The plastic used to make a plastic spoon is usually a thermoplastic called polypropylene. A plastic spoon would be made in the process called injection molding, where thermoplastic resin is injected into a metal die, containing a cavity in the shape of a spoon. Thermoplastics are a type of plastic where they can be formed using heat to soften and melt them. Polypropylene would be specifically chosen for a spoon because it has the properties of higher heat tolerance, meaning the spoon could be used to stir a hot cup of coffee without problems.
Usually food grade PP is used for spoon. Besides PP, PS is also used. IF any interest in buying plastic spoon moulds, pls contact sinomould-13@hotmai.com
