The main function of candy paper is to protect candies from being contaminated by dust, bacteria, water vapor, grease and other contaminants, losing flavor, softening, losing fragrance, softening, hardening, deformation, discoloration, and even attracting flies and ants. In order to keep the candies fresh and tasty, it is necessary to wrap them with a layer of paper to isolate them from the adverse effects of the outside world.
Candy paper is made of a variety of materials. From the earliest bare wrapping, to the current high-tech packaging, candy paper has gone through several stages of change, reflecting the progress of the candy industry and packaging technology.
The earliest candies did not have specialized packaging, but were simply wrapped in old newspapers or books. This was neither hygienic nor aesthetically pleasing, and it did not prevent the candies from getting damp or losing their flavor. It wasn't until 1916, when a polio epidemic broke out in the U.S., that people realized that naked candy could be a way to spread the virus and began to look for better ways to package it.
One of the first to carry the burden of protecting candy was an ancient wrapper - wax paper. Wax paper is parchment or plain paper impregnated with paraffin wax, which is resistant to moisture and oil. Wax paper can be wrapped in a twisted wrapping, where the candy is placed on the wax paper and twisted at both ends to form a small sealed package. Wax paper can also block the outside oils and fats on the candy contamination, and not with the candy itself contains lipids interpenetration. To this day, many candies are still wrapped in wax paper, such as Great White Rabbit milk candy and nougat.
Currently, there are two main types of environmentally friendly candy packaging materials: one is biodegradable plastic and the other is edible film. Biodegradable plastics are plastics that can be decomposed by microorganisms under natural conditions into harmless substances such as water, carbon dioxide and inorganic salts. Edible films, on the other hand, are films that can be eaten or digested by humans or animals. Both materials reduce the environmental impact of plastic waste and also protect the quality and aesthetics of the candy.
