Metal film, paper pot and manufacturing method thereof

Abstract

The invention provides a metal film which is suitable for a paper pot and comprises 0.0007 mg / cm<2> to 0.0009 mg / cm <2> of Al and 0.001 mg / cm<2> to 0.002 mg / cm<2> of Fe. The invention further providesa paper pot made of the metal film and a manufacturing method of the paper pot. The metal film provided by the invention has good flexibility, ductility, strength and forming performance and good heat-conducting property, and a paper pot made of the metal film is simple and rapid to use, convenient to carry and good in flexibility and heat-conducting property.

Description

technical field [0001] The invention relates to the technical field of food packaging and material processing, in particular to a metal film, a paper pot containing the metal film and a paper pot manufacturing method. Background technique [0002] With the development of society, people's living standards continue to improve, and the pace of life continues to accelerate. In order to meet the needs of travel, outings, picnics and other activities, and to meet the needs of a fast and fast pace of life, people have more and more requirements for instant cooking food. more popular. Disposable paper containers that can cook food anytime and anywhere like this arise at the historic moment, but these cooking containers are all pre-processed and shaped, have a certain volume, and will occupy a certain space during carrying and transportation, causing inconvenience for carrying and transportation. Moreover, although the paper material of the current paper container is provided with ...

AI Technical Summary

Problems solved by technology

In this way, disposable paper containers that can cook food anytime and anywhere came into being. However, these cooking containers are pre-processed and have a certain volume. They will occupy a certain space during transportation and transportation, causing inconvenience in transportation and transportation.

Moreover, although the paper material of the current paper container is provided with a metal film, the formability of the metal film is poor due to the insufficient ductility, flexibility and strength of the metal film. During use, it is easy to cause the container to leak due to the damage of the paper material

And if the food in the paper container is heated, due to the poor thermal conductivity of the metal film, the speed of heating and cooking is relatively slow, and the heating effect is also very unsatisfactory.
