PET cans made by PET stretch blow molding machine and Tin cans made by tin can making machine are widely used for packaging purposes. For instance, PET alone covers up to 30 percent of all beverage packaging, unlike tin cans that are about 16 percent. PET nowadays are technology and consumer driven, the versatile nature of this material makes it ideal for multiple drink applications. On the other hand, tin cans are made using a can making machine production line that involves several processes integrated into one.
While PET may have the played a more significant part in drinks packaging, tin cans keep on representing an expansive bit of the food products, brew, soda pops, and spirits markets.

Various patterns are influencing the material choice for packaging. One is item differentiation; this is a noteworthy driver in packaging. This includes metal cans that can be fabricated into different shapes and sizes using can making the machine. The use of unique shapes also encourages marketers to reposition an item from ordinary to premium level to help justify the higher packing costs. Apart from the packaging’s shape, other important distinctions for an item can be made through printing, marking and other design techniques.
Recyclability and supportability are among the real trends influencing the worldwide market of tin cans. All inclusive, tin refreshment cans have a rate of collection of around 70%, which is more than twofold that of some other drink cans. Furthermore, in recent decades, tin cans have turned out to be impressively lighter. Enhancements in can-production innovation and the nonstop advancement of tin evaluations have made conceivable the down-gauging of cans in the can-production process. The decrease in weight is advantageous as it reduces the amount of waste.
On the other hand, PET containers are commonly used in drinks such as mineral water and other non-carbonated drinks. This is because they are efficient, light, safe, transparent and recyclable also. For some products, the taste and purity are very crucial.
