Below is a list of Stretch Blow Molding manufacturers from Somerville, New Jersey. Stretch blow molding is a process that manufactures plastic containers, most commonly the two liter beverage bottle. It is able to produce uniform finished products that do not need to be joined and therefore do not have a visible seam. The bottles are strong enough to handle the pressure from carbonated beverages, which is about 60 psi. They also hold other beverage and food supplies like mineral water, liquor, juice, beer, cooking oils, peanut butter and milk.
