convenience and speed of the modern diet. Tea containers, coffee containers, health food containers, confectionery containers, cigarette containers, gift containers and other food packaging containers are preferred.

Beverage cans Dish-shaped cans are used for filling fruit juices, coffee, tea and sports drinks, as well as colas, soft drinks, beer and other beverages. The high working capacity of tin cans allows for a wide variety of can shapes, whether tall, short, large, small, square or round, to meet the diverse needs of today’s beverage packaging and consumer preferences.

Fat Tanks

Light activates and accelerates the oxidation reaction of oils and fats, reducing their nutritional value and also producing harmful substances. More serious is the destruction of oily vitamins, especially vitamin D and vitamin A. Oxygen in the air promotes the oxidation of dietary fats and oils, reducing protein biomass and destroying vitamins. The tinplate’s opaqueness and airtight seal are the best choice for packaging fatty foods.

Chemical cans

Tinplate material is strong, protective, non-deforming, shock resistant and fire resistant, making it the best packaging material for chemical products.

Aerosol cans

Tinplate cans capable of withstanding high temperatures and pressures are particularly suitable for high-pressure aerosol cans.

Dry grocery bins

A wide range of beautifully printed biscuit tins and biscuit buckets, stationery boxes and milk powder tins are all tinplate products.
