Plastic Container Manufacturing Process

Many industries need plastic containers for their packaging needs. Plastic containers are required for cosmetic packaging. Plastic bottles are required for pharmaceutical packaging. Food and beverage packaging makes efficient use of all types of plastic containers. 

These include plastic bottles for water, plastic jars to be used as deli containers, and plastic containers for food. Plastic manufacturers are playing an important part in our modern life. Despite this knowledge being useful for companies, very few people know the exact process of making plastic containers. There are many options for plastic bottle suppliers. 

Injection Molding of Bottles

These include extrusion blow mold, injection blow molding, and stretch blow molding. Each method has its strengths. These strengths can help you choose the right company if you're looking for a distributor of plastic containers.

High-performance containers can be made with extrusion blow molding. It is lightweight and affordable. An extruder forms a hollow tube (parison). The mold cavity is made up of two halves and closes around the parison. One end is then punched off. After the container is formed by compressed air, the plastic cools and any excess plastic is cut.

Three stages are involved in injection blow molding. To create a parison, melted plastic must first be injected into the mold. To expand the mold, compressed air is blown through a core pin. The container is then transferred to the third station for ejection.

Stretch blow molding can be used to create rigid containers that are light in weight. This is commonly used to make plastic containers for carbonated beverages. To align and orient the molecules involves biaxially stretching a parison during blow molding.

Injection molding can be used to create wide-mouth containers, such as plastic jars and tubs. The material is injected into the cavity and the pressure causes the resin to conform with the mold body. These containers can be made without the use of scrap material

The newest technology for plastic bottle making is co-extrusion. This involves gluing different plastic resins together with tie layers to create bottles with heat-stable and barrier properties that can be used with hot-filled, hermetically sealed food items. There are many possible applications for this technology, including juices, sauces, and jams, toppings as well as mayonnaise and pickled products.

It will be easier to choose the right company for you if you know the different ways container suppliers make their products. This overview should give you the knowledge necessary to choose the right company for your packaging needs.
