Preparation of hollow containers.
The blow molding process with air involves the heating of plastic and the initial forming of the material. The initial forming is done with a blow molding cylinder, which has an open end through which air can pass. The molding is then placed inside the mold, and air is introduced into it. As it inflates, the air pressure pushes the plastic against the walls of the mold. Once the plastic has cooled, the mold is opened, and the part is removed.
There are three manufacturing methods for blow molding:
1. Injection blow molding
2. Extrusion blow molding
3. Injection stretch blow molding
Polymers are the most commonly used materials in the production of polymer films, with the main polymers used in this industry including polyethylene, polypropylene, polyvinyl chloride (PVC), polystyrene, polyethylene terephthalate (PET), ethylene vinyl acetate (EVA), and polyvinylidene chloride (PVDC).
Plastic films are used in various applications such as product packaging, plastic bags, labels, construction, photographic films, videos, and more.
When selecting the type of polymer used in polymer films, important considerations include water vapor and oxygen permeability, strength and flexibility, maximum operating temperature, overall cost, and processability.

Plastic injection molding is a manufacturing technology used for the mass production of plastic parts with minimal errors. To effectively monitor the plastic injection process, one must be familiar with the components of a plastic injection machine and its various types.
In plastic injection molding, polymer granules are first melted and then injected into a mold under pressure. The molten plastic inside the mold cools and solidifies, forming the desired shape. Thermoplastic polymers, which can be colored and filled with other additives, are commonly used for plastic injection molding.
Almost all plastic parts we use daily are produced using plastic injection technology, ranging from automotive components and electronic device casings to kitchen appliances.
This method is the production process of hollow plastic parts. There is competition between these two methods and blow molding, thermoforming, and injection molding methods. Of course, blow molding has specific advantages, including lower residual stresses and relatively inexpensive molds. This method is known more for the production of containers, but it can also be used for the production of complex medical products, toys, and other devices. The essence of the process involves injecting a certain amount of plastic in powder or granule form into a hollow and shell-like mold. The mold is then rapidly rotated or oscillated around two main axes. The plastic adheres to the walls of the mold and forms a layer on the surface of the mold. The rotation of the mold continues during the cooling stage until the plastic takes the desired shape and solidifies. When the plastic has hardened sufficiently, cooling and rotation are stopped to remove the plastic part from the mold.

The extrusion process can be defined as the manufacturing process of a plastic product by pushing the material through a mold or die to achieve the desired shape. These products produced by a device called an extruder can be either final or intermediate products. Plastic extrusion is one of the most widely used methods for shaping plastic and polymer products.
In the extrusion of thermoplastic materials, the material is first softened with heat to make it ready for shaping. This softening process is called plasticization or thermal softening. The extruder machine carries out this process. The most commonly used type of extruder is the single-screw extruder. This extruder includes a mold responsible for shaping the plastic product.

Polyethylenes are thermoplastics obtained from the polymerization of ethylene gas. High-density polyethylene (HDPE), also known as heavy polyethylene, is named so because the molecular chain packing in heavy polyethylene is denser, making it stiffer.

BL3 is resistant to cracks caused by environmental factors and is resistant to impact and hardness, making it suitable for paper and glass production.
