With the current rising prices of aluminium, tinplate and other prices, the packaging costs of cans are rising, and traditional cans are opaque. Consumers cannot observe the packaging products. Plastic food cans are launched in this context. Plastic food cans are made of PET, lighter than traditional cans, which facilitates long-distance transportation and transparent packaging. Through effective combination with some transparent labels, the products look very dynamic and beautiful, and consumers can be close to each other. Observing the product, the consumer experience is even more perfect. Therefore, plastic food cans are very popular. There are also professional food can manufacturers in China. For the development of the market, it is perfectly optimistic that although the plastic food cans cannot completely replace cans, with the changes in consumer habits, this market growth is an inevitable trend.
