The Manufacturing Process for Plastic Bags Pipelines and the Propeller for an Outboard Maritime Motor

Different bags need a different type of material and all these bags can carry different types of products for example bags made from laminated of PA, PET, BOPP, AL, VMPET, VMCPP, PE, CPP can carry meat and seafood while the bags produced from plastic are normal shopping bags used for promotional items etc.
A plastic bag produced with synthetic thermoplastic material has two strips attached to it which are uniformly spaced with relevance to the median longitudinal axis of the sheet of plastic. In the finished bag, these extend over the whole height and are arranged in such a way that the width of the space between the lateral folds which are produced after folding the flat band about the median longitudinal axis and then the longitudinally extending weld seam closes the hose thus formed. The sheet is then bent about the longitudinal median axis to form a hose longitudinally open at one side so that the reinforcing strips are opposite one another. Lateral folds are formed in the hose to form two collapsible sidewalls and two reinforced sidewalls, and a longitudinal weld seam is made to longitudinally close the hose.
Furthermore, a bottom weld seam transverse to the longitudinal weld seam is made and the so formed bag is separated from the strip and a grip aperture is formed in the upper portion of the bag. The sheet is then bent about the longitudinal median axis to form a hose longitudinally open at one side so that the reinforcing strips are opposite one another. Lateral folds are formed in the hose to form two collapsible sidewalls and two reinforced sidewalls, and a longitudinal weld seam is made to longitudinally close the hose. It is also possible to have the upper portion contoured simultaneously with the forming of the grip aperture. (Method Of Manufacturing Plastic Carrier Bags, n.d)
The propeller for an outboard maritime motor is basically the thing that connects the boat with the water. The propeller is the thing that gives you the performance, if the propeller is bad then the boat will perform poorly and if the propeller is in good condition then the boat will perform well. The size of the propeller has two features or dimensions to it: the diameter and the pitch.&nbsp. &nbsp.
