Perfect shaping of light weight bottles. No partling lines, no distortion.
What is stretch blow molding and should you make your own bottles?
Stretch blow molding is the process of creating bottles (usually PET) that will be used for packaging various products, such as juices, dairy, water, etc. There are two main types of stretch blow molding: single-stage and two-stage. The following information will deal with two-stage stretch blow molding.
One of the main advantages of two-stage stretch blow molding is the process stretches the container in two directions. This biaxial stretching has several advantages. It increases the barrier properties, tolerance for drop impact, clarity, tensile strength and top load of the container. This increase in strength also allows for the reduction in material used while maintaining overall container strength. The result is a savings of 10% – 15% in material which translates into saving money.
Light weight, durable, distinctive
Pet plastic containers are a popular choice for fillers due to the numerous benefits they provide both to manufacturers and consumers, in terms of design, costs reduction and convenience.
A basic weight filling machine is comprised of at least one filling station and can be configured to as many as 96 stations or more.
To maximize filling efficiency it is important to choose the right components to work in harmony with the system and the product being filled.
Choosing the right equipment for your packaging needs can be a daunting task. There are many factors that need to be considered when selecting the optimal solution.
