Plastic jars refer to small packaging containers made of plastic or plastic-based raw materials, generally with sealable lids.

Among plastic jars, there are few pure plastic cans. Most of the jars are made of composite materials such as plastic, paper, and aluminum foil, while the bottom and lid of the can are made of plastic or metal. This kind of plastic can is also called Combination tank.

Types of plastic jars

The difference between plastic jars mainly lies in the can body, which is mainly divided into two categories according to its composition:

①Laminated composite material tank. It is made of several materials, such as plastic film, aluminum foil, cardboard, etc., into composite materials, and then extruded to form a can body. The can body is mostly square with rounded corners. The bottom cover is mostly plastic, which is connected with the tank body by high-frequency sealing.

②Multilayer material winding tank. It is a cylinder made of various materials by winding, and then cut into a can body according to the requirements, and then the can bottom and can lid are respectively attached.
