The patent utilizes the principle of active superposition and the method of substructure connection to insert the carboxymethyl group and the quaternary ammonium salt at the same time into the chitosan to improve the hygroscopicity and moisturizing activity, and to develop a chitosan having two kinds of hygroscopic and moisturizing active groups at the same time. derivative. The moisture absorption and moisturizing properties of these derivatives are obviously enhanced and they are expected to be developed as alternatives to hyaluronic acid.
Clear vacuum forming is a manufacturing process used to create clear plastic products. It involves heating a sheet of clear plastic until it becomes pliable, then placing it over a mold and using a vacuum to force the plastic to conform to the shape of the mold. Once the plastic cools and hardens, it retains the shape of the mold, resulting in a clear Vacuum Forming Plastic products.

The clear plastic allows for easy visibility and showcases the product inside.The normal plastic type is polycarbonate,arcylic or petg plastic.
Clear vacuum forming offers several advantages, including cost-effectiveness, versatility, and the ability to produce complex shapes with intricate details. It is a popular choice for manufacturers looking to create transparent or translucent plastic products.
