Plastic jars are widely used in many industries. The main plastic used in making these jars is polypropylene (PP). This plastic is also known by several other names. The PP jars are usually injection moulded and can withstand most kinds of organic solvents and fats. If you are planning to use them for cosmetics, here are some tips to choose the right PP jar suppliers:

PP jars should have the right draft angle so that they can be released from injection moulds easily. They should also be slightly conical in shape. PP jars are highly flexible and have high tolerance. The quality of the PP jars depends on the injection moulding process. Generally, there are two cavities for a single jar and 12 cavities for double jars. The injection moulds are designed to be both flexible and precise.

PP jars are easy to decorate because of their slightly conical body. Labels can be easily applied to them. Screen printing is usually more expensive than labelling. Hot stamping is also a popular option for decoration on PP jars. Metallic foils can produce several effects and are used in cosmetic jars. Various types of lids are available for PP jars. These jars can be easily filled with liquids or other products.
