Technical Field

The invention relates to the technical field of paper containers, in particular to a paper container degradation frame product and a process method thereof.

Background

In recent years, plastic pollution is becoming more serious, and plastic restrictions are promulgated in various places, so that the use of disposable plastic products, such as takeaway lunch boxes which are used in large quantities at present, is restricted or prohibited. Beverage cups, and the like. The development of paper product containers and fully biodegradable materials is increasing, the application range is expanding continuously, and the paper product containers and the fully biodegradable materials gradually replace the traditional plastics in the field of disposable tableware.

At present, the fully biodegradable material (such as PLA) has gradually replaced disposable PP plastic containers in a small amount, but due to the high price of the material and the difficulty of processing and forming processes, the material has great difficulty in being put on the market, and particularly the material is not cost-effective. While paper product containers are inherently cost effective, there are actually the following problems: the paper products container can the seepage when meetting the hot water before, has solved the seepage problem after internally drenching one deck PE membrane afterwards, but the PE mould is one kind of plastics, drenches on the paper and retrieves the decomposition after the membrane more difficult, and is very big to causing white pollution harm, and PE drenches the membrane simultaneously and can decompose when meetting high temperature, drinks for a long time and also can cause certain harmful effects to the human body. Recently, a fully biodegradable laminated film is developed, so that the problem of white pollution recovery is solved to a certain extent, and meanwhile, the harm to a human body is avoided or reduced. However, since the paper product container does not have a good sealing property when sealed with a lid, and the soup is likely to leak when slightly shaken in the state where the soup is present, there is little preference for using the paper container as the container in the state where the soup is present.

The method is a very important subject how to ensure that soup contained in a paper container does not leak when responding to environmental protection.
