Description

Technical Field

[0001] The invention relates to the technical field of molded tableware production, and more particularly to a production process of environmentally friendly and degradable sugarcane pulp molded tableware. Background Art

[0002] Tableware is a daily necessity that people use in large quantities. The hygiene of tableware is also closely related to people's health. At present, tableware needs to be disinfected at high temperature in daily use (especially in public places such as restaurants and hotels). However, the disinfected tableware will be exposed to various secondary pollution sources during transportation, storage and use, and secondary pollution is inevitable. Therefore, the hygiene of tableware is very worrying, especially for disposable tableware. The problem of contamination is particularly prominent. How to enhance the antibacterial property of tableware has become a research direction in the industry. Pulp molded tableware refers to tableware that can replace metal and plastic for people to use by using a mold to vacuum adsorb pulp, dry it, and then process it. Because it has the advantages of protecting the ecological environment and reusing resources, green packaging materials should be vigorously developed and used. It is a major trend in the 21st century to vigorously develop pulp molded products and tableware series. In addition, with the rapid development of the economy, pollution problems are becoming more and more serious. Various fast food utensils in the catering industry are also sources of pollution. Most of the early fast food utensils were made of polystyrene foam plastics, which are easy to form white pollution. In order to solve this problem, paper has been used as packaging materials and fast food containers instead of this material. Among them, pulp molding is the main method for producing pulp molded tableware. However, the existing pulp molded tableware is easy to absorb moisture and mold, which not only seriously affects the quality of the tableware, but also threatens the health of users.
