For many years, coffee, tea, ice cream and all other beverages have been stored in plastic cups, as well as paper cups, with transparent and translucent plastic lids, which are disposable, and although they have a very personalised look, they are a source of environmental pollution. With the progress of civilisation in modern society, people are paying more and more attention to environmental protection and conservation of natural resources. Therefore, there is a growing demand for the use of a container paper cover that can be naturally decomposed when discarded, reducing environmental pollution. However, the said beverage paper lid can function as a lid only when the following conditions are met. These conditions are the same as those for existing plastic lids, which are not only hygienic but also waterproof, flexible so that they do not break and remain resilient when repeatedly opened or closed, and firmly bonded to the body of the container when the lid is closed, so that the beverage does not leak out during movement, and does not expand or contract in response to changes in temperature. However, the existing paper lids are too weak in their sidewalls for the lids to be firmly fastened to the cups, so there is a problem that the lids tend to separate from the cups, and there is also a problem that the drinks leak out externally when they undergo micro-movements, so it is not a simple matter to replace the plastic lids with paper lids.
PLA-60 high-speed paper lidding machine is developed successfully by referring to the function of paper cup moulding machine and the characteristics of paper lid production basically in the medium-speed paper cup machine of our Chengda Machinery Co. It is characterised by intelligent equipment and high production efficiency. It is the best equipment for producing paper lids for paper soup bowls, instant noodle bowl lids, coffee cups and other paper container lids. Every field has a subversive innovative technology, like our development of high-speed paper lid machine, when the development of this equipment is based on two prerequisites, one is the original design intention, the other is the technical conditions.
The original design: the use of domestic paper cup paper and food-grade kraft card materials to produce paper lids, replacing all the traditional plastic lids.
Technical conditions: Because we have been producing paper cup machines for more than 20 years, we know the physics of paper cups very well, and we have the ability to carry out targeted design and improvement of the relevant angles of the cup body and the matching surface of the mouth of the paper cup roll, so as to effectively ensure that the sealing of the lid and the body of the cup produced by the paper lid machine developed by us.
