The plastic industry continues to grow very rapidly and plays an important role in many fields such as engineering, medical, agriculture and domestic. It is now very difficult to find the point at which plastic cannot be considered as an essential component. The understanding of the nature of plastic films, their production techniques, applications and their characterization is essential for producing new types of flexible packaging. This handbook has been written to discuss the production and main uses of flexible packaging. A description of the properties of the most common resins used in flexible packaging such as low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE), polypropylene (PP), PVC, polyamide (Nylon), and other plastics are also given in this handbook. First of all, I tried my best to highlight the background of flexible packaging, influencing the SDGs, the environment and at large the whole universe because we’re producing it at break-neck speed. According to the United Nations Development Program (UNDP), the world currently produces a staggering 430 million metric tons of new plastics every year and this is forecast to increase a whopping 70% by 2040.  In Chapter 1, I have discussed characterizations of Raw materials like Resins, films, chemicals, adhesives, hardeners, inks used for flexible packaging manufacturing.  In Chapter 2, manufacturing methods of polyethylene films,  the whole manufacturing process from printing to lamination, inspection, slitting and finally Finished goods production including pouch making procedures have been discussed in this section.  In Chapter 3, Quality testing procedures vs. Lab equipment’s along with Quality standards have been highlighted. Apart from these, Flexibles vs. circular economy and few key information has been conversed. I strongly believe that this handbook will obviously help to flexible packaging manufacturers including Quality & Production staffs.
