Plastic jars in cosmetic

Plastic jars mostly have twist off crown cap and are used in cosmetic industries to contain many different commercial products that are often in liquid,paste,gel and powder form.Although the top may be slightly tapered, jars differ from plastic bottles in that they don't have a neck but rather a larger opening. They differ from jugs because they aren't made with handles. Plastic jars are almost always produced with removable lids. The top of the jar often has male threading, while the cosmetic plastic jars interior has female threading, creating an air-tight twist-off seal.
