Makers of different products around the globe use tin cans made of
metal sheets produced by the top tin can manufacturers in India for the canning of a comprehensive range of products. Food and beverage and pharmaceuticals are considered to be the largest consumers of tin cans. Packagers around the globe always prefer tins to all other materials when it comes to accomplishing all their packaging errands. One of the most prominent reasons behind their preference is that almost all regular metals highly react with the acidic properties of the items packed, and as a result, the corrosion begins.
With the corrosion in effect, the substance packed also starts getting affected while damaging the can itself. On the other hand, tin cans are completely safe from all such hassles and considered to be ideal for all types of packaging, be it any kind of liquid or solid foodstuff. Today, food and beverages, medicines, cosmetics, and a large number of other products are packed in tin cans manufactured and supplied by the top
tin can manufacturers in India.
Sources of tin
According to the U.S. Geologic Survey, tin makes up only 2 parts per million of the earth’s crust. Tin is very rare and extracted from a large number of ores, mainly from Cassiterite (SnO2). The metal is produced by making reduction in the oxide ores with coal in a furnace.

Why tin cans score heavily over those that are made of regular metals
There are a large number of practical reasons why tin cans score heavily over other containers made of other different materials. Tin cans are extremely lightweight yet rigid enough to withstand all types of jerks and jolts during the packaging and handling of different products. These cans are boon not only for the manufacturers of different products but also for the end users (consumers) as they offer unmatched handling. Tin cans can be easily recycled and therefore play a crucial role in safeguarding the planet from carbon and greenhouse gases.
When it comes to the ease of transportation, no other metal even comes closer to tin. Manufacturers around the globe have to spend a lot not only on packaging but also on transportation. The containers made of glass, steel, or any other metal are heavy and also call for some special treatments concerning the care and concern. All these things take their expenses to the next level and as a result, profits come down. Tin cans on the other hand are lightweight and occupy a very moderate space in the vehicle.
Consumers love tin cans because they are aesthetically pleasing and easy to carry whatever the occasion. Be it cold drinks, medicines, cosmetics, or any food items, anything can be easily carried in tin cans safely and hassle-freely. Tin as per its nature does not contaminate anything packed inside even for longer durations. This is the reason it has surpassed all other metals on each and every parameter.
