There are more than 3,000 domestic thermoforming packaging machine companies, including more than 300 factories with an annual output of more than 1,000 tons. Due to the low investment costs of small thermoforming packaging machine, there are a large number of small workshops in the country. Thermoformed products are mainly used in food packaging, non-food packaging and cutting materials, and different application fields have different requirements for raw materials.
