The BFS process functions similarly to conventional extrusion blow molding, and takes place within a BFS machine. [6] First, a plastic polymer resin is heated to >160 °C and compressed to 35 MPa, [11] [15] allowing it to be extruded in tubular form, [1] and be taken over by an open two-part [16] mold to form the container.
Figure 1: Comparative Costs and Production Volumes For Processing of Plastics. The economics of plastics processing is determined by the type of process.Plastics can be processed with the following methods: machining, compression molding, transfer molding, injection molding, extrusion, rotational molding, blow molding, thermoforming, casting, forging, and foam molding.
Packaging engineers must interact with research and development, manufacturing, marketing, graphic design, regulatory, purchasing, planning and so on. The package must sell and protect the product, while maintaining an efficient, cost-effective process cycle. [2] Engineers develop packages from a wide variety of rigid and flexible materials.

A film blowing machine involves one process used to make plastic film. Extruded tubular processing is most often used with polyethylene films but can be used with other polymers. [1] The film may be laminating film, shrink film, agricultural covering film, bags or film for textiles and clothing, and other packaging materials.
The material of construction of multilayered packaging ranges from paper to plastics to metals. Most multilayered packages are not readily recyclable. [2] Basf company and Uflex recently developed multilayered food packaging from 100% recyclable materials. [3] [4]
The blow molding process begins with softening plastic by heating a preform or parison. The parison is a tube-like piece of plastic with a hole in one end through which compressed air can enter. The plastic workpiece is then clamped into a mold and air is blown into it. The air pressure inflates the plastic which conforms to the mold.
Partial overlap box with interlocking slots to temporarily close box Corrugated plastic box used as reusable packaging. Corrugated box design is the process of matching design factors for corrugated fiberboard (sometimes called corrugated cardboard) or corrugated plastic boxes with the functional physical, processing and end-use requirements.
